Unfolded protein response and obesity
WebA previous study suggested that IL-6, IL-17, and IFN-γ are closely associated with cell death caused by unfolded protein response (UPR). 17–19 Binding immunoglobulin protein (Bip) is a master regulator of ER homeostasis, which has been determined to inactivate the sensor proteins of UPR and block UPR in the normal state of the cell. WebObesity provides chronic cellular stimuli for the UPR pathway as a result of the stresses and strains placed upon the ER, and without allowing restoration to normal cellular …

Web25 Dec 2014 · Lipid composition could modulate protein folding in, or trafficking through, the ER, indirectly activating UPR transducers by changing the level of unfolded proteins. Changes in the lipid composition could, for example, perturb ER calcium homeostasis, inhibiting the function of calcium-dependent enzymes and chaperones. WebThe unfolded protein response is associated with many diseases, including cancer, metabolic diseases such as type II diabetes and fatty liver diseases, and neurodegenerative diseases, for example, Alzheimer's disease. The UPR is also activated by numerous toxic chemicals and modulates drug action.
Web1 Oct 2011 · Stress induced by accumulation of unfolded proteins at the endoplasmic reticulum (ER) is a classic feature of secretory cells and is observed in many tissues in human diseases including cancer, diabetes, obesity, and neurodegeneration. Cellular adaptation to ER stress is achieved by the activation of the unfolded protein response … Web1 May 2010 · The UPR regulates the expression of genes that encode chaperones—proteins that help other proteins fold properly—and other proteins involved in alleviating ER stress. The UPR is activated...
