Background & Aims: Hepatic ischemia‒reperfusion injury (HIRI) is a critical complication of liver surgery and transplantation that contributes significantly to severe organ failure. GRINA, a calcium-regulating endoplasmic reticulum (ER) protein, plays an essential role in controlling the unfolded protein response; however, its role in HIRI remains unclear. The aim of this study was to investigate the function of GRINA in HIRI and explore its potential as a therapeutic target.

Methods This study was a retrospective study to investigate the cardiac effects of liver donation after the transplant operation in a high-volume liver transplant center. Ninety living liver donors were included in the study.

Metabolic requirements of dividing hepatocytes are prerequisite for liver regeneration after injury. In contrast to transcriptional dynamics during liver repair, its metabolic dependencies remain poorly defined. Here, we screened metabolic genes differentially regulated during liver regeneration, and report that SLC13A2, a transporter for TCA cycle intermediates, is decreased in rapid response to partial hepatectomy in mice and recovered along restoration of liver mass and function.

Background: Arsenic trioxide (ATO) is indicated as a broad-spectrum medicine for a variety of diseases, including cancer and cardiac disease. While the role of ATO in hepatic ischemia/reperfusion injury (HIRI) has not been reported. Thus, the purpose of this study was to identify the effects of ATO on HIRI.

During the proliferative phase of liver regeneration, insufficient regulation of hepatocyte hydrogen peroxide (HO) overproduction can result in oxidative stress and hepatocyte death. This study aims to investigate the influence of Aquaporin 5 (Aqp5) on liver regeneration by evaluating its role in reactive oxygen species (ROS) generation and NLRP3-GSDMD-mediated pyroptosis. A 70 % partial hepatectomy (PHx) model was established in Aqp5 mice to evaluate the pathological changes in the liver.
