Objective(s): Atherosclerosis is an important risk factor for coronary heart disease. Neuropeptide Y (NPY) and its receptors, located in peripheral tissue such as white adipose tissue, have been linked to obesity and fat storage. The role of NPY in atherosclerosis has not yet been fully studied, so this study was conducted to further investigate the effect of BIIE 0246, an NPY receptor antagoni...

Several studies have shown that neuropeptide Y (NPY) is considered to be one of the key regulators of the hypothalamic-pituitary-gonadal axis in the mammals. Also, kisspeptin is a powerful upstream regulator of gonadotropin-releasing hormone neurons in the hypothalamus. The present study aims to investigate the effects of the intracerebroventricular (ICV) injection of NPY and BIBP3226 (NPY rece...

introduction: numerous studies have demonstrated that kisspeptin, a peptide from the kiss1 gene, plays an important role in regulating the secretion of gonadotropin releasing hormone (gnrh). also, there is some evidence suggesting that kisspeptin can interact with other neuropeptides for the control of the reproductive axis. in the present study, we have investigated the effect of central admin...

Introduction: Neuropeptide Y (NPY) is the most abundant peptide present in mammals' brains. The majority of NPY-producing neurons is in arcuate and paraventricular nuclei of hypothalamus which affect hypophysiotrapic factors secretion. In this study we investigated the effect of intravenous injections of various doses of NPY on thyroxine (T4) and triiodothyronine (T3) serum concentrations. ...

Neuropeptide Y (NPY) is a 36 amino acid peptide found throughout the central and peripheral nervoussystem of rat and human. NPY has been proposed to play an important role in satiety. The aim of this studywas to produce cell lines that secrete high levels of bioactive NPY. For this purpose, the complementaryDNA (cDNA) that encodes NPY was isolated by PCR. The cDNA was then clo...
