FIELD OF THE INVENTION

The present invention is directed to a system and method of producing NELL peptides.

BACKGROUND OF THE INVENTION

Growth factors are substances, such as peptides, which affect the growth and differentiation of defined populations of cells in vivo or in vitro.

Bone formation occurs during development of long bones (endochondral bone formation) and flat bones (intramembranous bone formation). Further, bone formation occurs during bone remodeling which occurs continuously in adult life in order to preserve the integrity of the skeleton. Finally, bone formation occurs during bone repair, such as when bone wounds occur in a fracture or surgical situation, for example. While separate bone formation mechanisms are thought to be involved in the embryological development of long and flat bones and repair is thought to involve intramembranous bone formation.

Bone formation by either mechanism involves the activity of osteoblasts, which are regulated by growth factors. Osteoblasts are derived from a pool of marrow stromal cells (also known as mesenchymal stem cells; MSC). These cells are present in a variety of tissues and are prevalent in bone marrow stroma. MSC are pluripotent and can differentiate into a variety of cell types including osteoblasts, chondrocytes, fibroblasts, myocytes, and adipocytes. Growth factors are thought to impact osteogenic cell proliferation, differentiation and osteoblast mineralization, each of which impacts bone formation.

Autogenous bone has been used, such to repair bone in patients with craniosynostosis and cleft grafting, for example. Craniosynostosis (CS), the premature closure of cranial sutures, affects 1 in 3,000 infants and therefore is one of the most common human congenital craniofacial deformities. Premature suture closure results in cranial dimorphism, which can need surgical correction. Premature suture closure in human CS can occur by two possibly distinct processes: calvarial overgrowth and bony fusion. Recently, fibroblast growth factor 2 (FGF2) and fibroblast growth factor receptor 1(FGFR1) have been implicated in premature cranial suture fusion via CBFA1-mediated pathways (8). Missense mutation of CBFA1 is linked to cleidocranial dysplasia, manifested as delayed suture closure.

Autologous bone grafting procedures have been performed utilizing autogenous bone, such as from the iliac crest or calvaria. These donor sites are not without associated morbidity including pain, gait disturbance, thigh paresthesia for iliac crest donor sites, and infection, neurologic deficits, and hematomas for calvarial grafts. Further, donor sites can have limited volume and can contribute to increased surgical time and hospital stay.

Alloplastic grafting materials have also been utilized, and growth factors have been tested in animal models. For example, bFGF has shown potential for use in bone regeneration and repair. Another family of osteogenic growth factors have been described as bone morphogenic protein (BMP). Specifically, BMP-2 recombinant protein has been demonstrated to regenerate mandibular continuity defects and cleft palate defects with results equal to or better than autogenous particulate bone and marrow. BMPs and other osteogenic factors have been studied for use in clinical applications. However, the cost of using minimally effective dosages of BMP has been a limiting factor in clinical use.

Spinal fusion is a surgical technique in which one more of the vertebrae of the spine are united together so that motion no longer occurs between them. Indications include: treatment of a fractured (broken) vertebra, correction of deformity, elimination of pain from motion, treatment of instability, and treatment of some cervical disc herniations. The surgery can involve placement of a bone graft between the vertebrae to obtain a solid union between the vertebrae. The procedure also can involve supplemental treatments including the placement of plates, screws, cages, and recently bone morphogenic protein 2 and 7 to assist in stabilizing and healing the bone graft. Autogenous bone grafting has been the clinically preferred method, and yet has about a 30-50% failure rate. Autogenous bone grafting is a separate surgery and also carries significant morbidity.

Cartilage is a type of dense connective tissue. It is composed of chondrocytes which are dispersed in a firm gel-like matrix. Cartilage is avascular (contains no blood vessels) and nutrients are diffused through the matrix. Cartilage is found in the joints, the rib cage, the ear, the nose, in the throat and between intervertebral disks. There are three main types of cartilage: hyaline (e.g., costal cartilages, the cartilages of the nose, trachea, and bronchi, and the articular cartilages of joints), elastic (e.g., external ear, external auditory meatus, part of the Eustachian tube, epiglottis, and in some of the laryngeal cartilages) and fibrocartilage [e.g. meniscus (e.g., wrist triangular fibrocartilage complex, knee meniscus), intervertebral discs, temporomandibular joint disc, the pubic symphysis, and in some tendons and ligaments at their attachment to bones. One of the main purposes of cartilage is to provide a framework upon which bone deposition could begin (i.e., during endochondral ossification). Another important purpose of cartilage is to provide smooth surfaces for the movement of articulating bones. For example, articular cartilage, most notably that which is found in the knee joint, is generally characterized by very low friction, high wear resistance, and poor regenerative qualities. It is responsible for much of the compressive resistance and load bearing qualities of the knee joint and, without it, walking is painful to impossible. Yet another important purpose of cartilage is to provide, firm, yet flexible support (e.g., nasal cartilage, spinal discs, tracheal cartilage, knee meniscus, bronchial cartilage). For instance, cartilage such as the meniscus plays a crucial role in joint stability, lubrication, and force transmission. Under a weight bearing load, the meniscus maintains the balanced position of the femur on the tibia and distributes the compressive forces by increasing the surface contact area, thereby decreasing the average stress two to three times. Additionally, the menisci interact with the joint fluid to produce a coefficient of friction that is five times as slick as ice on ice. In another example, the intervertebral disc has several important functions, including functioning as a spacer, as a shock absorber, and as a motion unit. The gelatinous central portion of the disc is called the nucleus pulposus. It is composed of 80-90% water. The solid portion of the nucleus is Type II collagen and non-aggregated proteoglycans. The outer ligamentous ring around the nucleus pulposus is called the annulus fibrosus, which hydraulically seals the nucleus, and allows intradiscal pressures to rise as the disc is loaded. The annulus has overlapping radial bands, not unlike the plies of a radial tire, and this allows torsional stresses to be distributed through the annulus under normal loading without rupture. The disc functions as a hydraulic cylinder. The annulus interacts with the nucleus. As the nucleus is pressurized, the annular fibers serve a containment function to prevent the nucleus from bulging or herniating.

