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

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. Antioxidants, such as vitamin C (above) and E, are widely consumed as dietary supplements for their supposed anti-cancer benefits. New research in mice suggests that certain antioxidants can Cancer cells produce high levels of mitochondria-associated reactive oxygen species (ROS) that can damage macromolecules, but also promote cell signaling and proliferation. Therefore, mitochondria-targeted antioxidants have been suggested to be useful in anti-cancer therapy, but no studies have convincingly addressed this question. Here, we administered the mitochondria-targeted antioxidants 2019-10-03 2015-10-17 2018-07-14 2020-07-30 The use of antioxidants during cancer therapy has been a hot topic in medical science for the last 20 years without clear answers and recommendations. It seems that antioxidants are able to I) decrease the cancer formation risk by quenching ROS that are involved in cancer initiation and progression and II) assist in survival of cancer/precancer cells once the malignant transformation already 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. 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 say.

Interview with Prof Martin Bergö and Prof Per Lindahl, regarding a new study that shows that antioxidants accelerate lung cancer progression in mice. The fin The work, conducted in mice, shows that antioxidants can change cells in ways that fuel the spread of malignant melanoma—the most serious skin cancer—to different parts of the body. The progression 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. mice with B-RAF– and K-RAS–induced lung cancer by reducing ROS, DNA damage, and p53 ( 7).

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 ).

Therefore, mitochondria-targeted antioxidants have been suggested to be useful in anti-cancer therapy, but no studies have convincingly addressed this question. Here, we administered the mitochondria-targeted antioxidants Reactive oxygen species (ROS) play important roles in tissue homeostasis, cellular signaling, differentiation, and survival. In this review, we discuss the types of ROS, their impact on cellular processes, and their pro- and antitumorigenic effects. Further, we discuss recent advances in our understanding of both endogenous and exogenous antioxidants in tumorigenic processes.
