[The role of melatonin in the molecular mechanism of weak, static and extremely low frequency (50 Hz) magnetic fields (ELF)].
Melatonin is a neurohormone produced by the pineal gland. It has been recently found that it is also an antioxidant and a free radical scavenger. Melatonin was documented to be a direct trap of hydroxyl and peroxyl radicals. Therefore, this hormone could protect cells, tissues and organs against oxidative (free radicals) damage (DNA, protein, lipids). It has been suggested that noxious effects of ELF exposure (cancer or immunological disturbances) could be due to increased the concentration of free radicals induced by magnetic field. This is also leading to a hypothesis that melatonin suppression (by electromagnetic fields) in humans may increase the probability of mutagenic and carcinogenic risks. The future experiments, in vitro and in vivo, should provide an answer to the question on what is the real role of melatonin in the molecular (free radicals) mechanisms of weak magnetic fields.
