Objective:To investigate the effects of apolipoprotein C-Ⅲ gene(ApoC3)silencing by RNA interfering on the lipid contents in HepG2 cells or in the culture medium,and the expression patterns of the genes related to lipid metabolism.Method:Three pairs of small interfering RNA(siRNA)targeting different sequences of ApoC3 mRNA were synthesized and transfected into human hepatoma cell line HepG2 to screen the most effective siRNA.Real-time fluorescence quantitative RCR and enzyme-linked immunosorbent assay detect...
