Apple Flavonoids Suppress Carcinogen-Induced DNA Damage in Normal Human Bronchial Epithelial Cells

Figure 5

(a) DNA tail damage in BEAS-2B cells exposed to either carcinogen alone or in combination with pretreatment of AF4, as assessed by comet assay. (b) Quantification of DNA tail damage using OpenComet freeware. At least 50 comets for each sample were analyzed and examined with a fluorescence microscopy under 40x. Experimental values presented as mean ± SD of independent experiments. indicated statistical difference at .
