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

Extending the Monod model of microbal growth with memory
Frontiers 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?
Frontiers 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 ...

Cell Cycle, 2007 Cell size plays an indirect role in cell proliferation, as cells must double in size before dividing. Cell size is largely determined by the activity of RNA polymerase I that controls ribosomal RNA synthesis and ribosome biogenesis. The type 1 insulin-like growth factor receptor (IGF-IR) and its docking protein, insulin receptor substrate-1 (IRS-1 ...

Cell Size Control in Yeast [PDF]
Current Biology, 2012 Cell size is an important adaptive trait that influences nearly all aspects of cellular physiology. Despite extensive characterization of the cell-cycle regulatory network, the molecular mechanisms coupling cell growth to division, and thereby controlling cell size, have remained elusive.

The Regulation of Cell Size [PDF]
Cell, 2013 An adult animal consists of cells of vastly different size and activity, but the regulation of cell size remains poorly understood. Recent studies uncovering some of the signaling pathways important for size/growth control, together with the identification of diseases resulting from aberrations in these pathways, have renewed interest in this field ...

Plant Production Science, 2019 Endoreduplication is the phenomenon by which cells increase their ploidy. Endoreduplication is initiated by the transition from the mitotic cell cycle to the endocycle, in which DNA replication occurs without a subsequent chromosome separation and ...

Cellularity of porcine adipose tissue: effects of growth and adiposity
Journal of Lipid Research, 1977 Adipose tissue, from two depots in pigs of three breeding groups with different propensities to fatten, was characterized in terms of weight of the adipose tissue organ, adipose cell number, and mean cell volume as determined by electronic counting of ...

Cell size, body size and Peto’s paradox
BMC Ecology and Evolution, 2022 AbstractCarcinogenesis is one of the leading health concerns afflicting presumably every single animal species, including humans. Currently, cancer research expands considerably beyond medicine, becoming a focus in other branches of natural science.

The TOR Signaling Pathway in Spatial and Temporal Control of Cell Size and Growth
Frontiers in Cell and Developmental Biology, 2017 Cell size is amenable by genetic and environmental factors. The highly conserved nutrient-responsive Target of Rapamycin (TOR) signaling pathway regulates cellular metabolic status and growth in response to numerous inputs.
