Moreover, we analyzed the expression of MEX3A in ovarian cancer with different molecular subtypes from TCGA cohort from cBioPortal for cancer genomics(http://www.cbioportal.org/), and the results suggested that MEX3A expression was the highest in the Proliferation subtype, followed by the Mesenchymal type, compared with Fallopian and Immunoreactive subtypes, indicating that MEX3A may be closely related to the proliferation and metastasis of ovarian cancer (Fig. 1E). Here, MEX3A is linked to cancer.
