Physical force alone spurs gene expression, study reveals

Cells will ramp up gene expression in response to physical forces alone, a new study finds. Gene activation, the first step of protein production, starts less than one millisecond after a cell is stretched—hundreds of times ...

An 'oracle' for predicting the evolution of gene regulation

Despite the sheer number of genes that each human cell contains, these so-called "coding" DNA sequences comprise just 1% of our entire genome. The remaining 99% is made up of "non-coding" DNA—which, unlike coding DNA, does ...

New imaging method reveals nanoscale details about DNA

Researchers have developed a new enhanced DNA imaging technique that can probe the structure of individual DNA strands at the nanoscale. Since DNA is at the root of many disease processes, the technique could help scientists ...

Force triggers gene expression by stretching chromatin

How genes in our DNA are expressed into traits within a cell is a complicated mystery with many players, the main suspects being chemical. However, a new study by University of Illinois researchers and collaborators in China ...
