| Research Abstract |
It is known that nematode shows strong radiation tolerance. In response to harsh environmental conditions, nematode C. elegans larvae undergo dauer stage and recover the normal stage by environmental reform. Modest doses X-irradiation of dauer larvae increased their post-dauer longevity. We founded that the gene expressions of some enzymes of metabolic regulation/anti-oxidation related with metabolic regulation/stress response were up-regulated in the X-ray irradiated dauer larvae. Especially, it is suggested that a transcription factor, mxl-3 plays a role of radiation tolerance
