PREX1 and bladder transitional cell carcinoma: Notably, PREX1 by itself correlated with longer survival in LUAD and KIRC studies (Figure 1A), whereas the PREX1 signaling hub signature had the opposite predictive value, consistent with the result in LGG, and also revealed an increased risk of shorter survival in BLCA, which did not have a significant correlation with PREX1 expression by itself.
