Quantitative single cell analysis uncovers the life/death decision in CD95 network

Jörn H. Buchbinder, Dennis Pischel, Kai Sundmacher, Robert J. Flassig, Inna N. Lavrik, Denis Thieffry
2018 PLoS Computational Biology  
The related life/death decision strictly depends on cell-to-cell variability in the formation of the death-inducing complex (DISC) on one side (extrinsic noise) vs. stochastic gene expression of the NF-κB  ...  Moreover, our analysis has uncovered that the stochasticity in apoptosis and NF-kB pathways leads not only to survival or death of a cell, but also causes a third type of response to CD95 stimulation that  ...  The crosstalk between apoptotic and anti-apoptotic pathways plays a key role in shaping life/death decisions in the cell.  ...

Systems biology of death receptor networks: live and let die

I N Lavrik
2014 Cell Death and Disease  
Death receptor activation leads to the formation of death receptor signaling platforms, resulting in the demolition of the cell.  ...  Creation of mathematical models of death receptor signaling led to an enormous progress in the quantitative understanding of the network regulation and provided fascinating insights into the mechanisms  ...  the Helmholtz-Russia Joint Research Groups-2008-2 and RFFI 14-04-00699 for supporting our work.  ...

Measuring and Modeling Apoptosis in Single Cells

Sabrina L. Spencer, Peter K. Sorger
2011 Cell  
Here we review progress made over the last decade in using mathematical models and quantitative, often single-cell, data to study apoptosis.  ...  Cell death plays an essential role in the development of tissues and organisms, the etiology of disease, and the responses of cells to therapeutic drugs.  ...  ACKNOWLEDGMENTS The authors thank J.

Heterogeneous responses to low level death receptor activation are explained by random molecular assembly of the Caspase-8 activation platform

2019 PLoS Computational Biology  
To explain cell decision making downstream of death receptor activation, we developed a semi-stochastic model of DISC/RIPoptosome formation.  ...  The model highlights how kinetic proofreading leads to heterogeneous cell responses and results in fractional cell killing at low levels of receptor stimulation.  ...  Buchbinder JH, Pischel D, Sundmacher K, Flassig RJ, Lavrik IN. Quantitative single cell analysis uncovers the life/death decision in CD95 network.  ...

At a Crossroads to Cancer: How p53-Induced Cell Fate Decisions Secure Genome Integrity

Dario Rizzotto, Lukas Englmaier, Andreas Villunger
2021 International Journal of Molecular Sciences  
We argue that a comparative analysis of different types of p53 responses, elicited by different triggers in a time-resolved manner in well-defined model systems, is critical to understand the cell-type-specific  ...  Here, we discuss how mitotic errors alert the p53 network and give an overview of multiple ways that p53 can trigger cell death.  ...  Life-Death Decisions by p53-Flicking the Switch What ultimately defines cell fate after p53 activation in diverse cell types?  ...
