Vitamin C and Cancer
Vitamin C or ascorbic acid has been proposed as an anticancer agent, as an intervention to reduce cancer incidence, and also as a medication to reduce cancer treatment-related side effects. While there has been significant basic science research that has evaluated the potential tumoricidal mechanisms of action, clinical studies have been underpowered, retrospective, or poorly designed. Current ...
متن کاملVitamin C Against Cancer
The selective anticancer properties of vitamin C are known since at least four decades. However, only recently in vitro studies have shown that vitamin C, in high enough concentrations, can efficiently and selectively kill a number of different human tumor cell lines, and these data have been confirmed in experimental animal tumor models. The first human clinical trials revealed that high doses...
متن کاملVitamin C and cancer revisited.
I n this issue of PNAS, Chen et al. (1) show that i.p. injection of ‘‘pharmacologic doses’’ of vitamin C decreases the growth and weight of human, rat, and murine tumor xenografts in athymic, nude mice. This work follows a number of articles by the same group, led by Mark Levine at the National Institute of Diabetes and Digestive and Kidney Diseases, showing that millimolar concentrations of ex...
متن کاملVitamin C Doesn't Cause Cancer!
A study in a recent issue of the highly respected journal Science reported that lipid hydroperoxides (rancid fat molecules) react with vitamin C to form products that could potentially harm DNA. Although the reaction of these products with DNA was not demonstrated in the study, the authors suggested that vitamin C can form genotoxins (DNA-damaging agents) from lipid hydro-peroxides, titling the...
متن کاملVitamin C Intakes and Prostate Cancer Risk
Background: Vitamin E, β -carotene, and vitamin C are micronutrient antioxidants that protect cells from oxidative damage involved in prostate carcinogenesis. In separate trials, supplemental vitamin E was associated with a decreased risk of prostate cancer among smokers and supplemental β -carotene was associated with a decreased risk of prostate can cer among men with low baseline plasma β -c...
