Short-term memory in gene induction reveals the regulatory principle behind stochastic IL-4 expression.

Method	Abstract: "Here, [researchers] study the interleukin-4 gene (il4) in T-helper lymphocytes, combining mathematical modeling with the experimental quantification of expression variability and critical parameters."
Comments	P.5 right column bottom paragraph: "The chromatin memory time of the chromatin state found for IL-4 expression, 2.9 days, is one order of magnitude larger than the characteristic time of intracellular IL-4 turnover (~2h Supplementary Mathematical Appendix 1) that provides a basal ‘memory’ for gene expression (Sigal et al, 2006)."
