Small stretches of DNA in the human genome are known as "pseudogenes." They are called so because, while their sequences are nearly identical to those of various genes, they have long been thought to be non-coding "junk" DNA.
But now, a new study led by scientists at The Scripps Research Institute (TSRI) shows how pseudogenes can regulate the activity of a cancer-related gene called PTEN. The study also shows that pseudogenes can be targeted to control PTEN's activity.
