• Descrição: 4-Hydroxy-17β-estradiol (4-OHE2) is a reactive metabolite of 17β-estradiol that binds to DNA and has been shown to have carcinogenic potential. The catechol-o-methyltransferase enzyme catalyzes the conversion of 4-OHE2 to 4-hydroxycatechol, which can then be further methylated by estrogen sulfotransferase or sulfatase to estrone and estrone sulfate. It has been shown that 4-OHE2 may be a potential biomarker for breast cancer. Experimental studies have shown that 4-OHE2 may act as an antioxidant in cancer tissues, but its activity has not been demonstrated in normal tissues. In order to demonstrate the ability of 4-OHE2 as an antioxidant, its activity was tested in vitro using human breast cancer cells (MDA MB 231). Results showed that 4-OHE2 decreased oxidative stress levels in these cells,
