Original Investigations


Fanconi anaemia (FA) cells are extremely sensitive to crosslinking agents, e. g. mitomycin C, but only moderately sensitive to trimethylpsoralen plus UVA. Evidence has been reported suggesting that there is a deficient DNA crosslink repair mechanism in FA cells, but others failed to confirm this conclusion using other methods and other crosslinking agents. We reinvestigated the mitomycin C and 8-methoxypsoralen crosslink repair in FA cells with a high sensitivity to mitomycin C. Although an essentially similar methodology was used to that previously described, no difference between the control and FA cell strains was observed, neither for mitomycin C- nor for 8-methoxypsoralen-induced crosslinks.
