The HGF/MET signaling pathway regulates a wide variety of normal cellular functions that can be subverted to support neoplasia, including cell proliferation, survival, apoptosis, scattering and motility, invasion, and angiogenesis. MET over-expression (with or without gene amplification), aberrant autocrine or paracrine ligand production, and missense MET(More)
Aureobasidin A (LY295337) is a cyclic depsipeptide antifungal agent with activity against Candida spp. The mechanism of action of LY295337 remains unknown. LY295337 also shows activity against the yeast Saccharomyces cerevisiae. Generation of a mutant of S. cerevisiae resistant to LY295337 is reported. Resistance was found to reside in a dominant mutation(More)
Cloned cDNAs representing the entire, homologous (80%) translated sequences of human phosphoribosylpyrophosphate synthetase (PRS) 1 and PRS 2 cDNAs were utilized as probes to localize the corresponding human PRPS1 and PRPS2 genes, previously reported to be X chromosome linked. PRPS1 and PRPS2 loci mapped to the intervals Xq22-q24 and Xp22.2-p22.3,(More)
The echinocandins are a family of cyclic lipopeptides with potent antifungal activity. These compounds inhibit the synthesis of BETA-1,3-glucan in fungi. The new semisynthetic echinocandin LY303366 was derivatized to produce a photoactivatable cross-linking echinocandin analog with antifungal activity. This analog was radioiodinated and used as a probe in(More)
Phenotypic assays have a proven track record for generating leads that become first-in-class therapies. Whole cell assays that inform on a phenotype or mechanism also possess great potential in drug repositioning studies by illuminating new activities for the existing pharmacopeia. The National Center for Advancing Translational Sciences (NCATS)(More)
