Project description:The granulosa cells in the mammalian ovarian follicle respond to gonadotropin signalling and are involved in the processes of folliculogenesis and oocyte maturation. Studies on gene expression and regulation in human granulosa cells are of interest due to their potential for estimating the oocyte viability and IVF success. The current study determined the mRNA profile by deep sequencing of the two intrafollicular somatic cell types: mural and cumulus granulosa cells isolated from women undergoing controlled ovarian stimulation and in vitro fertilization. Paired cumulus and mural granulosa samples were analysed from 3 women participating in IVF procedure. Differential gene expression study was performed. The identified gene expression profile was also used for predicting targets for miRNAs that were also identified from the same samples (GSE46489).

Project description:Follicular somatic cells (mural granulosa cells and cumulus cells) and the oocyte communicate through paracrine interactions and through direct gap junctions between oocyte and cumulus cells. Considering that mural and cumulus cells arise through a common developmental pathway and that their differentiation is essential to reproductive success, understanding how these cells differ is a key aspect to understanding their critical functions. Changes in global gene expression before and after an ovulatory stimulus were compared between cumulus and mural granulosa cells to test the hypothesis that mural and cumulus cells are highly differentiated at the time of an ovulatory stimulus and further differentiate during the periovulatory interval. The transcriptomes of the two cell types were markedly different (>1500 genes) before an ovulatory hCG bolus but converged after ovulation to become completely overlapping. The predominant transition was for the cumulus cells to become more like mural cells after hCG. This indicates that the differentiated phenotype of the cumulus cell is not stable and irreversibly established but may rather be an ongoing physiological response to the oocyte. We compared transcriptomes of mural granulosa cells isolated from the follicles before (PM-GC) and after (VVM-GC) an ovulatory stimulus. These data were analyzed with previously published cumulus cells data to compare transitions in granulosa cell state before and after an ovulatory stimulus with transitions in cumulus cells.

Project description:Transcriptomes of mouse mural granulosa cells were sequenced to identify transcripts expressed in mural granulosa cells of ovaries. Moreover, transcriptomes of cumulus cells were compared between those of young (2 month-old) and old mice (10 month-old) to assess the effects of ageing on cumulus cells. In addition, transcriptomes of cumulus-oocyte complexes were compared between DBA/2 and (C57BL/6 x DBA/2)F1 mice to assess the strain differences.

Project description:This group consist of human embryologists from the reproductive medical center for of the 1st affiliated hospital of Anhui Medical University. Our research is specifically focused on women ovarian reserve and the relevant female infertility. By deep sequencing, the current experiment determined the small non-coding RNA profile of cumulus cells from patients with or without diminished ovarian reserve undergoing controlled ovarian stimulation and in vitro fertilization treatment. Ovarian follicles, which are a densely-packed shell of granulosa cells that contains an immature or mature oocyte, are above all responsible for the development, maturation, and release of mature egg for fertilization. They are also responsible for synthesizing and secreting hormones that are essential for follicular development, menstrual and estrous cycle, maintenance of the reproductive tracts and their functions, development of female secondary sex characteristics, and metabolism. During folliculogenesis, ovarian granulosa cells surrounding the oocyte differentiate into mural granulosa cells, involved in gonadal steroidogenesis, and into cumulus cells, which are ovulated with the oocyte at ovulation. In the present study, we described the small non-coding RNA expression profile to characterize the ensemble of both known and novel ncRNAs expressed in cumulus cells from patients with or without Diminished ovarian reserve, by using high-throughput Solexa technology.

Project description:The granulosa cells in the mammalian ovarian follicle respond to gonadotropin signalling and are involved in the processes of folliculogenesis and oocyte maturation. Studies on gene expression and regulation in human granulosa cells are of interest due to their potential for estimating the oocyte viability and IVF success. However, the post-transcriptional gene expression studies on miRNA level in the human ovary have been scarce. The current study determined the miRNA profile by deep sequencing of the two intrafollicular somatic cell types: mural and cumulus granulosa cells isolated from women undergoing controlled ovarian stimulation and in vitro fertilization. Paired cumulus and mural granulosa samples were analysed from 3 women participating in IVF procedure. Libraries of all 6 samples were sequenced twice, generating 2 technical replicates for each sample. Differential gene expression study was performed on the pooled results of technical replicates.

Project description:Ovulation requires sequential molecular events and structural remodeling in the ovarian follicle for the successful release of a mature oocyte capable of being fertilised. Critical to this process is progesterone receptor (PGR), a transcription factor highly yet transiently expressed in granulosa cells of preovulatory follicles. Progesterone receptor knockout (PRKO) mice are anovulatory, with a specific and complete defect in follicle rupture. Therefore, this model was used to examine the critical molecular and biochemical mechanisms necessary for successful ovulation. Although PGR is not expressed in the cumulus cells or oocyte of the preovulatory cumulus oocyte complex (COC), it is well known that the COC responds to the cascade of gene expression changes that occurs in preovulatory granulosa cells. We used microarrays to identify putative ‘ovulation’ genes in preovulatory COCs at a time when PGR expression is maximal in granulosa cells (eCG + 8h hCG) and the preovulatory COC and follicle are undergoing the final changes necessary for successful ovulation.
