The mir-19a and miR-19b expression levels tripled their values in the obese subjects compared to the control group (Figure 6A,B), and the PPARG expression decreased by almost 25% in the obese patients, as shown in Figure 6C. In order to verify whether the expression levels of these miRs are fully or partially restored after weight loss, the expression levels of miR-19a, miR-19b and PPARG were analyzed in six patients with morbid obesity and in the same patients after body weight normalization induced by bariatric surgery. Here, PPARG is linked to morbid obesity.
