The results suggested that ECM receptor interaction, calcium signaling pathway, focal adhesion, basal cell carcinoma, Hedgehog signaling pathway, MAPK signaling pathway, TGF-beta signaling pathway, pathway in cancer, cell adhesion molecule, renal cell carcinoma, JAK- STAT signaling pathways, ABC transporter, small cell lung cancer, and Wnt signaling pathways were correlated with the progression of GC. Here, ABCG2 is linked to hereditary clear cell renal cell carcinoma.
