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

Precision and timing of gene expression is essential for normal biological functions and, when disrupted, can lead to many human diseases, including cancers. However, how molecular machines—protein ...

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 ...

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 new study shows cells use dual RNA signals to control microRNA lifespan. This selective process protects gene regulation ...

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

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 ...

What if you could flip a genetic switch to silence a gene, then turn it back on with a simple drug? For researchers, gene-switch tools offer that kind of control—and a new system called Cyclone may ...

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 ...

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 ...

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 ...
