Liver Systems Medicine : striving to develop non-invasive methods for diagnosing and treating NAFLD by combining mathematical modeling and biological research. LiSyM, is a multidisciplinary research network, in which molecular and cell biologists, clinical researchers, pharmacologists and experts in mathematical modeling examine the liver in its entirety. LiSyM research focuses on the metabolic liver disease non-alcoholic fatty liver disease (NAFLD), which includes non-alcoholic steatohepatitis (NASH). (NASH), the inflammatory form of NAFLD can follow NAFLD if it goes undetected. LiSyM scientists also investigate liver disease caused by exposure to selected harmful chemicals, drugs and other toxins. In LiSyM, 37 research groups at 23 scientific centers and institutions located around Germany have joined forces to tackle some of the most complex problems of the human body.

Disorders of the liver show up through changes in blood tests. These blood tests indicate markers for events taking place in the liver. Usually studies of liver tissue cannot be performed: as liver samples would need to be obtained through a liver biopsy, and this procedure is not without risk, therefore these samples are usually unavailable. Complex metabolism models based on existing and new scientific data can simulate changes in the liver caused by disease. They often reveal unknown relationships ...

Dr. Nachiket Vartak (TU University, Dortmund) investigates the role of a particular protein - the GTPase Rab18 - in initiating NAFLD. He tries to influence Rab18 pharmacologically so that NAFLD is not initiated. Vartak also analyzes how bile acids leave the liver. He hopes to find ways to improve the flow of bile in a liver with dysfunctional bile flow.

One of the tasks of the healthy liver is to store fat. Yet, at some stage, too much fat makes the liver sick. One critical time point occurs when a healthy fatty liver becomes inflamed and progresses to steatohepatitis, or NASH. LiSyM-Pillar I will identify what events lead to this transition. Does it occur in all parts of the liver? Which molecules indicate that it is taking place? Can the degeneration be stopped or undone - and if so, how?

Dr. Madlen Matz-Soja (University of Leipzig) investigates the importance of a control mechanism - the hedgehog signaling pathway - for fatty liver disease. She has shown that the signaling pathway directs how liver cells in NAFLD accumulate fat. Hedgehog also affects sex hormones in the liver. Therefore, Matz-Soya hopes to clarify why women and men suffer from cirrhosis and liver cancer with varying degrees of frequency.

Upon stimulation of cells with transforming growth factorb(TGF-b),Smad proteins form trimeric complexes and activate a broad spectrum of target genes. It remains unresolved which of the possible Smad complexes are formed in cellular contexts and how these contribute to gene expression. Combining quantitative mass spectrometry with a computational selection strategy, we investigate Smad complexes in the mouse hepatoma cell line Hepa1-6.

To investigate the underlying molecular principles of metabolic and morphogenic zonation of the human liver lobule, we generated an integrated epigenetic map across three zones (pericentral, intermediate and periportal) by methylation and transcriptomic analysis of hepatocytes captured by laser micro-dissection. We observe a deep link between epigenetic zonation of human liver and a zonated expression of metabolic and morphogenic pathways: Key transcriptionally zonated enzymes in xenobiotic and ...

Liver macrophages (LMs) play a central role in acute and chronic liver pathologies. In our study, we sought to gain further insight into the role of LMs in different liver pathologies and into their characteristics after isolation from liver tissue. Here we will characterize LMs in human liver tissue sections using immunohistochemistry and bioinformatic image analysis. We investigate liver tissues characterized by antiinflammatory LMs which show a homogeneous distribution and increased cell numbers ...

We face a crisis in reproducibility, where it is impossible to believe most of the computational results shown in conferences and papers. Recent replication efforts and theoretical considerations indicate that most published research findings in biomedical research are wrong. This is especially problematic for the translation of computational models into the clinics. Modelling standards, software, and community initiatives are fundamental for reproducibility in systems biology and systems medicine. ...

ODE model describes dynamics of IFNalpha-induced signaling in Huh7.5 cells for a time scale up to 32 hours after stimulation with IFNalpha. The model consists of an IFN receptor model, formation/degradation and cytoplasmic/nuclear shuttling of STAT1-homodimers, STAT1-STAT2-heterodimers and STAT1-STAT2-IRF9 (ISGF3) complexes. On top, formation of feedback proteins STAT1, STAT2, IRF9, USP18, SOCS1, SOCS3 and IRF2 and corresponding influences on IFNalpha signaling dynamics was incorporated. The model ...
