Since the radiation effects by low-dose-rate irradiation were difficult to detect comparing to the high-dose-rate irradiation, we have not been able to understand the mechanism of the specific biological reaction of the low-dose-rate irradiation. To understand the low-dose-rate specific biological response, C57BL/6J mice were continuously irradiated with gamma-rays for 485 days at the dose rates in the range of 32 - 13,000 nGy/min whose levels were as low as about 15 times to 65,000 times over the natural background. Gene expression profiles in the kidneys from irradiated and unirradiated mice were analyzed and differentially expressed genes were identified after quality control of the data. In order to get more information of the specific pathway, we used the Boomerang program which adopted the algorithm (1) of SHAFT (2) and showed the possibility of the participation of p53 transcription factor. The results suggested that it is likely to be able to obtain more information by using the specializing method of dealing with the inclusive data even if it might be a very small response as it was not detectable., CBI学会2008年大会}, title = {New Bioinformatics program for the extraction of biological intelligence}, year = {2008} }
