Advanced Functional Materials, EarlyView.A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires
Advanced Functional Materials, EarlyView.In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

JAMA: The Journal of the American Medical Association, 1975 The cell nucleus is a characteristic feature of most eukaryotic cells. It is a double-membrane-bound organelle that contains the genetic information of the cell packaged in the form of chromatin.

Immunocytochemistry of the cell nucleus
Electron Microscopy Reviews, 1990This electron microscopic review addresses in situ immunocytochemistry of the mammalian cell nucleus with special reference to the use of autoantibodies, which are the major source of antinuclear antibodies. The localization of many key nuclear antigens is documented and immunocytochemical data are related to the major functional processes of ...

The role of the cell nucleus in mechanotransduction
Current Opinion in Cell Biology, 2020Mechanical forces are known to influence cellular processes with consequences at the cellular and physiological level. The cell nucleus is the largest and stiffest organelle, and it is connected to the cytoskeleton for proper cellular function.

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.

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)].

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 ...

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.

Influenza A virus and the cell nucleus
Vaccine, 2006It is over 20 years since the publication of experiments that showed that influenza A virus RNA synthesis takes place in the cell nucleus and that here, the virus subverts the cellular transcription machinery to express and replicate its own single-strand RNA genome. In the years since, our understanding of the organisation of the nucleus has increased
