Stochastic gene expression (SGE) is involved in an evergrowing number of aspects of cellular life. It is typically an area of research needing modelization and interdisciplinary collaboration between biologists, bioinformaticians, physicists and mathematicians. SGE is an important aspect of cellular physiology that has to be integrated into systemic approaches and as such it is now the object of much attention of the international community. It raises a number of questions regarding its role in organisms, notably in developmental biology and could have profound consequences for biological theories: is it a "noise" that disrupts the operation of the genetic program, does it fits into a vision based on the theories of self-organization, or does it implies a conceptual framework change such as cellular Darwinism ?
This conference brought together experimental and theoretical biologists, modelers, epistemologists and philosophers who addressed all those issues. This conference attracted a large audience and was a successful interdisciplinary exchange.
The following topics will be addressed:
Philosophy:
- Overview of determinism and probabilism
- What is chance?
- Objective and subjective probability
- Determinism in biology (from an historical and philosophical perspective)
- The example of physics (probability and indeterminism in statistical and quantum physics)
- Sociological and epistemological obstacles to probabilism in Biology
Biology:
- Overview of stochastic gene expression
- What are the causes of stochastic expression (diffusion of molecules, chromatin effects, etc.)
- Does stochastic gene expression contradict the genetic programming theory?
- The role of stochastic gene expression in cell differentiation and embryo development
- The modelization of stochastic gene expression and stochastic cell differentiation
-The role of stochastic gene expression in cancer
The meeting will be followed by an “Atelier d’approfondissement des questions ouvertes” (in French), that will be organized on the 23rd of November.
