An SV40-transformed
Fanconi's anaemia
(FA) cell line, GM6914, exhibits approximately 2.4-fold increased sensitivity to the cytotoxic effects of nitrogen mustard (NM) when compared with the normal line, MRC5-V1. Host cell reactivation of NM-treated plasmid has been investigated using transient expression vectors which contain the
chloramphenicol acetyltransferase
(
CAT
) gene. In both cell types there is a similar, dose-dependent reduction in
CAT
expression which correlates with an increase in NM-induced DNA-interstrand crosslinking. The data are consistent with two possible mechanisms for inactivation of the plasmid. Either a single crosslink anywhere within the plasmid is sufficient to prevent transcription of the cat gene. Alternatively, inactivation may result from some other more prevalent NM-induced lesions within the cat coding sequence.