Cartilage can be damaged by wear, injury or diseases. As we age, the water and protein content of the body's cartilage changes. This change results in weaker, more fragile and thin cartilage. Osteoarthritis is a common condition of cartilage failure that can lead to limited range of motion, bone damage and invariably, pain. Due to a combination of acute stress and chronic fatigue, osteoarthritis directly manifests itself in a wearing away of the articulating surface and, in extreme cases, bone can be exposed in the joint. In another example, loss of the protective stabilizing meniscus leads to increased joint laxity or abnormal motions that lead to joint instability. The excessive motion and narrowed contact area promotes early arthritic changes. At the cellular level, there is initially a loss of cells from the superficial layer of the articular cartilage followed by cartilage splitting, subsequent thinning and erosion occurs, and finally protrusion of the underlying raw bone. The earliest arthritic changes have been noted three weeks after loss of the entire meniscus. In yet another example, because both the discs and the joints that stack the vertebrae (facet joints) are partly composed of cartilage, these areas are subject to wear and tear over time (degenerative changes). As the inner nucleus dehydrates, the disc space narrows, and redundant annular ligaments bulge. With progressive nuclear dehydration, the annular fibers can crack and tear. Loss of normal soft tissue tension may allow the spinal segment to sublux (e.g. partial dislocation of the joint), leading to osteophyte formation (bone spurs), foraminal narrowing, mechanical instability, and pain. If the annular fibers stretch or rupture, allowing the pressurized nuclear material to bulge or herniate and compress neural tissues, pain and weakness may result. This is the condition called a pinched nerve, slipped disc, or herniated disc. Radiculopathy refers to nerve irritation caused by damage to the disc between the vertebrae. Mechanical dysfunction may also cause disc degeneration and pain (e.g. degenerative disc disease). For example, the disc may be damaged as the result of some trauma that overloads the capacity of the disc to withstand increased forces passing through it, and inner or outer portions of the annular fibers may tear. These torn fibers may be the focus for inflammatory response when they are subjected to increased stress, and may cause pain directly, or through the compensatory protective spasm of the deep paraspinal muscles.

NELL peptide has been documented to stimulate bone formation and cartilage formation. Existing methods and systems of producing NELL peptides have limited success with problems. A common problem of existing NELL peptide expression systems (e.g., a mammalian cell such as a CHO cell expression system) is low productivity. Low productivity is generally found to be caused by, for example, an inappropriate construct of the nucleic acid sequence expressing a NELL peptide and/or other additional sequences, e.g., a secretory signal peptide sequence, in a particular expression system, e.g., a CHO cell.

Therefore there is a continuous need for a method and system for producing NELL peptides.

 DETAILED DESCRIPTION Definitions

As used herein, the terms “polypeptide”, “peptide” and “protein” can be used interchangeably to refer to a polymer of amino acid residues. The terms can apply to amino acid polymers in which one or more amino acid residues is an artificial chemical analogue of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers.

The term “antibody” can include various forms of modified or altered antibodies, such as an intact immunoglobulin, an Fv fragment containing only the light and heavy chain variable regions, an Fv fragment linked by a disulfide bond, a Fab or F(ab′)2 fragment containing the variable regions and parts of the constant regions, a single-chain antibody and the like. An antibody can include intact molecules as well as fragments thereof, such as, Fab and F(ab′)2, and/or single-chain antibodies (e.g. scFv) which can bind an epitopic determinant. An antibody can be of animal, e.g., mouse or rat, or of human origin, or can be chimeric or humanized. Antibodies can be polyclonal or monoclonal antibodies (mAbs), such as monoclonal antibodies with specificity for a polypeptide encoded by a NELL1 or NELL 2 protein.

The term “capture agent” refers to molecules that specifically bind other molecules to form a binding complex such as, but not limited to, an antibody-antigen complex, a lectin-carbohydrate complex, a nucleic acid-nucleic acid complex or a biotin-avidin complex.

The term “specifically binds” refers to the binding property of a biomolecule (e.g., protein, nucleic acid, antibody, etc.), which is determinative of the presence of such a biomolecule in a heterogeneous population of molecules (e.g., proteins and other biologics). Thus, under designated conditions (e.g., immunoassay conditions in the case of an antibody or stringent hybridization conditions in the case of a nucleic acid), the specified ligand or antibody specifically binds to its particular “target” molecule and will not bind in a significant amount to other molecules present in the sample.

