Although 2015-10-08 2019-07-01 PARIS — Antioxidant supplements that are supposed to boost health and slow ageing could in fact spur the spread of melanoma, the deadliest type of skin cancer, researchers said on Wednesday. The findings support recent studies showing that an over-the-counter vitamin and another drug containing antioxidants can cause a jump in the number of tumors and hike their aggressiveness. 2019-12-09 They are now doing similar experiments in melanomas, leukaemias, and gastrointestinal tumors to see whether the same mechanisms hold true for other types of cancer. V.I. Sayin et al., “Antioxidants accelerate lung cancer progression in mice,” Science Translational Medicine, 6: 221ra15, 2014.

Därför har man utgått ifrån att antioxidanter håller cellerna friska och skyddar oss mot bland annat cancer. The new studies, which the researchers carried out using human tissue and mice, reveal how lung cancer cells use antioxidants to withstand oxidative stress and thrive. A study by Swedish researchers reported recently in Science Translational Medicine shows that two antioxidants— N -acetylcysteine and vitamin E—accelerate the progression of early lung tumors in mice and in human lung cancer cell lines. 2019-12-08 · Dr. Lawenda’s Experiment (EGCG, Vitamin E, Breast Cancer, Mice, Radiation Therapy) During Dr. Lawenda’s residency, he conducted a study at the USDA’s Antioxidant Research Laboratory, to explore whether vitamin E or green tea would interfere with the effect of radiation therapy on tumors . 2019-10-03 · Antioxidants have been suggested to increase the risk of developing several forms of cancer in humans (5 – 7) and to accelerate lung tumor progression in murine models of lung cancer .

Although The antioxidants appear to boost cancer progression by decreasing the amount of a key tumor suppressor protein called p53. "When we knocked out p53 in the mice and in human lung cancer cell lines, the antioxidants had no effect," said Bergö. Antioxidants stimulate cancer progression.

The results reinforce previous findings that antioxidants hasten the progression of lung cancer.

However, little is known about the impact of antioxidant supplementation on the progression of other types of cancer, including malignant melanoma. 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. N-acetyl-l-cysteine (NAC), EUK-189, tempol, and 5-carboxy-1,1,3,3-tetramethylisoindolin-2-yloxyl (CTMIO) have been tested in Atm deficient mice.
