4-Hydroxyestrone is an endogenous estrogen metabolite, which exhibits a strong neuroprotective effect against oxidative damage. It also provides effective protection against kanic acid-induced hippocampal oxidative damage in rats when compared to 17β-estradiol. 4-Hydroxyestrone regulates the angiogenic process during corpus luteum formation. It might be involved in an increased risk of cancer. 4-Hydroxyestrone is found in the early and mid-luteal phases.

Catechol estrogen quinones (CEQ) derived from 4-hydroxyestrone (4-OHE1) and 4-hydroxyestradiol (4-OHE2) react with DNA to form depurinating--N7Gua and--N3Ade adducts. This damage leads to mutations that can initiate breast and prostate cancer. To determine whether this damage occurs in humans, urine

Catechol estrogens are major estrogen metabolites in mammals and are the most potent naturally occurring inhibitors of catecholamine metabolism. These estrogen compounds have been implicated in carcinogenic activity and the 4/2-hydroxyestradiol concentration has been shown to be elevated in neoplastic

4-Hydroxyestrone (4-OHE(1)), a typical cancer-inducing metabolite, originating from 17beta-estradiol (17beta-E2), was chosen as a model for the studies. The aim was to get a deeper insight in the mechanisms of its ability to initiate cancer. It was found, that 4-OHE(1)

Estrogens, including the natural hormones estrone (E(1)) and estradiol (E(2)), are thought to be involved in tumor induction. Catechol estrogen quinones (CEQ) derived from 4-hydroxyestrone (4-OHE(1)) and 4-hydroxyestradiol (4-OHE(2)) react with DNA and form depurinating N7Gua and N3Ade adducts that

Free radical generation by metabolic redox cycling between catechol estrogens and their quinones and subsequent hydroxyl radical damage to DNA have been proposed to mediate estrogen-induced renal carcinogenesis in the hamster. In this study the content of 8-hydroxy-2'-deoxy-guanosine (8-OHdG), a
