description |
Rorippa nasturtium-aquaticum (watercress) is recognized as a nutritious plant, rich in vitamins
and minerals and it is used in the treatment of many illnesses. The aim of the present work was to develop
a genotoxic analysis of this diet component considering human intake by means of effect biomarkers
such as mitotic index, cellular proliferation kinetic, sister chromatid exchanges, micronucleus frequency
and single cell gel electrophoresis (comet assay), allowing to establish risk-benefit in the consumption of
this vegetable. The cress plant was chopped; the obtained product was centrifuged, filtered (0.22 µm) and
conserved to -20 ºC. Two concentrations of the aqueous extract (13.2-26.4 mg/ml of culture) were assayed
in human peripheral blood culture of healthy volunteers. No statistically significant differences were detected
in our experimental conditions for any of the evaluated biomarkers (p > 0.05). These findings indicate
that the watercress extract would not induce cytotoxicity, chromosomal instability, clastogenicity or
DNA double and single strand breaks or alkali-labiles sites. Hence, monitoring the toxicogenetic activity of
different aqueous extracts would provide a better understanding of their potential ability to improve
healthiness or prevent DNA damage. |
