The results showed that there were significant differences among HSP90B1, YIF1A and SRPRB in the pathological stages (p < 0.05) but no significant difference was observed between TRIB3 and CALR (p > 0.05) (Figure 6A) Subsequently, we also analysed the differential expression of CALR, HSP90B1, SRPRB, YIF1A and TRIB3 in high-grade BLCA (n = 384) and low-grade BLCA (n = 21) samples. This evidence concerns the gene HSP90B1 and bladder transitional cell carcinoma.
