Abstract: This disclosure provides improved methods for obtaining populations of dopaminergic neurons from pluripotent stem cells. The process involves taking a population of neural precursor cells derived from a line of human embryonic stem cells, and culturing the cells in a medium that contains a neurotrophin, either cyclic adenosine monophosphate (cAMP) or a compound that elevates intracellular cAMP levels, and optionally an antioxidant such as ascorbic acid. Cell populations have been obtained that contain a high proportion of cells staining for tyrosine hydroxylase, which is a feature of dopaminergic neurons. The neural progenitors and terminally differentiated neurons of this invention can be generated in large quantities for use in drug screening and the treatment of clinically important neurological disorders, such as Parkinson's disease.

Abstract: The present invention provides compositions and methods for direct transfection of mitochondria and chloroplast DNA in living cells. More particularly, the present invention is based on the use of viral vectors that specifically bind to receptors uniquely found on the target organelle. In one embodiment, as shown in FIG. 1, a eukaryotic cell containing an organelle (1) that has been modified to express a viral receptor (2) on the organelle's surface is provided. A viral vector (6) comprising a desired recombinant DNA construct (3) is introduced into the cytosol of the cell, wherein the viral vector binds to its receptor and introduces the recombinant DNA into the interior of the organelle.

Abstract: A plasmid, viral or linear DNA molecule containing a nucleic acid sequence derived from the promoter region of the hCol1?2 gene, which is selectively transported into the nuclei of cells in the osteoblast lineage. The sequence can be used independently as a nuclear entry sequence only, and/or as a nuclear entry sequence without regard to position, in a vector or linear DNA that directs gene expression and nuclear entry. The disclosure further includes a chimeric DNA sequence derived by the addition of osteoblast-specific enhancer sequences to the nuclear entry sequence/promoter sequence, to increase osteoblast-specific expression while retaining osteoblast-specific nuclear import. An enhancer sequence is derived from the promoter region of the human Core Binding Factor alpha 1 (Cbfa1/Runx2) gene. The Cbfa1/Runx2 promoter can be added to the sequence derived from, or alternatively, comprising the promoter region of the hCol1?2 gene. Also provided are methods of use of the novel sequences.

Abstract: The present invention relates to prevention and treatment of strokes and ischemic diseases and to post-ischemic therapeutic treatment.

In particular, the invention provides methods and compositions used to deliver an adeno-associated virus vector (AAV) comprising a nucleotide sequence encoding glutamic acid decarboxylase (GAD) to cells in the subthalmic nucleus of the basal ganglia, mesaphilia and thalamus.

Abstract: A recombinant nucleic acid comprising nucleotides corresponding to a 3.2 kb 3? untranslated region present in mouse calcium calmodulin kinase II alpha subunit-encoding mRNA is provided. An isolated nucleic acid which hybridizes to the 3? untranslated region of mouse calcium calmodulin kinase II alpha subunit-encoding mRNA under conditions comprising two post-hybridization washes of 15 minutes each at 42° C. in 0.2× standard sodium citrate buffer is also provided.

Abstract: A enhanced method for observing tumor progression, angiogenesis and/or metastasis in animal models in real time is described. The invention employs a skin flap over the area to be observed that can be opened and closed reversibly. The invention also permits simultaneous observation of more than one tumor by use of multiple colors.

Abstract: The invention features a tribonectin and a method of tribosupplementation carried out by administering tribonectins directly to an injured or arthritic joint.

Abstract: A transgenic screen and method for screening biological and chemical test substances or molecules for their ability to influence or modulate the production of BDNF in cells, includes a fusion gene having a zebrafish BDNF gene fragment (promoter) and a fluorescent marker gene inserted downstream of the BDNF gene fragment. When the fusion gene is injected into a zebrafish embryo, the BDNF promoter causes the production of fluorescent protein in various cell types. The embryo is exposed to a test substance for determining the effect thereof on the production of the fluorescent marker protein.

Abstract: Methods for testing candidate drugs for treatment of age-related macular degeneration are provided. Ccl2-deficient, and Ccr2-deficient mice are used to determine the effect of candidate drugs and treatments on development of age-related macular degeneration. Also provided is a Ccl2-deficient, Ccr2-deficient dual knockout mouse, which is a useful animal model for age-related macular degeneration.

Abstract: This invention relates, in part, to newly identified methods of using quinolone antibiotics, particularly a gemifloxacin compound against certain pathogenic bacteria, particularly quinolone resistant S. pneumoniae and rare H. influenzae strains.

Abstract: Methods for treating Parkinson's disease (PD) are provided. Recombinant adeno-associated virus (rAAV) virions are used to deliver genes encoding dopamine-synthesizing enzymes to the central nervous system of a primate. Once delivered, the genes are expressed, which then results in dopamine synthesis and amelioration in the clinical signs and symptoms of PD. The methods of the present invention can be used to deliver the three central dopamine synthesizing enzymes: tyrosine hydroxylase, aromatic L-amino acid decarboxylase, and guanosine triphosphate cyclohydrolase I thereby enhancing dopamine biosynthesis and providing for enhanced therapeutic efficacy.
