Title: Modeling post-transcriptional regulation and large deviations in stochastic gene expressionAbstract: In diverse cell populations, phenotypic variations are often observed even among genetically identical cells in a homogeneous environment. Recent research indicates that such `non-genetic individuality' can be driven by rare events arising from the intrinsic stochasticity of gene expression. These observations motivate the analysis of fluctuations and large deviations in stochastic…
