Ischemic stroke is a leading cause of death and disability worldwide, and autophagy may be involved in the pathological process of cerebral ischemia/reperfusion injury. Hydrogen sulfide (H2S) is an endogenous gasotransmitter with protective effects against multiple diseases. Here, we tested the effect of H2S on cerebral ischemia/reperfusion injury in rats. Sodium hydrosulfide (NaHS), an H2S don...

The pathogenesis of non-alcoholic steatohepatitis (NASH) is still unclear and the prevention of the development of hepatocellular carcinoma (HCC) has not been established. We established an atherogenic and high-fat diet mouse model that develops hepatic steatosis, inflammation, fibrosis, and liver tumors at a high frequency. Using two NASH-HCC mouse models, we showed that peretinoin, an acyclic...

The liver, the largest organ with multiple synthesis and secretion functions in mammals, consists of hepatocytes and Kupffer, stem, endothelial, stellate and other parenchymal cells. Because of early and extensive contact with the external environment, hepatic ischaemia reperfusion (IR) may result in mitochondrial dysfunction, autophagy and apoptosis of cells and tissues under various pathologi...

introduction drug-induced liver injury is a frequent cause of hepatic dysfunction. several drugs have been identified to cause autoimmune hepatitis (aih). environmental chemicals are capable of triggering a certain degree of liver injury. however, toxin induced aih is rare. conclusions chronic (long-term) exposures to dichlorvos can lead to aih. a detailed inquiry of medical history and liver b...

conclusions in conclusion, we have shown that vitamin c administration provides protection against csa-induced injury in rat liver function and may have hepatoprotective role in the patients experiencing csa treatment. background cyclosporine a (csa) is an important immunosuppressive agent; however, its clinical use is limited by several side effects such as hepatotoxicity. vitamin c (ascorbic ...

The pathogenesis of renal impairment in chronic liver diseases (CLDs) has been primarily studied in the advanced stages of hepatic injury. Meanwhile, the pathology of renal impairment in the early phase of CLDs is poorly understood, and animal models to elucidate its mechanisms are needed. Thus, we investigated whether an existing mouse model of CLD induced by 3,5-diethoxycarbonyl-1,4-dihydroco...

This study was undertaken to elucidate whether and how autophagy was regulated in aldosterone (Aldo)-induced podocyte injury and to examine its role in this model both in vitro and in vivo. In cultured podocytes, Aldo increased autophagy flux as indicated by the enhanced expression of LC3-II/LC3-I and the reduction of p62. Autophagy induction with rapamycin (RP) provided a cytoprotective effect...

Remodeling of cytoskeleton structures, such as microtubule assembly, is believed to be crucial for growth cone initiation and regrowth of injured axons. Autophagy plays important roles in maintaining cellular homoeostasis, and its dysfunction causes neuronal degeneration. The role of autophagy in axon regeneration after injury remains speculative. Here we demonstrate a role of autophagy in regu...

conclusions hepatotoxicity of halogenated inhalational anesthetics has been well documented in available literature. halothane-induced liver injury was extensively acknowledged; however, the next generation halogenated anesthetics have different molecular structures and associated with less hepatotoxicity. although anesthesia-induced hepatitis is not a common occurrence, we must consider the as...

Electroacupuncture (EA) pretreatment has been reported to induce tolerance against cerebral ischemia/reperfusion (I/R) injury; however, the mechanisms underlying the beneficial effects of EA remain to be elucidated. Increasing evidence has suggested that excess activation of autophagy is important in I/R injury. The present study aimed to investigate the hypothesis that EA pretreatment‑induced ...
