Table 3. Radiation-induced microRNA expression changes in rat mammary gland.

Relative miR expression values are represented in folds in the irradiated cells in comparison to non-irradiated control cells as analyzed by miRNA microarray. Significance of differences was analyzed by the Student's t-test.
