Life, death, the unfolded protein response and apoptosis.
The unfolded protein response (UPR) occurs in cells in response to accumulation of unfolded proteins in the endoplasmic reticulum (ER).Whenunfolded protein accumulates secondary to a mild stress, universal protein synthesis is inhibited, but then resumes upon recovery. In contrast, a more severe or persistent stress would lead to apoptosis. UPR has not been extensively studied in the heart, tho...
متن کاملIntegration of autophagy, proteasomal degradation, unfolded protein response and apoptosis.
A single cell has the potential to kill an entire human being. Efforts to cure cancer are limited by survival of individual cancer cells despite immune surveillance and toxic therapies. Understanding the intricate network of pathways that maintain cellular homeostasis and mediate stress response or default into cell death is critical to the development of strategies to eradicate cancer. Autopha...
متن کاملThe unfolded protein response
Where does the UPR function? Between the endoplasmic reticulum (ER) and the nucleus of eukaryotic cells. All secreted proteins and proteins that reside in secretory compartments translocate as nascent peptide chains into the ER, where they may undergo folding, modification and assembly before assuming their functional conformations. The ER maintains a specialized oxidizing environment to aid ch...
متن کاملOpposing unfolded-protein-response signals converge on death receptor 5 to control apoptosis.
Protein folding by the endoplasmic reticulum (ER) is physiologically critical; its disruption causes ER stress and augments disease. ER stress activates the unfolded protein response (UPR) to restore homeostasis. If stress persists, the UPR induces apoptotic cell death, but the mechanisms remain elusive. Here, we report that unmitigated ER stress promoted apoptosis through cell-autonomous, UPR-...
متن کاملThe unfolded protein response.
The endoplasmic reticulum (ER) is a principal site for folding and maturation of transmembrane, secretory and ERresident proteins. Perturbations that alter ER homeostasis can lead to accumulation of unfolded proteins (UPs), which is a threat to all living cells. To cope with the stress, cells activate an intracellular signaling pathway – the unfolded protein response (UPR). The UPR is an integr...
