A human-mouse hybrid containing a human 11q22–23 fragment including theATM locus was used to examine its capability to correct the cellular defect of ataxia-telangiectasia (A-T). Examination of 21 A-T-derived hybrids indicated that the acquired radioresistance was observed in the clones where the 11q22–23 fragment was transferred intact, but not in those where donorderived 11q segment was lost. In one exceptional clone, theATM locus was deleted from the transferred fragment, while it was still partially radioresistant. This partially radioresistant clone was found to include the mouse-derived fragment containing theAtm gene, the mouse homologue of humanATM gene. Similar association of partial radioresistance with the presence of mouseAtm gene was observed in three additional hybrids. The results indicate that the cellular A-T defect can be corrected by the mouse subchromosomal fragment containing theAtm gene as well as by the human 11q22–23 fragment containing theATM gene, but apparently to a lesser extent in the former.
