Cccp induce mitophagy
WebSeveral studies have indicated that mtROS are not involved in the mitochondrial translocation of PRKN, but Bin Xiao indicated that the stimulation of carbonyl cyanide m-chlorophenylhydrazone (CCCP) is essential for mitophagy. 37 Treatment with CCCP can induce both mitochondrial depolarization and the accumulation of ROS. An objective … WebJul 3, 2014 · Thus, we explored whether Beclin-1 was a possible point of intersection between Bcl-2 proteins and the mitophagy machinery. However, as Figures 3C–3G demonstrate, knockdown of Beclin-1 using two independent small interfering RNAs (siRNAs) failed to attenuate CCCP/Parkin-induced mitophagy. Thus, Parkin-dependent …

WebApr 5, 2024 · AUTAC4 is a mitochondria-targeting AUTAC that promotes mitophagy of small, fragmented mitochondria. Moreover, AUTAC4 can induce K63-linked polyubiquitination. At a concentration of 10 μM, it reduces the loss of mitochondrial membrane potential and apoptosis induced by CCCP treatment. Except for, the … WebJul 7, 2024 · To verify whether mitoNEET inhibition activates CCCP-induced Pink1–Parkin-mediated mitophagy, we examined the expression levels of phosphate AMPKα, Pink1, and Parkin protein in CCCP- treated RAW264.7 cells in the presence or absence of NL-1 (Fig. 2B). We found that NL-1 enhanced the expression levels of phosphate AMPKα, Pink1, …
WebNov 10, 2024 · Furthermore, PSMA7 knockdown and subsequent impairment in PARK2 recruitment led to the repression of mitophagy while assessed through GFP-LC3 and mitochondria (mito-dsRed) colocalization following long term (Fig. 7I and J) otherwise short terminate (Fig. 7K and L) exposure to CCCP-induced mito stress. WebNov 11, 2024 · Mitophagy was induced through mitochondrial depolarisation by treatment with the protonophore CCCP and ubiquitinated MFN proteins were analysed by western …

Recent results illustrated that chelation of mitochondrial iron potently induced mitophagy 11.The role of mitochondria in iron metabolism is well established. The synthesis of iron sulfur cluster (Fe-S) and heme ...
WebMitophagy is a cargo-specific autophagic process that recycles damaged mitochondria to promote mitochondrial turnover. PTEN-induced putative kinase 1 (PINK1) mediates the canonical mitophagic pathway. However, the role of PINK1 in diseases where mitophagy has been purported to play a role, such as colorectal cancer, in unclear.Our results here …
WebMitophagy induced by CCCP affects oocyte meiosis. Considering the critical role of mitochondrial functions in meiosis, we next evaluated whether the abnormal activation of mitophagy affects meiotic progression. GV oocytes from young mice (3–4 W) were first treated with the mitochondrial damage inducer CCCP to determine its effects on meiosis. ... portsmouth 5gWebNov 30, 2024 · In CCCP-induced mitophagy, the ubiquitination of fusion-related proteins mitofusins 1 (MFN-1) and 2 (MFN-2) both depended on PINK1 and Parkin . In rat hippocampal neurons, silencing PINK1 led the mitochondrial fission/fusion dynamics to trend towards fusion, and inhibiting and overexpressing the Parkin gene in hippocampal … optus black friday offerWebJan 13, 2024 · When these cells are shifted from normoxia to hypoxia, mitophagy is induced to decrease mitochondrial quantity, thereby adapting cellular metabolism to anaerobic conditions (Wu & Chen, 2015 ).
