In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Cancer cells with a cell nucleus that is easily deformed are more sensitive to drugs that damage DNA. These are the findings of a new study by researchers at Linköping University in Sweden. The ...

Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane. This new 'gateway into the ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

Bone implants often fail to fully integrate with surrounding tissue, limiting their effectiveness in regeneration. A natural but often overlooked cellular process could hold the key to better outcomes ...

An international study led by the University of Basel has discovered that nuclear pore complexes—tiny gateways in the nuclear membrane—are not rigid or gel-like as once thought. Their interiors are ...

(A) Experimental design. (B) Behavior assessments using open field tests. Heatmaps illustrate time spent (red) and movement trajectories (green). The PD group exhibited decreased movement speed ...

Missing the beginning of the film. The film explores the structure and function of plant and animal cells using a microscope. It begins with observing onion cells, highlighting their components such ...

The investigations of KIT researchers have shown that biomolecular condensates enable fast yet reliable activation of the right genes. “Biomolecular condensates are tiny drops that form in specific ...
