Chronic stressors flatten diurnal glucocorticoid oscillations, resulting in obesity, insulin resistance, and diabetes. How such flattened diurnal glucocorticoid oscillations increase fat storage is unknown. Here we investigated the consequences in mice and found that flattening of glucocorticoid oscillations results not only in body weight gain, mainly due to increases in white fat depot mass, but also leads to hyperinsulinemia and fat accumulation in brown adipose tissue. A transcriptomic analysis of white and brown adipose tissues revealed that flattened glucocorticoid oscillations cause dysregulated lipid metabolism with a prominent role of the fatty acid transporter Cd36 and insulin-driven adipocyte hypertrophy. Indeed, Cd36 knockout mice are partially protected against the adverse effects of flattened GC oscillations including body weight gain and lipid accumulation in the brown and visceral white fat depots. These results show the molecular mechanisms how flattened glucocorticoid oscillations can cause obesity and diabetes.
