Fission mitophagy
WebSep 18, 2024 · Mitochondrial fission and mitophagy function as quality control to segregate and degrade immature or damaged mitochondria and to provide materials for mitochondrial biogenesis. Healthy mitochondria tend to fuse together and are believed to function well. The maturation of healthy mitochondria further promotes the maturation of CMs at … WebIndeed, fission is critical for mitophagy. In this process, one depolarized and one hyperpolarized mitochondrion are formed, and only the depolarized mitochondrion is removed, whereas the hyperpolarized mitochondrion can be re-introduced into the mitochondrial network .

WebMar 25, 2024 · This review focuses on only one of the fission genes, FIS1, with the rationale of examining current perspectives and controversies regarding its physiological role in fission-fusion, mitophagy, and apoptosis in relation to human health and disease. The main controversy surrounding Fis1 is what is its primary function in the cell. WebJul 1, 2024 · Similarly, adiponectin attenuated mitophagy and apoptosis induced by H 2 O 2 in C2C12 cells . Interestingly, mitophagy inhibition decreased cell loss during starvation by causing mitochondrial fusion, thereby maintaining ATP production . However, when fission and, therefore, mitophagy were enhanced, starvation increased death .

In this process, one depolarized and one hyperpolarized mitochondrion are formed, and only the depolarized mitochondrion is … WebThe mitochondrial fission initiator protein DRP1 has also been reported to be upregulated in multiple cancers, including, breast, neuroblastoma, pancreatic, colon, and lung cancers. …
WebDec 5, 2013 · Author Summary Hepatitis B virus (HBV) chronic infections represent the common cause for the development of hepatocellular carcinoma. Mitochondrial liver injury has been long recognized as one of the consequences of HBV infection during chronic hepatitis. Mitochondria are dynamic organelles that undergo fission, fusion, and … WebJul 10, 2024 · In addition, fission can segregate damaged segments of mitochondria and facilitate their removal by mitophagy . Inhibition of fission by inactivating DRP1 often prevents mitophagy in various cell types including cardiomyocytes , suggesting a necessary role for fission in mitophagy. However, it is unclear if and how Dox-induced …
WebTH induced the expression of genes regulating mitochondrial fission (Drp1) and mitophagy (Pink1 and Parkin) without altering that of mitochondrial fusion genes (Opa1 and Mfn2) in mouse livers (fig. S4C). In contrast, hepatic expression of these transcripts in XCT790 or TH- and XCT790-treated mice was similar to that in euthyroid mice.
