PPARG and obesity due to melanocortin 4 receptor deficiency: We also examined the levels of fat-inducing transcript 2 (Fit2), also known as fat storage-inducing transmembrane protein 2 (Fitm2), PPARγ, involved in the microvesicular accumulation of lipid droplets, and Fsp27/Cidec, an important regulator of energy homeostasis, related to the development of metabolic disorders, including obesity, diabetes, and liver steatosis [37].
