New research could pave the way to safer treatments for arthritis
Date:7/4/2013

added: "This study does not provide all the answers, but once we understand exactly how COX-2 affects the cardiovascular system we will be in a position to design new therapies. This will not be easy but all the tools are available and we could be looking at new leads within five to ten years."

In order to accurately measure concentrations of COX-2 within the body, the researchers used mice whose COX-2 gene had been replaced with a gene called luciferase, which gives fireflies their distinctive glow. This allowed researchers to create detailed images of the distribution of COX-2 throughout the body.

Professor Anna Nicolaou, a co-author, now at the University of Manchester, said: "This study is the first to use such sophisticated techniques to determine the locations of COX-2 within the body. The use of mass spectrometry and genetically modified mice in this way represents a significant advance in the field."

This was echoed by Professor Tim Warner, a co-author from Queen Mary, University of London, who said: "These cutting edge techniques are at last supplying us with the definitive answers we need to understand the side effects of arthritis drugs. This could help improve therapy for many millions of patients worldwide."
