Nesfatin-1 a recently discovered hormone, acts upon energy balance, glucose metabolism, obesity and probably gonadal functions. This study was to evaluate the circulating levels of nesfatin-1 in patients with PCOS (n = 30) and in age and body mass index (BMI)-matched controls (n = 30). PCOS patients had significantly lower levels of nesfatin-1 (0.88 ± 0.36 ng/mL) than healthy controls (2.22 ± 1.14 ng/mL). PCOS patients also had higher gonadotropin and androgen plasma concentrations, Ferriman-Gallwey scores, blood glucose levels and a homeostasis model of assessment-IR index (HOMA-IR) index than in healthy women. Correlation tests in PCOS subjects detected a negative correlation between nesfatin-1 levels and BMI, fasting blood glucose, insulin levels and a HOMA-IR index. Lower nesfatin-1 concentration may plays a very important role in the development of PCOS. © 2012 Springer Science+Business Media, LLC.</dc:description><dc:publisher>Humana Press Inc.</dc:publisher><dc:date>2012</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/15573</dc:identifier><dc:identifier>https://doi.org/10.1007/s12020-012-9638-7</dc:identifier><dc:identifier>1355-008X</dc:identifier><dc:language>en</dc:language><dc:relation>Endocrine</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/15573</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
