Figure 9. NSCLC cell-derived exosomes with RAB35 knockdown or miR-185-5p overexpression (Enzyme treated) inhibited NSCLC cell migration and invasion. The exosomes secreted by A549 cells and H2170 cells were treated with enzyme and then added into the two kinds of cell models with downregulation of RAB35. (A) Transwell cell migration assay was used to measure the migration of A549 cells and H2170 cells, and the results showed that the promoting effects of exosomes secreted by A549 and H2170 cells on cell migration and invasion were attenuated under the action of enzymes. (B) The cell invasion was detected by Transwell cell invasion assay. N=6, ** P<0.01.
