CTGF is directly targeted by miR-212-3p via the 3′-UTR. (A) Schematic of putative miR-212-3p binding sequences in the 3′-UTR of CTGF, and the generation of CTGF mutants. Relative (B) mRNA and (C) protein expression of CTGF in HCCLM3 or Huh7 cells with or without miR-212-3p were determined. (D) Luciferase assays were used to determine reporter activity in HCCLM3 or Huh7 cells co-transfected with either miR-212-3p mimics or NC, and either pmirGLO-CTGF-WT or pmirGLO-CTGF-MUT. (E) CTGF mRNA expression in the HCC samples was determined by qRT-PCR and (F) negatively correlated with miR-212-3p expression. *P < 0.05; **P < 0.01; ***P < 0.001.