The terms “nucleic acid” or “oligonucleotide” refer to at least two nucleotides covalently linked together. A nucleic acid of the present invention can be single-stranded or double stranded and can contain phosphodiester bonds, although in some cases, nucleic acid analogs can be included that can have alternate backbones, comprising, for example, phosphoramide, phosphorothioate, phosphorodithioate, omethylphophoroamidite linkages, and/or peptide nucleic acid backbones and linkages. Analog nucleic acids can have positive backbones and/or non-ribose backbones. Nucleic acids can also include one or more carbocyclic sugars. Modifications of the ribose-phosphate backbone can be done to facilitate the addition of additional moieties such as labels, or to increase the stability and half-life of such molecules in physiological environments, for example.

The term “specific hybridization” refers to the preferential binding, duplexing, or hybridizing of a nucleic acid molecule to a particular nucleotide sequence under stringent conditions, including conditions under which a probe can hybridize preferentially to its target subsequence, and can hybridize to a lesser extent to other sequences.

The terms “NELL1 cDNA” refer to SEQ ID NO:1, 3 and 5, and “NELL2 cDNA” can refer to SEQ ID NO:7, 9, 11 and 13.

NELL Peptides

NELL1 is a 810 aa (amino acid) peptide, distributed primarily in bone. In adults, NELL1 is expressed at high levels in craniofacial bone, and lower levels in long bone. NELL1 has known roles in osteoblast differentiation, bone formation and bone regeneration. NELL1 has known rules in forming cartilage tissues without forming bone.

NELL 2 is a 816 aa peptide, distributed in neural cells and brain.

The human NELL1 gene includes at least 3 Cbfa1 response elements in the promoter region. Cbfa1 specifically binds to these response elements. NELL1 expression can be under the control of these transcription factors expressed endogenously at least in preosteoblasts, osteoblasts and hypertrophic chondrocytes in development and in adulthood. Cleidocranial disostosis is a developmental cranial defect thought to be caused at least in part by Cbfa disruption.

A NELL1 peptide can be encoded by the NELL1 gene or cDNA and includes SEQ ID NO: 2, 4, and 6. The NELL1 peptide can include a NELL1 peptide fragment that retains the ability to induce osteogenic cell differentiation, osteoblast differentiation or bone formation. In some embodiments, the NELL1 peptide can include a NELL 1 peptide fragment that retains the ability to induce cartilage formation without forming bone. A NELL2 peptide can be encoded by the NELL2 gene or cDNA and includes SEQ ID NO: 8, 10, 12 and 14. The NELL2 peptide can include NELL2 peptide fragments that retain similar activity to the full NELL2 peptide sequence.

In some embodiments, the amino acid sequence of the NELL peptide can be selected from the group including, but not limited to human NELL1 (SEQ ID NO:2), rat NELL1 (SEQ ID NO:4), mouse NELL1 (SEQ ID NO:6), or human NELL2 (SEQ ID NO:8), rat NELL2 (SEQ ID NO:10), mouse NELL2 (SEQ ID NO:12), chicken NELL2 (SEQ ID NO:14). The amino acid sequence can also include sequences such as those with substantial similarity, such as sequences having at least about 75% sequence similarity with any portion of the sequences listed above, or contain similar active binding domains as NELL1 peptides.

The term “derivative” as used herein, refers to any chemical or biological compound or material derived from a NELL peptide, structural equivalents thereof or conformational equivalents thereof. For example, such a derivative can include any pro-drug form, PEGylated form, or any other form of a NELL peptide that renders the NELL peptide more stable or more osteophilic or lipophilic. In some embodiments, the derivative can be a NELL peptide attached to poly(ethylene glycol), a poly(amino acid), a hydrocarbyl short chain having C1-C20 carbons, or a biocompatible polymer. In some embodiments, the term “derivative” can include NELL peptide mimetics. As used herein, the term “mimetic” refers to a peptide having at least one non-peptide bond in its backbone. A peptide bond is a chemical bond formed between the carboxylic acid group of an amino acid molecule and the amino group of another amino acid molecule. A NELL peptide mimetic can be any compound that exhibits at least one or more bone forming, bone repairing, cartilage forming, and/or cartilage repairing function of a NELL peptide.

Synthetic methods for making peptide mimetics are well known in the art. The following describes an example of the basic procedure for the synthesis of a peptide, including a peptide mimetics:

Before the peptide synthesis starts, the amine terminus of the amino acid (starting material) can protected with FMOC (9-fluoromethyl carbamate) or other protective groups, and a solid support such as a Merrifield resin (free amines) is used as an initiator. Then, step (1) through step (3) reactions are performed and repeated until the desired peptide is obtained: (1) a free-amine is reacted with carboxyl terminus using carbodiimide chemistry, (2) the amino acid sequence is purified, and (3) the protecting group, e.g., the FMOC protecting group, is removed under mildly acidic conditions to yield a free amine. The peptide can then be cleaved from the resin to yield a free standing peptide or peptide mimetics.

Systems Expressing NELL Peptides

Generally, the method of invention includes providing a nucleic acid sequence encoding a NELL peptide, such as NELL1 or NELL2 peptide, in frame with a nucleic acid sequence encoding a non-insect signal peptide.

In one embodiment, the method can include transfecting an insect cell line with a nucleic acid construct encoding a NELL peptide; and culturing the insect cell line under conditions that permit expression and/or secretion of the NELL peptide. For example, the cell line can be transfected transiently or stably with the nucleic acid construct encoding a NELL peptide.

