Expression profiles for the CD24 molecule (CD24), SRY (sex determining region Y)-box transcription factor 17 (SOX17), WAP four-disulfide core domain 2 (WFDC2), the epithelial cell adhesion molecule (EPCAM), innate immunity activator (INAVA), and aldehyde oxidase 1 (AOX1) were validated in clinical cancer samples of ovarian cancer, which were among top five dysregulated DEGs revealed by our meta-analysis. This evidence concerns the gene WFDC2 and ovarian cancer.
