Project description:Premature ovarian insufficiency (POI) refers to the severe decline and failure of ovarian function in women before the age of 40, and current treatment methods have significant limitations. In order to screen miRNAs with good anti-apoptotic effect, we used high-throughput sequencing technology to study the differences in exosomal miRNA expression profiles from human follicular fluid between patients with POI and patients with normal ovarian reserve.

Project description:This model is from the article:
Modelling thrombin generation in human ovarian follicular fluid

Abstract:
A mathematical model is constructed to study thrombin production in human ovarian follicular fluid. The model results show that the amount of thrombin that can be produced in ovarian follicular fluid is much lower than that in blood plasma, failing to reach the level required for fibrin formation, and thereby supporting the hypothesis that in follicular fluid thrombin functions to initiate cellular activities via intracellular signalling receptors. It is also concluded that the absence of the amplification pathway to thrombin production in follicular fluid is a major factor in restricting the amount of thrombin that can be produced. Titration of the initial concentrations of the various reactants in the model lead to predictions for the amount of tissue factor and phospholipid that is required to maintain thrombin production in the follicle, as well as to the conclusion that tissue factor pathway inhibitor has little effect on the time that thrombin generation is sustained. Numerical experiments to determine the effect of factor V, which is at a much reduced level in follicular fluid compared to plasma, and thrombomodulin, illustrate the importance for further experimental work to determine values for several parameters that have yet to be reported in the literature.

Project description:Our aim with this work is to identify and quantify the miRNA profile of the human follicular fluid using a miRNA microarray approach in young and advanced-aged women and in follicles with different oocyte quality. Data collected in this study would be utilized in a future as a marker to predict the oocyte quality.

Project description:Follicular fluid (FF) provides a complex and suitable environment for oocyte maturation and contains several molecules secreted from oocyte and granulosa, cumulus, and theca cells. In addition, extracellular vesicles (EV) exist in various body fluids and are known as the cargo of several mRNAs, proteins, and miRNAs to communicate from cell to cell. In this study, we investigated the miRNA profiles of FF-derived EVs.

Project description:Exosomes have recently been shown to play a key role in cell-to-cell communication through delivery of various functional content, including microRNAs (miRNAs). We investigated the potential roles of exosomal miRNA derived intrafollicular cells in polycystic ovary syndrome (PCOS). Using microarray profiling, a total of 492 miRNAs and 220 miRNAs were found in follicular fluid-derived exosomes and serum-derived exosomes, respectively, in PCOS and non-PCOS females. By excluding miRNAs existing in serum-derived exosomes, we found 179 miRNAs which were specifically expressed in follicular fluid-derived exosomes both in PCOS and non-PCOS females.

Project description:Limited research has explored the associations between microRNAs (miRNA) and diminished ovarian reserve (DOR). The study aimed to identify differentially expressed miRNAs in follicular fluid exosomes from women with DOR compared to normal ovarian reserve (NOR) and investigate their role in the proliferation and apoptosis of the human ovarian granulosa tumor cell line KGN.

Project description:Our aim with this work is to identify and quantify the miRNA profile of the human follicular fluid using a miRNA microarray approach in young and advanced-aged women and in follicles with different oocyte quality. Data collected in this study would be utilized in a future as a marker to predict the oocyte quality. This observational prospective study includes women enrolled in the assisted reproduction program of Hospital Universitari i Politècnic la Fe (Valencia, Spain). The study was accepted by IRB of this Hospital and all couples received informed consent of our study and assisted technique according to service protocols. The study was divided in two stages: Stage 1: Patients (n=21) who had follicles yielding oocytes with different degree of maturation were included (n=21). The follicular fluid samples from 21 patients were pooled in different groups. Expression of miRNA in the follicular fluids was compared within each patient according the degree of oocyte maturation. Stage 2: Patients were allocated into two groups according to the patient's age: advanced age (AA; >36 years old) and young age (YA; <36 years old). Follicular fluids from follicles containing MII oocytes were pooled and miRNA expression was subsequently compared. Please note that the MII samples with underscore (such as MII1 vs MII_1) indicate different pools so they are not the same sample, but we maintained the number because they correspond to paired samples pools for GV and MI.
