Fig. 5. Effect of compound 15 on PCSK9 and LDLR in the HepG2 human hepatocellular carcinoma cell line. (A) Expression of PCSK9 was assayed by qRTPCR in cells treated with compound 15 (2, 10 and 50 μM), and berberine (Ber10, 10 μM) for 24 h. (B) Expression of PCSK9 and LDLR were assayed by western blot in cells treated with compound 15 (10, 40 and 50 μM), and berberine (Ber20, 20 μM) for 24 h *p <0.05.
