SOLID GOLD: In a study recently published in the Proceedings of the National Academy of Sciences, a team of MU scientists described how gold nanoparticles (pictured) and a tea leaf-based compound could potentially treat prostate tumors with doses that are much smaller and far less damaging than conventional chemotherapy. In the study, the researchers discovered that a special compound in tea was attracted to tumor cells in the prostate. When they combined the tea compound with radioactive gold nanoparticles, the tea compound helped ‘deliver’ the nanoparticles to the site of the tumors, where the nanoparticles destroyed the tumor cells “very efficiently.” The finding, like the early-stage research results detailed on Page 4, represents another important step toward taming a form of cancer that kills thousands of men each year.
