| Abstract | Inhibition of DNA synthesis was studied in γ-irradiated lymphoblastoid cells from patients with Alzheimer's disease and Down's syndrome. A normal biphasic pattern of inhibition was observed over a dose range of 0-4 krad of γ-rays in all of the cell lines. 3 out of 4 Down's and all the Alzheimer's cell lines were shown to be hypersensitive to ionizing radiation based on induced chromosomal aberrations. Increased G2 phase delay, comparable to that occurring in ataxia-telangiectasia cells, was observed for some of the cell lines, after exposure to γ-rays. Contrary to other data in the literature these results demonstrate that radioresistant DNA synthesis is not an intrinsic feature of all disorders characterized by radiosensitivity. © 1989. |
