Figure 3. Results of knockdown of five regulators of radiation-expression phenotypes.
Regulators of expression levels of radiation-responsive genes were knocked down by siRNAs. Changes in expression levels of the regulators and their corresponding target genes after knockdown of the regulators are shown, as are changes in expression levels of a control gene (encoding glyceraldehyde-3-phosphate dehydrogenase) after knockdown of the regulators. Data are shown as means ± s.e.m. for four or more independent transfections. Asterisk, P < 0.05; two asterisks, P = 0.07; no symbol, P > 0.05.
