Fig. 2.

Heat map illustrating relative gene expression at days 1 and 7 post-irradiation. Hierarchical cluster analysis was performed on 494 probesets responding to both 1 Gy neutrons and 1 and 4 Gy x-rays relative to unexposed controls at either 1 or 7 days after exposure. Red indicates high expression, green indicates low expression as indicated in the color key. Each row represents one gene and each column represents an individual mouse, ordered by exposure dose and radiation type as labeled in the figure
