Figure 5.

Identification of the most stable ECGs in each cell line. Most stable ECGs, i.e. not differentially regulated by different radiation qualities in each cell lines, are identified. Average expression stability M of all remaining control genes after stepwise exclusion of the least stable reference genes in three cell lines are shown. More stably expressed genes are positioned on the right side of the diagram, less stably expressed on the left side. ECGs are ranked in order of their expression stability and presented along x-axis. Stability values (M) determined by geNorm algorithm are presented along y-axis. Low stability value (M) reflects greater stability. For the gene names with their ranking refer Table 2.
