RT Journal Article T1 Neonatal events, such as androgenization and postnatal overfeeding, modify the response to ghrelin A1 Garrido Novelle, Marta A1 Vázquez, María A1 Martinello, Kátia A1 Sánchez-Garrido, Miguel A1 Tena-Sempere, Manuel A1 Diéguez, Carlos AB It is currently accepted that ambient, non-genetic factors influence perinatal development and evoke structural and functional changes that may persist throughout life. Overfeeding and androgenization after birth are two of these key factors that could result in “metabolic imprinting” of neuronal circuits early in life and, thereby, increase the body weight homeostatic “set point”, stimulate appetite and result in obesity. Our aim was to determine the influence of these obesogenic factors on the response to ghrelin. We observed the expected orexigenic effect of ghrelin regardless of the nutritional or hormonal manipulations to which the animals were subjected to at early postnatal development and this effect remained intact at later stages of development. In fact, ghrelin responses increased significantly when the animals were subjected to one of the two manipulations, but not when both were combined. An increased response to ghrelin could explain the obese phenotype displayed by individuals with modified perinatal environment.
