Robust and Stochastic Dynamics in Signal Transduction and Developmental Patterning

Noise and stochastic effect exist in most biological systems due to many intrinsic and extrinsic factors. In this talk, I will discuss strategies and principles for noise attenuation and robustness to genetic or/and environmental perturbations in cell signaling, embryonic patterning, and regeneration driven by stem cells. In one case, I will introduce a critical quantity that dictates capability of attenuating temporal noises in feedback systems. In another case, I will show that noises in molecular signal transduction actually enable reduction of stochastic effects in spatial patterns during embryonic development. In addition, I will present several new experimental data in yeast cells and zebrafish embryo that support our modeling and computational predictions.
