Talk at the Jamboree 2021 about epigenomic map of human liver zonation and loss of zonation in end-stage liver disease

Jamboree presentation

Computational modeling and simulation become increasingly important for Systems Medicine. A number of corresponding software tools have been developed but require scientists to encode their models in an imperative programming language. Morpheus [1,2], on the other hand, is an extensible open-source software framework that is entirely based on declarative modeling. It uses the domain-specific language MorpheusML to define multicellular models through a user-friendly GUI and has since proven ...

We face a reproducibility crisis and computational science, with most published models neither being accessible nor reproducible. The Systems Biology Markup Language (SBML) is the de facto standard format for encoding pathway based models, which provides a means for exchanging process based models between researchers and tools. The talk gives an overview of SBML and SBML-based tools.

Assessment of liver function is a key task in hepatology but accurate quantification of hepatic function has remained a clinical challenge. Dynamic liver function tests are a promising tool for the non-invasive evaluation of liver function in vivo. Quantitative dynamical liver function tests evaluate the function of the liver via the clearance of a given test substance, thereby providing in vivo information on the metabolic capacity of the liver. Here, we present recent results in establishing ...

The spatial separation of metabolic functions along the porto-central axis within the liver lobule is termed liver zonation. The zonated metabolic endowment of hepatocytes along the sinusoid are partially influenced by adaption to changing contents of nutrients and oxygen, but is mainly regulated by the morphogenic Wnt/β-Catenin signaling pathway. How morphogens contribute to the lobular distribution of metabolic pathways is part of an evolving field in science since the last decade. For long, ...

I gave this talk at the SBMC 2018 in Bremen (Session: Systems Medicine & Clinical applications)

Computational models complement experimental methods in the analysis of tissue organization processes, and play an increasingly important role in systems biology and systems medicine. Creating and parameterizing mathematical models for the simulation of biological tissue dynamics at multiple scales is still a complex and resource-consuming task, which necessitates skills in diverse scientific disciplines. The software TiSim was conceived to facilitate programming, integration and deployment of ...

In the growing elderly societies, the incidence of primary and secondary liver tumors is continuously increasing. Surgical interventions like partial liver resections are often the only curative therapy removing more than 70% of the total liver mass. In humans, 20% to 30% of the remaining liver is required for liver regeneration. Successful restoration of the liver mass ultimately depends on the regenerative and metabolic capacity of the hepatocytes in the remnant liver. This, however, might be ...

The transforming growth factor (TGF)-β has been identified as a master regulator of liver fibrogenesis. Thus, targeting TGF-β1 pathway might modulate chronic liver disease (CLD) development and/or progression in murine model. Galunisertib (Ly2157299), already in clinical studies phase II, is an oral small molecule targeting TGF-β type I receptor (ALK-5).
