Engineering ML-IAP to produce an extraordinarily potent caspase 9 inhibitor: implications for Smac-dependent anti-apoptotic activity of ML-IAP.
ML-IAP (melanoma inhibitor of apoptosis) is a potent anti-apoptotic protein that is strongly up-regulated in melanoma and confers protection against a variety of pro-apoptotic stimuli. The mechanism by which ML-IAP regulates apoptosis is unclear, although weak inhibition of caspases 3 and 9 has been reported. Here, the binding to and inhibition of caspase 9 by the single BIR (baculovirus IAP re...
متن کاملMelanoma inhibitor of apoptosis protein (ML-IAP) is a target for immune-mediated tumor destruction.
The identification of antigens associated with tumor destruction is a major goal of cancer immunology. Vaccination with irradiated tumor cells engineered to secrete granulocyte-macrophage colony stimulating factor generates potent, specific, and long-lasting antitumor immunity through improved tumor antigen presentation by dendritic cells and macrophages. A phase I clinical trial of this immuni...
متن کاملThe inhibitor of apoptosis protein Livin (ML-IAP) plays a dual role in tumorigenicity.
The inhibitor of apoptosis protein (IAP) family can inhibit apoptosis induced by a variety of stimuli. We and others previously described the IAP Livin (ML-IAP). We found that Livin is unique among the IAP members as, on a strong apoptotic stimulus, it is specifically cleaved by caspases to produce a truncated protein with paradoxical proapoptotic activity (tLivin). We also showed that Livin en...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولML-IAP, a novel inhibitor of apoptosis that is preferentially expressed in human melanomas
BACKGROUND Inhibitors of apoptosis (IAPs) are a family of cell death inhibitors found in viruses and metazoans. All IAPs have at least one baculovirus IAP repeat (BIR) motif that is essential for their anti-apoptotic activity. IAPs physically interact with a variety of pro-apoptotic proteins and inhibit apoptosis induced by diverse stimuli. This allows them to function as sensors and inhibitors...