In one embodiment, the method can include providing a nucleic acid sequence encoding a NELL peptide, such as NELL1 or NELL2 peptide. The nucleic acid sequence can be a cDNA or genomic DNA, encoding at least a functional portion of a NELL peptide. For example, the nucleic acid sequence can be selected from the group including, but not limited to human NELL1 (SEQ ID NO:1), rat NELL1 (SEQ ID NO:3), mouse NELL1 (SEQ ID NO:5), or human NELL2 (SEQ ID NO:7), rat NELL2 (SEQ ID NO:9), mouse NELL2 (SEQ ID NO:11), chicken NELL2 (SEQ ID NO:13). In some embodiments, the nucleic acid sequence can also include sequences such as those with substantial sequence similarity, such as sequences having at least about 75% sequence similarity with any portion of the sequences listed above.

Further the nucleic acid can include an expression vector for expressing the nucleic acid sequence encoding a NELL peptide, such as NELL1 or NELL2 peptide. For example, the expression vector can be pIZTA/5-His (Invitrogen), and selective markers can also include blastcidin and neomycin.

Such expression systems can include a carrier such as a viral carrier or viral vector, peptide carrier or a short polymer molecule.

Nucleic acid constructs can comprise expression and cloning vectors should contain a selection gene, also termed a selectable marker, such as a gene that encodes a protein necessary for the survival or growth of a host cell transformed with the vector. The presence of this gene ensures that any host cell which deletes the vector will not obtain an advantage in growth or reproduction over transformed hosts. Typical selection genes encode proteins that (a) confer resistance to antibiotics or other toxins, e.g., ampicillin, neomycin, methotrexate or tetracycline, (b) complement auxotrophic deficiencies.

Further, the nucleic acid sequence can also include additional nucleic acids which encode reporter products to monitor levels of gene expression, or encode peptide tags which can be visualized using known methods in the art to monitor levels of peptide expression. Additional sequences can be selected so as to not interfere with the expression of the nucleic acid, or the functionality of the expressed peptide product.

A promoter is recognized by the host organism and is operatively linked to the NELL encoding nucleic acid. Promoters are untranslated sequences located upstream from the start codon of a structural gene (generally within about 100 to 1000 bp) that control the transcription and translation of nucleic acid under their control, including inducible and constitutive promoters. Inducible promoters are promoters that initiate increased levels of transcription from DNA under their control in response to some change in culture conditions, e.g. the presence or absence of a nutrient or a change in temperature. At this time a large number of promoters recognized by a variety of potential host cells are well known.

A nucleic acid can be operably linked when it is placed into a functional relationship with another nucleic acid sequence. For example, DNA for a presequence or secretory leader is operatively linked to DNA for a polypeptide if it is expressed as a preprotein which participates in the secretion of the polypeptide; a promoter or enhancer is operatively linked to a coding sequence if it affects the transcription of the sequence; or a ribosome binding site is operatively linked to a coding sequence if it is positioned so as to facilitate translation.

A NELL peptide can be expressed in any biological system. For example, a NELL peptide can be expressed in a bacterial system, a yeast system, a plant system or animal system.

In some embodiments, a NELL peptide can be expressed in a cell free expression system well known to those in the art. For example, E coli cell-free protein translation systems or wheat germ cell-free protein translation systems.

In some embodiments, a NELL peptide can be expressed in transgenic plant cell systems derived from tobacco, corn, rice or soybean.

In some embodiments, a NELL peptide can be expressed in insect cells. The NELL1 and NELL2 peptides expressed in an insect system are functional forms of the protein.

COS7 cells can be used to produce NELL1 and NELL2 proteins at low levels, such as about 10 micrograms per litter medium, but require serum-containing medium for the expression. As for the signal peptides, NELL1 and NELL2 endogenous signal peptides permit expression in COS7 cells.

In one embodiment, the invention includes a method of expressing a functional NELL peptide, such as NELL1 or NELL2 peptide, using an insect cell line. In one embodiment, the insect cell can be a high five cell, Sf9 and other Sf cells.

In one embodiment, the invention can include a nucleic acid construct for expressing a NELL peptide, such as NELL1 and/or NELL2 peptide in an insect cell. The nucleic acid sequence can be a cDNA or genomic DNA, encoding at least a functional portion of a NELL peptide. For example, the nucleic acid sequence can be selected from the group including, but not limited to human NELL1 (SEQ ID NO:1), rat NELL1 (SEQ ID NO:3), mouse NELL1 (SEQ ID NO:5), or human NELL2 (SEQ ID NO:7), rat NELL2 (SEQ ID NO:9), mouse NELL2 (SEQ ID NO:11), chicken NELL2 (SEQ ID NO:13). The nucleic acid sequence can also include sequences such as those with substantial sequence similarity, such as sequences having at least about 75% sequence similarity with any portion of the sequences listed above.

