The Rspo-Lgr4/5-Znrf3/Rnf43 module is a master regulator of hepatic Wnt/β-catenin signaling and metabolic zonation, but its impact on nonalcoholic fatty liver disease (NAFLD) remains unclear. We studied whether hepatic epithelial cell-specific loss of the Wnt/β-catenin modulators Leucine-Rich Repeat-Containing G Protein-Coupled Receptor 4/5 (Lgr4/5) promoted NAFLD. Three and 6 months-old mice with hepatic epithelial cell-specific deletion of both receptors Lgr4/5 (Lgr4/5dLKO) were compared to control mice upon feeding with normal diet (ND) or high fat diet (HFD)...
