The Bcl-2-regulated apoptotic pathway.
Apoptosis (programmed cell death) is required for the removal of infected, damaged or unwanted cells and its disrupted regulation is implicated in cancer, autoimmunity and degenerative disorders. At the molecular level, multiple signaling pathways converge on a family of cysteine proteases (caspases), which when activated cause cellular destruction by cleaving a range of vital cellular substrat...
متن کاملA novel checkpoint in the Bcl-2–regulated apoptotic pathway revealed by murine cytomegalovirus infection of dendritic cells
Infection with murine cytomegalovirus (MCMV) has contributed to understanding many aspects of human infection and, additionally, has provided important insight to understanding complex cellular responses. Dendritic cells (DCs) are a major target for MCMV infection. Here, we analyze the effects of MCMV infection on DC viability, and show that infected DCs become resistant to apoptosis induced by...
متن کاملModulation of the Nur77-Bcl-2 apoptotic pathway by p38α MAPK
Orphan nuclear receptor Nur77 promotes apoptosis by targeting mitochondria through interaction with Bcl-2, an event that converts Bcl-2 from a survival to killer. However, how the Nur77-Bcl-2 apoptotic pathway is regulated remains largely unknown. In this study, we examined the regulation of the Nur77-Bcl-2 pathway by CCE9, a xanthone compound. Our results demonstrated that the apoptotic effect...
متن کاملApoptotic cytosol facilitates Bax translocation to mitochondria that involves cytosolic factor regulated by Bcl-2.
Proapoptotic members of the Bcl-2 family, including Bax, Bak, and Bid, directly trigger the mitochondrial release of apoptogenic cytochrome c and apoptosis-inducing factor into the cytoplasm. One of the crucial steps before Bax can exert its proapoptotic activity is translocation from the cytoplasm to the mitochondria, but the molecular mechanism of this translocation is not understood. To inve...
متن کاملMiR-486 regulates cardiomyocyte apoptosis by p53-mediated BCL-2 associated mitochondrial apoptotic pathway
BACKGROUND Cardiomyocyte apoptosis is a common pathological manifestation that occurs in several heart diseases. This study aimed to explore the mechanism of microRNA-486 (miR-486) in cardiomyocyte apoptosis by interfering with the p53-activated BCL-2 associated mitochondrial pathway. METHODS miR-486 mimics and inhibitors were transfected into the primary cardiomyocytes of suckling Sprague-Da...
