The results of Western blotting and qPCR showed that the overexpression of the miR-548x-3p mimic decreased the protein expression and mRNA expression of CCNA2 in the CRC cells; reversely, the overexpression of the miR-548x-3p inhibitor increased the protein expression and mRNA expression of CCNA2 in the CRC cells (Fig. 5, C and D). Here, CCNA2 is linked to colorectal carcinoma.
