MIR497HG and bladder transitional cell carcinoma: Furthermore, we analyzed The Cancer Genome Atlas (TCGA) bladder urothelial carcinoma RNA sequencing data and revealed that the expression levels of miR-497 and miR-195 were inhibited in various stage of BCa (Figures 1E,F), and these data also showed that MIR497HG was downregulated in BCa (Figure 1G).
