PCA scores and loading plots. (A) 2D PCA scores of DNA adducts obtained from adductome analysis. Principal components PC1 and PC2, which explains 74.25% of the total variance observed, discriminate the MGT-treated group from the vehicle control; (B) The PC1 and PC2 variable loading plots. Numbers A1–A53 represents DNA adducts observed in DNA adductome analysis.
