CDK6 and hepatocellular carcinoma: The mRNA expression (Figure 5F) and protein level (Figure S2B,C, Supporting Information) of CDK6 in the IGF2BP2 lentiviral transfected cell lines of MDA‐MB‐231 and HCC‐1806 showed a positive correlation between IGF2BP2 and CDK6 at the protein level, but not on the transcriptional level.
