Figure 5.Osimertinib-resistant exosomes induce the resistance of H1975 cells to osimertinib. (A) Cell viability was assessed by CCK-8 assays. H1975 cells were treated with different concentrations of AZD9291 for 48h. (B) Cell viability was assessed by CCK-8 assays. H1975 cells were treated with AZD9291 and then incubated with different concentrations of osimertinib-resistant exosomes. (C) qRT-PCR determined the relative expression of lncRNA MSTRG.292666.16.
