Abstract

Alcohol dehydrogenase 1 (ADH1) is an alcohol-oxidizing Enzyme with poorlydefined biology. Here we report that ADH1 is highly expressed in kidneys of mice with lethal endotoxemia and is transcriptionally upregulated in tubular cells by lipopolysaccharide (LPS) stimuli through TLR4/NF-κB cascade. The Adh1 knockout (Adh1KO) mice with lethal endotoxemia displayed increased susceptibility to acute kidney injury (AKI) but not systemic inflammatory response. Adh1KO mice develop more severe tubular cell Apoptosis in comparison to Adh1 wild-type (Adh1WT) mice during course of lethal endotoxemia. ADH1 deficiency facilitates the LPS-induced tubular cell Apoptosis in a caspase-dependent manner. Mechanistically, ADH1 deficiency dampens tubular Mitophagy that relies on PINK1-Parkin pathway characterized by the reduced membrane potential, Reactive Oxygen Species (ROS) and release of fragmented mtDNA to cytosol. Kidney-specific overexpression of PINK1 and Parkin by adeno-associated viral vector 9 (AAV9) delivery ameliorates AKI exacerbation in Adh1KO mice with lethal endotoxemia. Our study supports the notion that ADH1 is critical for blockade of tubular Apoptosis mediated by Mitophagy, allowing the rapid identification and targeting of alcohol-metabolic route applicable to septic AKI.
