Human genes are written in long strings of three-letter units composed of four different nucleotides. These units—or ...

Cells rely on tiny molecules called microRNAs to tune which genes are active and when. Cells must carefully control the lifespan of microRNAs to prevent widespread disruption to gene regulation. A new ...

A new study shows cells use dual RNA signals to control microRNA lifespan. This selective process protects gene regulation while enabling targeted RNA breakdown.

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 ...

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 ...

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, ...

Learn about epigenetic studies related to Alzheimer's disease in Mayo Clinic's Precision Medicine in Neurodegeneration Lab led by Nilufer Ertekin-Taner, M.D., Ph.D.

A collaborative effort has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of ...

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 ...

A study has traced thousands of conserved regulatory elements back 300 million years, revealing deep principles of plant ...
