Abstract: This invention provides non-naturally occurring and isolated naturally occurring nucleic acid molecules which encode proteins designated pro-Yama, p11 Yama and p20 Yama. This invention also provides recombinant polynucleotides coding for these proteins. Also provided by this invention is a non-naturally occurring nucleic acid molecule encoding mutant CrmA protein and a dominant inhibitory Yama. Vectors and host cells containing these nucleic acid molecules are further provided. Methods of modulating a cellular function regulated by the Fas receptor pathway in a cell is provided herein. In one aspect, this method comprises introducing into the cell a nucleic acid molecule coding for a gene product having CrmA biological activity such as dominant inhibitory Yama or alternatively, the CrmA gene product.

Abstract: The invention provides a method of culturing cells which includes a proliferating step in which the number of precursor cells is expanded and a differentiating step in which the expanded precursor cells develop into neuronal cells. The proliferating step includes the step of incubating the precursor cells in proliferating medium which includes basic fibroblast growth factor (bFGF). The differentiating step includes incubating the precursor cells in differentiation media in a manner effective to form a cellular aggregate that is not adhered to any surface of the incubation vessel. In a preferred embodiment, the cells arc incubated in a roller tube. The differentiation media can also include at least one differentiating agent. The invention also provides a method for treating a neurological disorder, such as Parkinson's disease, a method of introducing a gene product into a brain of a patient, an assay for neurologically active substances, and a cell culture.

Abstract: The invention relates to regulators of UCP3 gene transcription, including novel UCP3 transcriptional promoters. UCP3 gene promoters are used in diagnosis and pharmaceutical development. In particular, transfected cells comprising UCP3 gene promoters operably linked to a reporter are used in high-throughput pharmaceutical screens.
