An exosome derived from a cancer cell has been identified to regulate intercellular communication. However, the roles of oral cancer-derived ectodomains in tumor metastasis need to be investigated further. We investigated their roles in oral cancer cells in this paper. The enforcing effect on oral cancer cells was attributed primarily to miR-10b, a gene with a high level in exosomes that is transferred to recipient cells via oral cancer-derived exosomes. Exosomes were obtained by exosome isolation reagents. Also, exosome identification and analysis were performed by electron microscopy. The expression of miRNAs was analyzed by qRT-PCR. Protein expression was analyzed by Western blot. Also, invasion and migration experiments were performed to assay and evaluate the function of exosomal miR-10b. Exosome-mediated transfer of miR-10b promoted oral cancer cell behaviors, according to the findings. Finally, it was discovered that AKT signaling participates in regulating exosome-mediated invasion and migration of oral cancer cells and its activation reduced the inhibitory effect of miR-10b knockdown on oral cancer cells. Exosomal miR-10b derived from oral cancer cells enhances cell invasion and migration by activating AKT signaling.
