WebApr 14, 2024 · Hsp70.1 has a dual function as a chaperone protein and lysosomal stabilizer. In 2009, we reported that calpain-mediated cleavage of carbonylated Hsp70.1 causes neuronal death by inducing lysosomal rupture in the hippocampal CA1 neurons of monkeys after transient brain ischemia. Recently, we also reported that consecutive injections of … WebThere is increasing clinical evidence that phospholipid oxidation products (Ox-PL) play a role in atherosclerosis. This review focuses on the mechanisms by which Ox-PL interact with endothelial cells, monocyte/macrophages, platelets, smooth muscle cells, and HDL to promote atherogenesis.

WebNov 3, 2024 · Enzymatic oxidation or autooxidation of esterified polyunsaturated fatty acids (PUFA) residues within phospholipids in cell membranes or circulating lipoprotein particles leads to the formation of a broad range of oxidized phospholipid (OxPL) species. Webpatients, but the roles of membrane PC composition in the pathogenesis of NASH has not been investigated. Lysophosphatidylcholine acyltransferase 3 (LPCAT3), a phospholipid (PL) remodeling enzyme that produces polyunsaturated PLs, is a major determinant of membrane PC content in the liver. Approach & Results: The expression of LPCAT3 and the …
WebEnergy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation. The key steps of this process, shown in simplified form in the diagram above, include:
WebThe pH decrease of phospholipid-dispersed solutions is mainly induced by oxidation of the phospholipid. The stability against oxidation must be maintained by using highly hydrogenated and unsaturated fatty acids with a low peroxide value (Fig. 31.1).
