This study aims at investigating the mechanism underlying bone marrow mesenchymal stem cells (BMSC) function in glioma. Glioma cells were administered with plasmids loading NF-κB siRNA, microRNA (miRNA)-189 inhibitor, or miR-189 mimics for transfection followed by analysis of miR-189 expression by RT-qPCR, cell apoptosis by flow cytometry, cell proliferation by MTT assay,invasion and migration by Transwell assay, inflammatory factors secretion by ELISA as well as proteins expression by western blot. A mouse model of glioma was established to detect the in vivo effect of BMSCs. miR-189 was lowly expressed in glioma cell lines but enriched in BMSCs. When miR-189 was silenced, cell proliferation, invasion and migration were potentiated and apoptosis was decreased, along with enhancement of N-cadherin, Vimentin, MMP-2 and and MMP-9, and decline in Bax, cleaved casepase-3 and cleaved PARP. Silencing of NF-κB reversed the effect of miR-189 inhibitor on cell progression, accompanied with reduction of inflammatory factors. BMSCs treatment effectively promoted miR-189 expression in glioma and inactivated TNF-α/NF-κB signaling, thereby suppressing tumor growth. In conclusion, miR-189 derived from BMSC inhibits glioma progression through regulation of TNF-α/NF-κB signaling pathway.
