Thus, antioxidants accelerate tumor growth by disrupting the ROS-p53 axis. A study in mice has found that two commonly used antioxidants — vitamin E and a compound called N-acetylcysteine (NAC) — speed the growth of lung cancer rather than curb it. Treating these mice with antioxidants decreased oxidative stress in the circulating cancer cells and increased their ability to metastasize. “Administration of antioxidants to the mice allowed more of the metastasizing melanoma cells to survive, increasing metastatic disease burden,” Dr. Morrison said in a press release.

Antioxidanter är för de flesta av oss kända för att skydda våra celler. Detta eftersom de neutraliserar så kallade fria radikaler, som gör att cellerna ”rostar”.
