摘要: The proposal has been put forward that the primary cause of Balkan endemic nephropathy (BEN) is exposure to food crops contaminated with seeds Aristolochia spp, which contain high levels aristolochic acids (AA). Recently, tumour DNA samples from patients BEN were found harbour principally A T mutations in TP53 suppressor gene (Grollman et al., Proc Natl Acad Sci USA 2007;104:12129-34). Using a novel mutation assay we can induce and select human sequences vitro by cultured cells mutagen, elicited acid at sites rarely mutated cancers general, but observed patients. This concordance specific patient tumours I-exposed cultures supports argument AA direct role aetiology BEN-associated cancer.
