TRIM31 promotes Atg5/Atg7-independent autophagy in intestinal cells
Autophagy is responsible for the bulk degradation of cytosolic constituents and plays an essential role in the intestinal epithelium by controlling beneficial host-bacterial relationships. Atg5 and Atg7 are thought to be critical for autophagy. However, Atg5- or Atg7-deficient cells still form autophagosomes and autolysosomes, and are capable of removing proteins or bacteria. Here, we report th...
متن کاملBassoon Controls Presynaptic Autophagy through Atg5
Mechanisms regulating the surveillance and clearance of synaptic proteins are not well understood. Intriguingly, the loss of the presynaptic active zone proteins Piccolo and Bassoon triggers the loss of synaptic vesicles (SVs) and compromises synaptic integrity. Here we report that the destruction of SVs in boutons lacking Piccolo and Bassoon was associated with the induction of presynaptic aut...
متن کاملm6A mRNA Methylation: A New Circadian Pacesetter
The purpose of m(6)A methylation of RNA, first observed in the 1970s, has been a longstanding mystery. Fustin et al. now show that it regulates RNA processing and determines the period and oscillatory stability of the mammalian circadian clockwork.
متن کاملMolecular mechanisms and physiological roles of Atg5/Atg7-independent alternative autophagy
ATG5 and ATG7 are considered to be essential molecules for the induction of autophagy. However, we found that cells lacking ATG5 or ATG7 can still form autophagosomes/autolysosomes and perform autophagic protein degradation when subjected to certain types of stress. Although the lipidation of LC3 is accepted as a good indicator of autophagy, this did not occur during ATG5/ATG7-independent alter...
متن کاملMicroRNA-181a inhibits autophagy by targeting Atg5 in hepatocellular carcinoma.
Available evidence suggests that autophagy may serve as a tumor suppressor in cases of chronic liver disease and liver cirrhosis and that autophagic deficiency may lead to hepatocellular carcinoma (HCC). Recent studies suggested that the development of several tumor types could be regulated by microRNA-181a. However, the role of miR-181a in the autophagy of HCC remains unclear. In this study, w...
