X-linked inhibitor of apoptosis protein inhibition induces apoptosis and enhances chemotherapy sensitivity in human prostate cancer cells.
Androgen-insensitive prostate cancer cells are highly resistant to several chemotherapeutic drugs and are characterized by the appearance of apoptosis-resistant cells. In this study, we identified the critical role of X-linked inhibitor of apoptosis protein (XIAP), a potent antiapoptotic factor, in conferring chemotherapy resistance in an androgen-insensitive DU145 human prostate cancer cell li...
متن کاملX-linked inhibitor of apoptosis protein (XIAP) is a nonredundant modulator of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis in human cancer cells.
Although the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been shown to play an important role in the immunosurveillance of neoplasia, apoptotic factors that modulate the sensitivity of cancer cells to TRAIL are poorly understood. The inhibitor of apoptosis proteins (IAPs) have generated considerable interest as potential targets for cancer therapy, but the lack of a phen...
متن کاملRottlerin sensitizes colon carcinoma cells to tumor necrosis factor-related apoptosis-inducing ligand-induced apoptosis via uncoupling of the mitochondria independent of protein kinase C.
Signaling pathways involved in survival responses may attenuate the apoptotic response to the cytotoxic tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in human colon carcinomas. In six lines examined, three were sensitive (GC(3)/c1, VRC(5)/c1, HCT116), HT29 demonstrated intermediate sensitivity, and RKO and HCT8 were resistant to TRAIL-induced apoptosis. Calphostin c [an inhibi...
متن کاملResveratrol affects protein kinase C activity and promotes apoptosis in human colon carcinoma cells.
BACKGROUND Resveratrol has been reported to have potential chemopreventive and apoptosis-inducing properties in a variety of tumor cell lines. OBJECTIVE In this study, to investigate the effects of resveratrol on protein kinase C (PKC) activity and apoptosis in human colon carcinoma cells, we used HT-29 cells and examined the PKCα and ERK1/2 signaling pathways. METHODS To test the effects o...
