Genotoxicity of human milk extracts and detection of DNA damage in exfoliated cells recovered from breast milk.

Abstract excerpt

Genotoxic agents of environmental or dietary origin may play a role in breast cancer initiation. The ability of extracts of human milk to cause mutations in S. typhimurium TA1538 and YG1019 and to induce micronuclei and DNA strand breaks in MCL-5 cells was investigated. Twenty samples from different donors were analysed and of these, 6 were adjudged to produce positive mutagenic response in one or both bacterial...
