Using the GEPIA on line tool (http://gepia.cancer-pku.cn/index.html) to analyze the TCGA ovarian cancer dataset (n = 489 samples), we then confirmed at mRNA level that ITGA6 expression strongly correlated with the one of SP1 (Spearman = 0.56, p 4.6−37 Pearson = 0.4 p 0) and only weakly with the one of c-Myc (Spearman = 0.18, p 2.1−08 Pearson = 0.12 p 0.01) (Figs. 2J and EV2J). This evidence concerns the gene SP1 and ovarian cancer.
