Physical force alone spurs gene expression

April 3, 2020

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 faster than chemical signals can travel, the researchers report.

The scientists tested forces that are biologically relevant - equivalent to those exerted on human cells by breathing, exercising or vocalizing. They report their findings in the journal Science Advances.
