Artificial Modulation and Rewiring of Cell Cycle Progression Using Synthetic Circuits in Fission Yeast.

Abstract

Cell cycle control is a central aspect of the biology of proliferating eukaryotic cells. However, progression through the cell cycle relies on a highly complex network, making it difficult to unravel the core design principles underlying the mechanisms that sustain cell proliferation and the ways in which they interact with other cellular pathways. In this context, the use of a synthetic approach to simplify the cell cycle network in unicellular genetic models such as fission yeast has opened the door to studying the biology of proliferating cells from unique perspectives. Here, we provide a series of methods based on a minimal cell cycle module in the fission yeast Schizosaccharomyces pombe that allows for an unprecedented artificial control of cell cycle events, enabling the rewiring and remodeling of cell cycle progression.
