miR-378a significantly prevented CRC development in AOM/DSS mice. A Scheme for AOM/DSS-induced colon carcinogenesis in mice. Mice were kept on normal chow. Five-weeks old mice were given AOM, followed by 1% DSS in water for 4 days. At 13 weeks of age, mice were injected with MC-miR378-MM (n = 6, control) or MC-miR378 (n = 6) weekly for 10 weeks. B Diagram of miR-378a mini-circle expression vector (MC-miR378). C Representative photos of CRC tumors in mice treated with MC-miR378 and MC-miR378-MM. Black arrows indicate colon tumors. Both total tumor number and tumors with the size of ≥ 2 mm were reduced in AOM/DSS mice treated with MC-miR378. D H&E staining of colon from two groups of mice. Red arrowhead: acinar regions; green arrowhead: inflammation regions; and blue arrowhead: hyperplasia regions. E, F Scores of hyperplasia, inflammation and adenocarcinoma in AOM/DSS mice treated with MC-miR378 or MC-miR378-MM. Data represent mean ± SEM. **p < 0.01 and ***p < 0.001 (Fig. 6C, E–F: two-tailed student’s t test)
