Fig. 3. Measurement of (+)-anti-trans-B[a]PDE-dGuo in H358 cells after chemical inhibition.
H358 cells were treated with 2 μM (−)-B[a]P-7,8-dihydrodiol for 24 h with or without 1 mM probenecid for 24 h and/or 10 nM TCDD for 24 h. (+)-anti-trans-B[a]PDE-dGuo adducts were measured by LC-SRM/MS and normalized by total DNA. Plots show means and standard deviation, (*) indicates p=0.001 compared to control and (**) indicates p=0.013 compared to control; n = 3 for each treatment.
