The data also indicates that mitochondr ia-targeted antioxidants do not inhibit cancer progression. These results suggest that cancer patients and people with high risk of developing cancer should avoid the use of antioxidant supplements.

Oxidative stress is a key component in linking environmental toxicity to the multistage carcinogenic process. Reactive oxygen species (ROS) are generated in response to both endogenous and exogenous stimuli. To counterbalance ROS-mediated injury, an endogenous antioxidants defense system exists; how …. We assessed the separate relationships of three antioxidants (carotenoids, vitamin C, and vitamin E) with six sites of cancer (lung, upper aerodigestive tract, uterine cervix, colon, breast, prostate). This review was limited to dietary intake or serum nutrient studies that met a predefined set of methodologic standards. 2001-10-01 Dietary antioxidants and the aetiology of pancreatic cancer: a cohort study using data from food diaries and biomarkers.

METHODS: The extent of lipid peroxidation as evidenced by the formation of thiobarbituric acid reactive substances (TBARS) and conjugated dienes (CD) as well as the status of the antioxidants superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH), glutathione peroxidase (GPx) and glutathione S-transferase (GST) in serum samples of 40 breast cancer patients in and around Oxidative stress has been related to cardiovascular disease, cancer, and other chronic diseases that account for a major portion of deaths today.

2016-09-21 · Purpose Many patients with cancer take antioxidant nutritional supplements during cancer treatment to alleviate treatment toxicities and to improve long-term outcomes, but little is known about the efficacy and safety of antioxidant use during cancer treatment. We reviewed English-language manuscripts published in the biomedical literature, reporting the results of observational studies of In this Special Issue of Antioxidants, “Antioxidants in Cancer”, experts are invited to contribute original research papers or review articles that will provide insights into the role of antioxidants in cancer treatment and prevention.

[PubMed abstract] Antioxidants, an international, peer-reviewed Open Access journal.

The notion of cancer prevention through antioxidant intervention arises from the fact that fruits and vegetables contain antioxidants and are linked to low cancer rates in those who consume them. Protection against DNA damage by plant food products can be demonstrated in vitro. 2014-03-15 · This review focuses on the roles antioxidants and pro-oxidants in colorectal cancer (CRC). Considerable evidence suggests that environmental factors play key roles in the incidence of sporadic CRC. If pro-oxidant factors play an etiological role in CRC it is reasonable to expect causal interconnections between the well-characterized risk factors for CRC, oxidative stress and genotoxicity.

A number of antioxidants have shown to inhibit the induction of cancer by a wide variety of chemical carcinogens and/or radiation at many target sites in mice, rats, and hamsters. Epidemiological studies suggest that a diet rich in plant products containing natural antioxidants may be a deterrent to carcinogenicity.

The purpose of this review is to survey the literature on modern biological theories of cancer and the roles of dietary antioxidants in cancer. The roles and functions of antioxidant micronutrients, such as vitamin C (ascorbate), vitamin E (alpha-tocopherol), selenium, and vitamin A, provided through diet for the prevention of cancer are discussed in the present work.

Antioxidants accelerate lung cancer progression in mice. Science Translational Medicine 2014; 6(221):221ra15. [PubMed Abstract] Le Gal K, Ibrahim MX, Wiel C, et al. Antioxidants can increase melanoma metastasis in mice. Tvärtom fick flera studier avbrytas för att det verkade som om de som åt kosttillskott oftare fick cancer. 2014 var vi först med att visa att antioxidanter skyddar både friska celler och cancerceller, vilket innebär att om man har cancer kan de påskynda utvecklingen och spridningen. Det har visats både för lungcancer och melanom.