In one embodiment, the invention can include a nucleic acid construct for expressing a NELL peptide, such as NELL1 and/or NELL2 peptide in a mammalian cell such as a Chinese hamster ovary cell (CHO cell). The nucleic acid sequence can be a cDNA or genomic DNA, encoding at least a functional portion of a NELL peptide. For example, the nucleic acid sequence can be selected from the group including, but not limited to human NELL1 (SEQ ID NO:1), rat NELL1 (SEQ ID NO:3), mouse NELL1 (SEQ ID NO:5), or human NELL2 (SEQ ID NO:7), rat NELL2 (SEQ ID NO:9), mouse NELL2 (SEQ ID NO:11), chicken NELL2 (SEQ ID NO:13). In some embodiments, the nucleic acid sequence can also include sequences such as those with substantial sequence similarity, such as sequences having at least about 75% sequence similarity with any portion of the sequences listed above.

In one embodiment, the invention can include cells that express functional NELL peptides. For example, the cell can be a CHO cell. In one embodiment, the cell can be transfected with a nucleic acid construct encoding a NELL peptide. For example, the cell line can be transfected transiently or stably with the nucleic acid construct encoding a NELL peptide. In one embodiment, NELL expressing nucleic acids (e.g., cDNA(s) can be cloned into gene expression vector or viral particles that are competent to transfect cells (such as insect cells or Chinese hamster ovary cells (CHO cells)).

The nucleic acid construct can also include a nucleic acid sequence encoding a NELL peptide, such as NELL1 or NELL2 peptide, in frame with a nucleic acid sequence encoding a non-insect signal peptide that is a non-insect secretory signal peptide.

In one embodiment, the invention can include cells that express functional NELL peptides, and can secrete functional proteins.

In one embodiment, the invention can include a polypeptide (amino acid sequence) comprising a NELL peptide, such as NELL1 or NELL2 peptide, and can include a non-insect secretory signal peptide.

A preferred expression system using each specific human secretory signal peptide listed above is a CHO cell expression system.

In some embodiments, the human secretory signal peptide can include any combination of the aforelisted secretory signal peptide. In some embodiments, the human secretory signal peptide can specifically exclude any one or more of the aforelisted secretory signal peptide. For the sake of providing a concise description of the invention, listing of the above human secretory signal peptides is not repeated. Nonetheless this invention encompasses specific exclusion of any one of the human secretory signal peptide or nucleic acid sequences encoding each one of the secretory signal peptide listed above.

For the sake of providing a concise description of the invention, listing of nucleic acid sequences encoding each one of the secretory signal peptide listed above is omitted. Nonetheless, such nucleic acid sequences are publicly available and can be readily ascertained by a person of ordinary skill in the art. One public source of such nucleic acid sequence information is, e.g., http://proline.bic.nus.edu.sq/spdb/download.html.

In some embodiments, for mammalian expression systems, a protrypsin leading sequence can also be used.

In some embodiments, for production of NELL1 and/or NELL2 peptides in mammalian cells (e.g., CHO cells), the expression system for NELL1 and/or NELL2 can include the nucleic acid or cDNA that expresses an endogenous NELL signal peptide. In some embodiments, the method and system described herein specifically excludes an endogenous NELL signal peptide.

Peptide Purification

In some embodiments, the invention includes a method purifying NELL1 and/or NELL2 peptides secreted into culture media, according to standard peptide purification protocols, including, but not limited to those described below.

The method can also include collecting secreted NELL peptides and/or purifying NELL peptides for use. Peptide products can be tested for activity in a variety of functional or expression assays. For example in any assay, if a NELL peptide has a significant effect over a control substance on a given parameter, the NELL peptides can be functional to effect the measured parameter in a functional or expression assay.

In one embodiment, whether a selected cell expresses a selected nucleic acid sequence to express and/or secrete a NELL peptide can be examined. In one embodiment, the presence, amount or and/or activity of NELL peptides can be examined.

In one embodiment, NELL peptides detected and quantified by any of a number of methods well known to those of skill in the art. These can include analytic biochemical methods such as electrophoresis, capillary electrophoresis, high performance liquid chromatography (HPLC), thin layer chromatography (TLC), hyperdiffusion chromatography, and the like, or various immunological methods such as fluid or gel precipitin reactions, immunodiffusion (single or double), immunoelectrophoresis, radioimmunoassay (RIA), enzyme-linked immunosorbent assays (ELISAs), immunofluorescent assays, western blotting, and the like.

In one embodiment, Western blot (immunoblot) analysis can be used to detect and quantify the presence of NELL peptide(s) in a selected sample. Western blot analysis is well known in the art.

The assays of this invention can be scored (as positive or negative or quantity of target polypeptide) according to standard methods well known to those of skill in the art. The particular method of scoring can depend on the assay format and choice of label. For example, a Western Blot assay can be scored by visualizing the colored product produced by an enzymatic label. A clearly visible colored band or spot at the correct molecular weight can be scored as a positive result, while the absence of a clearly visible spot or band can be scored as a negative. The intensity of the band or spot can provide a quantitative measure of target polypeptide concentration.

NELL peptides, when in non-monomeric forms can be a large molecule and many of the techniques that work for purification of smaller proteins may not work as well for NELL peptides. The unusually large size of NELL oligomeric protein molecules causes it to be incompatible with the industry standard techniques used to purify smaller proteins, such as monoclonal antibodies and blood clotting factors. Specifically, the industry standard media is made by cross-linking agarose (e.g., agarose columns) into round beads with dead-end channels. The channels are lined with a functional group and interaction of this functional group with a protein forms the basis for purification. Because the channels are dead-ends, a protein molecule enters the channels by the forces of diffusion. As the protein of interest increases in size, diffusion into the channel slows and purification efficiently drops.

