The dysplastic nevus syndrome (DNS) is a preneoplaslic melanocyle abnormality which occurs in families affected by hereditary cutaneous malignant melanoma (HCMM). A putative role of host-environmental interactions in the etiology of hereditary melanoma has been strengthened by the recent finding that fibroblasts derived from HCMM/DNS patients demonstrated enhanced sensitivity to u.v. irradiationin vitro. We report here an extension of these studies in which we have examined thein vitroresponses to a model environmental carcinogen, 4-nitroquinoline 1-oxide (4NQO), of six non-tumour skin fibroblast strains from HCMM/DNS patients representing five families. Three of the six HCMM/DNS strains showed enhanced cell killing with sensitivities greater than that of a xeroderma pigmentosum (XP) variant strain but less than those of ataxia telangiectasia and XP Group D cell strains. The inhibition and recovery ofde novoDNA synthesis, together with the expression of repair synthesis, following 4NQO exposure appeared to be normal in HCMM/DNS strains, irrespective of their subsequent clonogenic potential. Our data point to a metabolic anomaly which may contribute to the carcinogenic risk of the melanoma prone preneoplaslic state presented by some DNS patients.
