WebApr 6, 2024 · The PERK-ATF4-CHOP pathway exerts regulatory effects on the expression of Parkin, a critical regulator in mitochondrial dynamics (Sarrabeth Stone 2015). Parkin plays a role in mitochondrial dynamics 60, 61, bioenergetics 62, 63, and mitophagy 36. Parkin also is known to modulate MAMs, ... WebDec 5, 2013 · Perturbing mitophagy by silencing Parkin led to enhanced apoptotic signaling, suggesting that HBV-induced mitochondrial fission and mitophagy promote cell survival and possibly viral persistence. Altered mitochondrial dynamics associated with HBV infection may contribute to mitochondrial injury and liver disease pathogenesis. Author Summary scratch disk location windows

WebParkin (PRKN) is a ubiquitin E3 ligase that catalyzes the ubiquitination of several proteins. Mutations in the human Parkin gene, PRKN, leads to degeneration of dopaminergic (DA) neurons, resulting in autosomal recessive early-onset parkinsonism and the loss of PRKN function is linked to sporadic Parkinson’s disease (PD).Additionally, several in vitro … WebFeb 6, 2013 · ATF4 silencing exacerbates the toxin-induced reduction of parkin, whereas ATF4 overexpression partially preserves parkin levels. Finally, parkin silencing blocked the protective capacity of ATF4. These results indicate that ATF4 plays a protective role in PD through the regulation of parkin. Introduction WebAug 14, 2024 · In addition, we explored the role of parkin in ATF4-mediated protective effects.
