Finally, the four KEGG pathway terms focal adhesion (associated with KGs: FN1, EGFR, and MET), progesterone-mediated oocyte maturation (associated with KGs: CDK1 and AURKA), oocyte meiosis (associated with KGs: CDK1 and AURKA), and adherens junction (associated with KGs: EGFR and MET), were also related to BC progression (Liu B. et al., 2018; Han et al., 2020; Peng et al., 2021; Zeng et al., 2021). The gene discussed is CDK1; the disease is breast cancer.
