Results: The expression levels of Notch1, Snail, MMP-2, N-cadherin and Vimentin in ovarian cancer were high, while the expression levels of E-cadherin were low.Notch1 promoted the expression of Snail, vimentin, N-cadherin and MMP2 protein, but inhibiting the expression of E-cadherin, promoting cell migration and invasion. Here, MMP2 is linked to ovarian cancer.
