Outline of Final Research Achievements

Based on the microRNAs expression profile by next generation sequencing in bladder cancer (BC), we identified several downregulated microRNAs including miR-223, miR-199 family, miR-145-5p/3p, miR-139-5p/3p, miR-26a/b-5 and found their target tumor-associated genes in BC. Finally, we found that these microRNAs may have tumor-suppressive function via direct targeting of oncogenic genes including WDR62, CCNE1/2, UHRF1, PLOD2, and ITGA3. Thus, it was revealed that several important cancer signaling pathways like cell cycle, gene’s methylation, remodeling collagens in tumor matrix, and integrin signal might be regulated by microRNA network. According to these microRNA-axis study, we obtained basic data for new therapeutic strategy by using drugs that inhibit these signaling pathways.
