Controlling Nuclear NF-?B Dynamics by ?-TrCP-Insights from a Computational Model.


ABSTRACT: The canonical nuclear factor kappa-light-chain-enhancer of activated B cells (NF-?B) signaling pathway regulates central processes in mammalian cells and plays a fundamental role in the regulation of inflammation and immunity. Aberrant regulation of the activation of the transcription factor NF-?B is associated with severe diseases such as inflammatory bowel disease and arthritis. In the canonical pathway, the inhibitor I?B suppresses NF-?B's transcriptional activity. NF-?B becomes active upon the degradation of I?B, a process that is, in turn, regulated by the ?-transducin repeat-containing protein (?-TrCP). ?-TrCP has therefore been proposed as a promising pharmacological target in the development of novel therapeutic approaches to control NF-?B's activity in diseases. This study explores the extent to which ?-TrCP affects the dynamics of nuclear NF-?B using a computational model of canonical NF-?B signaling. The analysis predicts that ?-TrCP influences the steady-state concentration of nuclear NF-?B, as well as changes characteristic dynamic properties of nuclear NF-?B, such as fold-change and the duration of its response to pathway stimulation. The results suggest that the modulation of ?-TrCP has a high potential to regulate the transcriptional activity of NF-?B.
