Figure 7. Exploring the oncogenic role of ARMC9 in HCC. (A) Validation of the knockdown efficiency of si-ARMC9 in BEL7402 and HCCLM3. (B, C) The effect of ARMC9 knockdown on the proliferation ability of BEL7402 and HCCLM3 cells was evaluated by CCK8 assay. (D, E) The effect of ARMC9 knockdown on the migration and invasion abilities of BEL7402 and HCCLM3 cells was evaluated by Transwell assay.
