摘要

Adipogenesis is the healthy expansion of white adipose tissue (WAT), serving as a compensatory response to maintain metabolic homeostasis in the presence of excess energy in the body. Therefore, the identification of novel regulatory molecules in adipogenesis, specifically membrane receptors such as G protein-coupled receptors (GPCRs), holds significant clinical promise. These receptors can serve as viable targets for pharmaceuticals, offering potential for restoring metabolic homeostasis in individuals with obesity. We utilized trajectory inference methods to analyze three distinct single-nucleus sequencing (sNuc-seq) datasets of adipose tissue and systematically identified GPCRs with the potential to regulate adipogenesis. Through verification in primary adipose progenitor cells (APCs) of mice, we discovered that ADGRD1 promoted the differentiation of APCs, while GPR39 inhibits this process. In the obese mouse model induced by a high-fat diet (HFD), both gain-of-function and loss-of-function studies validated that ADGRD1 promoted adipogenesis, thereby improving metabolic homeostasis, while GPR39 inhibited adipogenesis, leading to metabolic dysfunction. Additionally, through the analysis of 2,400 ChIP-seq data and 1,204 bulk RNA-seq data, we found that the transcription factors (TFs) MEF2D and TCF12 regulated the expression of ADGRD1 and GPR39, respectively. Our study revealed the regulatory role of GPCRs in adipogenesis, providing novel targets for clinical intervention of metabolic dysfunction in obese patients.
