title: A review of the use of melatonin in ulcerative colitis: experimental evidence and new approaches.
abstract: : Ulcerative colitis (UC), an inflammatory bowel disease, affects many people across the globe, and its prevalence is increasing steadily. Inflammation and oxidative stress play a vital role in the perpetuation of inflammatory process and the subsequent DNA damage associated with the development of UC. UC induces not only local but also systemic damage, which involves the perturbation of multiple molecular pathways. Furthermore, UC leads to an increased risk of colorectal cancer, the third most common malignancy in humans. Most of the drugs used for the treatment of UC are unsatisfactory because they are generally mono-targeted, relatively ineffective and unaffordable for many people. Thus, agents that can target multiple molecular pathways and are less expensive have enormous potential to treat UC. Melatonin has beneficial effects against UC in experimental and clinical studies because of its ability to modulate several molecular pathways of inflammation, oxidative stress, fibrosis, and cellular injury. However, many novel targets are yet to be explored on which melatonin may act to exert its favorable effects in UC. It is time to explore improved intervention strategies with melatonin in UC on the basis of studies investigating different molecular targets using proteomic and genomic approaches. This review identifies various molecular targets for melatonin with the intent of providing novel strategies for combating UC and the associated extraintestinal manifestations of this debilitating disease.
