Machine learning-derived gut microbiome signature predicts fatty liver disease in the presence of insulin resistance

A simple predictive biomarker for fatty liver disease is required for individuals with insulin resistance. Here, we developed a supervised machine learning-based classifier for fatty liver disease using fecal 16S rDNA sequencing data. Based on the Kangbuk ...

Advanced metabolite mapping at ultra-high field using 1H-MRS, 1H-MRSI and macromolecules: applications in a rat model of type C hepatic encephalopathy

Dunja Simicic

Magnetic Resonance Spectroscopy (MRS) is the only technique capable of measuring a large number of metabolites simultaneously in vivo. Ultra-high magnetic fields (UHF) combined with ultra-short echo time (TE) sequences allow the detection of high-quality 1 ...

[13C]bicarbonate labelled from hyperpolarized [1-13C]pyruvate is an in vivo marker of hepatic gluconeogenesis in fasted state

Arnaud Comment, Rolf Gruetter, Josefina Adriana Maria Bastiaansen, Emine Can, Hikari Ananda Infinity Yoshihara

Hyperpolarized [1-13C]pyruvate enables direct in vivo assessment of real-time liver enzymatic activities by 13C magnetic resonance. However, the technique usually requires the injection of a highly supraphysiological dose of pyruvate. We herein demonstrate ...

Dissecting the role of the mitochondrial carrier SLC25A47

Nadia Bresciani

Transporters of the SLC25 mitochondrial carrier superfamily bridge cytoplasmic and mitochondrial metabolism by channeling metabolites across mitochondrial membranes and are pivotal for metabolic homeostasis. Despite their physiological relevance as gatekee ...

Spatial proteogenomics reveals distinct and evolutionarily conserved hepatic macrophage niches

Bart Deplancke, Wouter Saelens

The liver is the largest solid organ in the body, yet it remains incompletely characterized. Here we present a spatial proteogenomic atlas of the healthy and obese human and murine liver combining single-cell CITEseq, single-nuclei sequencing, spatial tran ...

Overview of oxidative stress findings in hepatic encephalopathy: From cellular and ammonium-based animal models to human data

Cristina Ramona Cudalbu, Dunja Simicic

Oxidative stress is a natural phenomenon in the body. Under physiological conditions intracellular reactive oxygen species (ROS) are normal components of signal transduction cascades, and their levels are maintained by a complex antioxidants systems partic ...

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

Ece Yildiz

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 ...

Comprehensive analysis of the circadian nuclear and cytoplasmic transcriptome in mouse liver

Felix Naef, Cédric Gobet, Clémence Yumie Syloun Hurni, Benjamin Dieter Weger

In eukaryotes, RNA is synthesised in the nucleus, spliced, and exported to the cytoplasm where it is translated and finally degraded. Any of these steps could be subject to temporal regulation during the circadian cycle, resulting in daily fluctuations of ...

Inhibition of SRC-mediated integrin signaling in bone marrow niche enhances hematopoietic stem cell function

Jörg Hülsken

Interaction with microenvironmental factors is crucial for the regulation of hematopoietic stem cell (HSC) function. Stroma derived factor (SDF)-1 alpha supports HSCs in the quiescent state and is central to the homing of transplanted HSCs. Here, we show t ...

Raman microspectroscopy reveals unsaturation heterogeneity at the lipid droplet level and validates an in vitro model of bone marrow adipocyte subtypes

Olaia Maria Naveiras Torres-Quiroga, Vasco Ledebur de Antas de Campos, Josefine Catharina Pedersen Tratwal, Daniel Naveed Tavakol, Charles Christopher Bataclan

Bone marrow adipocytes (BMAds) constitute the most abundant stromal component of adult human bone marrow. Two subtypes of BMAds have been described, the more labile regulated adipocytes (rBMAds) and the more stable constitutive adipocytes (cBMAds), which d ...

Iron status influences non-alcoholic fatty liver disease in obesity through the gut microbiome

Xavier Fernandez-Real Girona

Background: The gut microbiome and iron status are known to play a role in the pathophysiology of nonalcoholic fatty liver disease (NAFLD), although their complex interaction remains unclear. Results: Here, we applied an integrative systems medicine approa ...

Space-time logic of liver gene expression at sub-lobular scale

Felix Naef, Clémence Yumie Syloun Hurni, Colas Noé Droin

The mammalian liver is a central hub for systemic metabolic homeostasis. Liver tissue is spatially structured, with hepatocytes operating in repeating lobules, and sub-lobule zones performing distinct functions. The liver is also subject to extensive tempo ...
