CAP1 down-regulation impairs cells migration in hepatocellular carcinoma cells (Liu et al., 2014), in esophageal squamous cell carcinoma (Li et al., 2013), in breast cancer cells (Yu et al., 2014) and in glioma cells (Bao et al., 2016; Fan et al., 2016). This evidence concerns the gene CAP1 and breast carcinoma.
