Abstract
Objective: Bladder cancer is a highly prevalent disease worldwide. We aimed to investigate the effect of miRNA/mRNA signaling on bladder urothelial carcinoma (BUC).
Methods: MiRNA-139-3p wasselected from The Cancer Genome Atlas database, and its downstream target gene was predicted. The correlation between miRNA-139-3p and intersected mRNAs was analyzed. The mRNA expression levels of miRNA-139-3p and KIF18B in BUC were assayed via quantitative real-time polymerase chain reaction. Effects of miRNA-139-3p on cell proliferation, invasion, migration and cell cycle were detected via Cell Counting Kit-8, colony formation, transwell, wound healing and flow cytometry assays, respectively. Binding relationship between miRNA-139-3p and KIF18B was verified by dual-luciferase reporter gene detection. The protein expression levels of KIF18B, β-catenin and Cyclin D1 were detected by Western blot. Rescue assays were performed for verifying the interaction among miRNA-139-3p, KIF18B and Wnt/β-catenin signaling pathway, which revealed effects of miRNA-139-3p/KIF18B on BUC cells.
Results: MiRNA-139-3p was remarkably underexpressed, and KIF18B was dramatically overexpressed in BUC cells, respectively. It was also demonstrated that overexpressing miRNA-139-3p could prominently inhibit proliferation, invasion and migration of BUC, and block BUC cells at G0-G1 phase. Afterwards, we found that miRNA-139-3p could bind to KIF18B mRNA 3'UTR, and miRNA-139-3p had a negative regulatory effect with KIF18B. Subsequent experimental results presented that overexpressing KIF18B could reverse inhibitory effect of overexpressing miRNA-139-3p on BUC. Finally, this study also ascertained that miRNA-139-3p/KIF18B could repress oncogenic effects of BUC via modulating Wnt/β-catenin signaling pathway.
Conclusion: MiRNA-139-3p/KIF18B/Wnt/β-catenin could significantly inhibit the malignant progression of BUC, and its targeting mechanism might provide an effective therapeutic target for BUC patients.
期刊介绍:
Pharmacogenetics and Genomics is devoted to the rapid publication of research papers, brief review articles and short communications on genetic determinants in response to drugs and other chemicals in humans and animals. The Journal brings together papers from the entire spectrum of biomedical research and science, including biochemistry, bioinformatics, clinical pharmacology, clinical pharmacy, epidemiology, genetics, genomics, molecular biology, pharmacology, pharmaceutical sciences, and toxicology. Under a single cover, the Journal provides a forum for all aspects of the genetics and genomics of host response to exogenous chemicals: from the gene to the clinic.
