Scientists detail how chromosomes reorganize after cell division

Researchers have discovered key mechanisms and structural details of a fundamental biological process—how a cell nucleus and its chromosomal material reorganizes itself after cell division. The new findings in chromosomal ...

A model to decipher the complexity of gene regulation

How, where and when genes are expressed determine individual phenotypes. If gene expression is controlled by many regulatory elements, what, ultimately, controls them? And how does genetic variation affect them? The SysGenetiX ...

Supercoiling pushes molecular handcuffs along chromatin fibres

Gene regulation relies on complex structural arrangements and processes at the molecular level. One of them, called 'chromatin loop extrusion', strikingly resembles the quick-lacing system of some trail running shoes: as ...

Scientists model gene regulation with chromatin accessibility

Researchers from the Academy of Mathematics and Systems Science (AMSS) of the Chinese Academy of Sciences have teamed up with Stanford University and Tsinghua University scientists to successfully model data on gene regulation ...

DNA methylation affects superiority of hybrid plants

Hybrid vigor refers to when a crossbreed plant or animal shows superior traits compared to its parents. A research group has discovered that a gene involved in maintaining DNA methylation is closely connected to hybrid vigor ...

Learning to program cellular memory

What if we could program living cells to do what we would like them to do in the body? Having such control—a major goal of synthetic biology—could allow for the development of cell-based therapies that might one day replace ...

The controlled cell

(Phys.org)—An interdisciplinary effort at the Friedrich Miescher Institute for Biomedical Research (FMI) addressed the question of how mRNA content, which is translated into proteins, is regulated in the cell. Supported ...

The machinery of chromatin regulation

Ten years after the human genome was first published, researchers have found new clues into the machinery that influences gene function. The team, led by Bradley Bernstein, an associate professor of pathology at Massachusetts ...
