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 ...

At the Intersection of Microbiota and Circadian Clock: Are Sexual Dimorphism and Growth Hormones the Missing Link to Pathology? Circadian Clock and Microbiota: Potential Egffect on Growth Hormone and Sexual Development

Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

Reciprocal interactions between the host circadian clock and the microbiota are evidenced by recent literature. Interestingly, dysregulation of either the circadian clock or microbiota is associated with common human pathologies such as obesity, type 2 dia ...

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 ...

The Mouse Microbiome Is Required for Sex-Specific Diurnal Rhythms of Gene Expression and Metabolism

Felix Naef, Cédric Gobet, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Jake Yeung

The circadian clock and associated feeding rhythms have a profound impact on metabolism and the gut microbiome. To what extent microbiota reciprocally affect daily rhythms of physiology in the host remains elusive. Here, we analyzed transcriptome and metab ...

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 ...

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 ...

Pancreatic α- and β-Cellular Clocks Have Distinct Molecular Properties and Impact on Islet Hormone Secretion and Gene Expression

Michaël Unser, Daniel Sage, Cédric Gobet, Frédéric Bruno Martin Gachon

A critical role of circadian oscillators in orchestrating insulin secretion and islet gene transcription has been demonstrated recently. However, these studies focused on whole islets and did not explore the interplay between α-cell and β-cell clocks. We p ...

Transforming Growth Factor beta/Activin signaling in neurons increases susceptibility to starvation

Bruno Lemaitre, Wen Bin Chng, Xiaoxue Li

Animals rely on complex signaling network to mobilize its energy stores during starvation. We have previously shown that the sugar-responsive TGF beta/Activin pathway, activated through the TGF beta ligand Dawdle, plays a central role in shaping the post-p ...

Systems Phytohormone Responses to Mitochondrial Proteotoxic Stress

Johan Auwerx, Xu Wang

Mitochondrial function is controlled by two separate genomes. This feature makes mitochondria prone to proteotoxic stress when a stoichiometric imbalance occurs in the protein complexes that perform oxidative phosphorylation, which consist of both nucleara ...

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, Valentina Scabia, Ayyakkannu Ayyanan, Rachel Marcone, Laura Battista, Maryse Fiche, 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 ...
