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

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

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 ...

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

Felix Naef, Colas Noé Droin, Clémence Yumie Syloun Hurni

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 ...

Probiotics improve the neurometabolic profile of rats with chronic cholestatic liver disease

Cristina Ramona Cudalbu Moldovan, Veronika Rackayová, Jocelin Grosse, Emmanuelle Ines Flatt

Chronic liver disease leads to neuropsychiatric complications called hepatic encephalopathy (HE). Current treatments have some limitations in their efficacy and tolerability, emphasizing the need for alternative therapies. Modulation of gut bacterial flora ...

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 ...

Emerging functions of the nuclear receptor LRH-1 in liver physiology and pathology

Kristina Schoonjans, Hadrien Charles Edouard Demagny, Yu Sun

Nuclear receptors play pleiotropic roles in cell differentiation, development, proliferation, and metabolic processes to govern liver physiology and pathology. The nuclear receptor, liver receptor homolog-1 (LRH-1, NR5A2), originally identified in the live ...

Circadian dynamics of RNA localisation in the mammalian liver

Clémence Yumie Syloun Hurni

Gene expression in eukaryotes is a complex multi-step process. It starts in the nucleus with transcription, the synthesis of a mRNA copy from a DNA template. While in the nucleus, the RNA transcript is subject to multiple co- and post-transcriptional modif ...

Pancreatic Sirtuin 3 Deficiency Promotes Hepatic Steatosis by Enhancing 5-Hydroxytryptamine Synthesis in Mice With Diet-Induced Obesity

Johan Auwerx, Kristina Schoonjans

Sirtuin 3 (SIRT3) is a protein deacetylase regulating beta-cell function through inhibiting oxidative stress in obese and diabetic mice, but the detailed mechanism and potential effect of beta-cell-specific SIRT3 on metabolic homeostasis, and its potential ...

Defined matrices for epithelial organoid culture and disease modelling

Saba Rezakhani

Advances in our understanding of the biology of stem cells and their niches have provided the necessary foundation to create in vitro complex self-organizing three-dimensional (3D) structures called organoids. While organoids represent a highly promising n ...

Assessment of Aspartate and Bicarbonate Produced From Hyperpolarized [1-13C]Pyruvate as Markers of Renal Gluconeogenesis

Arnaud Comment, Hikari Ananda Infinity Yoshihara

As both a consumer and producer of glucose, the kidney plays a significant role in glucose homeostasis. Measuring renal gluconeogenesis requires invasive techniques, and less invasive methods would allow renal gluconeogenesis to be measured more routinely. ...

Longitudinal osmotic and neurometabolic changes in young rats with chronic cholestatic liver disease

Cristina Ramona Cudalbu Moldovan, Veronika Rackayová

Type C hepatic encephalopathy (type C HE) is increasingly suspected in children with chronic liver disease (CLD), and believed to underlie long-term neurocognitive difficulties. The molecular underpinnings of type C HE in both adults and children are incom ...

Transcriptomic analysis across liver diseases reveals disease-modulating activation of constitutive androstane receptor in cholestasis

Kristina Schoonjans

Background & Aims: Liver diseases are caused by many factors, such as genetics, nutrition, and viruses. Therefore, it is important to delineate transcriptomic changes that occur in various liver diseases. Methods: We performed high-throughput sequencing of ...
