Study of Immobilization Procedure on Silver Nanolayers and Detection of Estrone with Diverged Beam Surface Plasmon Resonance (SPR) Imaging [PDF]

open access: goldBiosensors, 2013
An immobilization protocol was developed to attach receptors on smooth silver thin films. Dense and packed 11-mercaptoundecanoic acid (11-MUA) was used to avoid uncontrolled sulfidization and harmful oxidation of silver nanolayers.

The contribution of 17beta-hydroxysteroid dehydrogenase type 1 to the estradiol-estrone ratio in estrogen-sensitive breast cancer cells. [PDF]

open access: yesPLoS ONE, 2012
Estrone and estradiol are both estrogens with estrone being the less potent form and estradiol being the most potent estrogen. The binding of the latter to cellular regulatory elements stimulates the proliferation of breast cancer cells.

A Receptor-Independent Effect of Estrone Sulfate on the hERG Channel

open access: bronzeJournal of Pharmacological Sciences, 2009
We recently reported that physiological concentrations of 17β-estradiol partially down-regulate cardiac rapidly-activating delayed rectifier K+ currents (hERG currents) independently of estrogen-receptor signaling.

Long-Term Prospective Study of the Influence of Estrone Levels on Events in Postmenopausal Women with or at High Risk for Coronary Artery Disease

open access: yesThe Scientific World Journal, 2012
Background. The link between endogenous estrogen, coronary artery disease (CAD), and death in postmenopausal women is uncertain. We analyzed the association between death and blood levels of estrone in postmenopausal women with known coronary artery ...

A MALDI-MS-based quantitative analytical method for endogenous estrone in human breast cancer cells [PDF]

open access: goldScientific Reports, 2016
The level of endogenous estrone, one of the three major naturally occurring estrogens, has a significant correlation with the incidence of post-menopausal breast cancer.

Sex and reproductive stage modify the effect of endogenous oestrogens on coronary atherosclerosis in rheumatoid arthritis [PDF]

open access: yesRMD Open
Objective We explored associations between endogenous oestrogens, coronary atherosclerosis and cardiovascular risk in rheumatoid arthritis (RA). We interrogated whether these relationships varied by sex and menopause and reflected differences in ...

TiO2-assisted photocatalytic degradation of diclofenac, metoprolol, estrone and chloramphenicol as endocrine disruptors in water [PDF]

open access: hybridAdsorption, 2013
The photocatalytic oxidation of diclofenac, metoprolol, estrone and chloramphenicol was tested in the tube reactor using different commercially available TiO2. The photocatalysts were characterized using BET, XRD and SEM.

Estrogen associations with human pregnancy related increases in cytochrome P450 3A activity [PDF]

open access: yesFrontiers in Pharmacology
IntroductionIncreased CYP3A-mediated drug clearance during pregnancy can lead to subtherapeutic dosing of CYP3A substrates. Pregnancy-related hormones (PRHs) increase CYP3A4 expression and activity in cultured human hepatocytes.

Urinary Glyphosate Concentrations and Serum Sex Hormones in a Nationally Representative U.S. Sample: NHANES 2017–2018 [PDF]

open access: yesLife
Glyphosate and glyphosate-based herbicides (GBHS) are the most widely used herbicides worldwide, yet their potential endocrine-disrupting effects in humans remain inadequately studied.
