ABSTRACT: This is a complex model to examine mechanisms that govern MAPK pathway dynamics in Chinese hamster ovary (CHO) cell lines, particularly the role of adapter targeted negative feedback mechanism in generating complete signal adaptation.

A computational study of feedback effects on signal dynamics in a mitogen-activated protein kinase (MAPK) pathway model.

Biotechnology progress 20010301 2

Exploiting signaling pathways for the purpose of controlling cell function entails identifying and manipulating the information content of intracellular signals. As in the case of the ubiquitously expressed, eukaryotic mitogen-activated protein kinase (MAPK) signaling pathway, this information content partly resides in the signals' dynamical properties. Here, we utilize a mathematical model to examine mechanisms that govern MAPK pathway dynamics, particularly the role of putative negative feedba  ...[more]
