The miR-31-3p mimic significantly increased the expression level of miR-31-3p in cervical cancer Caski cells (Fig. 5A) and significantly increased the mRNA and protein levels of E-cadherin, while it downregulated the mRNA and protein levels of Vimentin and Snail (Fig. 5B,C). This evidence concerns the gene SNAI1 and cervical carcinoma.
