The pathway enrichment analysis results of the (5 cGy +2 Gy) group at different time points.

<p>The KEGG, REACTOME and WikiPathways databases in ClueGO were employed for pathway enrichment analysis of each differential group gene sets acquired from microarray analyses. The Enrichment/Depletion was tested by the two-side hypergeometric test, and the Benjamini and Hochberg false-discovery rate was set to 0.05. The green and red colors code for down-regulation and up-regulation of genes, respectively, in each group.
