The effect on regulating cholesterol disorders and mechanism of quercetin on the HepG2 cells induced by LDL for 24 h. a-c Expression of SREBP2 and HMGCR protein were analyzed by western blotting. d Expression of SREBP2 and HMGCR protein were analyzed by immunofluorescence assay. Control: control group; LDL: a high cholesterol level simulation model of HepG2 cells by low density lipoprotein (25 μg ml− 1); LDL + Que.: quercetin with LDL model HepG2 cells (30, 10 μmol l− 1). Data were presented as mean ± SEM. n = 6, *p < 0.05, **p < 0.01, ***p < 0.001 vs. control group