Instead of traditional porous media (e.g., agarose columns), other media not traditionally used for proteins may be used to purify NELL peptides in a more efficient fashion both in terms of speed and amount of NELL peptides purified/recovered. The present invention provides a method for purifying NELL peptides with a higher productivity. A low productivity in purification of protein is generally considered a production rate limiting factor in protein production. Therefore achieving a higher productivity is important in protein production.

In some embodiments, the method includes subjecting crude NELL peptides to membrane chromatography to obtain purified NELL peptides. In some embodiments, the method includes using commercially available purification media in membrane format. In some embodiments, the NELL peptide is NELL-1 peptide. In some embodiments, the NELL peptide is NELL-2 peptide. By employing membrane purification media, an efficient purification process for the NELL peptide was developed whereas analogous efforts with porous media was much less efficient.

The ion-exchange membrane can be anion-exchange membrane or cation-exchange membrane. It is not at all obvious that membrane chromatography can be used to purify NELL peptides.

Further, it is particularly surprising that cation-exchange chromatography is effective for NELL peptide purification. For example, analysis of the NELL-1 primary protein sequence indicates that its theoretical pl is 5.8. Under the pH ranges of 7-8.5 typically used to purify proteins, NELL-1 would be predicted to carry a net negative charge and therefore bind to anion exchange functional groups such as quaternary or secondary amines and not necessarily cation exchanges. Unexpectedly, however, NELL-1 is found to bind to both cation and anion exchange functional groups.

In some embodiments, purification of Nell-1 peptide/protein can be effected through a chromatography process using a medium including a metal cation bearing two, three or more charges, e.g., an earth metal cation, a rare earth metal cation. Examples of such metal ions are, e.g., Mg(++), Ca(++), Al(+++), and any rare earth ions Ln(+++). Such metal ions can be included in a buffer solution or eluting solution.

In some embodiments, purification can sequentially employ a cation exchange chromotography, an anion exchange chromotography and an hydroxyapatite medium. In other embodiments, it can also sequentially employ an anion exchange chromotography, a cation exchange chromotography and an hydroxyapatite medium. Alternatively, other combinations or steps can be introduced in between the aforementioned sequences.

The following examples are offered to illustrate, but not to limit the claimed invention.

EXAMPLES

In general, expression hosts can be bacteria, yeast and fungi, mammalian cells, plants, transgenic animals or it can also be cell-free expression systems such as those based on wheat germ or E. coli extracts. In general, expression elements can be Prokaryotic, Yeast, Mammalian and Plant promoters or viral promoters. Protein expression strategies can be: intra- or extracellular, fusion proteins and display strategies. Downstream processing of recombinant proteins can include: harvest, lysis, filtration, ultrafiltration, precipitation, and/or other protein processing/purification strategies that encompass protein capture, purification, polishing, and optimization.

Example 1 Expression of NELL Peptides

A cDNA fragment was ligated into the expression vector PiZT/V5-His (3.4 kb) (EcoRV site, Invitrogen) and included a melittin signal peptide, BamHI-EcoRI cDNA fragment of the mature rat NELL1 and a FLAG tag sequence. FIGS. 1A-1B are a depiction of the nucleic acid sequence of the cDNA construct used in this example, and corresponding predicted peptide sequence.

The High five cells (BTI-TN-5B1-4) were adapted to serum-free medium, and cells were transfected with the NELL1 peptide expression vector. Cells were treated with zeocin so as to select only cell populations expressing the NELL1 FLAG constructs. Surviving cell populations were confirmed to be stable transformants. Extracellular media was collected and tested for the presence of NELL1 peptide. NELL1 peptide was purified and used in functional assays described below.

FIG. 2A is an illustration of a CBB-stained SDS-PAGE gel of UnoQ-eluate containing purified NELL1 peptide. The medium was applied onto UnoQ column (Bio-Rad) as described herein. FIG. 2B shows a Western blot using anti-FLAG antibody depicting NELL1-FLAG expression in reference to a protein ladder. Peptide: 140 kDa (intracellular precursor), 130 kDa (mature form; 90 kDa peptide), 400 kDa (secreted form, homotrimer). In the example above, the productivity of the expression system was about 3 mg NELL1 peptide/L medium.

Relative to other expression systems which did not express or secrete peptide at all (such as bacterial expression, including yeast) or whose peptide production was extremely low (e.g., E. coli fused peptide system, CHO-dhfr cells, >10 mcg/L) production with the systems described (mammalian and insect cells) was surprisingly and substantially more effective at producing large amounts of functional protein.

Expression and Purification of Recombinant Rat NELL1 Protein. For production of the C-terminally FLAG-tagged NELL1 peptide by insect cells, a pIZT-NELL1-FLC plasmid was constructed by inserting the rat NELL1 cDNA fused to a FLAG epitope sequence derived from the pTB701-NELL1-FLC plasmid (Kuroda, BBRC, 265, 752-757, 1999) into insect expression vector pIZT/V5-His (Invitrogen). Furthermore, NELL1 original secretory signal sequence was replaced to honeybee mellitin signal sequence using PCR methods. High Five cells were purchased from Invitrogen, and were cultured in High Five Serum-Free Medium (Invitrogen). High Five cells were transfected with the pIZT-NELL1-FLC plasmid using FuGene6 (Roche). Forty-eight hours after transfection, cells were selected with 400 mg/ml of Zeocin (Invitrogen). Replace selective medium every 3 to 4 days until the stable expression cell line was established. NELL1 secretion was confirmed using immunoprecipitation and Western blot analyses. High five cells were found to express NELL1 peptides (140-kDa) in the culture medium.

