The Polyglutamine Expansion at the N-Terminal of Huntingtin Protein Modulates the Dynamic Configuration and Phosphorylation of the C-Terminal HEAT Domain

Ruedi Aebersold, Matteo Dal Peraro, Giorgio Elikem Tamo, Maria Josefina Marcaida Lopez

The polyQ expansion in huntingtin protein (HTT) is the prime cause of Huntington's disease (HD). The recent cryoelectron microscopy (cryo-EM) structure of HTT-HAP40 complex provided the structural information on its HEAT-repeat domains. Here, we present an ...

A new class of protein biomarkers based on subcellular distribution: application to a mouse liver cancer model

Ruedi Aebersold, Kristina Schoonjans, Evan Graehl Williams, Pan Xu, Amir Banaei Esfahani, Vera Monica Lemos Da Silva, Chen Li

To-date, most proteomic studies aimed at discovering tissue-based cancer biomarkers have compared the quantity of selected proteins between case and control groups. However, proteins generally function in association with other proteins to form modules loc ...

The interactome of KRAB zinc finger proteins reveals the evolutionary history of their functional diversification

Didier Trono, Priscilla Turelli, Ruedi Aebersold, Julien Léonard Duc, Michaël Imbeault, Cécile Piot, Andrea Coluccio, Pierre-Yves Joseph Laurent Helleboid, Christian Axel Wandall Thorball, Julien Paul André Pontis

Krüppel‐associated box (KRAB)‐containing zinc finger proteins (KZFPs) are encoded in the hundreds by the genomes of higher vertebrates, and many act with the heterochromatin‐inducing KAP1 as repressors of transposable elements (TEs) during early embryogene ...

Quantifying and Localizing the Mitochondrial Proteome Across Five Tissues in A Mouse Population

Ruedi Aebersold, Johan Auwerx, Evan Graehl Williams, Dongryeol Ryu, Pooja Jha, Jiayi Lan, Jun Yong Kim, Moaraj Hasan

We have used SWATH mass spectrometry to quantify 3648 proteins across 76 proteomes collected from genetically diverse BXD mouse strains in two fractions (mitochondria and total cell) from five tissues: liver, quadriceps, heart, brain, and brown adipose (BA ...

NAD+ repletion improves mitochondrial and stem cell function and enhances life span in mice

Matthias Lütolf, Ruedi Aebersold, Kristina Schoonjans, Johan Auwerx, Dongryeol Ryu, Hongbo Zhang, Keir Joe Menzies, Karim Laurent Gariani, Xu Wang, Peiling Luan, Davide D'Amico

Adult stem cells (SCs) are essential for tissue maintenance and regeneration yet are susceptible to senescence during aging. We demonstrate the importance of the amount of the oxidized form of cellular nicotinamide adenine dinucleotide (NAD(+)) and its imp ...

Systems proteomics of liver mitochondria function

Sébastien Dubuis, Ruedi Aebersold, Johan Auwerx, Evan Graehl Williams, Tiffany Amariuta, Pooja Jha

Recent improvements in quantitative proteomics approaches, including Sequential Window Acquisition of all Theoretical Mass Spectra (SWATH-MS), permit reproducible large-scale protein measurements across diverse cohorts. Together with genomics, transcriptom ...

Multilayered genetic and omics dissection of mitochondrial activity in a mouse reference population

Sébastien Dubuis, Ruedi Aebersold, Johan Auwerx, Evan Graehl Williams, Adrienne Joëlle Laurence Mottis, Virginija Jovaisaite

The manner by which genotype and environment affect complex phenotypes is one of the fundamental questions in biology. In this study, we quantified the transcriptome--a subset of the metabolome--and, using targeted proteomics, quantified a subset of the li ...

The Biology/Disease-driven Human Proteome Project (B/D-HPP): Enabling Protein Research for the Life Sciences Community

Ruedi Aebersold, Martin Kussmann

The biology and disease oriented branch of the Human Proteome Project (B/D-HPP) was established by the Human Proteome Organization (HUPO) with the main goal of supporting the broad application of state-of-the-art measurements of proteins and proteomes by l ...
