GSVA further confirmed the upregulation of angiogenesis, Hedgehog signaling, Kras signaling, inflammation (including inflammatory response and IL6‐JAK‐STAT3 signaling), Wnt‐β catenin signaling, and protein secretion in tumor‐derived epithelial cells (Figure 2I, Figure S1J). The gene discussed is KRAS; the disease is neoplasm.
