WebIt is possible that Drp1 promotes mitochondrial fission, which contributes to “regenerating” functional competent mitochondria through redistribution of mitochondrial DNA, RNA, and proteins . OXPHOS complex assembly could be improved by a “rejuvenated” population of mitochondria in the Pink1-KO/Drp1. Alternatively, Drp1 could achieve ... WebIn DSS mice, levels of ulceration were greater in IEC-TFAM -/- mice (25%) compared to WT (7.5%) (P<0.005). More importantly, levels of crypt fissioning were 85% lower in TFAM-deficient (GFP+) compared to WT …

WebThe failure of ulcers healing is a characteristic feature of IBD. Mitochondrial dysfunction in intestinal epithelial cells (IEC) occurs in IBD and is linked to worse clinical outcomes in pediatric Crohn’s and ulcerative colitis … Next, we sought to understand how mitochondrial fission drives HSC activation. Given that mitochondrial dynamics regulate energy metabolism [26, 27], we speculated that mitochondrial fission regulates OxPhos during HSC activation. As expected, OxPhos was promoted in active HSCs with increased basal and maximal … See more To confirm whether mitochondrial fission is clinically relevant to liver fibrosis, we first assessed the expression of key proteins mediating … See more It is well-established that inducing apoptosis of active HSCs is an effective strategy for attenuating liver fibrosis [1, 24, 25]. Hence, we … See more To clarify the role of increased mitochondrial fission in HSC activation, fis1 was first overexpressed to enhance mitochondrial fission without TGF-β1 treatment. Overexpression of Fis1 was confirmed by qRT … See more Finally, we sought to determine the cause of mitochondrial dynamics imbalance.

WebNov 25, 2016 · Mitochondrial damage in fission yeast led to repression of genes encoding OXPHOS complex proteins, except for complex 2 (succinate dehydrogenase) that also participates in the TCA cycle and may be required to maintain TCA activity (Fig. 8). The TCA cycle could also be required during rapid growth, even when ATP production by … WebOct 15, 2024 · The increased OXPHOS leads to elevated LDLR levels, which provides a possible explanation for the reduced plasma cholesterol levels in PFIC1 disease. ATP8B1 is a phospholipid flippase that is deficient in patients with progressive familial intrahepatic cholestasis type 1 (PFIC1).
WebMar 18, 2024 · A change in the metabolic flux of glucose from mitochondrial oxidative phosphorylation (OXPHOS) to aerobic glycolysis is regarded as one hallmark of cancer. However, the mechanisms underlying the metabolic switch between aerobic glycolysis and OXPHOS are unclear. Here we show that the M2 isoform of pyruvate kinase (PKM2), …
