  • Patent number: 10874766
    Abstract: Compositions of small molecules, matrices, and isolated cells including methods of preparation, and methods for differentiation, trans-differentiation, and proliferation of animal cells into the osteoblast blast cell lineage were described. Examples of osteogenic materials that were administered to cells or co-cultured with cells are represented by compounds of Formula II, IV, and VI independently or preferably in combination with a matrix to afford bone cells. Small molecule-stimulated cells were also combined with a matrix, placed with a cellular adhesive or material carrier and implanted to a site in an animal for bone repair. Matrix pretreated with compounds of Formula II, IV, and VI were also used to cause cells to migrate to the matrix that is of use for therapeutic purposes.

    Abstract: The present invention relates to an efficient production method of xylitol by using the xylitol producing microorganism introduced with arabinose metabolic pathway to inhibit the production of arabitol, the byproduct, and instead to use arabinose only for cell metabolism in xylose/arabinose mixed medium. More precisely, to express efficiently L-arabinose isomerase (araA), L-ribulokinase (araB) and L-ribulose-5-phosphate 4-epimerase (araD) in Candida tropicalis, codon optimization was performed. Then, each gene was inserted in the gene expression cassette containing the glyceraldehyde-3-phosphate dehydrogenase promoter and the selection marker URA3, which was introduced into Candida sp. microorganism. As a result, arabitol, the byproduct interrupting the purification and crystallization of xylitol could be inhibited, making the production method of xylitol of the present invention more efficient.

  • Patent number: 8338362
    Abstract: The present invention provides: (1) antiviral agents that act by reducing or inhibiting the activity of SR proteins, more specifically, (i) antiviral agents that act by enhancing dephosphorylation of SR proteins, and (ii) antiviral agents that act by inhibiting proteins that phosphorylate SR proteins; (2) antiviral agents that act by inhibiting the expression of SR proteins, and (3) antiviral agents that act by activating proteins that antagonize SR proteins. The present invention also provides compounds that inhibit SRPKs, which phosphorylate SR proteins. Such compounds inhibit the activity of SR proteins and have antiviral activities. Various new viruses including SARS have emerged, and thus the present invention provides long-lasting broad-spectrum antiviral agents applicable to new viruses.

  • Patent number: 8323941
    Abstract: LSD1, a homolog of nuclear amine oxidases, functions as a histone demethylase and transcriptional co-repressor. LSD1 specifically demethylates histone H3 lysine 4, which is linked to active transcription. Lysine demethylation occurs via an oxidation reaction that generates formaldehyde. Importantly, RNAi inhibition of LSD1 causes an increase in H3 lysine 4 methylation and concomitant de-repression of target genes, suggesting that LSD1 represses transcription via histone demethylation. The results thus identify a histone demethylase conserved from S. pombe to human and reveal dynamic regulation of histone methylation by both histone methylases and demethylases.

  • Publication number: 20120232007
    Abstract: Methods for producing proteins and glycoproteins in Pichia pastoris that lack detectable cross binding activity to antibodies made against host cell antigens are described. In particular, methods are described wherein recombinant Pichia pastoris strains that do not display a ?-mannosyltransferase 2 activity with respect to an N-glycan or O-glycan and do not display at least one activity selected from a ?-mannosyltransferase 1, 3, and 4 activity to produce recombinant proteins and glycoproteins. These recombinant Pichia pastoris strains can produce proteins and glycoproteins that lack detectable ?-mannosidase resistant ?-mannose residues thereon and thus, lack cross binding activity to antibodies against host cell antigens. Further described are methods for producing bi-sialylated human erythropoietin in Pichia pastoris that lack detectable cross binding activity to antibodies against host cell antigens.

  • Publication number: 20120171722
    Abstract: The invention provides a method for producing polypeptide protein products and nucleic acid products having reduced levels of antigenicity in an animal being treated with a biologic product. Somatic cells are isolated from an animal, transformed into pluripotent stem cells, transfected with a nucleic acid(s) of interest, and re-differentiated towards somatic cells known to be high level producers of the desired nucleic acid product. The invention can be used to derive a general cell line to treat populations, racial specific cell lines to treat ethnic groups, or patient specific cell lines to treat individuals. Additionally, the invention provides a method to allow induced pluripotent stem cells to be re-differentiated towards their somatic cell of origin so that the cells can be used to therapeutically treat an animal without resulting teratoma formation.

  • Patent number: 8182986
    Abstract: Methods and compositions are provided for assaying for enzymes capable of releasing an enzyme donor fragment (ED) conjugated to a nucleic acid strand bonded to a surface. Conveniently, the beads are magnetic allowing segregation of the beads during the determination. Upon addition of enzyme acceptor fragment (EA) and substrate to the assay mixture, the method allows for discrimination between ED free in solution and ED bound to the bead. The complexing of ED and EA provides an active ?-galactosidase enzyme. The method permits the assay of any substance involved in a pathway that can result in a reaction releasing the ED.
