Kinds and location of mutations induced by (+/-)-7 beta,8 alpha-dihydroxy-9 alpha,10 alpha-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene in the coding region of the hypoxanthine (guanine) phosphoribosyltransferase gene in diploid human fibroblasts.

Abstract excerpt

To gain insight into the mechanisms by which mutations are induced in human cells by carcinogens, we have determined the kinds and location (spectrum) of mutations induced in the coding region of the hypoxanthine (guanine) phosphoribosyltransferase (HPRT) gene by (+/-)-7 beta, 8 alpha-dihydroxy-9 alpha, 10 alpha-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE). Individual populations of diploid human fibroblasts...
