What are you synching about? Emerging complexity of Notch signaling in the segmentation clock

Andrew Charles Oates, Olivier François Venzin

The Segmentation clock is a population of cellular genetic oscillators, located in the posterior of the elongating vertebrate embryo, that governs the rhythmic and sequential segmentation of the body axis into somites. Somites are blocks of cells that give ...

Empowering Global Chemical Biology at the Dawn of the New Decade

Yimon Aye

On January 22-24, 2020, scientific luminaries across the far-flung corners of chemical biology gathered in Geneva, Switzerland, to deliver their latest and greatest discoveries in the field. Generously supported by the Swiss National Science Foundation (SN ...

Notch Signaling - a Booster of Chronic Lymphocytic Leukemia During Initiation and Disease Progression

Delphine Maude Tardivon

Chronic lymphocytic leukemia (CLL) is a B cell malignancy and represents the most common leukemia in adults within the Western world. This disease mainly affects the elderly, with a median age of diagnosis over 70. The disease course is highly variable amo ...

Modeling metabolic and signaling pathways in cancer cells

Maria Masid Barcon

Cancer is a leading cause of death in the world, and the mechanisms that underlie this disease are still not completely understood. As cancer develops and progresses, cells undergo a diversity of mutations that sustain their rapid proliferation and the eva ...

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- ...

Quantitative relationships between SMAD dynamics and target gene activation kinetics in single live cells

Felix Naef, David Michael Suter, Torgil Elias Friman, Onur Tidin

The transduction of extracellular signals through signaling pathways that culminate in a transcriptional response is central to many biological processes. However, quantitative relationships between activities of signaling pathway components and transcript ...

Computational design of G Protein-Coupled Receptor allosteric signal transductions

Patrick Daniel Barth, Dániel Kéri

Membrane receptors sense and transduce extracellular stimuli into intracellular signaling responses but the molecular underpinnings remain poorly understood. We report a computational approach for designing protein allosteric signaling functions. By combin ...

Synaptic proximity enables NMDAR signalling to promote brain metastasis

Graham Knott, Douglas Hanahan, Mohammad Sadegh Saghafinia, Qiqun Zeng, Brian Donal McCabe, Wei Jiao, Inti Zlobec, Iacovos Michael, Giovanni Ciriello, Peng Zhang

Metastasis-the disseminated growth of tumours in distant organs-underlies cancer mortality. Breast-to-brain metastasis (B2BM) is a common and disruptive form of cancer and is prevalent in the aggressive basal-like subtype, but is also found at varying freq ...

Circadian rhythms and proteomics: It's all about posttranslational modifications!

Daniel Alain Dominique Marie Mauvoisin

The circadian clock is a molecular endogenous timekeeping system and allows organisms to adjust their physiology and behavior to the geophysical time. Organized hierarchically, the master clock in the suprachiasmatic nuclei, coordinates peripheral clocks, ...
