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 ...

Researchers identified DHX29 as a key protein that detects non-optimal codons and represses inefficient mRNAs, revealing how ...

A newly identified cellular system monitors subtle variations in genetic coding, hinting at a hidden level of control over ...

Cells rely on tiny molecules called microRNAs to tune which genes are active and when. Cells must carefully control the ...

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 recent study marks the first reported instance of generative AI designing synthetic molecules that can successfully control gene expression in healthy mammalian cells. As a proof-of-concept, the ...

For decades, biologists have known that the instructions for life are written in DNA, yet the vast majority of those letters seemed to sit in the dark, doing little that was obvious. Now a new ...

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 ...

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 ...

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 ...
