Small RNAs Establish Delays and Temporal Thresholds in Gene Expression (2008)

Legewie, Stefan, Dienst, Dennis, Wilde, Annegret, Herzel, Hanspeter, Axmann, Ilka M.

Non-coding RNAs are crucial regulators of gene expression in prokaryotes and eukaryotes, but it remains poorly understood how they affect the dynamics of transcriptional networks. We analyzed the...

Mathematical Modeling Identifies Inhibitors of Apoptosis as Mediators of Positive Feedback and Bistability (2006)

Stefan Legewie, Nils Blüthgen, Hanspeter Herzel

The intrinsic, or mitochondrial, pathway of caspase activation is essential for apoptosis induction by various stimuli including cytotoxic stress. It depends on the cellular context, whether...

Recurrent design patterns in the feedback regulation of the mammalian signalling network

Legewie, Stefan, Herzel, Hanspeter, Westerhoff, Hans V, Blüthgen, Nils

Biochemical networks are characterized by recurrent patterns and motifs, but the design principles underlying the dynamics of the mammalian intracellular signalling network remain unclear. We...

Competing Docking Interactions can Bring About Bistability in the MAPK Cascade

Legewie, Stefan, Schoeberl, Birgit, Blüthgen, Nils, Herzel, Hanspeter

Mitogen-activated protein kinases are crucial regulators of various cell fate decisions including proliferation, differentiation, and apoptosis. Depending on the cellular context, the Raf-Mek-Erk...

Systems-level interactions between insulin–EGF networks amplify mitogenic signaling

Borisov, Nikolay, Aksamitiene, Edita, Kiyatkin, Anatoly, Legewie, Stefan, Berkhout, Jan, Maiwald, Thomas, ...

Crosstalk mechanisms have not been studied as thoroughly as individual signaling pathways. We exploit experimental and computational approaches to reveal how a concordant interplay between the...
