The relative expression levels of miR-378 in CRC tissues and cell lines. (A) The relative expression of miR-378 in CRC tissues (T) and adjacent normal mucosa (N). The bars in the figure indicate the means of the relative expressions of miR-378. (B) The relative expression of miR-378 in CRC cell lines SW620, SW480, HCT116, HT29 and the normal colon epithelium cell line CCD-18Co. **P < 0.01.
