Number of genes whose translation state was affected by radiation in cell lines as a function of the tissue of origin

Tissue of origin	Down-regulated	Up-regulated
Breast tumors	796	711
Lung tumors	397	382
Glioma	1,398	1,566
Pancreas tumors	2,279	1,844
Normal	1,385	1,974

NOTE: Genes that were significantly different between untreated and radiation-treated samples were identified using the two-class paired response parameter SAM (<1% FDR) for the cell lines corresponding to each tissue of origin.
