Nuclear Size and Shape Control

Seminars in Cell and Developmental Biology, 2022
The nucleus displays a wide range of sizes and shapes in different species and cell types, yet its size scaling and many of the key structural constituents that determine its shape are highly conserved. In this review, we discuss the cellular properties and processes that contribute to nuclear size and shape control, drawing examples from across ...

Re-sizing of nuclear pores

Nature Reviews Molecular Cell Biology, 2021
Zimmerli and Allegretti et al. show, in fission yeast, that nuclear pores constrict under energy deprivation or osmotic stress, which is linked to a reduction in nuclear membrane tension.

Nuclear size and compressibility

Soviet Physics Journal, 1982
Data on electron scattering on nuclei and spectra of mesoatoms and atoms are used to construct new expressions for nuclear size, which consider the effects of shells and deformations together with the dependence on A and Z. The compressibility of nuclei is also considered.

Nucleon size and the attractive nuclear force

Physical Review C, 1987
That the size of a nucleon increases when bound is shown to follow in first order from the attractive nature of the binding potential. We give two simple demonstrations of the connection of size change with the sign of the external potential, the generality of which helps to connect a wide class of successful explanations of medium modifications of the

Effects of Macromolecular Crowding on Nuclear Size

Experimental Cell Research, 1995
The concentration of macromolecules inside cells is high, and the resultant crowding of cytoplasm can be expected to affect many interactions involving macromolecular assemblies. Here, we have examined the effect of solute size and concentration on nuclear volume in saponin-permeabilized macrophages.

Nuclear genome size in Selaginella

Genome, 2007
Estimates of nuclear genome size for 9 Selaginella species were obtained using flow cytometry, and measurements for 7 of these species are reported for the first time. Estimates range from 0.086 to 0.112 pg per holoploid genome (84–110 Mb). The data presented here agree with the previously published flow cytometric results for S.

Relation of Nuclear Size to Saturation and Nuclear Compressibility

Reviews of Modern Physics, 1958
The solution of the nuclear many-body problem is described, and the approximation method on which the solution is based is described in physical terms. No attempt is made to describe the formal theory which must be invoked to justify the plausibility arguments which are given. The saturation of nuclear matter is discussed. (W.D.M.)

Control of Nuclear Size by NPC Proteins

2014
The architecture of the cell nucleus in cancer cells is often altered in a manner associated with the tumor type and aggressiveness. Therefore, it has been the central criterion in the pathological diagnosis and prognosis of cancer. However, the molecular mechanism behind these observed changes in nuclear morphology, including size, remains completely ...

Nuclear size and related topics

Nuclear Physics A, 2001
Abstract Experimental studies on nuclear sizes and related topics are reviewed. The recent development of radioactive nuclear beams has enabled us to study the nuclear sizes of unstable nuclei. The nuclear sizes for unstable nuclei, which are deduced by the interaction cross sections and reaction cross sections, are mainly reviewed.

Nuclear sizes and the Coulomb Displacement Energy

Acta Physica Hungarica A) Heavy Ion Physics, 1997
Data on Coulomb Displacement Energies in the mass range A = 40 - 240 are analyzed in the deformed Liquid Drop model and in the independent particle model. Reduced half-widths of Woods-Saxon mean-field potential of the resulting neutron-excess distributions are deduced.
