47, XXX syndrome is one of several sex-chromosomal aneuploidies, and it has an incidence of approximately 1/1000 in newborn females. Because of heterogeneity in X-inactivation, these patients may exhibit a variety of clinical symptoms. Here, we report the generation of an integration-free human induced pluripotent stem cell line (GZHMUi001-A) by using Sendai virus to reprogram peripheral blood mononuclear cells from a 47, XXX syndrome patient with premature ovarian failure. This 47, XXX iPS cell line has characteristics of pluripotent stem cells and is a useful tool for the investigation of this X chromosome aneuploid disease...

Background: Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is an autosomal dominant disease with a low incidence rate. Indel mutations in the forkhead box L2 (FOXL2) gene cause two types of BPES that are distinguished by the presence (type I) or absence (type II) of premature ovarian failure (POF). The purpose of this study was to identify a possible deletion in FOXL2 in Chinese families with BPES and to clarify its relationship with POF. Methods: An autosomal dominant Chinese BPES family with four generations was enrolled in this study...

The primordial follicle assembly, activation and the subsequent development are critical processes for female reproduction. A limited number of primordial follicles are activated to enter the growing follicle pool each wave, and the primordial follicle pool progressively diminishes over a woman's life-time. The number of remaining primordial follicles represents the ovarian reserve. Identification and functional investigation of the factors involved in follicular initial recruitment will be of great significance to the understanding of the female reproduction process and ovarian ageing...

The basic legal conditions for pursuing medical activities in Hungary require that psychologists be employed at certain somatic departments. In the Hungarian medical practice, however, attitudes recognizing the potential role of psychological factors in the course of diseases are not widely present. The modern psychosomatic approach to healing includes biological, psychological and social factors that may predispose one to, precipitate or perpetuate a medical condition. This case study of a 35-year-old woman reports on a therapy in which the symptoms were indicative of both premature ovarian failure and anxiety, influencing each other in a bidirectional way...

Because of the efficacy of systemic therapies, neoplasias which occur in pediatric and adolescent patients and in young adults have high cure rates. This means that fulfilling their wish to have children has become a more pressing concern, particularly among young women with malignant tumors. Premature ovarian failure is also a not insignificant problem as it has a lasting detrimental effect on quality of life. Every oncology patient who may potentially wish to have children should be informed about their options for preserving fertility prior to starting treatment...

The most common forms of hematological malignancies that occur in female reproductive years are lymphoma and leukemia. Areas covered: Several aggressive gonadotoxic regimens such as alkylating chemotherapy and total body irradiation are used frequently in treatment of lymphoma and leukemia leading to subsequent iatrogenic premature ovarian failure and fertility loss. In such cases, female fertility preservation options should be offered in advance. Expert commentary: In order to preserve fertility of young women and girls with lymphoma and leukemia, several established, experimental, and debatable options can be offered before starting chemotherapy and radiotherapy...

Granulosa cells (GCs) play a major role in folliculogenesis and are crucial for oocyte maturation and growth. In these cells, the mTOR/AKT signalling pathway regulates early folliculogenesis by maintaining the dormancy of primordial follicles, while FSH induces their further differentiation and maturation. Because changes in number of CGG triplets in FMR1 exon 1 (below or beyond normal values of 26-34 triplets) affect ovarian reserve and pre-mutations containing >54 CGG triplets represent a known risk factor for premature ovarian insufficiency/failure, we investigated in the human GC model (COV434) how FMR1/FMRP and mTOR/AKT are expressed and potentially interact during GC proliferation...

BACKGROUND: Mammalian folliculogenesis, maturation of the ovarian follicles, require both growth factors derived from oocyte and surrounding cells, including stromal cells. However, the mechanism by which stromal cells and derived factors regulate oocyte development remains unclear. RESULTS: We observed that SENP1, a small ubiquitin-related modifier (SUMO)-specific isopeptidase, was expressed in sm22α-positive stromal cells of mouse ovary. The sm22α-positive stromal cells tightly associated with follicle maturation...

Constant progress in the diagnosis and treatment of cancer disease has increased the number and prognosis of cancer survivors. However, the toxic effects of chemotherapy and radiotherapy on ovarian function have resulted in premature ovarian failure. Patients are, therefore, still expecting methods to be developed to preserve their fertility successfully. Several potential options are available to preserve fertility in patients who face premature ovarian failure, including immature or mature oocyte and embryo cryopreservation...

BACKGROUND: Many reports have shown that various kinds of stem cells have the ability to recover premature ovarian aging (POA) function. Transplantation of human amniotic epithelial cells (hAECs) improves ovarian function damaged by chemotherapy in a mice model. Understanding of how to evaluate the distinct effects of adult stem cells in curing POA and how to choose stem cells in clinical application is lacking. METHODS: To build a different degrees of POA model, mice were administered different doses of cyclophosphamide: light dose (70 mg/kg, 2 weeks), medium dose (70 mg/kg, 1 week; 120 mg/kg, 1 week), and high dose (120 mg/kg, 2 weeks)...

BACKGROUND: Premenopausal women undergoing chemotherapy are at high risk for premature ovarian failure and its long-term consequences. Data on potential markers to evaluate ovarian reserve pre- and posttreatment are limited. Anti-Müllerian hormone (AMH) known for ovarian reserve in reproductive medicine could be a surrogate marker and was assessed in premenopausal breast cancer patients of the SUCCESS A study (EUDRA-CT no. 2005-000490-21). METHODS: We identified 170 premenopausal patients, age ≤ 40 years at trial entry, who received FEC-Doc as taxane-anthracylince based chemotherapy...

Premature ovarian failure (POF) is the term usually used to describe women aged younger than 40 years, who present with amenorrhoea, hypergonadotropic hypogonadism, and infertility. POF is a devastating diagnosis for reproductive-aged women. The clinical presentation is diverse, and several different disorders can lead to premature ovarian failure. POF has serious health consequences, including psychological distress, infertility, osteoporosis, autoimmune disorders, ischaemic heart disease, and increased risk of mortality...

Aleksandra Kruszyńska, Jadwiga Słowińska-Srzednicka
Anti-Müllerian hormone (AMH) in women is secreted by granulosa cells in late preantral and small antral follicles. AMH seems to be a very stable marker having some advantages over other biochemical and biophysical markers and is very useful in the assessment of ovarian reserve. AMH measurement may be used in cases of premature ovarian failure, including iatrogenic, due to treatment for cancer, hypogonadotropic hypogonadism, and lastly, in polycystic ovary syndrome (PCOS). It is also a very specific marker of ovarian tumors - folliculomas...

Forkhead box L2 (FOXL2) is a transcription factor, which is involved in blepharophimosis, ptosis, and epicanthus in versus syndrome (BPES), premature ovarian failure (POF), as well as almost all stages of ovarian development and function. FOXL2 has various target genes, which are implicated in numerous processes, including sex determination, cell cycle regulation and apoptosis and stress response regulation in mammals. However, studies regarding the upstream regulation of FOXL2 are limited. In the present study, the promoter of FOXL2 was successfully cloned and registered in Gen Bank, and a dual luciferase reporter (DLR) analysis demonstrated that the luciferase activity was significantly induced by the promoter of FOXL2...
