Endoplasmic Reticulum (ER) Stress and Endocrine Disorders
The endoplasmic reticulum (ER) is the organelle where secretory and membrane proteins are synthesized and folded. Unfolded proteins that are retained within the ER can cause ER stress. Eukaryotic cells have a defense system called the "unfolded protein response" (UPR), which protects cells from ER stress. Cells undergo apoptosis when ER stress exceeds the capacity of the UPR, which has been rev...
متن کاملUnfolded proteins and endoplasmic reticulum stress in neurodegenerative disorders
The stimuli for neuronal cell death in neurodegenerative disorders are multi-factorial and may include genetic predisposition, environmental factors, cellular stressors such as oxidative stress and free radical production, bioenergy failure, glutamate-induced excitotoxicity, neuroinflammation, disruption of Ca(2+) -regulating systems, mitochondrial dysfunction and misfolded protein accumulation...
متن کاملEndoplasmic reticulum stress modulates the response of myelinating oligodendrocytes to the immune cytokine interferon-γ
Interferon-gamma (IFN-gamma) is believed to contribute to immune-mediated demyelinating disorders by targeting the myelin-producing oligodendrocyte, a cell known to be highly sensitive to the disruption of protein synthesis and to the perturbation of the secretory pathway. We found that apoptosis induced by IFN-gamma in cultured rat oligodendrocytes was associated with endoplasmic reticulum (ER...
متن کاملEndothelial cells, endoplasmic reticulum stress and oxysterols
Oxysterols are bioactive lipids that act as regulators of lipid metabolism, inflammation, cell viability and are involved in several diseases, including atherosclerosis. Mounting evidence linked the atherosclerosis to endothelium dysfunction; in fact, the endothelium regulates the vascular system with roles in processes such as hemostasis, cell cholesterol, hormone trafficking, signal transduct...
متن کاملEndoplasmic reticulum protein 29 is involved in endoplasmic reticulum stress in islet beta cells.
Endoplasmic reticulum stress (ERS) is correlated with insulin resistance and islet‑cell function. In the present study, the sub‑cellular localization and role of ER protein 29 (Erp29) were investigated in an in vitro ERS model of islet beta cells. The INS‑1 islet cell line was treated with various concentrations of tunicamycin to establish the ERS model. Immunofluorescence microscopy demonstrat...
