Figure 7. Functional validation assay of exosomes circRNA_102481 on EGFR-TKIs sensitive cells in vitro (n=3).(A, B) MTT assay showed the effects of circRNA_102481 on EGFR-TKIs sensitive cell proliferation. (C, D) Annexin V/PI assay showed the effects of circRNA_102481 on EGFR-TKIs sensitive cell apoptosis. circRNA_100859 vector: circRNA_100859 overexpression vector. *p<0.05 versus blank vector group.
