Spice link to improved cancer treatment
A CURRY spice ingredient can encourage ovarian cancer to be more responsive to treatment.
American researchers pre-treated ovarian tumours with curcumin, a component of the spice turmeric, delivered in the form of microscopic "nanoparticles". Curcumin sensitised the cancer tissue, making it more vulnerable to chemotherapy and radiation treatment.
Study leader Dr Subhash Chauhan, from the University of South Dakota, said:
"We have developed a nanoparticle formulation to provide increased bioavailability as well as targeted delivery into tumours."
The formulation was tested on therapy-resistant cells in the laboratory. Pre-treatment was found to lower the doses needed to suppress growth.
