When mRNA levels of SNAIL1, E-cadherin, and VIMENTIN were demonstrated to be affected by PARD6A expression, it was indicated that PARD6A likely affects EMT of these ovarian cancer cells through regulating SNAIL1 signaling pathway, thus acting on the downstream E-cadherin and VIMENTIN. The gene discussed is SNAI1; the disease is ovarian carcinoma.
