IGF2BP3 downregulation decreased the levels of apoptosis and inhibited autophagy induced by A/R challenge in primary cardiomyocytes. These results identified circRNA_101237 as a novel circRNA that regulates cardiomyocyte death and autophagy, and demonstrated that the circRNA‑101237/let‑7a‑5p/IGF2BP3 axis, which serves as a regulator of cardiomyocyte death, may be a potential therapeutic target for the management of cardiovascular diseases.

The autophagy inhibitor 3-MA or silencing ATG7 rescued the apoptosis by knocking down ESR2 via activation of the MAPK signaling pathway in AGS cells, leading to increased apoptosis. In conclusion, these results demonstrated that suppression of ESR2 gene expression could promote GC cell apoptosis, suggesting that it may prove to be a potential therapeutic target for GC.

Journal: Inhibited autophagy impairs systemic nutrient metabolism in Nile tilapia. (Pubmed Central) - Sep 10, 2020 In an 8-week feeding trial, Nile tilapia were fed either a control diet with medium fat and medium carbohydrate (Control), or a control diet supplemented with a classic autophagy inhibitor (chloroquine, CQ)...Physiological status and gene expressions suggested that impaired autophagy might be at least one cause of the metabolic diseases which has been commonly seen in aquaculture. These results indicate that inhibition of autophagy could significantly affect the metabolism of lipid, carbohydrate and protein in fish; hence, autophagy could play important roles in maintaining homeostasis of nutrient metabolism in cultured fish.

In addition, outcomes from the in vivo experiments also showed that oridonin treatment significantly repressed tumorigenic growth of DLD-1 cells without any side effects, which was accompanied by the upregulation of p-AMPK, LC3-II, active caspase-3 protein expression levels and the downregulation of p-mTOR and p-ULK1 protein expression levels. This study demonstrated that oridonin induced apoptosis and autophagy of colon cancer DLD-1 cells via regulating the AMPK/mTOR/ULK1 pathway, which indicated that oridonin may be used as a novel therapeutic intervention for patients with colorectal cancer.

- |||||||||| Journal, BRCA Biomarker: Depletion of NBR1 in urothelial carcinoma cells enhances rapamycin-induced apoptosis through impaired autophagy and mitochondrial dysfunction. (Pubmed Central) - Sep 9, 2020
NBR1-knockdown URCa cells exhibited rather profound mitochondrial dysfunctions in response to rapamycin treatment as evidenced by Δψm collapse, ATP depletion, ROS accumulation, and apoptosis activation. Therefore, our findings provide a rationale for rapamycin treatment of NBR1-knockdown human urothelial cancer through the regulation of autophagy and mitochondrial dysfunction by regulating the AMPK/mTOR signaling pathway, indicating that NBR1 can be a potential therapeutic target of human urothelial cancer.
