Hyperthermia and the Cell Nucleus
Radiation Research, 1982Recent reviews document that hyperthermic shock inhibits the major nuclear activities, including semiconservative DNA replication (1, 2). These inhibitions may result either from a direct effect of heat on the cell nucleus or as a consequence of changes in other cell compartments [e.g., cell membrane damage (3)].

ABSTRACT The ultimate book on the nucleus would require about a million pages just to present the complete base sequence of DNA in a single human nucleus, alphabetically. The three volumes of The Cell Nucleus, of course, make no pretense of offering that kind of information, but they provide a wide range of up-to-date information on the structure and ...

Purified DNA can be assembled into structures that closely resemble cell nuclei. The cell-free systems that allow this can be exploited to study assembly pathways for several components of the nucleus. They also offer great opportunities for the experimental analysis of nuclear function.

Cell nucleus as endogenous biological micropump
Biosensors and Bioelectronics, 2021Micropumps can generate directional microflows in blood vessels or bio-capillaries for targeted transport of nanoparticles and cells in vivo, which is highly significant for biomedical applications from active drug delivery to precision clinical therapy.

Nucleus is a specialized organelle that serves as a control tower of all the cell behavior. While traditional biochemical features of nuclear signaling have been unveiled, many of the physical aspects of nuclear system are still under question. Innovative biophysical studies have recently identified mechano-regulation pathways that turn out to be ...

Nucleus and nucleus-cytoskeleton connections in 3D cell migration
Experimental Cell Research, 2016Cell migration plays an important role in many physiological and pathological settings, ranging from embryonic development to cancer metastasis. Currently, accumulating data suggest that cells migrating in three-dimensional (3D) environments show well-defined differences compared to their well-established two-dimensional (2D) counterparts.

Editorial overview: Cell nucleus: The nucleus: a dynamic organelle
Current Opinion in Cell Biology, 2014The nucleus is perhaps the defining feature of ‘eukaryotes’ (Greek ‘eu-’ (with) ‘-karyon’ (kernel, nucleus)), and the emperor of all eukaryotic organelles in terms of scale and complexity of organization. It is, of course, the repository for almost all genomic information, encoded in DNA sequences wrapped into chromatin as discrete polymer packages ...

Guanine Quadruplexes in Cell Nucleus Metabolism
Molecular Biology, 2021Cell metabolism depends, to a large extent, on correct regulation of gene expression. One of the mechanisms of regulation is the formation of nucleic acid secondary structures, among which guanine quadruplexes (G-quadruplexes, or G4) are of particular importance.

AbstractThe origin of mitosis and the nuclear envelope were the pivotal processes in the evolutionary origin of the nucleus; they probably occurred in a wall‐less mutant bacterium that evolved a cytoskeleton and phagocytosis about 1500 million years ago.

To investigate the feasibility of inducing adipose-derived stem cells (ADSCs) to nucleus pulposus cells (NPCs).ADSCs were isolated from rabbit while NPCs were isolated from an allogeneic rabbit. NPCs were co-cultured with the 3rd generation ADSCs in co-cultured system. Only NPCs were cultured in single culturing group.
