17β-Estradiol acts separately on the LDL particle and artery wall to reduce LDL accumulation

Journal of Lipid Research, 2000
Estrogen replacement therapy has been shown to attenuate atherogenesis, although the mechanisms for this effect are incompletely defined. Previously, we showed that 17-β estradiol (estradiol) attenuated oxidant stress-induced increases in vascular low ...

Efficacy of estradiol for the treatment of depressive disorders in perimenopausal women: a double-blind, randomized, placebo-controlled trial.

Archives of General Psychiatry, 2001
BACKGROUND Results of previous studies suggest that estrogen improves somatic and mild depressive symptoms experienced by perimenopausal women. This study investigated the efficacy of 17beta-estradiol for the treatment of clinically significant ...

Midlife Steroid‐Binding Globulin Levels and In Vivo Neuroimaging Measures of Tau in Older Men and Women

Annals of Neurology, EarlyView.
Objective In men and women, sex steroid hormones have been associated with increased risk of Alzheimer's disease (AD) dementia. We aimed to investigate the influence of midlife testosterone and sex hormone binding globulin (SHBG) levels on later‐life in vivo markers of β‐amyloid (Aβ) and tau deposition in clinically healthy older men. Methods This time‐

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

A two-step mechanism for the interaction of estradiol with rat uterus.

Proceedings of the National Academy of Sciences of the United States of America, 1968
During the past ten years much information has been accumulated concerning the interaction of tritilated estrogens with hormone-dependent tissues. Their striking affinity for estradiol, both in vivo'-5 and in vitro,6-9 first suggested that such target ...

μ‐Opioid Receptor Dynamics in the Parameningeal Tissue During Migraine Attacks

Annals of Neurology, EarlyView.
Objective The possible impact of meningeal μ‐opioid receptor (μOR) binding in migraine remains unknown. This study investigated μOR availability in the cranial parameninges involved in migraine initiation via nociceptor activation. Methods We used positron emission tomography with [11C] carfentanil, and measured μOR availability in meninges and ...

Investigating the KNDy hypothesis in humans by co-administration of kisspeptin, neurokinin B and naltrexone in men [PDF]

, 2016
Context: A subpopulation of hypothalamic neurons co-localise three neuropeptides namely kisspeptin, neurokinin B (NKB) and dynorphin collectively termed KNDy neurons. Animal studies suggest they interact to affect pulsatile GnRH release (KNDy hypothesis);

Sex Differences in Associations of Lewy Body Disease with Alzheimer's Disease and Cognitive Decline

Annals of Neurology, EarlyView.
Objective To investigate how sex and age at menopause influence the interplay between Alzheimer's disease (AD) and Lewy body disease (LBD) neuropathologies, and their associations with cognitive decline. Methods We analyzed data from: (1) three Rush Alzheimer's Disease Center cohorts (i.e., the Religious Orders Study, Rush Memory and Aging Project, and

Estrogen receptor-1 is a key regulator of HIV-1 latency that imparts gender-specific restrictions on the latent reservoir. [PDF]

, 2018
Unbiased shRNA library screens revealed that the estrogen receptor-1 (ESR-1) is a key factor regulating HIV-1 latency. In both Jurkat T cells and a Th17 primary cell model for HIV-1 latency, selective estrogen receptor modulators (SERMs, i.e ...
