Hypoxic Incubation Conditions for Optimized Manufacture of Tenocyte-Based Active Pharmaceutical Ingredients of Homologous Standardized Transplant Products in Tendon Regenerative Medicine

Romain Hamelin, Florence Armand, Diego Chiappe

Human fetal progenitor tenocytes (hFPT) produced in defined cell bank systems have recently been characterized and qualified as potential therapeutic cell sources in tendon regenerative medicine. In view of further developing the manufacture processes of s ...

Quantitative Mass Spectrometry Reveals Plasticity of Metabolic Networks in Mycobacterium smegmatis

John McKinney, Marc Moniatte, Romain Hamelin, Florence Armand, Diego Chiappe, Tarun Chopra

Mycobacterium tuberculosis has a remarkable ability to persist within the human host as a clinically inapparent or chronically active infection. Fatty acids are thought to be an important carbon source used by the bacteria during long term infection. Catab ...

Analysis of the S. pombe Meiotic Proteome Reveals a Switch from Anabolic to Catabolic Processes and Extensive Post-transcriptional Regulation

Viesturs Simanis, Marc Moniatte, Romain Hamelin, Florence Armand, Andrea Krapp, Lucien Fabrice Krapp, Diego Chiappe

Meiotic progression in S. pombe is regulated by stage-specific gene expression and translation, changes in RNA stability, expression of anti-sense transcripts, and targeted proteolysis of regulatory proteins. We have used SILAC labeling to examine the rela ...

Tissue Transglutaminase-mediated Glutamine Deamidation of beta-Amyloid Peptide Increases Peptide Solubility, Whereas Enzymatic Cross-linking and Peptide Fragmentation May Serve as Molecular Triggers for Rapid Peptide Aggregation

Horst Arthur Vogel, Yury Tsybin, Marc Moniatte, Adrian Schmid, Diego Chiappe, Enrico Condemi

Tissue transglutaminase (TGase) has been implicated in a number of cellular processes and disease states, where the enzymatic actions of TGase may serve in both, cell survival and apoptosis. To date, the precise functional properties of TGase in cell survi ...

Lysine acetylation stoichiometry and proteomics analyses reveal pathways regulated by sirtuin 1 in human cells

Diego Chiappe

Lysine acetylation is a widespread posttranslational modification affecting many biological pathways. Recent studies indicate that acetylated lysine residues mainly exhibit low acetylation occupancy, but challenges in sample preparation and analysis make i ...

An interplay between the p38 MAPK pathway and AUBPs regulates c-fos mRNA stability during mitogenic stimulation

Diego Chiappe, Tamara Tanos

Mitogen-activated protein kinase (MAPK) pathways constitute key regulatory elements linking extracellular stimuli to nuclear gene expression. Immediate-early responsive genes (IEGs) of the activator protein 1 (AP-1) family, such as fos, achieve peak expres ...

Phosphorylation at S87 is enhanced in synucleinopathies, inhibits alpha-synuclein oligomerization, and influences synuclein-membrane interactions

Patrick Aebischer, Hilal Lashuel, Bernard Schneider, Marc Moniatte, Diego Chiappe, Adrian Schmid, Abid Oueslati

Increasing evidence suggests that phosphorylation may play an important role in the oligomerization, fibrillogenesis, Lewy body (LB) formation, and neurotoxicity of alpha-synuclein (alpha-syn) in Parkinson disease. Herein we demonstrate that alpha-syn is p ...

Protein Corona: Impact of Lymph Versus Blood in a Complex In Vitro Environment

Heinrich Hofmann, Duncan Thomas Lindsay Alexander, Marc Moniatte, Marijana Mionic Ebersold, Débora Bonvin, Ulrich Aschauer, Diego Chiappe

In biological environments, the surface of nanoparticles (NPs) are modified by protein corona (PC) that determines their biological behavior. Unfortunately, in vitro tests still give different PC than in vivo tests causing in vitro-in vivo discrepancy; hen ...

Beyond Unpredictability: The Importance of Reproducibility in Understanding the Protein Corona of Nanoparticles

Heinrich Hofmann, Diego Chiappe, Sandra Caroline Galmarini, Lionel André Maurizi, Nadia Rachel Von Moos

While it is well established that the surface of a nanoparticle plays a pivotal role for the protein corona, the vast number of proteins present in biological media render general conclusions about affinities between nanoparticle surfaces and proteins nont ...

Characterization of the surfaceome of the metal-reducing bacterium Desulfotomaculum reducens

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Romain Hamelin, Elena Cristina Dalla Vecchia, Diego Chiappe, Paul Pao-Yun Shao

Desulfotomaculum reducens strain MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing Fe(III). Metal reduction in Gram-positive bacteria is poorly understood. Here, we investigated Fe(III) reduction with lactate, a non-fermentable s ...

Methods of protein corona isolation for magnetic nanoparticles

Heinrich Hofmann, Marc Moniatte, Marijana Mionic Ebersold, Débora Bonvin, Diego Chiappe

Nanoparticles (NPs) in contact with a biological environment get covered by proteins and some are loosely bound and some are tightly bound. The latter form a hard protein corona (HPC) which is known to determine their biological behavior. Therefore, in ord ...

A quantitative telomeric chromatin isolation protocol identifies different telomeric states

Joachim Lingner, Marc Moniatte, Romain Hamelin, Florence Armand, Diego Chiappe, Eric Aeby, Larissa Grolimund

Telomere composition changes during tumourigenesis, aging and in telomere syndromes in a poorly defined manner. Here we develop a quantitative telomeric chromatin isolation protocol (QTIP) for human cells, in which chromatin is cross-linked, immunopurified ...

Electron Capture and Transfer Dissociation: Peptide Structure Analysis at Different Ion Internal Energy Levels

Yury Tsybin, Marc Moniatte, Aleksey Vorobyev, Diego Chiappe, Hisham Ben Hamidane

We decoupled electron-transfer dissociation (ETD) and collision-induced dissociation of charge-reduced species (CRCID) events to probe the lifetimes of intermediate radical species in ETD-based ion trap tandem mass spectrometry of peptides. Short-lived int ...

The early communication stages between serine proteases and enterovirus capsids in the race for viral disintegration

Tamar Kohn, Shannon Christa David, Shotaro Torii, Diego Chiappe, Marie-Hélène Chantal Corre

Serine proteases are important environmental contributors of enterovirus biocontrol. However, the structural features of molecular interaction accounting for the susceptibility of enteroviruses to proteases remains unexplained. Here, we describe the molecu ...
