Fig 2. Workflow of data analysis.

Of the 450 genes measured from 12 hours to 3 weeks post-2 Gy irradiation, 301 were reliably detected. Analysis of the temporal expression profiles identified 78 differential genes that finally gave rise to the definition of 43 clusters of expression with 49 genes, and the detection of 47 putative transcription factors (TFs). At the end, occurrences of TFs and differential genes allowed us to propose biological perspectives by analysis of molecular pathways and network interactions.
