Abstract

The aim of this work is to study the role played by melatonin in the control of energy metabolism. Using in vivo and in vitro experiments, in intact or pinealectomized young or old animais, treated or not with melatonin, we are proposing to study the metabolic function and gene expression in the white adipose tissue, skeletal muscular system and the pancreatic B cells and the apoptosis phenomenon induced by fatty acids. Moreover, we intend to study the action of melatonin in association or not with insulin and/or leptin on cellular metabolism and gene expression in specific hypothalamic nuclei or in neurons and/or glia cells maintened in culture. The central nervous system structures to be studied are those mainly involved in the control of energy metabolism and the control of circadian rhythms. (AU)
