Compared with the LPS group, VK2 improved histopathological changes; alleviated inflammation, apoptosis, and TJ injury; increased antioxidant enzyme activity; reduced Ca2+ overload; regulated mitochondrial function; and inhibited lung autophagy. These results indicate that VK2 could improve tight junction protein loss, inflammation, and cell apoptosis in LPS-induced ALI by inhibiting the mitochondrial dysfunction and excessive autophagy, indicating that VK2 plays a beneficial role in ALI and might be a potential therapeutic strategy.

Journal: Subversion of selective autophagy for the biogenesis of tombusvirus replication organelles inhibits autophagy. (Pubmed Central) - Mar 27, 2024 In addition, we observed that several core autophagy proteins, such as ATG1a, ATG4, ATG5, ATG101 and the plant-specific SH3P2 autophagy adaptor proteins were also re-localized to TBSV VROs, suggesting that TBSV hijacks the autophagy machinery in plant cells...We propose that the VRO-associated condensates trap those autophagy proteins, taking them away from the autophagy pathway. Overall, tombusviruses hijack selective autophagy to provide phospholipid-rich membranes for replication and to regulate the antiviral autophagic flux.

We show that exposure to white light at a dose of 3.6 J/cm2 induces an alteration of the global cellular structure, DNA damage and an activation of cellular stress pathways. The exposure to blue light triggers DNA damage and the activation of autophagy, while exposure to red light modulates the inflammatory response and inhibits autophagy.

Inhibiting autophagy reduced the phagocytosis of bacteria, in cells with gelatin-coating, while stimulating autophagy enhanced phagocytosis. This study finds the bacteria-phagocytosis stimulatory effect of gelatin in PMA-treated U937 cells and reveals the positive regulatory role of autophagy, predicting the potential use of gelatin products in anti-bacterial therapy.

SPAUTIN-1 alleviated LPS-induced inflammatory injury by inhibiting the NF-?B pathway in leukocytes and protected epithelial cells from oxidative damage, positioning it as a potential therapeutic candidate for ALI.

Journal: DMC triggers MDA-MB-231 cells apoptosis via inhibiting protective autophagy and PI3K/AKT/mTOR pathway by enhancing ROS level. (Pubmed Central) - Mar 23, 2024 Moreover, the phosphorylation levels of phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), and its mechanistic target of rapamycin kinase (mTOR) were also decreased after 30??M DMC incubating for 24?h...The inhibition of autophagy flow and PI3K/AKT/mTOR pathway could be reversed after being treated with ROS scavenger NAC. Altogether, the results of the present study suggest that DMC effectively induces apoptosis and growth inhibition in MDA-MB-231 cells through blocking autophagy flow and regulating the PI3K/AKT/mTOR pathway by increasing ROS level.

Journal: Calebin A modulates inflammatory and autophagy signals for the prevention and treatment of osteoarthritis. (Pubmed Central) - Mar 23, 2024 To study the anti-degradative and anti-apoptotic effects of CA in an inflamed joint, an in vitro model of OA-EN was created and treated with antisense oligonucleotides targeting NF-?B (ASO-NF-?B), and I?B kinase (IKK) inhibitor (BMS-345541) or the autophagy inhibitor 3-methyladenine (3-MA) and/or CA to affect chondrocyte proliferation, degradation, apoptosis, and autophagy...However, the preventive properties of CA in OA-EN could be partially abrogated by the autophagy inhibitor 3-MA. The present results reveal for the first time that CA is able to ameliorate the progression of OA by modulating autophagy pathway, inhibiting inflammation and apoptosis in chondrocytes, suggesting that CA may be a novel therapeutic compound for OA.

Collectively, our findings strongly suggest that p120 plays a pivotal role in fostering autophagy while concurrently hindering apoptosis in macrophages, achieved through modulation of the mTOR/ULK-1 signaling pathway in sepsis. This underscores the potential of targeting macrophage p120 as an innovative therapeutic avenue for treating inflammatory disorders.

Journal: MALT-1 shortens lifespan by inhibiting autophagy in the intestine of C. elegans. (Pubmed Central) - Mar 21, 2024 Silencing of the autophagy regulators ATG-13, BEC-1 or LGG-2, but not the TOR homolog LET-363, reversed lifespan extension caused by MALT-1 deficiency. These findings suggest that MALT-1 limits the lifespan of C. elegans by acting as an inhibitor of an early step of autophagy in the intestine.

Journal, PD(L)-1 Biomarker, IO biomarker: USP24-i-101 targeting of USP24 activates autophagy to inhibit drug resistance acquired during cancer therapy. (Pubmed Central) - Mar 16, 2024 In addition, inhibition of autophagy by bafilomycin-A1 significantly abolished the effect of USP24-i-101 on maintaining genomic integrity, decreasing PD-L1 and inhibiting drug resistance acquired in chemotherapy or targeted therapy. In summary, an increase in the expression of USP24 in cancer cells is beneficial for the induction of drug resistance and targeting USP24 by USP24-i-101 optimized from USP24-i inhibits drug resistance acquired during cancer therapy by increasing PD-L1 protein degradation and genomic stability in an autophagy induction-dependent manner.

Higher plasma ACBP levels in PLWH on ART were associated with inflammation, unfit metabolism, and markers of T-cell dysfunction. Our findings indicate that circulating ACBP directly abates autophagy and anti-HIV T-cell functions, compelling the development of circulating ACBP inhibitors aiming at improving anti-HIV T-cell responses in PLWH, towards an HIV cure.

Journal: The interlacing anticancer effect of pharmacologic ascorbate, chloroquine, and resveratrol. (Pubmed Central) - Mar 15, 2024 It seems resveratrol-induced cytotoxicity is independent of reactive oxygen species (ROS) generation and accompanied by a significant elevation of caspase-3/7 activity, while pharmacologic ascorbate-induced cytotoxicity shows strong ROS dependence but proved to be caspase-independent. Our results are particularly important since ascorbate and resveratrol are natural compounds without significant harmful effects on normal cells, and chloroquine is a known antimalarial drug that can easily be repurposed.
