Abstract (original English)
Stimulator of interferon response cGAMP interactor 1 (STING1), as an innate immune adaptor protein that mediates DNA sensing, has attracted tremendous biomedical interest. However, several recent researches have revealed the key role of STING1 in regulating the metabolic pathway. Here, we investigated its role in adipocyte differentiation. Preadipocytes with lentivirus-mediated Sting1 knockdown or overexpression were constructed to examine the effect of STING1 on adipocyte differentiation in vitro. Proteomics was performed in adipocytes to explore the mechanisms by which STING1 exerts pro-adipogenesis effects. Coimmunoprecipitation (CoIP)/mass spectrometry (MS) assay were used to identify the interacting partners of STING1. Our results showed that STING1 was upregulated during adipogenic differentiation of 3T3-L1 and white adipose tissue-derived stromal vascular precursor cells (WAT-SVF), accompanied by upregulation of adipocyte marker genes, peroxisome proliferator-activated receptor gamma (Pparg) and CCAAT/enhancer-binding protein beta (Cebpβ). Knockdown or overexpression of Sting1 altered adipogenesis in adipocytes. Mechanistically, proteomics and CoIP/MS assay revealed that STING1 targets non-muscle myosin protein (MYH9) to block its expression, which enhances AKT/GSK3β signaling and mediates β-catenin accumulation, affecting adipogenesis-related genes in adipocytes.
