Fig. 1From: Transcriptomic analyses of the radiation response in head and neck squamous cell carcinoma subclones with different radiation sensitivity: time-course gene expression profiles and gene association networksDose-survival curves of parental CAL-33 cell line and derived subclones. The linear-quadratic cell survival curves were fitted to the measured data using maximum-likelihood method. Both subclones (SP and RP) showed statistically significant difference (p-values < 0.0001) in response to ionizing radiation compared to the parental CAL-33 cell lineBack to article page
