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

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 ...

Estrogen receptor signaling in the human breast epithelium

Céline Berthe Constantin

Breast cancer is the most diagnosed malignancy in women worldwide, making effective prevention strategies crucial. Hormonal contraceptives, consisting of a synthetic progesterone receptor agonist alone or in combination with an estrogen, are used by millio ...

Epigenetic remodelling of enhancers in response to estrogen deprivation and re-stimulation

Ludovica Vanzan

Estrogen hormones are implicated in a majority of breast cancers and estrogen receptor alpha (ER), the main nuclear factor mediating estrogen signaling, orchestrates a complex molecular circuitry that is not yet fully elucidated. Here, we investigated geno ...

The Contorsbody, an antibody format for agonism: design, structure, and function

Henning Paul-Julius Stahlberg

The careful design of the antibody architecture is becoming more and more important, especially when the purpose is agonism. We present the design of a novel antibody format that is able to promote receptor dimerization and induce signal transduction resul ...

90 YEARS OF PROGESTERONE Progesterone receptor signaling in the normal breast and its implications for cancer

Cathrin Brisken, Valentina Scabia

Progesterone is considered as the pregnancy hormone and acts on many different target tissues. Progesterone receptor (PR) signaling is important for normal development and the physiologic function of the breast and impinges on breast carcinogenesis. Both s ...

Influenza A viruses use multivalent sialic acid clusters for cell binding and receptor activation

Suliana Manley, Christian Sieben

Influenza A virus (IAV) binds its host cell using the major viral surface protein hemagglutinin (HA). HA recognizes sialic acid, a plasma membrane glycan that functions as the specific primary attachment factor (AF). Since sialic acid alone cannot fulfill ...

Membrane expression of the estrogen receptor ER alpha is required for intercellular communications in the mammary epithelium

Cathrin Brisken, Stéphanie Cagnet

17 beta-Estradiol induces the postnatal development of mammary gland and influences breast carcinogenesis by binding to the estrogen receptor ER alpha. ER alpha acts as a transcription factor but also elicits rapid signaling through a fraction of ER alpha ...

Hormone receptor signaling in estrogen receptor positive breast cancer

Valentina Scabia

Estrogen receptor (ER) and progesterone receptor (PR) signaling tightly interact in controlling postnatal breast development and impinge on breast carcinogenesis. PR is a direct transcriptional target of ER signaling and ER and PR bind closely to DNA and i ...

Assessment of early response biomarkers in relation to long-term survival in patients with HER2-negative breast cancer receiving neoadjuvant chemotherapy plus bevacizumab: Results from the Phase II PROMIX trial

Eric Paquet

Pathologic complete response (pCR) is a predictor for favorable outcome after neoadjuvant treatment in early breast cancer. Modulation of gene expression may also provide early readouts of biological activity and prognosis, offering the possibility for tim ...

Dual optical control and mechanistic insights into photoswitchable group II and III metabotropic glutamate receptors

Johannes Broichhagen

G protein-coupled receptor (GPCR) signaling occurs in complex spatiotemporal patterns that are difficult to probe using standard pharmacological and genetic approaches. A powerful approach for dissecting GPCRs is to use light-controlled pharmacological age ...

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 ...

Effects of clofibric acid alone and in combination with 17 beta-estradiol on mRNA abundance in primary hepatocytes isolated from rainbow trout

Kristin Schirmer

Clofibric acid (CA) is the active substance of lipid lowering drugs. It is resistant to degradation, polar in nature, and has been found ubiquitously in the aquatic environment. Though CA is classified as a peroxisomal proliferator in rodents and is consid ...

Longitudinal neurochemical modifications in the aging mouse brain measured in vivo by 1H magnetic resonance spectroscopy

João Miguel das Neves Duarte, Rolf Gruetter

Alterations to brain homeostasis during development are reflected in the neurochemical profile determined noninvasively by (1)H magnetic resonance spectroscopy. We determined longitudinal biochemical modifications in the cortex, hippocampus, and striatum o ...

Bile Acids Alter Male Fertility Through G-Protein-Coupled Bile Acid Receptor 1 Signaling Pathways in Mice

Kristina Schoonjans

Bile acids (BAs) are signaling molecules that are involved in many physiological functions, such as glucose and energy metabolism. These effects are mediated through activation of the nuclear and membrane receptors, farnesoid X receptor (FXR-alpha) and TGR ...

Impact of environmental estrogens on fish considering the diversity of estrogen signaling

Research on endocrine disruption in fish has been dominated by studies on estrogen-active compounds which act as mimics of the natural estrogen, 17 beta-estradiol (E2), and generally exert their biological actions by binding to and activation of estrogen r ...

ER and PR signaling nodes during mammary gland development

Cathrin Brisken, Tamara Tanos, Lucia Jimenez Rojo

The ovarian hormones estrogen and progesterone orchestrate postnatal mammary gland development and are implicated in breast cancer. Most of our understanding of the molecular mechanisms of estrogen receptor (ER) and progesterone receptor (PR) signaling ste ...

A Biochemical and Biophysical Investigation of 5-HT3 Receptor Stability

Menno Berend Tol

The 5-hydroxytryptamine 3 receptor (5-HT3R) is a member of the pentameric ligand-gated ion channel (pLGIC) family, that plays an important role in fast signal transduction and cell-cell communication in synapses: They convert a chemical signal from a neuro ...

Epigenetic Modification of the FMR1 Gene in Fragile X Syndrome Is Associated with Differential Response to the mGluR5 Antagonist AFQ056

Nouchine Hadjikhani, Fei Chen

Fragile X syndrome (FXS) is an X-linked condition associated with intellectual disability and behavioral problems. It is caused by expansion of a CGG repeat in the 5' untranslated region of the fragile X mental retardation 1 (FMR1) gene. This mutation is a ...
