Molecular carcinogenesis, 31(3), 111-124 (2001-08-02)
2-Methoxyestradiol (2-ME), an endogenous metabolite of 17beta-estradiol, is present in human blood and urine. Here we show for the first time that 2-ME significantly inhibited the growth of normal prostate epithelial cells and androgen-dependent LNCaP and androgen-independent DU145 prostate cancer

Rapid communications in mass spectrometry : RCM, 19(9), 1176-1182 (2005-04-09)
A liquid chromatography/tandem mass spectrometric (LC/MS/MS) assay was developed for the quantitative determination of 2-methoxyestradiol (2ME2) in human plasma. Sample pretreatment involved liquid-liquid extraction with ethyl acetate of 0.3-mL aliquots of plasma spiked with the internal standard, deuterated 2ME2 (2ME2-d5).
S Sarkar et al.
Oncogene, 33(1), 26-33 (2012-12-19)
The androgen receptor (AR) has a vital role in the onset and progression of prostate cancer by promoting G1-S progression, possibly by functioning as a licensing factor for DNA replication. We here report that low dose 2-methoxyestradiol (2-ME), an endogenous
