Western blots of phosphorylated S6K (Thr389) in MCT-1 (A) and MCT-2 (B) lysates 30 min to 24 h after exposure to 3, 6, or 10 Gy. For the densitometry analysis of MCT-1 (C) and MCT-2 (D), the ratio of p-S6K:native S6K:tubulin was calculated for each treatment and normalized to the DMSO control for that time point.
