Engineering Modular 3D Liver Culture Microenvironments In Vitro to Parse the Interplay between Biophysical and Biochemical Microenvironment Cues on Hepatic Phenotypes

In vitro models of human liver functions are used across a diverse range of applications in preclinical drug development and disease modeling, with particular increasing interest in models that capture facets of liver inflammatory status. This study invest ...

Compound 18 Improves Glucose Tolerance in a Hepatocyte TGR5-dependent Manner in Mice

Kristina Schoonjans, Adriano Maida

The bile acid receptor, TGR5, is a key regulator of glucose homeostasis, but the mechanisms by which TGR5 signaling improves glucose regulation are incompletely defined. In particular, TGR5 has an increasingly appreciated role in liver physiology and patho ...

Pharmacological induction of a progenitor state for the efficient expansion of primary human hepatocytes

Didier Trono, Matthias Lütolf, Evaristo Jose Planet Letschert, Marc Samuel Friedli, Nathalie Brandenberg, Marco Cassano, Carmen Maria Unzu Ezquerro

The liver is an organ with strong regenerative capacity, yet primary hepatocytes have a low amplification potential in vitro, a major limitation for the cell-based therapy of liver disorders and for ex vivo biological screens. Induced pluripotent stem cell ...

Beneficial effects of Human Mesenchymal Stromal Cells on Porcine Hepatocyte Viability and Albumin Secretion

Sandrine Gerber, François Rémi Pierre Noverraz, Luca Szabó, Solène Marcelle Françoise Marie Passemard, Aurélien Thomas

Porcine hepatocytes transplanted during acute liver failure might support metabolic functions until the diseased liver recovers its function. Here, we isolated high numbers of viable pig hepatocytes and evaluated hepatocyte functionality after encapsulatio ...

Diurnal Oscillations in Liver Mass and Cell Size Accompany Ribosome Assembly Cycles

Frédéric Bruno Martin Gachon, Daniel Alain Dominique Marie Mauvoisin, Jingkui Wang

The liver plays a pivotal role in metabolism and xenobiotic detoxification, processes that must be particularly efficient when animals are active and feed. A major question is how the liver adapts to these diurnal changes in physiology. Here, we show that, ...

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 ...

Glutamate Cysteine Ligase-Modulatory Subunit Knockout Mouse Shows Normal Insulin Sensitivity but Reduced Liver Glycogen Storage

Pierre Magistretti, Kim Do

Glutathione (GSH) deficits have been observed in several mental or degenerative illness, and so has the metabolic syndrome. The impact of a decreased glucose metabolism on the GSH system is well-known, but the effect of decreased GSH levels on the energy m ...

Systems proteomics of liver mitochondria function

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

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 ...

AMP-activated protein kinase : strategies for activation and downstream target identification

Serge Thanh Son Ducommun

AMP-activated protein kinase (AMPK) is an evolutionally conserved key sensor of cellular energy status. Under conditions of cellular energy stress, AMPK is activated and will switch off anabolic processes that consume ATP, while activating catabolic proces ...

A method to identify and validate mitochondrial modulators using mammalian cells and the worm C-elegans

Johan Auwerx, Laurent Mouchiroud, Richardus Houtkooper, Pénélope Andreux, Xu Wang, Adrienne Joëlle Laurence Mottis, Norman Lionel Moullan, Virginija Jovaisaite, Sabrina Bichet

Mitochondria are semi-autonomous organelles regulated by a complex network of proteins that are vital for many cellular functions. Because mitochondrial modulators can impact many aspects of cellular homeostasis, their identification and validation has pro ...
