Title	Alcohol-associated hepatitis induces hepatocyte senescence which is reduced following disease resolution
Description	Background & Aims: Alcohol-associated hepatitis (AH) is an acute form of alcohol-related liver disease (ArLD) with high mortality rate. AH is histologically characterised by cellular processes including steatosis, inflammation and cell death. Apoptosis is the most studied form of cell death in AH; however, the role of cellular senescence, another response to cellular injury, in AH is unknown. Here we aim to explore the mechanisms of ArLD pathophysiology and define the role of senescence in AH. Methods: We performed RNA sequencing and bioinformatics analysis of transjugular liver biopsies (n=65) from AH patients participating in the ISAIAH clinical trial. We also carried out multiomic analysis of an in vitro hepatocyte model of AH. We also performed additional bioinformatics reanalysis of existing AH transcriptomic datasets. Results: Senescence markers and pathways are increasingly expressed in hepatocytes as ArLD progresses towards AH. We find dysregulation of senescence, inflammation and hepatocyte function is reversed at transcriptomic level following AH resolution. We identify dysregulation of two senescence-associated protein complexes, cytochrome c oxidase and the proteasome, which may act as senescence-induction mechanisms. Our in vitro model reveals senescence induction is a direct effect of ethanol on hepatocytes. Conclusions: Our results show a central role for senescence in AH and suggest senolytics as potential therapeutics in early ALD to limit AH severity.
