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

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 ...

Lanthanide-Based Peptide-Directed Visible/Near-Infrared Imaging and Inhibition of LMP1

Jean-Claude Bünzli, Yue Wu

A lanthanide-based peptide-directed bioprobe LnP19 (Ln = Eu or Yb) is designed as an impressive example of a small molecule-based dual-functional probe for the EBV oncoprotein LMP1. The peptide P19 (Pra-KAhx-K-LDLALK-FWLY-K-IVMSDKW-K-RrRK) is designed to s ...

A CMOS Image Sensor Pixel Combining Deep Sub-Electron Noise With Wide Dynamic Range

Christian Enz, Assim Boukhayma, Antonino Caizzone

This letter introduces a 5-transistors (5T) implementation of CMOS Image Sensors (CIS) pixels enabling the combination of deep sub-electronnoise performance with wide dynamic range (DR). The 5T pixel presents a new technique to reduce the sense node capaci ...

Augmented mitochondrial energy metabolism is an early response to chronic glucose stress in human pancreatic beta cells

Loïc Dayon, Andreas Wiederkehr, Sofia Moco, Isabelle Chareyron

Aims/hypothesis In islets from individuals with type 2 diabetes and in islets exposed to chronic elevated glucose, mitochondrial energy metabolism is impaired. Here, we studied early metabolic changes and mitochondrial adaptations in human beta cells durin ...

Mechanism and effects of pulsatile GABA secretion from cytosolic pools in the human beta cell

Steinunn Baekkeskov Hanahan, Chiara Cianciaruso, Petra Catalina Schwalie, Edward Allen Phelps

Pancreatic beta cells synthesize and secrete the neurotransmitter GABA (gamma-aminobutyric acid) as a paracrine and autocrine signal to help regulate hormone secretion and islet homeostasis. Islet GABA release has classically been described as a secretory- ...

Ovary-specific depletion of the nuclear receptor Nr5a2 compromises expansion of the cumulus oophorus but not fertilization by intracytoplasmic sperm injection

Kristina Schoonjans

The orphan nuclear receptor, liver receptor homolog-1 (aka Nuclear receptor subfamily 5, Group A, Member 2 (Nr5a2)), is widely expressed in mammalian tissues, and its ovarian expression is restricted to granulosa cells of activated follicles. We employed t ...

KAT2B Is Required for Pancreatic Beta Cell Adaptation to Metabolic Stress by Controlling the Unfolded Protein Response

Johan Auwerx, Hongbo Zhang

The endoplasmic reticulum (ER) unfolded protein response (UPR(er)) pathway plays an important role in helping pancreatic β cells to adapt their cellular responses to environmental cues and metabolic stress. Although altered UPR(er) gene expression appears ...

Anti-angiogenic properties of chlorambucil derivatives with fluorous and hydrocarbon appendages

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu

Chlorambucil (CLB) derivatives with long fluorous (referred to as 1 and 2) or hydrocarbon (3) chains have been evaluated in a series of in vitro and in vivo assays. In cell viability inhibition assays, both derivatives 2 and 3 show selective cytotoxicity t ...

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 ...

Murine ovarian follicle culture in PEG-hydrogel: Effects of mechanical properties and the hormones FSH and LH on development

Jeffrey Alan Hubbell, Seung Tae Lee, Jong Eun Ihm

The development of an in vitro culture system, comparable to the in vivo environment in terms of effects on oocyte growth and development, could provide a valuable experimental tool for studying the mechanisms governing oocyte development as well as practi ...

The Orphan Nuclear Receptor Nr5a2 Is Essential for Luteinization in the Female Mouse Ovary

Kristina Schoonjans

In the ovary, the follicular granulosa cells express the nuclear receptor Nr5a2 (nuclear receptor subfamily 5 group A member 2), also known as liver receptor homolog-1, and after ovulation, Nr5a2 expression persists in the corpus luteum. Previous studies d ...

Vertical cavity surface emitting laser cavity with low thermal impedance

Elyahou Kapon, Vladimir Iakovlev, Pascal Gallo

The present invention concerns new designs of VCLs with high contrast gratings (HCG) combined with diamond layer as a bottom mirror. They can be realized either with a classical V-shaped pumping scenario, or through the introduction of the pumping beam fro ...

Long-term doxycycline-regulated secretion of erythropoietin by encapsulated myoblasts

Patrick Aebischer, Bernard Schneider, Nicole Déglon

We developed an ex vivo gene therapy approach for the regulated delivery of therapeutic proteins based on the implantation of encapsulated, genetically engineered C(2)C(12) myoblasts. We investigated doxycycline-based regulation of gene expression to modul ...

Continuous delivery of human and mouse erythropoietin in mice by genetically engineered polymer encapsulated myoblasts

Patrick Aebischer, Nicole Déglon, Bernard Schneider

The transplantation of polymer encapsulated myoblasts genetically engineered to secrete erythropoietin (Epo) may obviate the need for repeated parenteral administration of recombinant Epo as a treatment for chronic renal failure, cancer or AIDS-associated ...
