Ectodomain shedding of cell surface membrane-anchoring proteins is an important process in a wide variety of physiological events(1, 2). Tumor necrosis factor alpha (TNF-alpha) converting enzyme (TACE) is the first discovered mammalian sheddase responsible for cleavage of several important surface proteins, including TNF-alpha, TNF p75 receptor, L-selectin,(More)
Beta-lactamase inhibitory protein (BLIP) binds tightly to several beta-lactamases including TEM-1 beta-lactamase (K(i) 0.1 nm). The TEM-1 beta-lactamase/BLIP co-crystal structure indicates that two turn regions in BLIP insert into the active site of beta-lactamase to block the binding of beta-lactam antibiotics. Residues from each turn, Asp(49) and(More)
Signal transducer and activator of transcription 3 (STAT3) is considered to be an oncogene. Blocking STAT3 signaling may induce growth arrest and apoptosis in different types of tumors. Cancer cells utilize the glycolytic pathway to maintain cell growth even when adequate oxygen is present. Glycolysis inhibition is a potential therapeutic modality. In the(More)
We have previously reported effective gene transfer with a targeted molecular conjugate adenovirus vector through the c-kit receptor in hematopoietic progenitor cell lines. However, a c-kit-targeted recombinant retroviral vector failed to transduce cells, indicating the existence of significant differences for c-kit target gene transfer between these two(More)
