The most striking KEGG pathway terms were focal adhesion (n = 12), the Rap1 signaling pathway (n = 11), proteoglycans in cancer (n = 10), microRNAs in cancer (n = 11), the PI3K-Akt signaling pathway (n = 12), the Ras signaling pathway (n = 9) and the ErbB signaling pathway (n = 7) (Figure 5c). This evidence concerns the gene EGFR and cancer.
