There is an ongoing interest in cellular antioxidants and oxidants as well as
cellular mechanisms underlying their effects. Several reports suggest that
vitamin C (L-ascorbic acid) functions as a pro-oxidant with selective toxicity
against specific types of tumor cells. In addition, reduced glutathione plays an
emerging role in reducing oxidative stress due to xenobiotic toxins such as
metals and oxidants associated with diseases such as cancer, cardiovascular
disease, and stroke. High-dose intravenous vitamin C and intravenous glutathione
have been used as complementary, alternative, and adjuvant medicines. Here, we
review the molecular mechanisms underlying the regulation of oxidation/reduction
systems, focusing on the altered metabolomics profile in cancer cells following
treatment with pharmacological vitamin C. This review focuses on the role of
vitamin C in energy metabolism in terms of adenosine triphosphate, cysteine, and
reduced glutathione levels, affecting cancer cell death.
