Programmed cell death and melatonin: A comprehensive review.

Melatonin (MLT), a main product of pineal gland, recently has attracted the attention of scientists due to its benefits in various diseases and also regulation of cellular homeostasis. Its receptor scares widely distributed indicating that it influences numerous organs. Programmed cell death (PCD), of which there several types, is a regulated by highly conserved mechanisms and important for development and function of different organs. Enhancement or inhibition of PCDs could be a useful technique for treatment of different diseases and MLT, due to its direct effects on these pathways, is a good candidate for this strategy. Many studies investigated the role of MLT on PCDs in different diseases and in this review, we summarized some of the most significant studies in this field to provide a better insight into the mechanisms of modulation of PCD by MLT modulation.
