Whilst estrogens induce cancers in rodent bioassays and in spite of several studies on the pathogenetic mechanism, it is still unclear the relative role of genotoxic (such as metabolic redox cycling to generate free radicals such as superoxide and epigenetic action (growth stimulation, modulation of oncogene expression, metabolic cooxidation of arachidonic acids to prostaglandins). Here we reported the in vitro genotoxic evaluation of the early estradiol catecholoestrogens metabolites: 4OH-Estradiol, 2OH-Estradiol, 2OH-Estrone, 4OH-Estrone, 16-alfaOH-Estrone.
