Fig. 4. Effect of compounds from S. koreana on PCSK9 and LDLR in the HepG2 human hepatocellular carcinoma cell line. (A) Expression of PCSK9 mRNA was assayed by qRT-PCR in cells treated with compounds (50 μM), and berberine (Ber20, 20 μM) for 24 h. (B) Expression of LDLR mRNA was assayed by qRTPCR in cells treated with compounds (50 μM), and berberine (Ber20, 20 μM) for 24 h.
