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 ...

Cryo-EM structure of native human thyroglobulin

Henning Paul-Julius Stahlberg

The thyroglobulin (TG) protein is essential to thyroid hormone synthesis, plays a vital role in the regulation of metabolism, development and growth and serves as intraglandular iodine storage. Its architecture is conserved among vertebrates. Synthesis of ...

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 ...

The secreted protease Adamts18 links hormone action to activation of the mammary stem cell niche

Cathrin Brisken, Giovanna Ambrosini, Marian Caikovski, Dalya Ataca, Philipp Bucher, Renuga Devi Rajaram, Patrik Aouad, Marie Shamseddin, Céline Berthe Constantin, Csaba Ferenc László, Rachel Marcone

Estrogens and progesterone control breast development and carcinogenesis via their cognate receptors expressed in a subset of luminal cells in the mammary epithelium. How they control the extracellular matrix, important to breast physiology and tumorigenes ...

Gender medicine and oncology: report and consensus of an ESMO workshop

Jacques Fellay

Background: The importance of sex and gender as modulators of disease biology and treatment outcomes is well known in other disciplines of medicine, such as cardiology, but remains an undervalued issue in oncology. Considering the increasing evidence for t ...

C/EBP alpha mediates the growth inhibitory effect of progestins on breast cancer cells

Cathrin Brisken, Valentina Scabia

Steroid hormones are key gene regulators in breast cancer cells. While estrogens stimulate cell proliferation, progestins activate a single cell cycle followed by proliferation arrest. Here, we use biochemical and genome-wide approaches to show that proges ...

Modular Total Synthesis and Cell-Based Anticancer Activity Evaluation of Ouabagenin and Other Cardiotonic Steroids with Varying Degrees of Oxygenation

Yimon Aye

A Cu(II)-catalyzed diastereoselective Michael/aldol cascade approach is used to accomplish concise total syntheses of cardiotonic steroids with varying degrees of oxygenation including cardenolides ouabagenin, sarmentologenin, 19-hydroxysarmentogenin, and ...

What is the 'spectral diet' of humans?

Marilyne Andersen, Forrest Simon Webler, Manuel Spitschan

Our visual perception of the world - seeing form and colour or navigating the environment - depends on the interaction of light and matter in the environment. Light also has a more fundamental role in regulating rhythms in physiology and behaviour, as well ...

Progestins used for hormonal contraception in Switzerland: study of their effects on the breast epithelium

Marie Shamseddin

Breast cancer is the most commonly diagnosed cancer and the most common cause of cancer death among women. Hormones have been shown to have a key role in breast development and carcinogenesis. Repeated activation of progesterone receptor (PR) signaling as ...

An energetic view of stress: Focus on mitochondria

Maria del Carmen Sandi Perez

Energy is required to sustain life and enable stress adaptation. At the cellular level, energy is largely derived from mitochondria – unique multifunctional organelles with their own genome. Four main elements connect mitochondria to stress: 1) Energy is r ...

Novel compartment-specific biosensors reveal a complementary subcellular distribution of bioactive Furin and PC7

Pierpaolo Ginefra

Proprotein Convertases (PCs) constitute a family of serine proteases that activate various hormones, growth factors and cell adhesion molecules by mediating endoproteolytic cleavage of their secreted inactive precursors during their transit in the secret ...

Polyphenic trait promotes liver cancer in a model of epigenetic instability

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

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 ...

Extensive Regulation of Diurnal Transcription and Metabolism by Glucocorticoids

Cédric Gobet, Meltem Weger, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

Altered daily patterns of hormone action are suspected to contribute to metabolic disease. It is poorly understood how the adrenal glucocorticoid hormones contribute to the coordination of daily global patterns of transcription and metabolism. Here, we exa ...

No Scope for Social Modulation of Steroid Levels in a Year-Round Territorial Damselfish

Katarina Damjanovic

Both latitude and mating system have been proposed to shape relationships between steroid hormone levels and social behavior. Recently it has been postulated that species with long lasting non-seasonal territorial behavior have low androgen responsiveness. ...

Endocrine hormones and local signals during the development of the mouse mammary gland

Cathrin Brisken, Dalya Ataca

Most of mammary gland development occurs postnatally under the control of female reproductive hormones, which in turn interact with other endocrine factors. While hormones impinge on many tissues and trigger very complex biological responses, tissue recomb ...

Progesterone/RANKL Is a Major Regulatory Axis in the Human Breast

Cathrin Brisken, Tamara Tanos, Georgios Sflomos, Ayyakkannu Ayyanan, Maryse Fiche, Maria Gutierrez Najera

Estrogens and progesterones are major drivers of breast development but also promote carcinogenesis in this organ. Yet, their respective roles and the mechanisms underlying their action in the human breast are unclear. Receptor activator of nuclear factor ...

Liver receptor homolog-1 is essential for pregnancy

Kristina Schoonjans

Successful pregnancy requires coordination of an array of signals and factors from multiple tissues. One such element, liver receptor homolog-1 (Lrh-1), is an orphan nuclear receptor that regulates metabolism and hormone synthesis(1). It is strongly expres ...
