Insights into subtle conformational differences in the substrate-binding loop of fungal 17β-hydroxysteroid dehydrogenase: a combined structural and kinetic approach.

Alberto Cassetta et al.

The Biochemical journal, 441(1), 151-160 (2011-09-21)

The 17β-HSD (17β-hydroxysteroid dehydrogenase) from the filamentous fungus Cochliobolus lunatus (17β-HSDcl) is a NADP(H)-dependent enzyme that preferentially catalyses the interconversion of inactive 17-oxo-steroids and their active 17β-hydroxy counterparts. 17β-HSDcl belongs to the SDR (short-chain dehydrogenase/reductase) superfamily. It is currently the

The protective effects of coumestrol against amyloid-β peptide- and lipopolysaccharide-induced toxicity on mice astrocytes.

Man-Hai Liu et al.

Neurological research, 33(6), 663-672 (2011-06-29)

Estrogen replacement therapy can decrease the risk of developing Alzheimer's disease. Phytoestrogens have been proposed as potential alternatives to estrogen replacement therapy. The purpose of this study was to evaluate the in vitro protective effects of coumestrol on mice astrocytes.

Phytoestrogen consumption from foods and supplements and epithelial ovarian cancer risk: a population-based case control study.

Elisa V Bandera et al.

BMC women's health, 11, 40-40 (2011-09-29)

While there is extensive literature evaluating the impact of phytoestrogen consumption on breast cancer risk, its role on ovarian cancer has received little attention. We conducted a population-based case-control study to evaluate phytoestrogen intake from foods and supplements and epithelial

Quantification of five isoflavones and coumestrol in various solid agroenvironmental matrices using ¹³c₃-labeled internal standards.

Corinne C Hoerger et al.

Journal of agricultural and food chemistry, 59(3), 847-856 (2011-01-06)

We developed and validated three different sample preparation and extraction methods followed by HPLC-MS/MS (negative electrospray ionization) analysis for the quantification of estrogenic isoflavones (formononetin, daidzein, equol, biochanin A, and genistein) and coumestrol in red clover, soil, and manure. Plant

Mammographic breast density and serum phytoestrogen levels.

Sarah J Lowry et al.

Nutrition and cancer, 64(6), 783-789 (2012-08-07)

Some forms of estrogen are associated with breast cancer risk as well as with mammographic density (MD), a strong marker of breast cancer risk. Whether phytoestrogen intake affects breast density, however, remains unclear. We evaluated the association between serum levels
