ADGRG6 promotes adipogenesis and is involved in sex-specific fat distribution
Fat distribution differences between males and females are a major risk factor for metabolic disease, but their genetic etiology remains largely unknown. Here, we establish ADGRG6 as a major factor in adipogenesis and gender fat distribution. Deletion of ADGRG6 in human adipocytes impairs adipogenesis due to reduced cAMP signaling. Conditionally knocking out Adgrg6 in mouse adipocytes or deleting an intronic enhancer associated with gender fat distribution generates males with female-like fat deposition, which are protected against high-fat-diet-induced obesity and have improved insulin response. To showcase its therapeutic potential, we demonstrate that CRISPRi targeting of the Adgrg6 promoter or enhancer prevents high-fat-diet-induced obesity. Combined, our results associate ADGRG6 as a gender fat distribution gene and highlight its potential as a therapeutic target for metabolic disease.
