Aim To investigate the effect of high glucose on regulating the expression of CD36 and lipid accumu- lation in THP-1 macrophages. Methods THP-1 macrophages were incubated with different concentrations of D-glu- cose (5.6, 11, 20, 30 and 35 mmol/L), 50 mg/L oxidized low density lipoprotein (ox-LDL), 50 mg/L ox-LDL + 20 mmol/L D-glucose for 24 h. Total cholesterol content in THP-1 macrophages was determined by high performance liquid chromatography, the lipid accumulation was detected by oil red O stain. CD36 mRNA and protein levels were det...
