The Novak–Tyson Model is a non-linear dynamics framework developed in the context of cell-cycle control by Bela Novak and John J. Tyson. It is a prevalent theoretical model that describes a hysteretic , bistable bifurcation of which many biological systems have been shown to express.
In this article, three predictions of the Novak-Tyson model were tested in an effort to conclude that hysteresis is the driving force for "cell-cycle transitions into and out of mitosis". The predictions of the Novak-Tyson model are generic to all saddle-node bifurcations.
Hysteresis is defined as the dependence of the state of a system on its history. The Novak–Tyson model is a mathematical model of cell cycle progression that predicts that irreversible transitions entering and exiting mitosis are driven by hysteresis.
Tyson has worked closely with high-profile individuals within the field of cell biology. Cell Cycle Control by a Minimal Cdk Network was written by Tyson in tandem with Claude Gerard, Damien Coudreuse, and Béla Novák. The paper has been highly cited and takes a critical look at the possible origin of the eukaryotic cell and how the minimal ...
The Novak-Tyson model is a mathematical model used to explain such regulatory loop that predicted the irreversible transition into mitosis driven by hysteresis. [5] Through experiments in Xenopus laevis cell-free egg extracts, such model was confirmed as the basis for entry into mitosis. Once cyclin concentration reaches a certain minimum ...
