| Popis: | Abstract. Background. Glioblastoma is one of the most common malignant brain tumors. Conventional clinical treatment of glioblastoma is not sufficient, and the molecular mechanism underlying the initiation and development of this disease remains unclear. Our study aimed to explore the expression and function of miR-873a-5p in glioblastoma and related molecular mechanism. Methods. We analyzed the most dysregulated microRNAs from the Gene Expression Omnibus (GEO) database and examined the expression of miR-873-5p in 20 glioblastoma tissues compared with ten normal brain tissues collected in the Zhejiang Tongde Hospital. We then overexpressed or inhibited miR-873-5p expression in U87 glioblastoma cell lines and analyzed the phenotype using the cell counting kit-8 assay, wound healing assay, and apoptosis. In addition, we predicted upstream and downstream genes of miR-873-5p in glioblastoma using bioinformatics analysis and tested our hypothesis in U87 cells using the luciferase reporter gene assay and Western blotting assay. The differences between two groups were analyzed by Student's t test. The Kruskal-Wallis test was used for the comparison of multiple groups. A P |
