... The energy-sensing protein SIRT1 is an important regulatory protein that can prolong the life span of model organisms such as yeast and fruit flies. In humans, SIRT1 is possibly involved in the regulation of energy use. The SIRT1 activity can be simulated by various polyphenols. De Boer discovered that polyph...Fly and worm models to teach researchers about human biology and medicine

Researchers now know that junk DNA may contain regulatory elements that influence the activity of nearby genes, but the full extent of the importance of these non-gene regions is still being revealed.

It is unusual to find a regulatory gene so close to the gene it regulates, the researchers noted.
