A further analysis of enriched KEGG pathways (hypergeometric test, Figure 2) also showed a high enrichment of “Cell cycle” (FDR<1e-13, multiple testing correction by Benjamini-Yekutieli method [26]), “Pathways in cancer” (FDR<0.001), “TGF-β signaling pathway” (FDR<0.01), “Focal adhesion” (FDR<0.01), “Oocyte meiosis” (FDR<0.001) and “p53 signaling pathway” (FDR<0.05), which have all been related to breast cancer [27]–[30]. Here, TGFB1 is linked to cancer.
