Gene Expression Profiling of Biological Pathway Alterations by Radiation Exposure

Table 1

Number of total differentially expressed genes.

Comparison (Gy)	Upregulated genes	Downregulated genes
0 versus 0.5	13	41
0 versus 1	430	398
0 versus 2.5	111	76
0 versus 5	106	299

Standard selection criteria to identify differentially expressed genes are as follows: and ; ratios = “NA” and the differences of intensity between the two samples (duplicated chip) ≥1000 was excluded.
