Abstract

Type 2 diabetes (T2D) is a common disorder characterized by chronic low‑grade inflammation. In the present study, the expression levels of nuclear receptor subfamily 4 group A member 1 (NR4A1) and the correlation with inflammatory cytokine production and free fatty acids (FFAs) in patients with T2D and healthy participants were investigated. NR4A1 expression levels in peripheral blood mononuclear cells (PBMCs) from patients with T2D (n=30) and healthy controls (n=34) were analyzed. In addition, the levels of fasting blood glucose (FBG), fasting plasma insulin (FIN), FFAs, total cholesterol (TC), triglyceride (TG), high‑density lipoprotein‑cholesterol (HDL‑C) and low‑density lipoprotein‑cholesterol (LDL‑C) were analyzed, and the homeostasis model assessment (HOMA) was used to estimate the insulin resistance (IR). Additionally, PBMCs from healthy subjects were cultured with or without 250 µM palmitic acid (PA). Levels of NR4A1, tumor necrosis factor‑α (TNF‑α) and interleukin‑6 (IL‑6) in the PBMCs were also analyzed. The basal expression levels of NR4A1, TNF‑α and IL‑6 were higher in the T2D patients when compared with the controls. In addition, the levels of FFAs, TG and LDL‑C, as well as the HOMA‑IR, were higher in T2D patients. Furthermore, NR4A1 expression was demonstrated to positively correlate with the HOMA‑IR and the levels of FFAs, TNF‑α, IL‑6, FIN and FBG. Furthermore, 250 µM PA stimulation was shown to increase NR4A1 expression and the secretion of inflammatory cytokines in the cultured PBMCs. Therefore, increased NR4A1 expression levels are correlated with a chronic low‑grade inflammatory state and the disorder of lipid metabolism in patients with T2D.
