The Radiation Genes Database collects microarrays data on transcriptional effects of ionozing radiation obtained from public repositories or from published papers.

Data are provided to the public via a website that contains a user-friendly search interface and several tools and web services which should facilitate comparison and meta-clustering analysis.

This database should allow researchers working on transcriptional response of mammalian cells to radiation to ask important questions for radiobiologists:

• Which genes show a general transcriptional response to irradiation in different biological systems in vitro and in vivo?
• Which genes show a general response to a wide range of doses and to different quality of irradiation (i.e. low or high Linear Energy Transfer) ?
• Which genes show an early and transient response and which show instead a long range modulation?
