Abstract: The present invention describes an efficient retroviral or viral based method that allows easy and quick identification of gene transfer in living, transduced mammalian cells. Retroviral and viral vector producer cells were generated containing a gene for an improved humanized red-shifted, Green Fluorescent Protein (hRGFP) which increases the resulting fluorescence yield after excitation. This humanized, red-shifted GFP (hRGFP) gene was cloned into several vectors and transfected into various packaging cell lines to produce vibrant green fluorescence after excitation with blue light at 450-490 nm. These vectors represent a substantial advance over currently available gene transfer marking systems or wild-type GFP marker systems none of which have been stably transfected into cells.

Abstract: The present invention relates to a novel potassium channel protein expressed exclusively in the brain, a DNA molecule having a sequence encoding this protein, a vector containing the DNA molecule, a host cell containing this vector, and a method for obtaining the potassium channel protein, wherein mRNA is extracted from human cells or tissue capable of producing the potassium channel protein of the present invention. Then, use is made of two primers between which the channel protein mRNA or a part of the mRNA region is located by using the thus extracted mRNA as a template. By carrying out a reverse transcriptase-polymerase chain reaction, the channel protein cDNA or a part thereof can be obtained. Thereafter, the channel protein can be produced by integrating the thus obtained novel potassium channel cDNA or a part of the same into an appropriate expression vector and then effecting its expression in a host cell.

Abstract: The present invention provides a method of inhibiting angiogenesis within a tissue by providing exogenous SLED to cells associated with the tissue. The presence of exogenous SLED inhibits angiogenesis within the tissue, in part by interfering with the ability of vascular endothelia to expand within the tissue. The invention also provides a method for determining the severity of a tumor be assaying for the presence of SLED within the tumor. To facilitate the inventive methods, the present invention provides pharmaceutical compositions including sources of SLED.

Abstract: The invention is related to antibodies which specifically react with connective tissue type-human mast cells, a production method of the antibodies, hybridomas which produce the antibodies, a production method of the hybridomas and antigen proteins recognized by the antibodies. After cord blood cells were cultured in the presence of SCF and IL-6, they were further cocultured with primary culture of human skin fibroblasts, and connective tissue type-human mast cells were thus obtained. A rat was immunized using the cells, hybridomas were prepared and selected by an ordinary method, and novel monoclonal antibodies were harvested from the culture supernatant of the selected hybridomas. The monoclonal antibodies specifically reacted with connective tissue type-human mast cells.

Abstract: An nNOS associated protein designated PIN-1 (Protein Inhibitor of nNOS) has been identified. It physically interacts with nNOS and inhibits its activity. Multiple lines of evidence indicate that PIN-1 is a regulator of nNOS: it is physiologically associated with nNOS, and it inhibits its catalytic activity. The extraordinary evolutionary conservation of PIN-1 and preliminary evidence that it interacts with multiple proteins, suggests that it may be a major biological regulatory protein influencing numerous physiological processes.
