PURPOSE: Endocan is a proteoglycan secreted mainly from endothelial cells. It has been implicated that there is a link between endocan and endothelial dysfunction. Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disease associated with increased risk of cardiovascular events. The aims of this study were to ascertain whether circulating endocan levels are altered in women with PCOS, and whether there is an association between endocan and carotid intima media thickness (cIMT)...

Classic features of polycystic ovary syndrome (PCOS) include derangement of metabolic and cardiovascular health, and vascular dysfunction is commonly reported. These comorbidities indicate impaired blood flow; however, other than limited reports of increased plasma viscosity, surprisingly little is known regarding the physical properties of blood in PCOS. We aimed to investigate whether haemorheology was impaired in women with PCOS. We thus measured a comprehensive haemorheological profile, in a case-control design, of lean women with PCOS and age-matched healthy controls...

Polygenic diseases with a broad phenotypic spectrum, such as polycystic ovary syndrome (PCOS), present a particular challenge in terms of identifying the underlying genetic mechanisms, nevertheless genetic variants have impact on the individual phenotype. We aimed to determine if next to genetic variations like SNPs further mechanisms might play a role in the pathogenesis of PCOS. We examined the effect of copy-number variations (CNVs) on metabolic phenotypes in PCOS. The intragenic rs1244979, rs2815752 in NEGR1 gene, and rs780094 in GCKR gene were genotyped and CNVs were determined by droplet digital polymerase chain reaction (ddPCR) in PCOS patients (n = 153) and controls without metabolic syndrome (n = 142)...

Ovarian aging is associated with gradual follicular loss by atresia/apoptosis. Increased production of toxic metabolites such as reactive oxygen species (ROS) and reactive nitrogen species as well as external oxidant agents plays an important role in the process of ovarian senescence and in the pathogenesis of ovarian pathologies such as endometriosis and polycystic ovary syndrome (PCOS). This review provides a synthesis of available studies of oxidative stress (OS) in the ovary, focusing on the most recent evidence obtained in mural granulosa-lutein (GL) cells of in vitro fertilization patients...

BACKGROUND: Metabolic syndrome (MetS) is a cluster of risk factors which increase the risk of developing cardiovascular diseases and type II diabetes mellitus. High blood pressure, hyperglycemia, dyslipidemia, and central obesity are the main risk factors. While MetS is not a dermatological diagnosis per se, several cutaneous manifestations can serve as a clinical indicator for impending MetS and facilitate an early diagnosis and therapy in order to prevent its long-term sequelae...

Obesity and insulin resistance (IR) are frequently present in patients with polycystic ovary syndrome (PCOS). Both disorders also play an important role in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). Accordingly, NAFLD is frequently present in patients with PCOS. In the present review, we summarize the findings of the major studies that assessed the prevalence of NAFLD in patients with PCOS. The factors driving the increased frequency of NAFLD in patients with PCOS are also analyzed. Finally, we discuss the management options of NAFLD in patients with PCOS...

Obesity and its metabolic complications have emerged as the epidemic of the new millennia. The use of obese rodent models continues to be a productive component of efforts to understand the concomitant metabolic complications of this disease. In 1978, the JCR:LA-cp rat model was developed with an autosomal recessive corpulent (cp) trait resulting from a premature stop codon in the extracellular domain of the leptin receptor. Rats that are heterozygous for the cp trait are lean-prone, while those that are homozygous (cp/cp) spontaneously display the pathophysiology of obesity as well as a metabolic syndrome (MetS)-like phenotype...
