Androgen Receptor Signaling in in vivo models of Estrogen Receptor-positive Breast Cancer and Normal Breast Epithelium

Andrea Agnoletto

Steroid hormone receptors (HRs) are ligand-activated transcription factors that play a pivotal role in breast development and carcinogenesis. It is well established that estrogen receptor (ER) signaling is a major proliferative driver in estrogen receptor ...

Plant sterols and cholesterol metabolism are associated with five-year cognitive decline in the elderly population

Mehdi Gholam, Christopher Clark

Dysregulations in cholesterol metabolism are associated with neurodegenerative and vascular pathologies, and dementia. Diet-derived plant sterols (phytosterols) have cholesterol-lowering, anti-inflammatory, and antioxidant properties and may interfere with ...

Synchronous nonmonotonic changes in functional connectivity and white matter integrity in a rat model of sporadic Alzheimer's disease

Bernard Lanz, Carole Poitry-Yamate, Katarzyna Pierzchala, Ileana Ozana Jelescu, Ting Yin, Yujian Diao

Brain glucose hypometabolism has been singled out as an important contributor and possibly main trigger to Alzheimer's disease (AD). Intracerebroventricular injections of streptozotocin (icv-STZ) cause brain glucose hypometabolism without systemic diabetes ...

Stress, glucocorticoid receptor and social behaviors

Aurélie Lattion

Peripuberty, comprising childhood and adolescence, constitutes an important time window in the brain development and maturation. Exposure to prolonged stress during this period has been shown to increase the risk for the development of psychopathologies la ...

Bile acid-FXR alpha pathways regulate male sexual maturation in mice

Kristina Schoonjans

The bile acid receptor Farnesol-X-Receptor alpha (FRX alpha) is a member of the nuclear receptor superfamily. FRX alpha is expressed in the interstitial compartment of the adult testes, which contain the Leydig cells. In adult, short term treatment (12 hou ...

A Preclinical Model for ERα-Positive Breast Cancer Points to the Epithelial Microenvironment as Determinant of Luminal Phenotype and Hormone Response

Cathrin Brisken, Georgios Sflomos, Ayyakkannu Ayyanan, Valentina Scabia, Rachel Marcone, Laura Battista, Valérian Charles Robert Dormoy

Seventy-five percent of breast cancers are estrogen receptor α positive (ER(+)). Research on these tumors is hampered by lack of adequate in vivo models; cell line xenografts require non-physiological hormone supplements, and patient-derived xenografts (PD ...

Proteome-Wide Effect of 17-beta-Estradiol and Lipoxin A(4) in an Endometriotic Epithelial Cell Line

Endometriosis affects approximately 10% of women of reproductive age. This chronic, gynecological inflammatory disease results in a decreased quality of life for patients, with the main symptoms including chronic pelvic pain and infertility. The steroid ho ...

Leader corruption depends on power and testosterone

Samuel Bendahan

We used incentivized experimental games to manipulate leader power - the number of followers and the discretion leaders had to enforce their will. Leaders had complete autonomy in deciding payouts to themselves and their followers. Although leaders could m ...

Identification of the Link Between the Hypothalamo-Pituitary Axis and the Testicular Orphan Nuclear Receptor NR0B2 in Adult Male Mice

Kristina Schoonjans

The small heterodimer partner (SHP, nuclear receptor subfamily 0, group B, member 2; NR0B2) is an atypical nuclear receptor known mainly for its role in bile acid homeostasis in the enterohepatic tract. We previously showed that NR0B2 controls testicular f ...

Concentration-dependent and surface-assisted self-assembly properties of a bioactive estrogen receptor alpha-derived peptide

Giovanni Dietler, Francesco Simone Ruggeri

We have synthesized a 17-mer peptide (ER17p) that is issued from the hinge region of the estrogen receptor and which activates the proliferation of breast carcinoma cells in steroid-deprived conditions. In the present paper, we show that at a concentration ...

The Glucocorticoid-Induced Leucine Zipper (Gilz/Tsc22d3-2) Gene Locus Plays a Crucial Role in Male Fertility

Jian Wang, Friedrich Beermann, Roman Chrast

The glucocorticoid-induced leucine zipper (Tsc22d3-2) is a widely expressed dexamethasone-induced transcript that has been proposed to be important in immunity, adipogenesis, and renal sodium handling based on in vitro studies. To address its function in v ...

Stress during puberty boosts metabolic activation associated with fear-extinction learning in hippocampus, basal amygdala and cingulate cortex

Maria del Carmen Sandi Perez

Adolescence is characterized by major developmental changes that may render the individual vulnerable to stress and the development of psychopathologies in a sex-specific manner. Earlier we reported lower anxiety-like behavior and higher risk-taking and no ...
