Further evidence for the involvement of antioxidants in the proliferation of cancer. They are the ones that help the cancer cells to survive "This paper reveals that cancer cells that are detached from their normal environment, as they would be during metastasis, relay on the activity of antioxidant enzymes to facilitate their survival," Schafer said. "This class of enzymes is critical for neutralizing oxidative stress and function much like the compounds that are present in a variety of foods." The paper describes a prominent role for antioxidant enzymes in facilitating the survival of breast cancer cells after detachment from the extracellular matrix. Conversely, the researchers report, silencing antioxidant enzyme expression reduced tumor formation. "The results in this paper suggest that targeting antioxidant enzymes with novel therapeutics may selectively kill off metastasizing cancer cells," Schafer said.
