TEXAS, USA, July 11, 2005: Curcumin, the yellow pigment found in the curry spice turmeric, inhibits melanoma cell growth and kills tumor cells, shows a new study. Previous studies have already demonstrated that the spice has an anti-cancer effect. The new research, published online today (here) and scheduled for the 15 August print issue of Cancer, also reveals how curcumin acts against this type of tumor. Researchers led by Razelle Kurzrock of the University of Texas Anderson Cancer Center in Houston treated three melanoma cell lines with curcumin at different doses and for different duration. Results show that curcumin treatment decreased cell viability in all three cell lines in a dose-dependent manner. Epidemiological studies have linked high consumption of turmeric to lower rates of breast cancer, prostate cancer, lung cancer and colon cancer.
