Innovative Biomarkers for Obesity and Type 1 Diabetes Based on Bifidobacterium and Metabolomic Profiling

Stephan Morgenthaler, Paul Refinetti, Mariya Yuryevna Skvortsova

The role of Bifidobacterium species and microbial metabolites such as short-chain fatty acids (SCFAs) and human milk oligosaccharides in controlling intestinal inflammation and the pathogenesis of obesity and type 1 diabetes (T1D) has been largely studied ...

Generative machine learning produces kinetic models that accurately characterize intracellular metabolic states

Vassily Hatzimanikatis, Ljubisa Miskovic, Michaël Roger Germain Moret

Large omics datasets are nowadays routinely generated to provide insights into cellular processes. Nevertheless, making sense of omics data and determining intracellular metabolic states remains challenging. Kinetic models of metabolism are crucial for int ...

Inhibiting de novo ceramide synthesis restores mitochondrial and protein homeostasis in muscle aging

Johan Auwerx, Xiaoxu Li, Mario Romani, Tanes Imamura de Lima, Sandra Rodriguez Lopez, Jean-David Horacio Morel, Hao Li, Martin Rainer Wohlwend, Pirkka-Pekka Untamo Laurila, Ludger Jan Elzuë Goeminne, Barbara Moreira Crisol, Changmyung Oh, Dohyun Park

Disruption of mitochondrial function and protein homeostasis plays a central role in aging. However, how these processes interact and what governs their failure in aging remain poorly understood. Here, we showed that cer- amide biosynthesis controls the de ...

Reduced ech-6 expression attenuates fat-induced lifespan shortening in C. elegans

Richardus Houtkooper, Wen Gao, Yuan Liu

Deregulated energy homeostasis represents a hallmark of aging and results from complex gene-by-environment interactions. Here, we discovered that reducing the expression of the gene ech-6 encoding enoyl-CoA hydratase remitted fat diet-induced deleterious e ...

Microfluidic systems for in-flow bioanalytes collection

Pierre-Emmanuel Marie Thiriet

Microfluidic is an ensemble of technologies and methods that permits the handling and analysis of minute volumes of samples in short timescales. Since its introduction it revealed a remarkable potential to unveil novel biological mechanisms. The small volu ...

Single-cell lipidomics reveals a role for cell-to-cell sphingolipid heterogeneity in fibroblast activation

Laura Capolupo

Cell-to-cell variability plays a key role in tissue patterning by setting initial asymmetry that primes cell fate decisions. Fluctuations in the activity of regulatory molecules can commit individual cells to divergent differentiation pathways, and cell-to ...

Accelerating photofragmentation UV Spectroscopy–Mass spectrometry fingerprinting for quantification of isomeric peptides

Oleg Boyarkine, Elizaveta Solovyeva, Erik Saparbayev

Identification of isomeric biomolecules remains a challenging analytical problem. A recently developed spectroscopic method that combines UV photofragmentation and mass spectrometry for fingerprinting of cold ions (2D UV-MS), has already demonstrated its h ...

Organohalide respiration: variations on a common theme

Christof Holliger, Julien Maillard, Mathilde Stéphanie Willemin, Lorenzo Cimmino

Organohalide respiration (OHR) is a bacterial anaerobic respiratory metabolism that makes use of halogenated organic compounds as terminal electron acceptors. While organohalogens have been initially thought to be mainly from anthropogenic origin, thousand ...

Metabolic and transcriptomic profiles of glioblastoma invasion revealed by comparisons between patients and corresponding orthotopic xenografts in mice

Lijing Xin, Cristina Ramona Cudalbu, Mario Gaetano Lepore, Marta Lai

The invasive behavior of glioblastoma, the most aggressive primary brain tumor, is considered highly relevant for tumor recurrence. However, the invasion zone is difficult to visualize by Magnetic Resonance Imaging (MRI) and is protected by the blood brain ...

redLips: a comprehensive mechanistic model of the lipid metabolic network of yeast

Vassily Hatzimanikatis, Sofia Tsouka

Over the last decades, yeast has become a key model organism for the study of lipid biochemistry. Because the regulation of lipids has been closely linked to various physiopathologies, the study of these biomolecules could lead to new diagnostics and treat ...
