Cytoscape analysis showed that “focal adhesion” clusters, which includes choline metabolism in cancer (mmu05231), PI3K–Akt signaling pathway (mmu04151), and MAPK signaling pathway (mmu04010) as well as “response to hormone” cluster including pathways in cancer (mmu05200), small-cell lung cancer (mmu05222), and chemokine signaling pathway (mmu04062) had the most tight correlations and were situated in the center of the plots. This evidence concerns the gene AKT1 and cancer.
