New study on circadian clock shows 'junk DNA' plays a key role in regulating rhythms

Researchers have been trying to figure out what regulates molecular circadian clocks, in search of new insights into diseases like Alzheimer's, cancer and diabetes. Until now, that research has focused on what is known as clock genes. But new research reveals the discovery of a new cog in the circadian clock - a genome-wide regulatory layer made up of small chains of non-coding nucleotides known as micro RNAS (miRNAs).
