Our analysis demonstrated that elevated OLR1 expression was closely associated with poor PFI in ACC, COAD, GBM, HNSCC, LGG, LUSC, PAAD, and PRAD; however, in BLCA, CHOL, DLBC, and SKCM, a high OLR1 expression level represented a better PFI outcome (Figure S1A). The gene discussed is OLR1; the disease is bladder transitional cell carcinoma.
