KRAS and neoplasm: According to GSVA, the MYC signaling, DNA repair, glycolysis, WNT signaling, Hedgehog signaling, mTORC1 signaling, and oxidative phosphorylation pathways were positively related to tumor purity, whereas the KRAS signaling, IL2-STAT5 signaling, inflammatory response, and angiogenesis pathways were negatively related to tumor purity (Figure 7C).
