Journal ArticleDOI
A review of brain aromatase cytochrome P450
TL;DR: It is clear that molecular mechanism(s) account for the diverse expression of aromatase in different neural tissue sites and during various physiological states or developmental periods and further study is necessary in order to understand the significance of the regulation of local estrogen biosynthesis by the arom atase cytochrome P450 gene during prenatal and postnatal development.
Journal ArticleDOI
S-Equol, a potent ligand for estrogen receptor β, is the exclusive enantiomeric form of the soy isoflavone metabolite produced by human intestinal bacterial flora
Kenneth D.R. Setchell,Carlo Alfredo Clerici,Edwin D. Lephart,Sidney J Cole,Claire Heenan,Danilo Castellani,Brian Wolfe,Linda Nechemias-Zimmer,Nadine M Brown,Trent D. Lund,Robert J. Handa,James E. Heubi,James E. Heubi +12 more
TL;DR: Humans have acquired an ability to exclusively synthesize S-equol from the precursor soy isoflavone daidzein, and it is significant that this enantiomer has a relatively high affinity for estrogen receptor beta.
Journal ArticleDOI
Equol Is a Novel Anti-Androgen that Inhibits Prostate Growth and Hormone Feedback
Trent D. Lund,Daniel J Munson,Megan E. Haldy,Kenneth D.R. Setchell,Edwin D. Lephart,Robert J. Handa +5 more
TL;DR: The significance of equol's ability to specifically bind and sequester DHT from the androgen receptor have important ramifications in health and disease and may indicate a broad and important usage for equol in the treatment of androgen-mediated pathologies.
Journal ArticleDOI
Dietary soy-phytoestrogens decrease testosterone levels and prostate weight without altering LH, prostate 5alpha-reductase or testicular steroidogenic acute regulatory peptide levels in adult male Sprague-Dawley rats
TL;DR: The results indicated that consumption of dietary phytoestrogens resulting in very high plasma isoflavone levels over a relatively short period can significantly alter body and prostate weight and plasma androgen hormone levels without affecting gonadotropin or testicular StAR levels.
Journal ArticleDOI
Neurobehavioral effects of dietary soy phytoestrogens
Edwin D. Lephart,Timothy W. West,K. Scott Weber,Reuben W. Rhees,Kenneth D.R. Setchell,Herman Adlercreutz,Trent D Lund +6 more
TL;DR: In this article, the influence of phytoestrogens on brain structure, learning, memory and anxiety along with the brain androgen-metabolizing enzyme, aromatase, was investigated in perinatal, maternal or adult rats.
