RT activates the EGFR signaling and up-regulates the PD-L1 expression in glioma cells.

The EGFR signaling and PD-L1 protein level in U87 and U251 cell lines were detected at 24, 48 and 72 h after 5 or 10 Gy irradiation. Representative images and quantitative data are shown. Each column is shown as the means of three separate experiments; bars, SD. ANOVA; *P < 0.05; **P < 0.01; ***P < 0.001; versus 0 Gy group.
