Summary: The study shows that Cycloastragenol (CAG) attenuates airway inflammation in an ovalbumin-induced mouse asthma model by suppressing leukocytes, eosinophils, inflammatory cytokines, and inflammatory cell infiltration. Additionally, molecular docking simulations suggest that CAG inhibits autophagy pathways in lung cells, contributing to its anti-inflammatory effects in asthma.

Summary: Myocardial infarction (MI) is lethal due to acute ischemia and hypoxia, leading to cardiac tissue apoptosis. In this study, we investigated the role of sonodynamic therapy (SDT) in reducing MI-induced cardiomyocyte apoptosis by activating the autophagy pathway. Our results show that SDT improves cardiac function and reduces MI-induced cardiomyocyte apoptosis by enhancing autophagy. Furthermore, we found that the protective effect of SDT is mediated by the activation of MHRT-mediated autophagy. Therefore, SDT may be a potential method for the treatment of post-myocardial infarction heart failure.

Summary: The study aims to investigate the role of GRK4 in the pathogenesis and progression of myocardial infarction (MI). Results showed that GRK4 expression was increased in the heart after MI, and overexpression of GRK4 aggravated cardiac infarction and dysfunction while specific gene knockout ameliorated these effects. GRK4 inhibited autophagy and promoted cardiomyocyte apoptosis, effects mediated by HDAC4 phosphorylation and a decrease in beclin-1 expression, leading to greater impairment of cardiac function in MI patients carrying the GRK4 A486V variant.

Summary: The authors provide evidence that FYCO1, a component of the autophagic machinery, is essential for adaptation to cardiac stress. Lack of FYCO1 affects autophagy induction after glucose deprivation, leading to impaired cardiac function. FYCO1 overexpression rescues cardiac dysfunction in response to biomechanical stress by inducing autophagy.

Summary: Cardiac remodeling and contractile dysfunction are major causes of hypertrophy-associated heart failure, characterized by accumulation of modified proteins due to impaired autophagy-lysosomal pathway in aged and diseased hearts. Autophagy inducer rapamycin has cardioprotective effects by improving cardiomyocyte autophagy and contractility. Endothelin 1 (ET-1) decreases autophagy and cardiomyocyte contractility, similar to siAtg5-treated cells and TAC-mice, highlighting the crucial role of autophagy in cardiomyocyte contractility and cardiac performance.

Summary: This study reports that autophagy-related gene 7 (ATG7) regulates cell cycle and survival during metabolic stress by modulating the phosphorylation and ubiquitination of PDCD4. ATG7 senses the decrease of ATP levels to suppress AKT-mediated PDCD4 phosphorylation, thereby reducing apoptosis and promoting cell survival during stress periods.

Summary: This study verifies that gga-miR-146b-3p attenuates proliferation and autophagy but promotes apoptosis in chicken granulosa cells (GC) by targeting AKT1 through the PI3K/AKT signaling pathway. These findings provide important insights into the molecular regulation of granulosa cell function during folliculogenesis.

Summary: Ischemic stroke is a common and serious disease, and neuroinflammation plays a crucial role in its progression. Microglia, astrocytes, and infiltrating immune cells are involved in the complicated neuroinflammation cascade, releasing different molecules that affect inflammation. Flavonoids, plant-specific compounds, have shown protective effects against cerebral ischemia injury by modulating the inflammatory responses.
