In our integrative pan-cancer analysis, the results showed that overexpression of YAP1 only predicted poor prognosis in PAAD and LGG, which was inconsistent with the reported that YAP overexpression predicted worse OS in LIHC, ESCA, BLCA, and BRCA (Wu et al., 2019). Here, YAP1 is linked to bladder transitional cell carcinoma.
