MiR-1238 levels in serum and GBM exosomes correlate with TMZ resistance. A: Relative expression of miR-1238 in serum samples was measured by RT-qPCR. B: Relative expression of miR-1238 in serum samples was measured by RT-qPCR. C: Relative expression of miR-1238 in culture medium (CM) of GBM cells was measured by RT-qPCR. D: Relative expression of miR-1238 in exosomes of GBM cells was measured by RT-qPCR. In all experiments, data are mean ± SD of triplicate measurements. (Statistical analysis was performed by Student‘s t-test, *P < .05, **P < .01.)
