The pathways related to breast cancer obtained from literature were as follows: apoptosis pathway, breast tumor kinase pathway, cyclin-dependent kinases pathway, estrogen signaling pathway, hedgehog signaling pathway, human epidermal growth factor receptor 2 (HER2) signaling pathway, mammalian target of rapamycin signaling pathway, notch signaling pathway, phosphoinositide 3-kinases (PI3K)- protein kinase B (Akt) signaling pathway, and Wingless and INT-1 (Wnt)/β-catenin signaling pathway [49,50]. The gene discussed is PTK6; the disease is breast cancer.
