Furthermore, we found that patients with high CXCL10 expression in TCGA-BLCA have a higher tumor mutation burden (TMB) (Fig. 3C, p < 0.001), however, our analysis indicated no significant difference in microsatellite instability (MSI) within the CXCL10 subgroups (Fig. 3D, p = 0.29). This evidence concerns the gene CXCL10 and bladder transitional cell carcinoma.
