The content of nucleic acid components in numerous foods, especially carbohydrate-rich ones, has been investigated. The data obtained for bases (purines and pyrimidines) were calculated as nucleic-acid equivalents (RNA or DNA); the IMP content was calculated from the measured content of
Pierisin-1, an ADP-ribosylating toxin derived from the cabbage butterfly, Pieris rapae, induces apoptosis in various mammalian cell lines. We recently reported that the target for ADP ribosylation by pierisin-1 is the 2'-deoxyguanosine residue in DNA. To examine whether pierisin-1 would induce
Brassica oleracea L. var. costata DC leaves and Pieris brassicae L. larvae aqueous extracts were assayed for their potential to prevent/induce DNA damage. None of them was mutagenic at the tested concentrations in the Ames test reversion assay using Salmonella His(+) TA98 strains, with and without
