Fig. 5: Quantitative real-time PCR analysis for mRNA levels of the candidate genes in wild-type GBM cells and irradiation-resistant GBM cells.

A CARHSP1 mRNA level in U87 cells was detected, the irradiation-resistant cells of U87 cells were enriched by treating with 12 Gy radiation for three rounds. B CARHSP1 mRNA level in U251 cells was detected, the irradiation-resistant cells of U251 cells were enriched by treating with 15 Gy radiation for three rounds. Data were represented as means ± SD of three independent experiments.
