Number of selected candidate mRNAs (shown on the y-axis) discriminating the three comparisons of (panel A) TBI vs. PBI, (panel B) TBI vs. LHB, (panel C) UBE vs. LHB over time after irradiation (in days, x axis). (Note that the scale of the y-axis is not the same for A through D). Up- and downregulated mRNAs are shown for each comparison as well as the sum of both. Gray areas represent the time interval with the highest number of deregulated mRNAs. Panel D: Corresponding data for miRNAs from our previously published study [TBI vs. PBI, (14)]. TBI = total-body irradiation; PBI = partial-body irradiation; LHB= left hemibody exposure; UBE = upper body exposure.
