Preferential induction of FOXM1 expression is associated with radioresistance of quiescent HNSCC. Q-RT-PCR measurements of expression of oxidative stress response genes in control and irradiated proliferating (panel A) and quiescent (panel B) Cal27 cells. Asterisks represent statistical significance compared to individual mRNAs in unirradiated cells. n =3; P < 0.05. FOXM1 mRNA and protein levels in 0–8 Gy irradiated quiescent Cal27 (panel C) and FaDu (panel D) cells measured at 48 h postirradiation. Asterisks represent statistical significance compared to unirradiated cells. n = 3; P < 0.05.
