Curcumin “helps cancer treatment”

teaser

A curry spice ingredient has been successful in the pre-treatment of ovarian cancer, research has shown.

Scientists from the University of South Dakota, US, discovered that curcumin, a component of the yellow spice turmeric, sensitised the cancer tissue, making it more responsive to radiation therapies.

The team developed a “nanoparticle” curcumin formulation – called Nano-CUR – and tested previously therapy-resistant cancer cells.

Study leader Dr Subhash Chauhan said: “One strategy to improve the effectiveness and limit the toxicity of cancer therapy is to induce chemo/radio-sensitisation in cancer cells using natural dietary phytochemicals like curcumin. However, curcumin is poorly absorbed by the body which limits its effectiveness.

“We have developed a nanoparticle formulation, Nano-CUR, to provide increased bioavailability as well as targeted delivery of curcumin into tumours.”

Pre-treatment was found to lower the doses of treatment needed to suppress the cancerous growth.

Dr Chauhan said: “Nanoparticle mediated curcumin delivery will further improve the sensitisation and therapeutic capabilities. This study demonstrates a novel pre-treatment strategy that could be implemented in pre-clinical animal models and in future clinical trials.”

The findings were published online in the Journal of Ovarian Research.
