Interaction between COL1A2 and miR-29a-3p. a Putative target sequence of miR-29a-3p on the 3′-UTR of COL1A2. b The activity of luciferase was detected by luciferase reporter gene assay. c COL1A2 mRNA expression level in BSG823 cells. d–f COL1A2 protein expression level in BSG823 cells. g COL1A2 expression levels in GC cell lines. h COL1A2 relative expression levels in GC tissues and adjacent normal tissues (n = 42). *p < 0.05, **p < 0.01, ***p < 0.001, n = 3