The recombinant rat NELL1-FLC peptide was purified from the culture medium of Zeocin-resistant High Five cells by anion exchange chromatography using a UNO Q-1 column (Bio-Rad). NELL1 peptide was eluted at 500 mM NaCl.

For production of the C-terminally FLAG-tagged NELL1 peptide by COS7 cells, a pcDNA3.1-NELL1-FLC plasmid was constructed by inserting the rat NELL1 cDNA linked to a FLAG epitope sequence derived from the pTB701-NELL1-FLC plasmid into mammalian expression vector pcDNA3.1 (Invitrogen). COS7 cells were cultured in DMEM supplemented with 10% FBS. COS7 cells were transfected with the pcDNA3.1-NELL1-FLC using the endogenous NELL signal peptide plasmid and using electroporation method. Forty-eight hours after transfection, culture medium was subjected to immunoprecipitation and Western blot analyses for NELL1 peptide.

Example 2 Expression of NELL1 in Mammalian Systems

The mammalian expression system used for production of rhNELL1 by non-viral DNA delivery in this invention may include, but not limit to these commonly used stable suspension systems listed in Table 1. The relatively detailed protocols including vector design, host cell line culture, transfection and selection of stable cell line as well as purification of rhNell-1 in HEK 293 and CHO system are described below, but are well known to those in the art.

TABLE 1 Mammalian Expression System for production of rhNell-1 Gene System Parental vector Leader sequence amplification CHO p3Xflag-CMV preprotrypsin No/optinal DXB11 mp19-Lp human tPA DHFR/MTX HEK293 pSecTag immunoglobulin No/optinal NS/0 or Sp2/0 pdCs-Fc-X light chain of Ig DHFR/MTX and Fc fragment pEE12 N/A GS/MSX DHFR: dihydrofolate reductase; MTX: methotrexate; GS: glutamine synthetase; MSX: methionine sulphoximine.

A. CHO System #1

Vector design: A cDNA fragment was ligated into the expression vector p3XFlag-CMV (Sigma). The resulting expression construct, pCMV-rhNELL3Xflag, includes a preprotrypsin leading sequence, cDNA fragment of the mature human NELL1 coding region and a 3Xflag sequences at c-terminal.

Host Cell line: The CHO-K1 were adherent cell line and can be adapted to suspension culture in serum-free medium. The construct of pCMV-rhNell-1-3Xflag was transfected by either lipofectamin (Invitrogen) or calcium phosphates treatment. The stable cell lines were selected by adding G418 (400-600 ug/ml) into the cell culture medium for about two weeks. The stable transformants were further screened for single clones with high productivity of rhNELL1 by limiting dilution. The selected stable cell lines can be expended in laboratory or industrial scale bioreactors for rhNell-1 production.

Purification procedure: rhNELL1 peptide containing media or cell lysate were purified through anti-flag antibody M2 (Sigma) affinity column at its native condition and eluted with 3Xflag peptide.

B. CHO System #2

Vector design: FIG. 3A depicts the nucleic acid sequence of the cDNA construct and amino acid sequences of three different signal peptides that were used for the constructs.

Host Cell line: The CHO-K1 were adherent cell line and can be adapted to suspension culture in serum-free medium. The construct of pcDNA3.1-hNELL1-c-myc/His, pIL2-hNELL1-c-myc/His, or pN2-hNELL1-c-myc/His were transfected by either lipofectamin (Invitrogen) or calcium phosphates treatment. The stable cell lines were selected by adding G418 (400-600 ug/ml) into the cell culture medium for about two weeks. The stable transformants were further screened for single clones with high productivity of rhNELL1 by limiting dilution. The selected stable cell lines can be expended in laboratory or industrial scale bioreactors for rhNELL1 production.

Purification procedure: rhNELL1 peptide containing media or cell lysate were purified through immunoprecipitation through anti- c-myc agarose. FIG. 3B is a Western blot with anti-c-myc antibody detecting secreting NELL1 from transfections with different constructs after immunoprecipitation using anti-c-myc agarose. FIG. 3C is a Western blot with anti-c-myc or mouse anti-human NELL1 antibodies detecting secreting NELL1 after immunoprecipitation using rabbit anti-human Nell-1 antibody-NHS activated sepharose.

C. CHO System # 3

Vector design: Proprietary cDNA constructs expressing a NELL1 peptide was constructed according to the general procedures described above.

Host Cell line: The proprietary CHO cell lines were adherent cell line and can be adapted to suspension culture in serum-free medium. The proprietary constructs were transfected. The stable cell lines were selected by adding appropriate factors into the cell culture medium for about two weeks. The stable transformants were further screened for single clones with high productivity of rhNELL1 by limiting dilution. The selected stable cell lines can be expended in laboratory or industrial scale bioreactors for rhNELL1 production.

Purification procedure: rhNELL1 peptide containing media or cell lysate were purified through analytical and preparative protein purifications methods well known to those in the art (e.g., size, exclusion chromatography, ion exchange chromatography, affinity chromatography, immunoaffinity chromatography, high performance liquid chromatography,

Concentration procedure: rhNELL1 was concentrated using lyophilization or ultrafiltration.

