CDH1 and neoplasm: Moreover, during getting deeper insight into the effects of potent interaction between DDX17 and Klf4 in HCC cell lines, we discovered that DDX17 could modulate Klf4-dependent target genes at both transcriptional and translational levels containing MMP-2 and E-cadherin, which are eligible for tumor cells to migrate and invade and are directly regulated by Klf416,17.
