Fig. 2From: Radiation dose-rate effects on gene expression for human biodosimetryValidation of microarray results by qRT-PCR. Shown here are log2 (fold changes) of genes that were determined to be differentially regulated by the 4.45Â Gy dose by both dose-rates. The graph on the left shows the mean log2 (fold change) after LDR 4.45Â Gy; and the graph on the right is the mean of log2 (fold change) after Acute 4.45Â Gy exposure. All microarray (blue bars, five biological replicates) and qRT-PCR (red-bars, three biological replicates) results are average fold-change from paired analyses; SEM values for all data are included in Additional file 4Back to article page
