COL10A1 and bladder transitional cell carcinoma: In our cohort, we divided BLCA patients into two groups with high and low COL10A1 protein expression by IHC staining, and the Kaplan-Meier survival curves indicated that high COL10A1 expression was likely to present a poor clinical outcome than those with low COL10A1 expression (Figure 3F), which further verified the analysis results of sequencing data.
