Btg2 inhibits Fmo1 UFMylation thus exacerbating ferroptosis and apoptosis in hepatic ischemia-reperfusion injury
Abstract Hepatic ischemia‒reperfusion injury (HIRI) represents a frequently occurring pathological condition during liver surgery, yet the mechanisms governing HIRI remain inadequately comprehended. Here, we investigate the role of B-cell translocation gene 2 (Btg2) in HIRI. Btg2 is upregulated following HIRI. A 70% HIRI model using hepatocyte-specific Btg2 transgenic and systemic Btg2 knockout mice reveals that Btg2 deteriorates hepatic inflammation and apoptosis.

Arginase 1 promotes hepatic lipogenesis by regulating ERK2/PPARγ signaling in a non-canonical manner - Nature Communications
Abstract Obesity and related metabolic disorders, including metabolic dysfunction-associated steatohepatitis (MASLD), have reached epidemic proportions worldwide. We unveil a previously unknown moonlighting role for arginase 1 (Arg1) in facilitating hepatic lipogenesis. Male mice lacking hepatic Arg1 exhibit diminished lipid accumulation in both liver and adipocytes, an effect mirrored in genetically- or diet-induced obesity models following Arg1 inhibitor treatment.
