Quantification of gene expression of factors critical for adipocyte differentiation and function (PPARγ2, C/EBPα, C/EBPβ, leptin, adiponectin, and GLUT4) indicated that SIV infection decreased the expression of most of these genes (Fig. 4a), which may increase the risk for fat redistribution, lipoatrophy, or insulin resistance. Here, CEBPA is linked to Insulin resistance.
