The functionality of miR-212-3p in HCC CTGF was validated through assaying Huh7miR-212-3p and HCCLM3miR-212-3p cells transfected with CTGF overexpression plasmids (Huh7miR-212-3p+CTGF and HCCLM3miR-212-3p+CTGF), and the efficacy of the intervention was evaluated via western blot and qRT-PCR (Fig. 5A,B). Here, CCN2 is linked to hepatocellular carcinoma.
