摘要

The so-called mixed feedback loop (MFL) with microRNA is a small two-gene network where microRNA regulates the translation of mRNA by base pairing with the mRNA. It has been developed to show that the MFL is a representative motif of genetic regulation networks. The present paper is mainly concerned with the issues of dynamics for the mixed feedback loop (MFL)integrated with microRNA. A simple mathematical model of the motif is proposed based on the biochemical interactions. It is shown that, by itself, this motif can serve both as a monostable and a bistable switch depending on a kinetic parameter range. The results emphasize the role of microRNA in the function of genetic modules and the regulation of itself.
