Tiny pieces of gold could be used in the battle against cancer, new research has indicated.
Scientists at Edinburgh University discovered the precious metal advanced the effectiveness of drugs used to treat lung cancer cells. This could be a tactic that we see a lot of biotech stocks start to implement into their treatments. Minute fragments, also known as gold nanoparticles, were enclosed in a chemical by the research team.
The research entailed zebrafish but the team are optimistic the technique could be used to develop human treatments. Gold is a safe element that can speed up chemical reactions. It is yearned that specifically targeted diseased cells could in fact one day use this method to diminish side effects of current chemotherapy treatments without damaging healthy tissue.
Dr Asier Unciti-Broceta, from Cancer Research UK’s Edinburgh centre, stated: “We have discovered new properties of gold that were previously unknown and our findings suggest that the metal could be used to release drugs inside tumours very safely.”
“There is still work to do before we can use this on patients, but this study is a step forward. We hope that a similar device in humans could one day be implanted by surgeons to activate chemotherapy directly in tumours and reduce harmful effects to healthy organs,” she added.
Dr Aine McCarthy, Cancer Research UK’s senior science information officer, quoted: “By developing new, better ways of delivering cancer drugs, studies like this have the potential to improve cancer treatment and reduce side effects.”
“In particular, it could help improve treatment for brain tumours and other hard-to-treat cancers. The next steps will be to see if this method is safe to use in people, what its long and short-term side effects are, and if it’s a better way to treat some cancers,” she concluded.
The study was conducted in partnership with researchers at the University of Zaragoza’s Institute of Nanoscience of Aragon in Spain and published in the scientific journal Angewandte Chemie.
