Proteomics reveals unique plasma signatures in constitutional thinness

Loïc Dayon, Jörg Hager, Nele Gheldof

Purpose Studying the plasma proteome of control versus constitutionally thin (CT) individuals, exposed to overfeeding, may give insights into weight-gain management, providing relevant information to the clinical entity of weight-gain resistant CT, and dis ...

Cerebrospinal Fluid Proteome Alterations Associated with Neuropsychiatric Symptoms in Cognitive Decline and Alzheimer's Disease

Loïc Dayon

Although neuropsychiatric symptoms (NPS) are common and severely affect older people with cognitive decline, little is known about their underlying molecular mechanisms and relationships with Alzheimer's disease (AD). The aim of this study was to identify ...

Blood plasma protein profiles of neuropsychiatric symptoms and related cognitive decline in older people

Loïc Dayon

Neuropsychiatric symptoms (NPS) severely affect patients and their caregivers, and are associated with worse long-term outcomes. This study tested the hypothesis that altered protein levels in blood plasma could serve as biomarkers of NPS; and that altered ...

Proteomics of Human Milk: Definition of a Discovery Workflow for Clinical Research Studies

Loïc Dayon

Milk is a complex biological fluid composed mainly of water, carbohydrates, lipids, proteins, and diverse bioactive factors. Human milk represents a unique tailored source of nutrients that adapts during lactation to the specific needs of the developing in ...

Crosstalk between Drp1 phosphorylation sites during mitochondrial remodeling and their impact on metabolic adaptation

Carlos Canto Alvarez, Loïc Dayon

Mitochondria constantly undergo fusion and fission events, referred as mitochondrial dynamics, which determine mitochondrial architecture and bioenergetics. Cultured cell studies demonstrate that mitochondrial dynamics are acutely regulated by phosphorylat ...

Exploration of human cerebrospinal fluid: A large proteome dataset revealed by trapped ion mobility time-of-flight mass spectrometry

Loïc Dayon

Cerebrospinal fluid (CSF) is a biofluid in direct contact with the brain and as such constitutes a sample of choice in neu-rological disorder research, including neurodegenerative dis-eases such as Alzheimer or Parkinson. Human CSF has still been less stud ...

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 ...

Progress and pitfalls of using isobaric mass tags for proteome profiling

Loïc Dayon

Introduction: Quantitative proteomics using mass spectrometry is performed via label-free or label-based approaches. Labeling strategies rely on the incorporation of stable heavy isotopes by metabolic, enzymatic, or chemical routes. Isobaric labeling uses ...

Nuclear Proteomics Uncovers Diurnal Regulatory Landscapes in Mouse Liver

Felix Naef, Loïc Dayon, Jingkui Wang, Frédéric Bruno Martin Gachon, Martin Kussmann, Daniel Alain Dominique Marie Mauvoisin, Florian Atger, Federico Sizzano

Diurnal oscillations of gene expression controlled by the circadian clock and its connected feeding rhythm enable organisms to coordinate their physiologies with daily environmental cycles. While available techniques yielded crucial insights into regulatio ...

Circadian and Feeding Rhythms Orchestrate the Diurnal Liver Acetylome

Felix Naef, Carlos Canto Alvarez, Jingkui Wang, Loïc Dayon, Frédéric Bruno Martin Gachon, Martin Kussmann, Daniel Alain Dominique Marie Mauvoisin, Joanna Ratajczak, Sebastiano Collino, Florian Atger

Lysine acetylation is involved in various biological processes and is considered a key reversible post-translational modification in the regulation of gene expression, enzyme activity, and subcellular localization. This post-translational modification is t ...
