Headache in Pregnancy, the Puerperium, and menopause.

Semin Neurol 2018 Dec 6;38(6):627-633. Epub 2018 Dec 6.

Department of Neurology, University at Buffalo School of Medicine and Biomedical Sciences, The State University of New York, Buffalo, New York.

Headache is a neurologic disorder that displays gender dichotomy. It is well established that there is a strong link between migraine headache and sex hormones, specifically estrogen, which influences the severity of migraines during the menstrual cycle, pregnancy, and menopause. Furthermore, the epidemiology of headaches during pregnancy and the postpartum period is very distinct from that in males or nonpregnant females, in part due to the hemodynamic and hematologic changes that occur during pregnancy.

Bisphenol F causes disruption of gonadotropin-releasing hormone neural development in zebrafish via an estrogenic mechanism.

Neurotoxicology 2018 Dec 3. Epub 2018 Dec 3.

Department of Biology, Neuroscience Program, University of Puget Sound, Tacoma, Washington, USA. Electronic address:

Gonadotropin releasing hormone (GnRH) neurons in the brain are the main controllers of reproduction and reproductive behavior in most vertebrates, and are susceptible to endocrine disruption by different bisphenols. While the endocrine disrupting properties of bisphenol A have been well documented, commonly used analogues such as bisphenol F (BPF) are not as well studied. In this study we examined the effects of early, low-dose, chronic BPF exposure on the development of the GnRH neural system in the zebrafish embryo. Read More

Cardiovascular effects and molecular mechanisms of bisphenol A and its metabolite MBP in zebrafish.

Environ Sci Technol 2018 Dec 6. Epub 2018 Dec 6.

The plastic monomer bisphenol A (BPA) is one of the highest production volume chemicals in the world and is frequently detected in wildlife and humans, particularly children. BPA has been associated with numerous adverse health outcomes relating to its estrogenic and other hormonal properties, but direct causal links are unclear in humans and animal models. Here we simulated measured (1×) and predicted worst-case (10×) maximum foetal exposures for BPA, or equivalent concentrations of its metabolite MBP, using fluorescent reporter embryo-larval zebrafish capable of quantifying Estrogen Response Element (ERE) activation throughout the body.

Perfluorinated compounds binding to estrogen receptor of different species: a molecular dynamic modeling.

J Mol Model 2018 Dec 5;25(1). Epub 2018 Dec 5.

School of Pharmacy, Lanzhou University, Lanzhou, 730000, China.

Perfluorinated compounds (PFCs) were widely utilized in commercial and industrial applications, which could interfere with the endocrine systems of experimental animals and humans by interacting with estrogen receptors (ERs). Considering the possible differential binding preferences and relative binding affinities of PFCs to ERs of humans and other species, a cross-species comparison is necessary to effectively assess the health risk of PFCs to humans. In the present work, the species-specific binding characterizations between two PFCs, including perfluorooctane sulfonate (PFOS) and PFOS(4m, 5m), and the different ERαs from Rattus norvegicus, rainbow trout, and humans were explored based on a molecular dynamic modeling.

The evolving role of receptors as predictive biomarkers for metastatic breast cancer.

Expert Rev Anticancer Ther 2018 Dec 3:1-18. Epub 2018 Dec 3.

a Breast Cancer Now Edinburgh Team, Institute of Genetics and Molecular Medicine , University of Edinburgh, Western General Hospital , Edinburgh , UK.

Introduction: In breast cancer, estrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2) are essential biomarkers to predict response to endocrine and anti-HER2 therapies, respectively. In metastatic breast cancer, the use of these receptors and targeted therapies present additional challenges: temporal heterogeneity, together with limited sampling methodologies, hinders receptor status assessment, and the constant evolution of the disease invariably leads to resistance to treatment. Areas covered: This review summarizes the genomic abnormalities in ER and HER2, such as mutations, amplifications, translocations, and alternative splicing, emerging as novel biomarkers that provide an insight into underlying mechanisms of resistance and hold potential predictive value to inform treatment selection.

Gynecomastia is not uncommon in men older than 50 years of age and is characterized by glandular proliferation of breast tissue. Non-physiologic gynecomastia is mostly caused by a variety of external medical interventions. Medications that belong to classes of antiandrogens, antipsychotics, or antibiotics alter the levels of estrogen and testosterone and are commonly implicated in patients with gynecomastia. Read More

Dietary cadmium and risk of breast cancer subtypes defined by hormone receptor status: a prospective cohort study.

Int J Cancer 2018 Dec 4. Epub 2018 Dec 4.

Epidemiology and Prevention Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy.

Diet is the primary source of cadmium - a proven Group 1 human carcinogen - for non-smokers. Observational studies investigating the effect of cadmium from food sources on breast cancer risk have produced inconsistent results. We examined the association between dietary cadmium and risk of breast cancer defined by estrogen receptor (ER), progesterone receptor (PR) and HER2 status, in 8,924 women recruited to a prospective study between 1987 and 1992.

Colitis-induced colorectal cancer and intestinal epithelial estrogen receptor beta impact gut microbiota diversity.

Int J Cancer 2018 Dec 4. Epub 2018 Dec 4.

Department of Biosciences and Nutrition, Karolinska Institute, 141 57, Stockholm, Sweden.

Chronic inflammation of the colon (colitis) is a risk factor for colorectal cancer (CRC). Hormone-replacement therapy reduces CRC incidences, and the estrogen receptor beta (ERβ/ESR2) has been implicated in this protection. Gut microbiota is altered in both colitis and CRC and may influence the severity of both. Read More

Palbociclib in combination with letrozole in patients with estrogen receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer: PALOMA-2 subgroup analysis of Japanese patients.

Int J Clin Oncol 2018 Dec 4. Epub 2018 Dec 4.

Kyoto University Graduate School of Medicine, Kyoto, Japan.

Background: In PALOMA-2, palbociclib-letrozole significantly improved progression-free survival (PFS) vs placebo-letrozole in women with estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) advanced breast cancer (ABC) in the first-line setting. We evaluated the efficacy, safety, and pharmacokinetics of palbociclib in Japanese women in PALOMA-2.

Methods: In this phase 3 study, 666 postmenopausal women with ER+/HER2- ABC were randomized 2:1 to palbociclib (125 mg/day [3 weeks on/1 week off]) plus letrozole (2. Read More

Antigen Specificity and Clinical Significance of IgG and IgA Autoantibodies Produced by Tumor-Infiltrating B Cells in Breast Cancer.

Front Immunol 2018 20;9:2660. Epub 2018 Nov 20.

Cancer Biomarker and Immunotherapy Group, Latvian Biomedical Research and Study Centre, Riga, Latvia.

An important role for tumor infiltrating B lymphocytes (TIL-B) in the immune response to cancer is emerging; however, very little is known about the antigen specificity of antibodies produced . The presence of IgA antibodies in the tumor microenvironment has been noted although their biological functions and clinical significance are unknown. This study used a 91-antigen microarray to examine the IgG and IgA autoantibody repertoires in breast cancer (BC). Read More

mGluR5 Mediates Dihydrotestosterone-Induced Nucleus Accumbens Structural Plasticity, but Not Conditioned Reward.

Front Neurosci 2018 20;12:855. Epub 2018 Nov 20.

Graduate Program in Neuroscience, University of Minnesota, Minneapolis, MN, United States.

Gonadal hormones play a vital role in driving motivated behavior. They not only modulate responses to naturally rewarding stimuli, but also influence responses to drugs of abuse. A commonality between gonadal hormones and drugs of abuse is that they both impact the neurocircuitry of reward, including the regulation of structural plasticity in the nucleus accumbens (NAc).
