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 ...

Association between endocrine adjuvant therapy intake timing and disease-free survival in patients with high-risk early breast cancer: results of a sub-study of the UCBG- UNIRAD trial

Elise Hélène Dumas

Background Circadian rhythms regulate cellular physiology and could in fl uence the ef fi cacy of endocrine therapy (ET) in breast cancer (BC). We prospectively tested this hypothesis within the UNIRAD adjuvant phase III trial (NCT01805271). Methods 1278 p ...

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 ...

Role of the androgen receptor in the human breast epithelium

Fabio De Martino

Breast cancer is the most common malignancy in women worldwide and understanding the risk factors affecting it is key for prevention. The relative risk of developing breast cancer is related to exposure to both endogenous hormones and exogenous natural and ...

A high resolution LC-MS targeted method for the concomitant analysis of 11 contraceptive progestins and 4 steroids

Cathrin Brisken, Marc Moniatte, Jonathan Paz Montoya, Fabio De Martino, Marie Shamseddin, Csaba Ferenc László

In the context of hormonal contraception and hormone replacement therapy (HRT), many women are exposed to exogenous hormones. Current use of hormonal contraception with combined ethinyl estradiol and different progestins bestows a breast cancer relative ri ...

Risk prediction of developing venous thrombosis in combined oral contraceptive users

Emmanuelle Logette, Valérie Buchillier

Background Venous thromboembolism (VTE) is a complex multifactorial disease influenced by genetic and environmental risk factors. An example for the latter is the regular use of combined oral contraceptives (CC), which increases the risk to develop VTE by ...

Rapid Production of Submicron Drug Substance Particles by Supersonic Spray Drying

Esther Amstad

Many newly developed active pharmaceutical ingredients (APIs) are poorly soluble in water and thus have a dissolution-limited bioavailability. The bioavailability of Biopharmaceutical Classification System (BCS) class II APIs increases if they dissolve fas ...

Polyphenic trait promotes liver cancer in a model of epigenetic instability

Didier Trono, Sandra Eloise Kjeldsen, Alessandra Piersigilli, Evaristo Jose Planet Letschert, Marco Cassano, Suk Min Jang

Hepatocellular carcinoma (HCC) represents the fifth most common form of cancer worldwide and carries a high mortality rate due to lack of effective treatment. Males are eight times more likely to develop HCC than females, an effect largely driven by sex ho ...

Functional genomics of corrinoid starvation in the organohalide-respiring bacterium Dehalobacter restrictus strain PER-K23

Christof Holliger, Julien Maillard, Yue Lu, Hauke Smidt, Aamani Rupakula Boyanapalli

De novo comnoid biosynthesis represents one of the most complicated metabolic pathways in nature. Organohalide-respiring bacteria (OHRB) have developed different strategies to deal with their need of corrinoid, as it is an essential cofactor of reductive d ...

Monitoring proliferative activities of hormone-like odorants in human breast cancer cells by gene transcription profiling and electrical impedance spectroscopy

Horst Arthur Vogel, Cathrin Brisken, Horst Pick, Samuel Terrettaz, Olivia Baud

The human estrogen receptor alpha (ER!) mediates the proliferative action of hormones in breast cancer cells by regulating the expression of target genes to control cellular functions. Current methodologies do not permit a real-time assessment of these pro ...

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 ...

Probing Odorant-Mediated Receptor Activation

Olivia Baud

Molecular interactions of odorants with their olfactory receptors (ORs) are of central importance for the mammalian olfactory system to detect and discriminate a large variety of odors with a limited set of receptors. How a particular OR binds and distingu ...

Amphiregulin mediates self-renewal in an immortal mammary epithelial cell line with stem cell characteristics

Cathrin Brisken, Lucia Jimenez Rojo

Amphiregulin (AREG), a ligand for epidermal growth factor receptor, is required for mammary gland ductal morphogenesis and mediates estrogen actions in vivo, emerging as an essential growth factor during mammary gland growth and differentiation. The COMMA- ...

The orphan nuclear receptor small heterodimer partner mediates male infertility induced by diethylstilbestrol in mice

Johan Auwerx, Kristina Schoonjans

Studies in rodents have shown that male sexual function can be disrupted by fetal or neonatal administration of compounds that alter endocrine homeostasis, such as the synthetic nonsteroidal estrogen diethylstilbestrol (DES). Although the molecular basis f ...

c-Myc and its target FoxM1 are critical downstream effectors of constitutive androstane receptor (CAR) mediated direct liver hyperplasia

Sandra Eloise Kjeldsen, Christelle Dubey

In the adult liver, 1,4-bis[2-(3,5-dichloropyridyloxy)] benzene (TCPOBOP), an agonist of the constitutive androstane receptor (CAR, NR1I3), produces rapid hepatomegaly in the absence of injury. In this study, we identify c-Myc as a gene induced by CAR and ...

Hydroxylated Metabolites of β- and δ-Hexachlorocyclohexane: Bacterial Formation, Stereochemical Configuration, and Occurrence in Groundwater at a Former Production Site

Christof Holliger

Estrogenic substances discharged from wastewater treatment plants have been detected in surface sediments of receiving waters, but little is known of their vertical migration through buried sediments and their potential to contaminate subsurface waters. Th ...

In vivo investigation of estrogenic activity by fluorescence techniques

Hanna Jankevics

Hormone binding nuclear receptors are transcription factors that activate gene transcription by binding to specific DNA sequences in the gene promoter region and then recruiting the necessary coactivator proteins for transcriptional activation. The knowled ...
