miR-653 Induces Bone Marrow Mesenchymal Stem Cells Proliferation via Activating Epithelial-Mesenchymal Transition in Oral Squamous Cell Carcinoma
This study intends to assess miR-653’s expression in MSCs and OSCC and discuss molecular biological mechanism of changes of EMT in MSCs through activating miR-653 in OSCC. miR-653 expression in MSCs and OSCC was detected. si-miR-653 was transfected into MSCs followed by analysis of cell proliferation by CCK-8 and clone formation assay, cell apoptosis and cycle by FCM, and the changes of transcription factor as ZEB1 and Snail by qRT-PCR. miR-653 expression in OSCC cell was up-regulated significantly from the result of q-RT-PCR detection. The proliferation of MSCs induced by miR-653 was restrained and apoptotic rate was increased after treatment with si-miR-653 along with stagnated cycle of G1/G0 staging cell. The expression of transcription factor of EMT type as ZEB1 and Snail was elevated significantly after intervention using si-miR-653. In conclusion, the proliferation of OSCC could be induced by MSCs through activation with miR-653 which might be through regulation of EMT process.
