ABSTRACT
Type 2 diabetes mellitus (T2DM) is accompanied by abnormal glucose metabolism and low-grade chronic inflammation. Fibroblast growth factor 21 (FGF-21) is a novel metabolic regulator and can function as an endocrine hormone to regulate glucose and lipid metabolism. Recently, FGF-21 was found to have anti-inflammatory effect, to our knowledge, the effect of FGF-21 on inflammatory state in diabetes has not been elucidated. Here, we use db/db mice as a Type 2 diabetes model to determine whether FGF-21 alleviates inflammatory state while improves hyperglycemia. Our results demonstrated that FGF-21 not only showed potent long lasting hypoglycemic effect, but also demonstrated strong anti-inflammatory effect in the serum and white adipose tissue. Besides, in vitro experiments, insulin resistance (IR) was induced in 3T3-L1 adipocytes by treating with TNF-α. Our results showed that TNF-α impaired glucose metabolism of 3T3-L1 adipocytes but FGF-21 repressed gene expression of inflammatory factors caused by IR and consequently improved the glucose metabolism in 3T3-L1 adipocytes. Furthermore, FGF-21 ameliorated glucose uptake of TNF-α-induced IR in 3T3-L1 adipocytes by inhibiting NF-κB signaling pathway.
