Mosquito-borne WNV (West Nile virus) is an emerging global threat. The NS3 proteinase, which is essential for the proteolytic processing of the viral polyprotein precursor, is a promising drug target. We have isolated and biochemically characterized the recombinant, highly active NS3 proteinase. We have determined that the NS3 proteinase functions in a(More)
Proteases exert control over cell behavior and affect many biological processes by making proteolytic modification of regulatory proteins. The purpose of this paper is to describe novel, important functions of matrix metalloproteinase (MMP)-26. alpha1-Antitrypsin (AAT) is a serpin, the primary function of which is to regulate the activity of(More)
A high throughput screen for compounds that induce TRAIL-mediated apoptosis identified ML100 as an active chemical probe, which potentiated TRAIL activity in prostate carcinoma PPC-1 and melanoma MDA-MB-435 cells. Follow-up in silico modeling and profiling in cell-based assays allowed us to identify NSC130362, pharmacophore analog of ML100 that induced(More)
An elevated expression of membrane type-1 matrix metal-loproteinase (MT1-MMP) is closely associated with multiple malignancies. Recently, we discovered that recycled MT1-MMP was trafficked along the tubulin cytoskeleton into the centrosomal compartment and cleaved the integral centroso-mal protein pericentrin-2. These events correlated with the induction of(More)
Evidence suggests that stimulating apoptosis in malignant cells without inflicting collateral damage to the host's normal tissues is a promising cancer therapy. Chemo- and radiation therapies that, especially if combined, induce apoptosis in tumor cells have been used for treating cancer patients for decades. These treatments, however, are limited in their(More)
The effects of TRAIL at various physiological levels were studied on 101/Hf and C3H/Sn mice during acute γ-irradiation with 750 R. An intravenous injection of TRAIL attenuated the effects of γ-irradiation on the body weight, subfractions of blood plasma, horizontal and vertical activity in the open-field test, tissue injury in the small intestine and liver,(More)
