SET (SE Translocation) protein carries out multiple functions including those for protein phosphatase 2A (PP2A) inhibition, histone modification, DNA repair, and gene regulation. SET overexpression has been detected in brain neurons of patients suffering Alzheimer's disease, follicle theca cells of Polycystic Ovary Syndrome (PCOS) patients, and ovarian cancer cells, indicating that SET may play a pathological role for these disorders. SET transcript 2, produced by a specific promoter, represents a major transcript variant in different cell types...

One of the most effective methods to tackle obesity and its related comorbidities is bariatric surgery. Polycystic ovary syndrome (PCOS) and endometrial hyperplasia (EH), which are associated with increased risk of endometrial carcinoma, have been identified as potentially new indications for bariatric surgery. PCOS is the most common endocrine disorder in women in the reproductive age and is associated with several components of the metabolic syndrome such as obesity, insulin resistance and hypertension. EH is a pre-cancerous condition which arises in the presence of chronic exposure to estrogen unopposed by progesterone such as both in PCOS and obesity...

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by the growth of a number of small cysts on the ovaries which leads to sex hormonal imbalance. Women who are affected by this syndrome suffer from irregular menstrual cycles, decline in their fertility, excessive hair growth, obesity, acne and most importantly cardiac function problems. The vascular endothelial growth factor (VEGF) plays a pivotal role in tissue vascularization in general and in the pathogenesis of many diseases...

CONTEXT: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age. Hyperandrogenism is the central feature of PCOS. Studies on isolated ovarian theca-interstitial cells suggest that resveratrol, a natural polyphenol, reduces androgen production. OBJECTIVE: This study was designed to evaluate endocrine and metabolic effects of resveratrol on PCOS. DESIGN AND SETTING: This was a randomized (1:1) double-blind, placebo-controlled trial that evaluated the effects of resveratrol over a period of 3 months in an academic hospital...

Adipokines are cytokines produced mainly by adipose tissue, besides many other tissues such as placenta, ovaries, peripheral-blood mononuclear cells, liver, muscle, kidney, heart, and bone marrow. Adipokines play a significant role in the metabolic syndrome and in cardiovascular diseases, have implications in regulating insulin sensitivity and inflammation, and have significant effects on growth and reproductive function. The objective of this review was to analyze the functions known today of adiponectin, leptin, resistin, and visfatin from placenta throughout childhood and adolescence...

BACKGROUND: It is assumed that obesity adversely affects the health related quality of life (HRQOL) of women with polycystic ovary syndrome (PCOS), not only due to the excess weight, but also due to several other obesity induced metabolic and reproductive consequences. We aimed to compare the effects of excess body weight on the HRQOL between women with PCOS and controls. METHODS: This is a case control study of 142 women with PCOS and 140 age- and BMI- matched controls...

Currently there is growing evidence on possible influence of vitamin D (VD) on reproductive function in both females and males. The relationship between VD and clinical or laboratory manifestations of polycystic ovary syndrome (PCOS) seems to be mostly evaluated. Patients with PCOS have been demonstrated to have significantly lower levels of serum VD and they also have the higher prevalence of vitamin D deficiency as compared to controls. Some studies documented the relation of VD to serum androgen levels, other found that VD correlated with metabolic parameters (body weight, insulin resistance and lipid profile) only...

BACKGROUND: Cervical incompetence is an important cause of miscarriage and premature birth and polycystic ovary syndrome is a heterogeneous endocrine disorder that is the most common cause of anovulatory infertility and eugonadotrophic hypogonadism. By now, it is still debated whether women with PCOS have an increased risk of miscarriage and there have been no studies about the pregnancy outcomes of cervical incompetence patients with PCOS. METHODS: The following clinical data of cervical incompetence patients with/without PCOS who were treated between September 2006 and September 2013 were retrospectively analysed: onset gestational age, termination gestational age, pregnancy outcome, co-morbid insulin resistance (IR) in PCOS patients, the influence of IR, co-morbid hyperandrogenism (HA) in PCOS patients, and the influence of HA...

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common endocrine problem, which is now recognized as not only a reproductive but also a metabolic disorder with long-term effects on women's health, it has a prevalence of 5-10% in India. Among PCOS, it has been reported to have a higher incidence of cardiovascular disorders. Epidemiological studies have demonstrated an association between an increase in the carotid intimo-medial wall thickness (CIMT) and cardiovascular dysfunction. The objective of this study was to compare the CIMT of PCOS with normal women...

Preclinical, early phase clinical trials and epidemiological evidence support the potential role of insulin-sensitizers in cancer prevention and treatment. Insulin-sensitizers improve the metabolic and hormonal profile in PCOS patients and may also act as anticancer agents, especially in cancers associated with hyperinsulinemia and oestrogen dependent cancers. Several lines of evidence support the protection against cancer exerted by dietary inositol, in particular inositol hexaphosphate. Metformin, thiazolidinediones, and myoinositol postreceptor signaling may exhibit direct inhibitory effects on cancer cell growth...

Background. A deficiency of D-chiro-inositol-inositolphosphoglycan mediator (DCI-IPG) may contribute to insulin resistance in polycystic ovary syndrome (PCOS). Whether the relationship between impaired DCI-IPG release and insulin resistance is specific to PCOS rather than obesity is unknown. We assessed insulin-released DCI-IPG and its relationship to insulin sensitivity at baseline and after weight loss in obese women with and without PCOS. Methods. Obese PCOS (n = 16) and normal (n = 15) women underwent 8 weeks of a hypocaloric diet...

AIM: Anti-Müllerian hormone (AMH) levels are two to three times higher in patients with polycystic ovary syndrome (PCOS), but the mechanism of increased AMH levels in PCOS remains unclear. The purpose of our experiment was to investigate a change in AMH levels in two kinds of commonly used rat models and to determine an ideal model for future research of AMH in the pathogenesis of PCOS. METHODS: Thirty female Sprague Dawley rats were treated using two modeling methods: implantation of a levonorgestrel silastic implant or injection with sodium prasterone sulfate plus human chorionic gonadotropin (hCG)...

Studies over the last decade have demonstrated that some polycystic ovary syndrome (PCOS) patients have abnormal insulin sensitivity (insulin resistance), independently from being overweight or obese. This induces the risk of developing type 2 diabetes in such PCOS patients. The use of insulin sensitizers (i.e. metformin), reduces such metabolic, and most hormonal, impairments. As metformin often induces side effects, new integrative strategies have been proposed to treat insulin resistance, such as the use of inositols...

Polycystic ovary syndrome (PCOS) is one of the most commonly occurring metabolic and endocrinological disorders affecting women of reproductive age. Metabolomics is an emerging field that holds promise in understanding disease pathophysiology. Recently, a few metabolomics based studies have been attempted in PCOS patients; however, none of them have included patients from the Indian population. The main objective of this study was to investigate the serum metabolomic profile of Indian women with PCOS and compare them with controls...
