abstract = {NF-κB is a protein complex that occurs in almost all
animal cell types. It regulates the cellular immune
responses to stimuli in the nucleus. Dysregulation of NF-κB
can cause severe diseases like chronic inflammation,
autoimmune diseases or cancer. We modeled the two major
pathways leading from the external cellular stimulation of
the CD40 receptor to the nuclear translocation of NF-κB
dimers, the canonical and non-canonical pathway. Based on
literature data, we developed two Petri net models
describing these pathways. In a third Petri net, we combined
the two models, introducing crosstalk specific in
CD40L-stimulated B cells. In terms of structural properties,
we checked the Petri nets for their consistency and
correctness. To explore differences and similarities, we
compared structural properties and the simulation behavior
of the models. The non-canonical NF-κB pathway exhibited a
more diverse regulation than the canonical pathway. Applying
in silico knockout analyses, we were able to quantify the
relevance of individual biochemical processes. We predicted
interrelationships, e.g., between the synthesis of the
protein NF-κB-inducing kinase and the processing of the
precursor protein p100. The activation of the transcription
factors, p50-RelA and p52-RelB, was affected by most of the
knockouts. The results of the in silico knockout were in
accordance with experimental studies. The Petri net models
provide a basis for further analyses and could be extended
to include gene expression, additional pathways, molecular
processes, and kinetic data.},
