Immunohistochemical detection of SREBP-2, Pcsk9 and LDL-R expression in the liver tissue. Tissue from the CON, HLP and TAN groups was collected and stained with antibodies against SREBP-2, Pcsk9 and LDL-R. (A) SREBP-2 protein expression in liver tissue. (B) Pcsk9 protein expression in liver tissue. Data are presented as the mean ± standard deviation. **P<0.01. SREBP-2, sterol regulatory element-binding protein 2; Pcsk9, proprotein convertase subtilisin/kexin type 9; LDL-R, low-density lipoprotein receptor; CON, control; HLP, high lipid diet-fed rats; TAN, Tanshinone IIA treatment of high lipid diet-fed rats; IOD, integrated optical density. (C) LDL-R protein expression in liver tissue. Data are presented as the mean ± standard deviation. **P<0.01. LDL-R, low-density lipoprotein receptor; CON, control; HLP, high lipid diet-fed rats; TAN, Tanshinone IIA treatment of high lipid diet-fed rats; IOD, integrated optical density.
