To assess the potential clinicopathological relevance of SDC3 expression in ovarian cancer, we analyzed its expression in tumor and control tissues using the online tool TNMplot (https://www.tnmplot.com, accessed on 4 June 2021) [18], which combines public gene expression data on ovarian cancer specimens, ovarian cancer metastases and normal tissue from the GEO, GTEx and TCGA datasets. This evidence concerns the gene SDC3 and ovarian carcinoma.
