ADRB2 and obesity due to melanocortin 4 receptor deficiency: Adrb2, Atgl, and Cgi‐58 mRNA levels in iWAT were comparable between chow and HFD fed mice (Figure 7C), raising the possibility that Adrb2, Atgl, and Cgi‐58 proteins are downregulated in obesity by a posttranscriptional mechanism (e.g., m6A methylation).
