Modeling cell size regulation: From single-cell-level statistics to molecular mechanisms and population-level effects

PY Ho, J Lin, A Amir - Annual review of biophysics, 2018 - annualreviews.org
Most microorganisms regulate their cell size. In this article, we review some of the
mathematical formulations of the problem of cell size regulation. We focus on coarse …

Mechanistic origin of cell-size control and homeostasis in bacteria

F Si, G Le Treut, JT Sauls, S Vadia, PA Levin, S Jun - Current Biology, 2019 - cell.com
Evolutionarily divergent bacteria share a common phenomenological strategy for cell-size
homeostasis under steady-state conditions. In the presence of inherent physiological …

Homeostasis of protein and mRNA concentrations in growing cells

J Lin, A Amir - Nature communications, 2018 - nature.com
Many experiments show that the numbers of mRNA and protein are proportional to the cell
volume in growing cells. However, models of stochastic gene expression often assume …

General quantitative relations linking cell growth and the cell cycle in Escherichia coli

H Zheng, Y Bai, M Jiang, TA Tokuyasu, X Huang… - Nature …, 2020 - nature.com

global mechanisms that coordinate cell growth,–. The foundation of bacterial cell cycle …

Intercellular variability in protein levels from stochastic expression and noisy cell cycle processes

M Soltani, CA Vargas-Garcia, D Antunes… - PLoS computational …, 2016 - journals.plos.org
Inside individual cells, expression of genes is inherently stochastic and manifests as cell-to-
cell variability or noise in protein copy numbers. Since proteins half-lives can be comparable …

Evidence that the human cell cycle is a series of uncoupled, memoryless phases

HX Chao, RI Fakhreddin, HK Shimerov… - Molecular systems …, 2019 - embopress.org
The cell cycle is canonically described as a series of four consecutive phases: G1, S, G2,
and M. In single cells, the duration of each phase varies, but the quantitative laws that …

Surface-to-volume scaling and aspect ratio preservation in rod-shaped bacteria

N Ojkic, D Serbanescu, S Banerjee - Elife, 2019 - elifesciences.org
Rod-shaped bacterial cells can readily adapt their lengths and widths in response to
environmental changes. While many recent studies have focused on the mechanisms …
