Multistable switches and their role in cellular differentiation networks
Biological multistable switches stabilize cell types during development. Adding two identical switches to gene regulatory networks significantly enhances cell type separation and directional transitions, shaping lineage trees.
Area of Science:
- Systems Biology
- Developmental Biology
- Computational Biology
Background:
- Gene regulatory networks (GRNs) control cellular differentiation.
- Gene expression noise can impact this process.
- Multistable switches in GRNs may stabilize cell types and structure lineage trees.
Purpose of the Study:
- Investigate the role of multistable switches in GRNs.
- Assess their impact on cell type stability and lineage tree structure.
Main Methods:
- Developed a new methodology to study GRNs with embedded multistable switches.
- Applied the method to a hematopoietic GRN and random Boolean networks (RBNs).
- Analyzed network attractors representing cell types, focusing on attractor separation and directionality.
Main Results:
- Adding one multistable switch modestly increased attractor pair separation.
- Adding two identical switches significantly enhanced attractor separation.
- Two identical switches also increased directional transitions between cell types, an effect not seen with one switch.
Conclusions:
- Multistable switches contribute to lineage tree structure.
- These switches stabilize cell types during differentiation.
