Independent analysis of Affymetrix gene expression datasets in ovarian cancer tissue (n = 744), ovarian cancer metastases (n = 44), and normal tissue (n = 46) confirmed a significant upregulation of SDC3 in tumor tissue (5.8-fold, p = 1.27 × 10−17) and metastases (3.4-fold, p = 9.43 × 10−7) compared with normal tissue. Here, SDC3 is linked to neoplasm.
