Abstract Objective To explore the effectsof laryngeal carcinoma exosomal miR-20a on the proliferation and apoptosis of tumor-associated macrophages. Methods The exosomes secreted by 16HBE, TU686, TU177 and TU212 cells were extracted and identified (recorded as 16HBE exo, TU686 exo, TU177 exo and TU212 exo). TU212 cells were transfected with miR-NC and miR-20a mimic, and the exosomes secreted by TU212after transfection were collected (recorded as miR-NC exo and miR-20a exo). M2 macrophages were incubated with PBS, 16HBE exo, TU686 exo, TU177 exo, TU212 exo, miR-NC exoand miR-20a exo for 48 h (listed as PBS group, 16HBE exo group, TU686 exo group, TU177 exo group, TU212 exo group, miR-NC exo group and miR-20a exo group). The proliferation ability of cells was detected by CCK8 method, the apoptosis rate of cells was detected by flow cytometry,and PI3K and AKT phosphorylation levels in cells in each group were detected by Western blotting. Results The extracted exosomes were consistent with their structural and biological characteristics. The proliferation ability of M2 type macrophages in the TU686 exo group, TU177 exo group, and TU212 exo group were significantly higher than that in the PBS group (P<0.05), the apoptosis rate (9.67%±1.53%, 8.67%±2.08%, 4.00%±1.00%) was significantly lower than that in the PBS group (21.67%±4.72%) (P<0.01), the phosphorylation levels of PI3K (0.81±0.03, 0.70±0.03, 1.10±0.08) and AKT (1.55±0.11, 1.86±0.06, 2.13±0.10) were significantly higher than those in the PBS group (0.19±0.04 and 0.11±0.03) (P<0.001), the proliferation ability of M2 type macrophages in the miR-20a exo group was significantly higher than that in the miR-NC exo group (P<0.05), and the apoptosis rate (8.33%±1.52%) was significantly lower than that in the miR-NC exo group (14.33%±1.53%) (P<0.01). The phosphorylation levels of PI3K (1.05±0.09) and AKT (1.55±0.11) were significantly higher than those in the miR-NC exo group (0.11±0.04 and 1.19±0.03) (P<0.001). Conclusions Laryngeal carcinoma exosomal miR-20a can regulate the proliferation and apoptosis of M2 macrophages, and the mechanism may be the activation of PI3K/AKT signaling pathway.
