In addition, siCDK8 attenuated cell migration and invasion, increased E‐cadherin expression, and diminished N‐cadherin, Vimentin, and Snail expressions; moreover, the effect of miR‐193a‐5p inhibitor on GC cells was offset in the siCDK8 group (p < 0.01, Figure 9A–G). Here, CDH2 is linked to gastric cancer.
