Abstract
Nonalcoholic steatohepatitis (NASH) is an advanced form of fatty liver disease with complex pathogenic mechanisms. Here, the authors report that SRSF1 deficiency in mice livers provokes deleterious R-loop formation and genotoxicity, which impedes hepatocellular gene expression, metabolism, and lipid trafficking, resulting in NASH-like pathology.
