Journal: Ononin alleviates HO-induced cardiomyocyte apoptosis and improves cardiac function by activating the AMPK/mTOR/autophagy pathway. (Pubmed Central) - Sep 30, 2021 However, these anti-apoptotic effects mediated by ON were lost after autophagy inhibition by chloroquine or AMPK inhibition by Compound C. Finally, the protective effects of ON on cardiomyocytes in vitro could also be observed in vivo...Using echocardiography and Masson's staining, ON was shown to increase the ejection fraction and decrease cardiac fibrosis in rats with myocardial infarction. These results suggest that ON exerts cardioprotective effects by improving autophagy via the AMPK/mTOR signaling pathway.

Journal: Autophagy inhibition blunts PDGFRA adipose progenitors' cell-autonomous fibrogenic response to high-fat diet. (Pubmed Central) - Sep 30, 2021 We found that autophagy inhibition promotes global cell-autonomous remodeling of the paracrine TGF-BMP family landscape, whereas ECM gene modulation was independent of the autophagic regulation of GTF2IRD1. The progenitor-specific mouse model of ATG7 inhibition confirms the requirement of autophagy for white/beige adipocyte turnover, and combined to in vitro experiments, reveal progenitor autophagy dependence for AT fibrogenic response to HFD, through the paracrine remodeling of TGF-BMP factors balance.Abbreviations: CQ: chloroquine; ECM: extracellular matrix; EpiAT: epididymal adipose tissue; GTF2IRD1: general transcription factor II I repeat domain-containing 1; HFD: high-fat diet; KO: knockout; OvAT: ovarian adipose tissue; PDGFR: platelet derived growth factor receptor; ScAT: subcutaneous adipose tissue; TGF-BMP: transforming growth factor-bone morphogenic protein.

Intracellular microtubule-associated protein 1A/1B-light chain 3 (LC3) levels were increased in poly(I:C)-treated cells; however, they were decreased in cells pretreated with 3-methyladenine (3-MA)-a commonly used inhibitor of autophagy. These results suggest that poly(I:C) induces autophagy and enhances ROS production via MEK1/2-mediated signaling to suppress intracellular bacterial growth in S. Typhimurium-infected murine macrophages, and that a TLR3 agonist could be developed as an immune enhancer to protect against S. Typhimurium infection.

[VIRTUAL] STAT3 Inhibitor JSI-124 Induces Autophagic Cell Death in RN5 Murine Mesothelioma Cells () - Sep 26, 2021 - Abstract #IMIG2021IMIG_53; RN5 cells were pretreated with 3-methyladenine (2.5 mM) or chloroquine (50 µM) for 1h, and then coincubation with JSI-124 for another 24 h. Levels of protein expression were analyzed by western blot using antibodies against caspase 3, PARP, MAP1LC3B-II, p-mTOR/p-p70S6K and p-JAK2/p-STAT3. STAT3 inhibitor JSI-124 induces protective autophagy in RN5 murine mesothelioma cells through mTOR/p70S6K signaling pathway, suggesting that JSI-124 may be a potential therapeutic strategy for MPM.
