| Research Abstract |
We have investigated phenotypes and genotypes of cells from patients with Nijmegen breakage syndrome.
1. NBS cells partially repressed the induction of p53 and phosphorylation of p53 (ser-15) after irradiation.
2. NBS cells showed the defect in apoptic response to radiation.
3. For the perpose of prenatal diagnosis, we analyzed mutation in NBS gene of patients and haplotype of parental DNA.
4. We investigated mechanism of NBS1 in chromosomal stability, radiation sensitivity and signal transduction, which include ATM, Histon H2AX, p53, NBS, hMre11, Ku.
