The urokinase receptor (uPAR) binds and localizes urokinase activity at cellular surfaces, facilitating fibrinolysis and cellular migration at sites of tissue injury. uPAR also participates in cellular signaling and regulates integrin-dependent adhesion and migration in vitro. We now report evidence that uPAR occupancy regulates cellular migration in vivo(More)
OBJECTIVE Toll-like receptor 4 (TLR4) has been reported to induce insulin resistance through inflammation in high-fat-fed mice. However, the physiological role of TLR4 in metabolism is unknown. Here, we investigated the involvement of TLR4 in fasting metabolism. RESEARCH DESIGN AND METHODS Wild-type and TLR4 deficient (TLR4(-/-)) mice were either fed or(More)
This review focuses on the location and interaction of three functional sites in F1-ATPases. These are catalytic sites which are located in beta subunits, noncatalytic nucleotide-binding sites which are located at interfaces of alpha and beta subunits and modulate the hydrolytic activity of the enzyme, and a site that binds inhibitory amphipathic cations(More)
Nicotinamide phosphoribosyltransferase (NAMPT) is a promising antitumor target. Novel NAMPT inhibitors with diverse chemotypes are highly desirable for development of antitumor agents. Using high throughput screening system targeting NAMPT on a chemical library of 30000 small-molecules, we found a non-fluorescent compound F671-0003 and a fluorescent(More)
