Abstract: The present invention relates to inducible transcription control sequences for the regulation of gene expression. Specifically, it relates to an transcription control sequence comprising at least two tet operator sequence motifs allowing the binding of tetracycline-dependent transcriptional regulators, wherein each of the tetracycline-dependent transcriptional regulators binds with respect to its neighbor to an opposite face of the DNA helix, and a minimal promoter comprising a TATA box which is linked at its 5? end to a general transcription factor binding site. Further, the present invention relates to a vector, a host cell, a plant or a non-human transgenic animal comprising the transcription control sequence. Also contemplated is a method for regulating the expression of a nucleic acid sequence being operatively linked to the transcription control sequence of the present invention in a host cell, a plant or a non-human transgenic animal.

Abstract: In vitro SELEX has been used to discover high affinity RNA aptamers interacting with the tetracycline repressor protein in a tetracycline-dependent manner. Using in silico RNA folding predictions to guide the design of both aptamer truncations and mutants, minimized tetracycline repressor protein high affinity binding aptamers have been defined. Using one such aptamer, inducible post-transcriptional regulation in vivo has been demonstrated that is predicated on a direct interaction between a tetracycline repressor protein and a RNA aptamer element. These aptamer components can be integrated in any organism to inducibly regulate RNA translation of a gene of interest.

Abstract: Disclosed are compositions, methods and systems for preventing or treating cardiac dysfunction, particularly cardiac pacing dysfunction by genetic modification of cells of targeted regions of the cardiac conduction system. In particular, a bio-pacemaker composition is delivered to cardiac cells to increase the intrinsic pacemaking rate of the cells, wherein the bio-pacemaker composition increases expression of a channel or subunit thereof that produces funny current and a T-type Ca2+ channel or subunit thereof, and expresses one or more molecules that suppresses the expression of the wild type potassium channel.
Abstract: A method of differentiating embryonic stem cells into neural and motor cells is disclosed. In one embodiment, the invention comprises culturing a population of cells comprising a majority of cells that are characterized by an early rosette morphology and are Sox1?/Pax6+ in the presence of FGF2, FGF4, FGF8, FGF 9, or RA wherein the cells are characterized by an neural tube-like rosette morphology and are Pax6+/Sox1+.
Abstract: Methods and composition for nucleic acid isolation are provided.

Methods according to the invention may also be used for differential isolation of RNA and DNA.
Abstract: Systems for pathotropic (disease-seeking) targeted gene delivery are provided, including viral particles with extremely high titers. In particular, the viral particles are engineered to specifically deliver therapeutic or diagnostic agents to a disease site, such as cancer metastic sites. Personalized dosing regimens are also provided to treat diseases such as cancer efficaciously with reduced adverse side effects.
Abstract: The miR15 and miR16 micro RNA genes are located at 13q14 within a 30 kb region of loss characteristic of cells from certain cancers, such as cells from chronic lymphocytic leukemia or prostate cancer. Chronic lymphocytic leukemia or prostate cancer can be diagnosed by detecting a reduction in miR15 or miR16 gene copy number, by determining miR15 or miR16 gene mutational status, or by detecting a reduction in the RNA transcribed from these genes. The miR15 or miR16 gene products can inhibit the neoplastic or tumorigenic growth of cancers such as chronic lymphocytic leukemia or prostate cancer cells when administered to subjects suffering from these diseases.
Abstract: This invention relates to a mammalian artificial chromosome vector, which retains a human chromosome 7 fragment comprising human cytochrome P450 genes and is transmittable to progeny, wherein the human chromosome 7 fragment retains a region of approximately 1 Mb±500 Kb in size comprising at least a human CYP3A gene cluster, which region is located between chromosome markers AC004922 and AC073842, and to a non-human mammalian animal retaining the vector.

Abstract: A method of preserving cone cells in the eye of a mammal suffering from a retinal degenerative disease comprises isolating from the bone marrow of the mammal a lineage negative hematopoietic stem cell population that includes endothelial progenitor cells, transfecting cells from the stem cell population with a gene that operably encodes an antiangiogenic fragment of human tryptophanyl tRNA synthetase (TrpRS), and subsequently intravitreally injecting the transfected cells into the eye of the mammal in an amount sufficient to inhibit the degeneration of cone cells in the retina of the eye. The treatment may be enhanced by stimulating proliferation of activated astrocytes in the retina using a laser.

Abstract: Disclosed is an expression vector system for variants of coagulation factor VIII (FVIII) and von Willebrand factor (vWF). In detail, mutant vWF the size of which is significantly reduced by deleting exons but which has remarkably increased FVIII stabilizing and activating efficiency, and an expression vector system useful for the treatment of hemophilia which is capable of expressing the same along with FVIII are disclosed. Use of the mutant vWF with a reduced size enables effective expression of FVIII in a viral vector and significantly enhanced FVIII activity. Further, the viral vector may be effectively used to treat hemophilia through gene therapy.
