Genetic analyses of the PARP-1 gene have demonstrated alterations in neoplasms, and a mutation affecting the conserved amino acid E251 in germ cell tumors, as well as an association of a single-nucleotide polymorphism V762A with risk of prostate cancer.
This study is the first to provide evidence that the ADPRT V762A-genetic variant contributes to CaP susceptibility and altered ADPRT/PARP-1 enzyme function in response to oxidative damage.
