Eukaryotic cell size control and its relation to biosynthesis and senescence

S Xie, M Swaffer, JM Skotheim - Annual review of cell and …, 2022 - annualreviews.org
The most fundamental feature of cellular form is size, which sets the scale of all cell
biological processes. Growth, form, and function are all necessarily linked in cell biology, but …

The nuclear-to-cytoplasmic ratio: coupling DNA content to cell size, cell cycle, and biosynthetic capacity

S Balachandra, S Sarkar… - Annual review of genetics, 2022 - annualreviews.org
Though cell size varies between different cells and across species, the nuclear-to-
cytoplasmic (N/C) ratio is largely maintained across species and within cell types. A cell …

Increasing cell size remodels the proteome and promotes senescence

MC Lanz, E Zatulovskiy, MP Swaffer, L Zhang, I Ilerten… - Molecular cell, 2022 - cell.com
Cell size is tightly controlled in healthy tissues, but it is unclear how deviations in cell size
affect cell physiology. To address this, we measured how the cell's proteome changes with …

m6A RNA modification regulates innate lymphoid cell responses in a lineage-specific manner

Y Zhang, W Zhang, J Zhao, T Ito, J Jin, AO Aparicio… - Nature …, 2023 - nature.com
Innate lymphoid cells (ILCs) can quickly switch from a quiescent state to an active state and
rapidly produce effector molecules that provide critical early immune protection. How the …

RNA polymerase II dynamics and mRNA stability feedback scale mRNA amounts with cell size

MP Swaffer, GK Marinov, H Zheng, LF Valenzuela… - Cell, 2023 - cell.com
A fundamental feature of cellular growth is that total protein and RNA amounts increase with
cell size to keep concentrations approximately constant. A key component of this is that …

Feedback from nuclear RNA on transcription promotes robust RNA concentration homeostasis in human cells

S Berry, M Müller, A Rai, L Pelkmans - Cell Systems, 2022 - cell.com
RNA concentration homeostasis involves coordinating RNA abundance and synthesis rates
with cell size. Here, we study this in human cells by combining genome-wide perturbations …

Mechanisms of cellular mRNA transcript homeostasis

S Berry, L Pelkmans - Trends in Cell Biology, 2022 - cell.com
For most genes, mRNA transcript abundance scales with cell size to ensure a constant
concentration. Scaling of mRNA synthesis rates with cell size plays an important role, with …

Modelling capture efficiency of single-cell RNA-sequencing data improves inference of transcriptome-wide burst kinetics

W Tang, ACS Jørgensen, S Marguerat, P Thomas… - …, 2023 - academic.oup.com
Motivation Gene expression is characterized by stochastic bursts of transcription that occur
at brief and random periods of promoter activity. The kinetics of gene expression burstiness …

Eukaryotic cell size regulation and its implications for cellular function and dysfunction

Y Chadha, A Khurana… - Physiological …, 2024 - journals.physiology.org
Depending on cell type, environmental inputs, and disease, the cells in the human body can
have widely different sizes. In recent years, it has become clear that cell size is a major …

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 …
