Evidence for microRNA-31 dependent Bim-Bax interaction preceding mitochondrial Bax translocation during radiation-induced apoptosis
Downregulation of microRNA-31 has been linked with enhanced stress resistance, while its overexpression leads to cell death. In this study, we found mediatory role of microRNA-31 in γ-radiation-induced apoptosis in a model insect cell line Sf9 carrying well-conserved apoptotic machinery. Mature microRNA-31 is perfectly conserved amongst insects; hence we used biotinylated probes designed from B...
متن کاملJNK promotes Bax translocation to mitochondria through phosphorylation of 14-3-3 proteins.
Targeted gene disruption studies have established that the c-Jun NH2-terminal kinase (JNK) is required for the stress-induced release of mitochondrial cytochrome c and apoptosis, and that the Bax subfamily of Bcl-2-related proteins is essential for JNK-dependent apoptosis. However, the mechanism by which JNK regulates Bax has remained unsolved. Here we demonstrate that activated JNK promotes Ba...
متن کاملHypoxia inhibits tumor necrosis factor-related apoptosis-inducing ligand-induced apoptosis by blocking Bax translocation.
The hypoxic environment in solid tumors results from oxygen consumption by rapid proliferation of tumor cells. Hypoxia has been shown to facilitate the survival of tumor cells and to be a cause of malignant transformation. Hypoxia also is well known to attenuate the therapeutic activity of various therapies in cancer management. These observations indicate that hypoxia plays a critical role in ...
متن کاملJNK-Mediated BIM Phosphorylation Potentiates BAX-Dependent Apoptosis
Trophic factor deprivation (TFD) activates c-Jun N-terminal kinases (JNKs), culminating in coordinate AP1-dependent transactivation of the BH3-only BCL-2 proteins BIM(EL) and HRK, which in turn are critical for BAX-dependent cytochrome c release, caspase activation, and apoptosis. Here, we report that TFD caused not only induction but also phosphorylation of BIM(EL). Mitochondrially localized J...
متن کاملBax translocation and mitochondrial fragmentation induced by Helicobacter pylori.
BACKGROUND AND AIMS Previous in vitro and in vivo studies have revealed an association between Helicobacter pylori infection and apoptosis in gastric epithelial cells. Although involvement of the Bcl-2 family of proteins as well as cytochrome c release has been demonstrated in H pylori induced cell death, the exact role of the mitochondria during this type of programmed cell death has not been ...
