The effects of the UV-mimetic chemical 4-nitroquinoline-1-oxide (4-NQO) upon cell lines heterozygous or homozygous for the recessive mutant xeroderma pigmentosum (XP) were investigated. Human lymphoblastoid cell lines, which were established from 4 XP homozygote patients (XPL15, XPL17, XPL19 and XPL20), 2 XP heterozygote individuals (XPPL17 and XPML17) and 58 normal individuals, were cultured in the presence of 4-NQO at doses of 0, 2, 4 and 8 × 10-6 M. Then the total cell number was counted and the viability of the cells was measured by the dye exclusion method using trypan blue and a newly devised fluorometric method with fluorescein diacetate. Results showed that 4-NQO affected, in increasing order of impairment, the cell lines: normal <XP heterozygote < XP homozygote.
