YAP1 and cancer: TGF-β signaling pathway was upregulated in 23 cancer types, mitotic spindle process in 16 cancer types, Hedgehog signaling pathway in 15 cancer types, KRAS signaling in 8 cancer types, epithelial mesenchymal transition (EMT) in 10 cancer types, and angiogenesis in 7 cancer types, indicating that YAP1 is involved in promoting cell proliferation, cancer cell stemness, invasiveness, and migration processes (Figure 6).
