Sumario: | DNA breakage detection-fluorescence in situ hybridization (DBD-FISH) is a recently developed technique that allows cell-by-cell detection and quantification of DNA breakage in the whole genome or within specific DNA sequences. The present investigation was conducted to adapt the methodology of DBD-FISH to the visualization and evaluation of DNA damage in buccal epithelial cells. DBD-FISH revealed that DNA damage increased significantly according to H(2)O(2) concentration (r(2)=0.91). In conclusion, the DBD-FISH technique is easy to apply in buccal cells and provides prompt results that are easy to interpret. Future studies are needed to investigate the potential applicability of a buccal cell DBD-FISH model to human biomonitoring and nutritional work. |
