Novel regulator of key gene expression in cancer identified

A key genetic switch linked to the development, progression and outcome of cancer has been discovered by scientists, a finding that may lead to new targets for cancer therapies. The switch, a string of nucleotides dubbed a long non-coding RNA (lncRNA), does not code for proteins like regular RNA. Instead, the scientists found, this particular lncRNA acts as an on/off switch for a key gene whose excessive activity is tied to inflammation and cancer, COX-2.
