A: Relative expression of miR-1238 levels after transfection of miR-NC or miR-1238 inhibitor in U251r and N3r cells. B: Relative expression of miR-1238 levels of NC exosomes and 1238-down exosomes. C: Parallel experiments were performed to evaluate the modulation of the EGFR-PI3K-Akt-mTOR pathway by miR-1238/CAV1 signaling in N3r cells. In all experiments, bars represent mean ± SD for three replicates. (Statistical analysis was performed by Student‘s t-test, *P < .05, **P < .01.)
