摘要
Background: Neuropeptide Y ( NPY), agouti related peptide ( AgRP), cocaine and amphetamine-regulated transcript ( CART) and melanocortins, the products of the proopiomelanocortin ( POMC), are hypothalamic peptides involved in feeding regulation and energy homeostasis. Recent evidence has demonstrated their expression in rat and human placenta. Methods: In the current study, we have investigated the expression of those neuropeptides in the rat placenta by real-time PCR using a model of maternal food restriction. Results: Our results showed that placental-derived neuropeptides were regulated through pregnancy and following food restriction. Conclusion: These data could indicate that placental-derived neuropeptides represent a local regulatory circuit that may fine-tune control of energy balance during pregnancy.
