Then, we utilized clinical information from the TCGA database to evaluate the prognostic value of COL10A1 in BLCA and found that high expression of COL10A1 was significantly correlated with OS prognosis in BLCA patients (Figure 2B), which was validated in GEO and ArrayExpress databases (Figures 2B–G). This evidence concerns the gene COL10A1 and bladder transitional cell carcinoma.
