Scientists have discovered a new way genes are regulated that is unique to primates. Long-known, but little-understood DNA elements serve important purpose, according to new research. The newly identified mechanism involves Alu elements, repetitive DNA elements that spread throughout the genome as primates evolved. While scientists have known about the existence of Alu elements for many years, their function, if any, was largely unknown. This unique regulatory mechanism could prove to be a valuable treatment target as researchers seek to manipulate gene expression to improve human health.
