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 …

Orchestration of DNA damage checkpoint dynamics across the human cell cycle

HX Chao, CE Poovey, AA Privette, GD Grant, HY Chao… - Cell systems, 2017 - cell.com
Although molecular mechanisms that prompt cell-cycle arrest in response to DNA damage
have been elucidated, the systems-level properties of DNA damage checkpoints are not …

Size-dependent increase in RNA polymerase II initiation rates mediates gene expression scaling with cell size

XM Sun, A Bowman, M Priestman, F Bertaux… - Current Biology, 2020 - cell.com
Cell size varies during the cell cycle and in response to external stimuli. This requires the
tight coordination, or" scaling," of mRNA and protein quantities with the cell volume in order …

A mechanism for epithelial-mesenchymal heterogeneity in a population of cancer cells

S Tripathi, P Chakraborty, H Levine… - PLoS computational …, 2020 - journals.plos.org

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 …

Concentration fluctuations in growing and dividing cells: Insights into the emergence of concentration homeostasis

C Jia, A Singh, R Grima - PLoS computational biology, 2022 - journals.plos.org
Intracellular reaction rates depend on concentrations and hence their levels are often
regulated. However classical models of stochastic gene expression lack a cell size …
