New technology uses UV light to fight cancer

This news item was added on 23rd October 2007

UV light is well-known for being a key factor in skin cancer, but researchers at Newcastle University have now developed a way of using it to target tumours.

The new technology uses UV light to activate antibodies that specifically attack tumours without harming healthy tissue.

The antibodies are 'cloaked' in a protective oil that prevents them from working unless they are activated by shining a UV-A light on the specific area of the body.

Newcastle University researcher Professor Colin Self described the treatment as "the equivalent of ultra-specific magic bullets" and said that it opens up many possible applications.

"This is therefore a very specific treatment and while our work indicates that sunlight doesn't activate these antibodies, patients may have to be advised to avoid direct sunlight for a short period after treatment," he added.

Cancer Research UK has welcomed the research, which is published in the journal ChemMedChem.

"Developing treatments that attack cancer cells but leave healthy tissue unharmed is the holy grail of cancer research," said senior science information officer Josephine Querido.

"Although at a very early stage, this new approach has potential, and we await the outcome of further research with interest."
