Abstract excerpt
Exposure to aristolochic acid I and II (AAI and AAII) has been implicated in aristolochic acid nephropathy and urothelial carcinoma. The toxicological effects of AAs are attributed to their ability to form aristolacatam (AL)-purine DNA adducts. Among these lesions, the AL-adenine (ALI-N6-A and ALII-N6-A) adducts cause the "signature" A → T transversion mutations associated with AA genotoxicity. To provide the...