D: HEK293 System

Vector design: A cDNA fragment was ligated into the expression vector pSecTagA (Invitrogen). The resulting expression construct, pSec-hNell-1-Tag, includes a murine immunoglobulin K-chain leader sequence, cDNA fragment of the mature human NELL1 coding region and dual tag of Myc and His sequences at c-terminal.

Host Cell line: The human embryo kidney cell line, HEK-293 which was adapted to serum-free medium and grown in suspension format, was transfected with the NELL1 peptide expression vector, pSec-hNell-1-Tag. Cells were either cultured for a couple of days as transient transfection before collecting conditioned medium for purification of rhNell-1 or treated with Zeocin (250 ug/ml) for selection of stable expression cell line. The stable transformants were further screened for single clones with high productivity of rhNell-1 by limiting dilution. The selected stable cell lines can be expended in laboratory or industrial scale bioreactors for rhNell-1 production.

Purification procedure: rhNell-1 peptide containing media were purified through Ni2+ affinity column at its native condition and eluted with 1M imidazole. The rhNell-1 was tested for its integrity, purity and bioactivity after extensively dialysis against at least 1000 volumes of PBS (pH 7.4) at 4° C. for 20 hrs.

In addition, the modifications of parental vectors for replacing existing leader sequence with a new one such as rat serum albumin, CD33, tPA and human interlukin-2 leader sequence or adding gene amplification target such as DHFR or GS into the backbone sequence will result in new expression vectors and systems. In this invention, the native signal peptide of human Nell-1 is not effective enough to guide the protein secretion and sometimes even the external leading sequence didn't work well, either. Thus, the construction of expression vector with in frame fusion of a small natural secretory protein such as human granulocyte-macrophage colony stimulating factor (GM-CSF) by a spacer containing intraprotein His tag and proteolytic cleavage site as “MPHHHHHHGGGDDDDKDPM” might be needed. The epitope tags used for purification of NELL1 can be one of the following: 6XHistidines, 3XFIag, Myc, GST (glutathione S-transferase), EGFP or CTHS (C-terminal half of SUMO which stands for small ubiquitin modifying protein) etc, but also could be dual of His plus Myc as listed plasmid pSecTag in Table 1 (supra).

Furthermore, the dicistronic or multicistronic vectors using IRES might be constructed for regulatory or inducible expression of rhNell-1 under certain circumstances. The genetic modifications of host cell lines for gaining longer lasting proliferation and delayed apoptosis or compatible with special requests such as Tet (tetracycline) inducible system and Flp-In specific site integration system will be considered for improvement of rhNell-1 production.

Besides the stable expression of system for production of rhNell-1 mentioned above, we would not exclude the possibility to establish a large-scale transient transfection (LST) approach using multi-milligram purified plasmid vector (pREP4) to transfect HEK 293 or BHK suspension cells with cationic polymer PEI as backup alternative or complimentary to stable system.

Example 3 Purification of NELL2 Protein from Culture Medium

High Five cells carrying pIZT-FLC-NELL2 were cultured for about three days in serum free culture medium (1 L). The culture medium was centrifuged at. 3000×g for 5 minutes and the supernatant was collected. PMSF was added to a final concentration of 1 mM. Saturated ammonium sulfate solution (80% saturation (v/v) was added and the solution kept at 4 degrees for 1 hour. The solution was centrifuged at 15000×g for 30 min. and precipitate collected. Precipitate was dissolved in 50 ml of 20 mM Tris-HCl (pH 8.0), 1 mm EDTA at 4 degree and applied onto an anion-exchange chromatography UnoQ column (6 ml, Bio-Rad) equilibrated in 20 mM Tris-HCl (pH 8.0), 1 mM EDTA at 4 degree (1 ml/min speed by FPLC (Amersham-Pharmacia). The column was thoroughly washed with the same buffer.

The binding protein was then eluted by the gradation from 0 M to 1.5 M NaCl in the same buffer. The NELL2-FLAG fractions were identified by Western blotting using anti-Flag M2 (Sigma) Ab. The positive fractions were collected into one tube. Final product was dialyzed in the seamless cellulose tube (Wako, cutoff MW 12000) against 1 L PBS for overnight at 4 degree. The product was stored at −70 degree.

Example 4 Cell Line Development and Expression of NELL-1

A series of Chinese Hamster Ovary (CHO) cell lines expressing recombinant human Nell-1 protein were developed according to procedures described above or procedures known in the art. The cell lines were screened according to known methods (please see references 1-8, below). The top 12 clones were cultured in a medium to amplify expression. The cell pools exhibiting the highest expression of human Nell-1 by ELISA were subcloned. They were then subjected to amplification, after which the cell pools were rescreened by ELISA. From this procedure, the ten highest expressing MTX-amplified subclones from transfection were expanded.

The six highest expressing subclones were adapted to grow in protein-free medium. All serum-free adapted clones were evaluated for Nell-1 expression by ELISA and by SDS gel. The clones that were observed to express the best at 1,000 nM MTX were identified as N2-1.9E10.1F9.4C2, N2-1.9E10.1F9.5H6, N2-1.9E10.1F9.5H2. All expressed Nell-1 protein at levels ≧40 ug/ml by ELISA.
