To clarify the association between YAP1 and GC, we first collected data from the TCGA (The Cancer Genome Atlas) and GTEx (Genotype‐Tissue Expression) database and compared the YAP1 mRNA expression levels among normal gastric tissues (N = 211) and cancerous gastric tissues (T = 408)26 (Figure 1A). The gene discussed is YAP1; the disease is cancer.
