OBJECTIVE The aim of the present study was to examine whether interactions between polymorphisms in the thyroglobulin and ADAM metallopeptidase with thrombospondin type 1 motif, 16 (ADAMTS16) genes are associated with the development of premature ovarian failure (POF). METHODS A total of 75 patients with POF and 196 controls were involved in this study. We used a GoldenGate assay to genotype ...
Premature ovarian failure (POF) affects approximately 1% of women and is known to be caused by sex chromosome abnormalities, iatrogenic agents and autoimmune diseases, but in the majority of cases the cause is unknown. However, several families have been identified as having an inherited predisposition to POF, suggesting a genetic component to the condition in these cases. The FOXL2 gene of 70 ...
BACKGROUND According to extensive epidemiologic data, infertility is associated with increased ovarian cancer risk. Previous studies showed that both women with infertility and those with ovarian cancer have autoantibodies to ovarian antigens. The objective was to determine if women with infertility have antibodies to mesothelin, a well-characterized ovarian cancer antigen. METHODS Sera were ...
Longer CAG repeat length in the androgen receptor gene is associated with premature ovarian failure.
BACKGROUND Premature ovarian failure (POF) is a disorder characterized by lack of ovulation and elevated serum gonadotrophin levels before the age of 40 years. The cause of POF in most cases is unknown. As mice lacking the Androgen receptor (Ar) gene reportedly have a POF-like phenotype, we hypothesize that, variations in the AR gene maybe one of the causative factors for POF in humans. Thus th...
OBJECTIVE Premature ovarian failure (POF) is a complex, heterogeneous disorder that is influenced by multiple genetic components. This meta-analysis aimed to investigate the association between gene variants and susceptibility to POF. STUDY DESIGN MEDLINE and CNKI were searched for studies published from inception (1950) to June 2014. Meta-analysis was performed when three or more studies rep...
Autoimmunity may be involved in idiopathic premature ovarian failure (POF). However, the frequency, physiopathology and potential reversibility of autoimmune oophoritis needs clarification. Using an ELISA against whole tissue homogenate as antigen, from human ovaries at different ages, positive circulating ovarian antibodies (AOA) were found in 59% of patients with primitive idiopathic POF (27/...
The molecular mechanisms that control reproductive aging and menopausal age in females are poorly understood. Here, we provide genetic evidence that 3-phosphoinositide-dependent protein kinase-1 (PDK1) signaling in oocytes preserves reproductive lifespan by maintaining the survival of ovarian primordial follicles. In mice lacking the PDK1-encoding gene Pdk1 in oocytes, the majority of primordia...
BACKGROUND Spontaneous premature ovarian failure (POF) occurs in 1% of women and has major implications for their fertility and health. Besides X chromosomal aberrations and fragile X premutations, no common genetic risk factor has so far been discovered in POF. Using high-density single nucleotide polymorphism (SNP) arrays, we set out to identify new genetic variants involved in this condition...
OBJECTIVE To examine whether women with premature ovarian failure (POF) have abnormal findings in ocular surface or tear parameters and whether they report symptoms of ocular discomfort compared with age-matched controls. METHODS Sixty-five patients with POF and 36 age-matched healthy controls were examined for signs and symptoms of dry eye. The Ocular Surface Disease Index questionnaire and ...
