PECAM1 and hepatocellular carcinoma: Interestingly, a nuclear translocation of MEF2C was also observed in hepatocellular carcinoma, in which the cytosolic location was associated with the proliferation biomarker Ki‐67, while the nuclear location was correlated with the angiogenesis‐associated biomarker CD31, suggesting that the subcellular distribution dictates the overall effect of MEF2C (Bai et al., 2015).
