The aim of the present study was to investigate the protective effect of taurine on lipopolysaccharide (LPS)‑induced liver injury and its mechanisms. Male rats were randomly divided into three groups: Normal saline, LPS model and taurine treatment. Experimental animals were treated with saline or taurine (dissolved in saline, 200 mg/kg/day) via intravenous injection. After 2 h, saline or LPS (0.5 mg/kg) was administrated via intraperitoneal injection. Markers of liver injury, pro‑inflammatory cytokines and superoxide dismutase (SOD) activity were determined in plasma. Liver tissues were removed for morphological analysis and determination by western blot analysis. Taurine significantly reduced the elevation in the levels of LPS‑induced aspartate transaminase and alanine transaminase and decreased the concentrations of LPS‑induced inflammatory factors including tumor necrosis factor‑α and interleukin‑6. Taurine also increased the activity of SOD in serum and the expression of heme oxygenase‑1 protein in liver tissue. Taurine pretreatment also reduced the elevated expression levels of LPS‑induced cyclooxygenase‑2, nuclear factor κB and extracellular regulated protein kinase. The results from the present study demonstrated that taurine alleviates LPS‑induced liver injury. The beneficial role of taurine may be associated with its reduction of pro‑inflammatory response and oxidative stress.

Background: Exposure to ionizing radiation is inevitable due to its extensive use in industrial and medical applications. The search for effective and safe natural therapeutic agents as alternatives to chemical drugs is crucial to mitigate their side effects. This study aimed to evaluate the effects of citicoline as a standalone treatment or in combination with the anti-hepatotoxic drug silymarin in protecting against liver injury caused by γ-radiation in rats.

Ischemia-reperfusion injury (IRI) is a major obstacle in liver transplantation, especially with steatotic donor livers. Dysbiosis of the gut microbiota has been implicated in modulating IRI, and plays a pivotal role in regulating host inflammatory and immune responses, but its specific role in liver transplantation IRI remains unclear. This study explores whether can mitigate IRI and its underlying mechanisms.

Background: Cocaine intoxication and abuse is a worldwide problem that can be the cause of numerous acute medical complications, including severe acute hepatitis. Although these cases are scarce, they are extremely serious and may lead to liver transplantation or death. Management of toxic hepatitis, once the causative agent has been discontinued, is essentially symptomatic, based on clinical and biological monitoring and prevention of complications related to acute hepatitis.

Remote ischemic conditioning (RIC), including pre-conditioning (RIPC, before the ischemic event), per-conditioning (RIPerC, during the ischemic event), and post-conditioning (RIPostC, after the ischemic event), protects the liver in animal hepatic ischemia-reperfusion injuries models. However, several questions regarding the optimal timing of intervention and administration protocols remain unanswered. Therefore, the preclinical evidence on RIC in the HIRI models was systematically reviewed and meta-analyzed in the present review to provide constructive and helpful information for future works.
