Figure 6. DNA oxidation and genomic DNA modification analyses.

Melanocytes G361 cancer cells were exposed to D₂O + N₂ plasma for 3 min and used for the analyses of DNA oxidation and genomic DNA modification through (A) Circular dichroism; (B) Production of 8-OHdG measured. Each value is the average of three technical replicates. Students' t-test was performed to control (*denotes P<0.05 and **denotes P<0.01); (C) 1%Agarose gel electrophoresis analysis of genomic DNA extracted from the treated G361cells.
