CCNI2 and colorectal carcinoma: Furthermore, the results of qPCR and WB assays revealed that compared with the human normal colorectal mucosal cells FHC, the mRNA and protein levels of CCNI2 were dramatically increased in CRC cell lines (CACO2, RKO, SW480, and HCT 116), showed in Figure 1C‐D and Figure S2A‐S2B, which was consistent with the results of detection of CCNI2 expression in the tissue microarray of clinical samples.
