This study investigated the role of miR-1592 carried by exosomes derived from BMSCs in glioma. The results showed that BMSC-derived exosomes can suppress the development of glioma in vivo and in vitro by interfering with the PI3K/AKT signaling pathway, including inhibiting cell invasion, metastasis, apoptosis, and proliferation.
This study evaluated the role of miRNA-1592 (miR-1592) carried by exosomes that originated from bone marrow mesenchymal stem cell (BMSC) in glioma. BMSCs were cultured and identified, followed by being co-cultured with glioma cells to measure cell invasion, metastasis, and apoptosis by transwell assay and flow cytometry, cell proliferation by MTT, PI3K/AKT signal protein expression by western blot. BMSC-originated exosomes with different concentrations were used as a treatment strategy for established tumor models. The tumor volume was measured and tumor tissues were harvested for immunohistochemistry and immunoblot analysis. After co-culture with BMSC-originated exosomes, glioma cells showed an up-regulated transcription of miR-1592, along with inhibited phosphorylation and activation of PI3K/AKT signal pathway. Moreover, glioma cells exhibited reduced migration and invasiveness in vitro, which was accompanied by diminished levels of proteins involved in cellular invasiveness. Simultaneously, co-culture with BMSC-originated exosomes can restrain glioma cell proliferation via facilitating cell apoptosis in vivo and in vitro. In conclusion, exosome-encapsulated microRNA-1592 from BMSCs can suppress the in vivo and in vitro development of glioma through interfering with PI3K/AKT signaling pathway.
