Our colony formation assays, cell growth curve, and cell viability assay demonstrated that forced H19 expression in the two cell lines promoted cell proliferation in both cell lines compared with the control treatment (Figures 1(b), 1(c), 1(d), 1(h), 1(i), 1(j), and 1(k), P < 0.05), whereas H19 knockdown significantly suppressed CRC cell proliferation in both cell lines compared with the control treatment (Figures 1(e), 1(f), 1(g), 1(l), 1(m), 1(n), and 1(o), P < 0.05). Here, H19 is linked to colorectal carcinoma.
