Temperature Responses of Heterotrophic Bacteria in Co-culture With a Red Sea Synechococcus Strain

open access: yesFrontiers in Microbiology, 2021
Interactions between autotrophic and heterotrophic bacteria are fundamental for marine biogeochemical cycling. How global warming will affect the dynamics of these essential microbial players is not fully understood.

Cell-size control

open access: yesCurrent Biology, 2021
A fundamental and still mysterious question in cell biology is "How do cells know how big they are?". The fact that they do is evident from the strict maintenance of size homeostasis within populations of cells and has been verified by a variety of creative experiments over the past 100 years.

Identification of transcriptional and metabolic programs related to mammalian cell size [PDF]

open access: yes, 2014
Background Regulation of cell size requires coordination of growth and proliferation. Conditional loss of cyclin-dependent kinase 1 in mice permits hepatocyte growth without cell division, allowing us to study cell size in vivo using transcriptomics and ...

How Metabolic Rate Relates to Cell Size

open access: yes, 2022
SIMPLE SUMMARY: The metabolic conversion of resources into living structures and processes is fundamental to all living systems. The rate of metabolism (‘fire of life’) is critical for supporting the rates of various biological processes (‘pace of life’),

Cell Cycle Arrest by Supraoptimal Temperature in the Alga Chlamydomonas reinhardtii

open access: yesCells, 2019
Temperature is one of the key factors affecting growth and division of algal cells. High temperature inhibits the cell cycle in Chlamydomonas reinhardtii.

Expansion of the Inguinal Adipose Tissue Depot Correlates With Systemic Insulin Resistance in C57BL/6J Mice

open access: yesFrontiers in Cell and Developmental Biology, 2022
To accommodate surplus energy, the adipose tissue expands by increasing adipocyte size (hypertrophy) and number (hyperplasia). The presence of hypertrophic adipocytes is a key characteristic of adipose tissue dysfunction. High-fat diet (HFD) fed C57BL/6J

Revisiting the hypothesis of an energetic barrier to genome complexity between eukaryotes and prokaryotes [PDF]

open access: yesRoyal Society Open Science, 2020
The absence of genome complexity in prokaryotes, being the evolutionary precursors to eukaryotic cells comprising all complex life (the prokaryote–eukaryote divide), is a long-standing question in evolutionary biology.

Cell cycle length, cell size, and proliferation rate in hydra stem cells [PDF]

open access: yes, 1990
We have analyzed the cell cycle parameters of interstitial cells in Hydra oligactis. Three subpopulations of cells with short, medium, and long cell cycles were identified. Short-cycle cells are stem cells; medium-cycle cells are precursors to nematocyte

Extending the Monod model of microbal growth with memory

open access: yesFrontiers in Marine Science, 2022
Monod’s model describes the growth of microorganisms using a hyperbolic function of extracellular resource concentration. Under fluctuating or limited resource concentrations this model performs poorly against experimental data, motivating the more ...

What programs the size of animal cells?

open access: yesFrontiers in Cell and Developmental Biology, 2022
The human body is programmed with definite quantities, magnitudes, and proportions. At the microscopic level, such definite sizes manifest in individual cells - different cell types are characterized by distinct cell sizes whereas cells of the same type ...
