Anuran Vocal Communication: Effects of Genome Size, Cell Number and Cell Size

Brain, Behavior and Evolution, 2021
Significant variation in genome size occurs among anuran amphibians and can affect cell size and number. In the gray treefrog complex in North America, increases in cell size in autotriploids of the diploid (<i>Hyla chrysoscelis</i>) altered the temporal structure of mate-attracting vocalizations and auditory selectivity for these ...

Extracellular control of cell size

Nature Cell Biology, 2001
Both cell growth (cell mass increase) and progression through the cell division cycle are required for sustained cell proliferation. Proliferating cells in culture tend to double in mass before each division, but it is not known how growth and division rates are co-ordinated to ensure that cell size is maintained.

Genetic control of cell size

Current Opinion in Genetics & Development, 2000
Over the past 25 years, the genetic control of cell size has mainly been addressed in yeast, a single-celled organism. Recent insights from Drosophila have shed light on the signalling pathways responsible for adjusting and maintaining cell size in metazoans.

Cell size relations for sonolysis

Ultrasound in Medicine & Biology, 2004
The occurrence of cell lysis following exposure to ultrasound (US) has been well documented; the specifics of the mechanistic process(es) involved have proven to be difficult to characterize. There appear to be two major mechanisms of US-induced cell lysis in vitro, acoustic cavitation and bubble transport. Both involve shear forces.

Cell size in Dictyostelium

Developmental Genetics, 1988
AbstractCellular slime mold amoebae have become a model system for the study of cell motility and the cytoskeleton. A basic problem which all cells face that involves the cytoskeleton is how to control their size. The varied ways in which cellular slime mold amoebae change their cell size‐by changing the size at which division occurs, by cell fusion ...

Electrofusion of cell-size liposomes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1994
Cell size liposomes of egg phosphatidylcholine (PC), trans-acylated egg phosphatidylethanolamine (PE), bovine brain phosphatidylserine (PS) and egg phosphatidylglycerol, suspended in 2.5% of polyethylene glycol (M(r) 8000), Ficoll (M(r) 400,000) or Dextran (M(r) 71,200) were aligned by dielectrophoresis and fused by applying a 1.7 kV/cm pulse of ...

Cell size versus body size in geophilomorph centipedes

The Science of Nature, 2015
Variation in animal body size is the result of a complex interplay between variation in cell number and cell size, but the latter has seldom been considered in wide-ranging comparative studies, although distinct patterns of variation have been described in the evolution of different lineages.

The phenomenology of cell size control

Current Opinion in Cell Biology, 2017
Cells control their size through an intricate balance of cell growth, cell division, and cell death. Extensive work on unicellular model organisms revealed that cell-size-dependent cell cycle progression accounts for major aspects of cell size regulation and provided insights into the underlying molecular mechanisms.
