| Abstract | Recent reports from a number of laboratories have linked radiosensitivity in ataxia telangiectasia (A-T) to a large and prolonged block of some cells in G2 phase. Previous results from this laboratory, largely with one Epstein-Barr virus-transformed A-T lymphoblastoid cell line, presented evidence for a dramatic increase in the number of cells in G2 phase over controls during a 24-h period post irradiation. We describe here a study of the effect of γ-radiation on G2 phase delay in several A-T cell lines. Based on previous results with several cell lines 24 h post irradiation was selected as the optimum time to discriminate between G2 phase delay in control and A-T cells. All A-T homozygotes showed a significantly greater number of cells in G2 phase, 24 h post irradiation, than observed in controls. A more prolonged delay in G2 phase after irradiation was seen in different A-T cell types that included lymphoblastoid cells, fibroblasts and SV40-transformed fibroblasts. At the radiation dose used it was not possible to distinguish A-T heterozygotes from controls. © 1989. |
