Cells maintain a characteristic size to function. Abnormal cell size is characteristic of cancer cells, but it’s unclear how healthy or diseased cells control their size. We use fission yeast to study cell size control because of their easy-to-measure rod shape. Fission yeast control their size in part though size-dependent nuclear accumulation of mitotic activator Cdc25. In this study, we investigate the pathways that influence the nuclear accumulation of Cdc25 in response to changes in cell size using quantitative live-cell fluorescence microscopy. Our work has the potential to reveal conserved regulatory networks involved in cell size control.
