Scientists at the MRC Laboratory of Medical Sciences (LMS) have discovered a DNA-based “dimmer switch” that regulates the activity of a critical developmental gene, Cdx2. This work could pave the way ...

Scientists usually study the molecular machinery that controls gene expression from the perspective of a linear, two-dimensional genome—even though DNA and its bound proteins function in three ...

To help achieve more precise control of gene therapy, engineers have designed a new control circuit that can keep gene expression levels within a target range. The method could be used to deliver ...

To further the quantitative understanding of cellular decision making, Dr. Gregory Reeves and his team in the chemical engineering department have worked to interpret how a transcription factor ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Turning genes on and off is like flipping a light switch, controlling whether genes in a cell are active. When a gene is turned on, the production of proteins or other substances is promoted; when ...

Learn about comparative gene expression studies in Alzheimer's disease and other conditions in Mayo Clinic's Precision Medicine in Neurodegeneration Lab.

Long non-coding RNAs (lncRNA) are a type of RNA molecule that do not carry instructions to make proteins. Instead, they influence how other genes are expressed. There are tens of thousands of lncRNAs ...

The expression of genes has to be carefully regulated in cells; active genes give cells their identity and ability to function. Epigenetic features are just one way that cells control gene expression, ...

A newly released publication examines how deuterium concentration may influence gene activity in lung cancer cells. The study explores how shifts in this ...

Our circadian clocks play a crucial role in our health and well-being, keeping our 24-hour biological cycles in sync with light and dark exposure. Disruptions in the rhythms of these clocks, as with ...
