OVOL1 and breast cancer: Since it is pivotal for epithelial cells to acquire the EMP ability to initiate the invasion–metastasis cascade,4 we examined the possible association between OVOL1 expression and an established set of EMT genes in breast cancer patients.38 Breast cancer patients with a higher EMT score were considered as more mesenchymal-like, while those with a lower EMT score were considered as more epithelial-like.
