Mechanisms promoting escape from mitotic stress-induced tumor cell death.
Non-small cell lung cancer (NSCLC) is notorious for its paltry responses to first-line therapeutic regimens. In contrast to acquired chemoresistance, little is known about the molecular underpinnings of the intrinsic resistance of chemo-naïve NSCLC. Here we report that intrinsic resistance to paclitaxel in NSCLC occurs at a cell-autonomous level because of the uncoupling of mitotic defects from...
متن کاملRetinitis pigmentosa‑associated rhodopsin mutant T17M induces endoplasmic reticulum (ER) stress and sensitizes cells to ER stress-induced cell death.
Retinitis pigmentosa (RP) is a group of inherited diseases that primarily affect light‑sensitive rods and cones in the retina. Rhodopsin mutations, including the T17M mutation, are associated with the autosomal dominant form of retinitis pigmentosa (ADRP) and have been linked to abnormal protein folding. However, the molecular mechanisms underlying T17M rhodopsin‑induced retinal degeneration ar...
متن کاملChikungunya-induced cell death is limited by ER and oxidative stress-induced autophagy.
It has been recognized that macroautophagy constitutes an important survival mechanism that allows both the maintenance of cellular homeostasis and the regulation of programmed cell death pathways (e.g., apoptosis). Although several pathogens have been described to induce autophagy, the prosurvival function of this process in infectious models remains poorly characterized. Our recent studies on...
متن کاملO-GlcNAc signaling attenuates ER stress-induced cardiomyocyte death.
We previously demonstrated that the O-linked beta-N-acetylglucosamine (O-GlcNAc) posttranslational modification confers cardioprotection at least partially through mitochondrial-dependent mechanisms, but it remained unclear if O-GlcNAc signaling interfered with other mechanisms of cell death. Because ischemia/hypoxia causes endoplasmic reticulum (ER) stress, we ascertained whether O-GlcNAc sign...
متن کاملInvolvement of ER stress in retinal cell death
PURPOSE To clarify whether endoplasmic reticulum (ER) stress is involved in retinal cell death, using cultured retinal ganglion cells (RGC-5, a rat ganglion cell line transformed with E1A virus), and transgenic mice ER stress-activated indicator (ERAI) mice carrying a human XBP1 and venus a variant of green fluorescent protein (GFP) fusion gene. METHODS RGC-5 damage was induced by tunicamycin...
