This study aimed to determine the microRNA (miRNA) profiles in granulosa cells (GCs) from the follicular fluid (FF) of patients with varying levels of ovarian reserve function. We included 45 women undergoing in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatment. After collecting GCs from each patient, total RNA was extracted from 12 samples. Using Illumina/deep-sequencing technology, we analyzed the small RNAs in each group. Using the R package, we identified the differentially expressed (DE) miRNAs among patients with varying levels of ovarian reserve function...

The evaluation of intra-tumour heterogeneity (ITH) from a transcriptomic point of view is limited. Single-cell cancer studies reveal significant genomic and transcriptomic ITH within a tumour and it is no longer adequate to employ single-subtype assignment as this does not acknowledge the ITH that exists. Molecular assessment of subtype heterogeneity (MASH) was developed to comprehensively report on the composition of all transcriptomic subtypes within a tumour lesion. Using MASH on 3,431 ovarian cancer samples, correlation and association analyses with survival, metastasis, and clinical outcomes were performed to assess the impact of subtype composition as a surrogate for ITH...

Circulating anti-müllerian hormone (AMH) and antral follicle count (AFC) are the best predictors of IVF outcomes. However, in extreme low AMH range especially for young patients, AMH prediction power loose its specificity to give real idea of pregnancy chance with IVF treatments and good prognosis of an extremely reduced ovarian reserve and expected poor response. Indeed, this retrospective study was conducted to evaluate IVF outcomes in patients following IVF-ICSI program with extremely low AMH levels (≤0...

BACKGROUND: Whether non-colorectal non-neuroendocrine liver metastasis (NCNNLM) should be treated surgically remains unclear. METHODS: Data regarding 1,639 hepatectomies performed between 2001 and 2010 for 1,539 patients with NCNNLM were collected from 124 institutions. Patient characteristics, types of primary tumor, characteristics of liver metastases, and post-hepatectomy outcomes were analyzed. RESULTS: The five most frequent primary tumors were gastric carcinoma (540 patients [35%]), gastrointestinal stromal tumor (204 patients [13%]), biliary carcinoma (150 patients [10%]), ovarian cancer (107 patients [7%]), and pancreatic carcinoma (77 patients [5%])...

The pathophysiology of the genuine empty follicle syndrome (EFS) is still debated. Ovarian aging has been contested as a cause of this condition. Our aim was to investigate the occurrence of the genuine EFS in cases of a low number of mature follicles in a prospective manner. Ninety-five infertile women were recruited and evaluated following conventional controlled ovarian stimulation (COS) with ≤ six follicles of ≥14 mm diameter on the day of hCG administration. Enrolled women were 37.5 ± 5...

Most common ovarian cancers are epithelial carcinoma in which the etiology for carcinogenesis remains elusive. ANO1/TMEM16A, a member of Ca2+ -activated Cl- channels (CaCCs), has been demonstrated to promote epithelium-originated cancers and whether it plays a role in the pathogenesis of ovarian cancer is unknown. In our study we found that ANO1 proteins were overexpressed in human epithelial ovarian cancer cells and tissue samples. ANO1 protein upregulation was correlated with the clinical FIGO (International Federation of Gynecology and Obstetrics) staging and poor grade in ovarian cancer tissues...

PURPOSE: The occurrence of diminished ovarian reserve (DOR) in women was growing in recent years. Although in vitro fertilization and embryo transfer (IVF-ET) became an effective treatment for DOR, the live-birth (LB) rate remains unsatisfactory. This study aimed to investigate the impact factors of LB rate in women with DOR undergoing assisted reproduction. METHODS: This was a single-center retrospective cohort study. A total of 2277 IVF-ET or ICSI cycles from 1957 DOR women were analysed...

Endometriosis, a hormone-dependant condition affecting around 10% of women in their reproductive years, has frequent consequences on fertility. Indeed, a proportion of women will require assisted reproductive techniques or surgery in order to achieve pregnancy. Recent refining of stimulation protocols and vitrification techniques has created new possibilities in the field of fertility preservation. As a consequence, oocyte vitrification is now discussed not only in oncologic situations, but also in other conditions at risk of altered ovarian reserve and poor fertility outcome...

Women with impaired ovarian reserve or poor ovarian response (POR) to exogenous gonadotropin stimulation present a challenge for reproductive specialists. The primary reasons relate to the still limited knowledge about the POR pathophysiology and the lack of practical solutions for the management of these conditions. Indeed, clinical trials using the current standards to define POR failed to show evidence in favor of a particular treatment modality. Furthermore, critical factors for reproductive success, such as the age-dependent embryo aneuploidy rates and the intrinsic ovarian resistance to gonadotropin stimulation, are not taken into consideration by the current POR criteria...

The aim of this study is to determine Australians' understanding of the decline in fertility with age, social determinants that influence their decision to start a family and attitudes towards ovarian reserve screening as a tool allowing personalised reproductive life planning. An online survey of 383 childless Australian men and women, aged 18-45 years, was conducted. Both sexes overestimated natural and in vitro fertilization (IVF)-assisted fertility potential with increasing age, with the magnitude of overestimation being more pronounced for men and IVF treatment compared with natural conception...

Women with endometriosis, a benign growth of endometrial tissue outside the uterine cavity, are at increased risk of specific histotypes of epithelial ovarian cancer, such as ovarian endometrioid adenocarcinoma (OEA). Women with OEA who have endometriosis at time of surgical staging demonstrate improved clinical prognosis compared to women with OEA without evidence of endometriosis. However, the molecular contributions of the endometriotic tumor microenvironment to these ovarian cancers remain poorly understood...

Activation of the FOXM1 signaling pathway and the PI3K/AKT/mTOR signaling pathway is associated with poor prognosis in ovarian cancer. In this study, we demonstrated that P15PAF (KIAA0101) was significantly upregulated in high-grade serous ovarian cancer (HGSOC) and that high KIAA0101 expression was associated with poor prognosis. FOXM1 transcriptionally activated KIAA0101 to drive proliferation and metastasis of ovarian cancer cells. KIAA0101 activated the PI3K/AKT/mTOR signaling pathway to inhibit cisplatin-induced apoptosis and autophagy in ovarian cancer cells resulting in cisplatin resistance...
