Abstract—Vitamin B12, or cobalamin, is essential for normal body function and is used in the therapies of different diseases. Vitamin B12 has anti-inflammatory and antioxidant properties that can play an important role in the prevention of some diseases. On the other hand, it has been reported that vitamin B12 in combination with such reducing agents as ascorbate (vitamin C) and thiols showed prooxidant activity. This review provides information on the roles of vitamin B12 in diseases accompanied by inflammation and oxidative stress and the effects of vitamin B12 administrated alone and in combinations with different reducing agents such as ascorbate and thiols on oxidative stress. In addition, the mechanisms of prooxidant actions of combinations of vitamin B12 with these reducing agents depending on the form of vitamin B12 (hydroxocobalamin and cyanocobalamin) are discussed. Understanding the mechanisms of prooxidant action of vitamin B12 is necessary for developing strategies for therapeutic administration of vitamin B12.
期刊介绍：
Molecular Biology is an international peer reviewed journal that covers a wide scope of problems in molecular, cell and computational biology including genomics, proteomics, bioinformatics, molecular virology and immunology, molecular development biology, molecular evolution and related areals. Molecular Biology publishes reviews, experimental and theoretical works. Every year, the journal publishes special issues devoted to most rapidly developing branches of physical-chemical biology and to the most outstanding scientists.
