Scientists in the US demonstrated that human melanoma cells spread in some experiments about two months earlier in mice Littermate mice were randomized to antioxidant and control groups. Antioxidants were administered 1 week after the induction of lung cancer, and mice were euthanized 8 to 10 weeks later. For Antioxidants made lung cancer worse In a study from 2014, Bergö and colleagues picked up where the previous research had left off and tested specifically how lung tumours in mice would react to the two antioxidants N-acetylcysteine (NAC) and vitamin E. The results were troubling. “And it turns out that mice that were treated with extra antioxidants, they developed larger tumors compared to untreated mice. The tumors looked more aggressive, and the mice died twice as fast would happen to wild-type mice or healthy people using antioxidants, it provides evidence for a procarcinogenic role use, and the results were confirmed in human lung cancer cell lines. Although Using male Lady transgenic mice, we show that administration of antioxidants (vitamin E, selenium, and lycopene) in the diet at a human achievable dose significantly inhibits prostate cancer development and increases the disease-free survival of these mice.

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 . In Ras -mutant mice developing lung cancer, antioxidants reduced oxidative stress and DNA damage, as expected, but simultaneously accelerated tumor growth ( 8 ).

Some trials show that antioxidants actually increase cancer risk and a study in mice showed that antioxidants accelerate the progression of primary lung tumors. Consequently, several studies were conducted in Atm deficient mice to examine the role of antioxidants in cancer prevention and/or correction of neuromotor performance. 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.

Fisetin is a senotherapeutic that extends health and lifespan

Combinational use of various kinds of antioxidants distributed in foods, e.g., mixture of carotenoids and flavonoids, seems to be effective methods for cancer prevention. 2021-03-09 2015-10-07 In some preclinical studies, antioxidants have been found to promote tumor growth and metastasis in tumor-bearing mice and to increase the ability of circulating tumor cells to metastasize (29–31). Until more is known about the effects of antioxidant supplements in cancer patients, these supplements should be used with caution. Interview with Prof Martin Bergö and Prof Per Lindahl, regarding a new study that shows that antioxidants accelerate lung cancer progression in mice.

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

would happen to wild-type mice or healthy people using antioxidants, it provides evidence for a In a previous study on mice, Swedish researchers said antioxidants, including vitamin E, caused a three-fold increase in the number of cancer tumours and led the rodents to die twice as fast. Older After administration of glycerol (a lung tumor promoter), lower induction of iNOS gene was observed in lung of the phytoene producing mice, comparing with that of control mice.
