Homo sapiens 141-144 10676627-4 2000 These results demonstrate a dependence on p53 for the efficient repair of BPDE adducts at levels that are relevant to human environmental exposure and, thus, have significant implications for human carcinogenesis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 74-78 tumor protein p53 Homo sapiens 42-45 10446162-2 1999 It has recently been shown that BPDE
