Objective To research the effect of mir-520c-3p targeted GPC3 to the hepatocellular carcinoma Huh-7 cell proliferation,migration,and the influence of the attack ability and find new theoretical basis for liver hepatocellular carcinoma clinical treatment.Methods The cells were divided into three groups:not transfection of mir-520c-3p group (cell group),negative control group (Nc group),and transfection of mir-520c-3p group (treat ment group).Then used fluorescence quantitative PCR and Western Blot to detect GPC3mRNA gene and protein expression quantity.Cell proliferation of change was detected by the EDU.Made use of Transwell to detect cell invasion and migration ability of the change.Results Fluorescence quantitative PCR results showed that Cell group,NC group and treatment group were 1.13 ± 0.23,1.28 ± 0.15 and 1.05 ± 0.19 (P ＞ 0.05),mir-520-3p could not reduce the GPC3mRNA; but Western Blot detection results showed that GPC3 protein expression level reduce significantly after transfection mir-520c-3p,Cell,NC and treatment group were 2.16 ± 0.08,1.99 ± 0.04 and 0.499 ± 0.05 (P ＜ 0.01).The EDU detection results showed that hepatocellular carcinoma Huh-7 cell proliferation ability obviously inhibited after transfection mir-520c-3p,Cell group,NC group and treatment group were (90.12 ± 1.93) ％,(91.02 ± 0.35) ％ and (77.73 ± 5.88) ％ (P ＜ 0.05),and Transwell test found that hepatocellular carcinoma Huh-7cell invasion abilities were restrained,Cell group,NC group and treatment group were 0.071 ±0.008,0.105 ±0.001 and 0.048 ± 0.002 (P ＜ 0.05),in the same the cells' migration abilities were reduced,Cell group,NC group and treatment group were 0.546 ± 0.010,0.328 ± 0.002 and 0.151 ± 0.002 (P ＜0.01).Conclusions Mir-520c-3p can target GPC3 so that affect hepatocellular carcinoma Huh-7 cell proliferation,invasion and migration abilities. Key words: Mir-520c-3p;  Hepatocellular carcinoma;  GPC3;  Cell proliferation
