Circadian clock- and feeding-dependent regulation of translation initiation and elongation in the liver

Cédric Gobet

Circadian rhythms allow organisms to anticipate and adapt to periodic environmental changes related to the day-night cycle. These rhythms originate from a genetic network ticking in almost every cell of our body and the coordination between different organ ...

Erythrocyte's aging in microgravity highlights how environmental stimuli shape metabolism and morphology

Giovanni Dietler, Giovanni Longo

The determination of the function of cells in zero-gravity conditions is a subject of interest in many different research fields. Due to their metabolic unicity, the characterization of the behaviour of erythrocytes maintained in prolonged microgravity con ...

Code Generation in Computational Neuroscience: A Review of Tools and Techniques

Michael Lee Hines, Pramod Shivaji Kumbhar, Romain Brette

Advances in experimental techniques and computational power allowing researchers to gather anatomical and electrophysiological data at unprecedented levels of detail have fostered the development of increasingly complex models in computational neuroscience ...

Short-lived AUF1 p42-binding mRNAs of RANKL and BCL6 have two distinct instability elements each

Lukas Kühn, Giovanna Ambrosini, Philipp Bucher, Barbara Grisoni-Neupert, Ramona Pauchard-Batschulat, Otto Hagenbüchle

Regulation of mRNA stability by RNA-protein interactions contributes significantly to quantitative aspects of gene expression. We have identified potential mRNA targets of the AU-rich element binding protein AUF1. Myc-tagged AUF1 p42 was induced in mouse N ...

Chaperones convert the energy from ATP into the nonequilibrium stabilization of native proteins

Paolo De Los Rios, Alessandro Barducci, Pierre Goloubinoff, Bruno Claude Daniel Fauvet, Alberto Stefano Sassi

During and after protein translation, molecular chaperones require ATP hydrolysis to favor the native folding of their substrates and, under stress, to avoid aggregation and revert misfolding. Why do some chaperones need ATP, and what are the consequences ...

Ribosome profiling and dynamic regulation of translation in mammals

Felix Naef, Cédric Gobet

Protein synthesis is an energy-demanding cellular process. Consequently, a well-timed, fine-tuned and plastic regulation of translation is needed to adjust and maintain cell states under dynamically changing environments. Genome-wide monitoring of translat ...

Computational methods and modeling of cellular function for the optimization of protein production and the study of cellular disease states

Joana Raquel Pinto Vieira

Systems biology is a multidisciplinary field that weaves together all the basic sciences through the use of computational and bioinformatics tools, to provide a more integrative view of the complex molecular interactions taking place within and among cells ...

Enhancing mitochondrial proteostasis reduces amyloid-beta proteotoxicity

Johan Auwerx, Davide D'Amico, Adrian Schmid, Mario Romani, Norman Lionel Moullan, Vincenzo Sorrentino, Hongbo Zhang, Francesca Potenza, Solene Rietsch

Alzheimer's disease is a common and devastating disease characterized by aggregation of the amyloid-beta peptide. However, we know relatively little about the underlying molecular mechanisms or how to treat patients with Alzheimer's disease. Here we provid ...

Multi-omics analysis identifies ATF4 as a key regulator of the mitochondrial stress response in mammals

Johan Auwerx, Davide D'Amico

Mitochondrial stress activates a mitonuclear response to safeguard and repair mitochondrial function and to adapt cellular metabolism to stress. Using a multiomics approach in mammalian cells treated with four types of mitochondrial stressors, we identify ...

Genetic and epigenetic inactivation of SESTRIN1 controls mTORC1 and response to EZH2 inhibition in follicular lymphoma

Elisa Oricchio, Natalya Katanayeva, Elena Battistello, Maria Christine Donaldson, Stephanie Jocelyne Sungalee, Giovanni Ciriello

Follicular lymphoma (FL) is an incurable form of B cell lymphoma. Genomic studies have cataloged common genetic lesions in FL such as translocation t(14;18), frequent losses of chromosome 6q, and mutations in epigenetic regulators such as EZH2 Using a focu ...
