Obesity induces a profound metabolic rewiring in EAT, with downregulation of genes associated with glucose metabolism (e.g., SLC24A, CS, GPT, OGDH, ACO2, GPI, LDHD) and lipid metabolism (e.g., GYS2, GPAT3, CRAT, FASN, ACADVL, DGAT1, DGAT2, NAT8L, SCD) as well as changes in genes related to adipogenesis (HES1, MXD3, NR4A2, RGS2, PPP1R15B, ADAMTS1, CEBPD, KDM7A). The gene discussed is PPP1R15B; the disease is obesity due to melanocortin 4 receptor deficiency.
