Project description:The porcine ovarian granulosa cells, when analysed during in vitro cultures, may provide new interesting data on the processes associated with in vitro culture of porcine oocytes, as well as assisted reproduction and in vitro fertilisation processes used in the livestock industry. Porcine ovarian granulosa cells were obtained from 43 crossbred Landrace gilts with a median age of 170 days and weight of 98 kg after slaugheter. The cells were harvested after 0h, 48h, 96h and 144h after begining of culture and submited to RNA isolation and microarray analisys. In this study, we demonstrated the gene expression profile of short term primary cultured porcine ovarian granulosa cells.

Project description:The epigenetic transgenerational actions of environmental toxicants and relevant mixtures on ovarian disease was investigated with the use of a fungicide, a pesticide mixture, a plastic mixture, dioxin and a hydrocarbon mixture. After transient exposure of an F0 gestating female rat during embryonic gonadal sex determination, the F1, F2 and F3 generation progeny adult onset ovarian disease was assessed. Transgenerational disease phenotypes observed included an increase in cysts resembling human polycystic ovarian disease (PCO) and a decrease in the ovarian primordial follicle pool size resembling premature ovarian failure (POF). The F3 generation granulosa cells were isolated and found to have a transgenerational effect on the transcriptome and epigenome (differential DNA methylation). Epigenetic biomarkers for environmental exposure and associated gene networks were identified. Epigenetic transgenerational inheritance of ovarian disease states were induced by different classes of environmental compounds suggesting a role of environmental epigenetics in ovarian disease etiology. We used transcriptome microarray analysis to determine genes expressed differentially between F3 control and F3 vinclozolin lineage rat ovary granulosa cell and see which genes might be connected to or cause observed ovary diseases RNA samples from granulosa cell of 3 F3-control lineage groups are compared to granulosa cell of 3 F3-vinclozolin lineage groups

Project description:Cadmium is a heavy metal pollutant and environmental endocrine disruptor. Studies have shown that cadmium exposure, whether it occurs in adulthood, in puberty or during the period from weaning to sexual maturity, can produce notable toxic effects on ovarian cells, especially ovarian granulosa cells. However, the effects of prenatal cadmium exposure on the morphology, function and its epigenetic mechanism of ovarian granulosa cells in offspring during adulthood have not been reported.In this study,the promoter methylation was assessed using MeDIP-Chip and Several methods were used to analyze the scanned genes, including the Gene Ontology Consortium tools, hierarchical clustering and KEGG pathway analysis.The results indicated that multiple signaling pathways, including apoptosis and hormone synthesis related pathways were affected,besides, some genes DNA methylation status of apoptosis and hormone synthesis pathways were changed.In summary, our results provide a scientific basis for subsequent analyses of cadmium-induced ovarian granulosa cell damage and its epigenetic mechanism.

Project description:We investigated the biological effects of ZEA exposure on donkey granulosa cells by using RNA-seq analysis. ZEA at 10 and 30 μM were administered to granulosa cells within 72 hours of in vitro culture. ZEA at 10 μM significantly altered the tumorigenesis associated genes in donkey granulosa cells. Exposure to 10 and 30 μM ZEA treatment significantly reduced mRNA expression of PTEN, TGFβ, ATM, and CDK2 genes, particularly, the ZEA treatment significantly increased the expression of PI3K and AKT genes. Furthermore, immunofluorescence, RT-qPCR, and Western blot analysis verified the gene expression of ZEA-exposed granulosa cells. Collectively, these results demonstrated the deleterious effect of ZEA exposure on the induction of ovarian cancer related genes via the PTEN/PI3K/AKT signaling pathway in donkey granulosa cells in vitro.

Project description:Oxidative stress (OS) is regarded as one of the culprits of ovarian dysfunction. OS causes damage to various types of ovarian cells including granulosa cells (GCs), jeopardizing the ovarian microenvironment, disturbing follicular development and participating in various female reproductive disorder. However, the specific molecular pathological mechanisms underlying this process have not been fully elucidated. Therefore, in this study, human ovarian granulosa cell lines COV434 were treated with 3-nitropropanoic acid, a mitochondrial toxin inducing OS by irreversibly inhibiting the succinate dehydrogenase enzyme in the complex II of electron transport chain, to explore the transcriptome changes upon OS exposure.

Project description:The antral follicle stage plays a crucial role in mammalian oocyte maturation, signifying the final stages of oocyte development and ovulation. This complex process relies on synchronized interactions between oocyte maturation and the proliferation of neighboring granulosa cells. Previous studies have identified two subtypes of granulosa cells in antral follicles: cumulus granulosa cells, located in the inner region, which surround and support the oocyte, and mural granulosa cells, present in the outer layers, which provide mechanical support to the follicular wall and possess steroidogenic functions. Despite the wealth of molecular data generated by these studies, many fundamental questions regarding key developmental events, granulosa cell heterogeneity, functional annotation, and the intricate relationship between somatic cells and oocytes still lack detailed, single-cell resolution-level investigations. In this study, we isolated follicular cells from porcine antral follicles and conducted scRNA-seq to analyze the single-cell transcriptomes of these cells. By identifying and sub-clustering ovarian cells, such as mural granulosa cells and cumulus granulosa cells, we elucidated the heterogeneity of granulosa cells in pigs.

Project description:Single-cell RNA-seq (10x) of the goat ovarian granulosa cells samples from high fertility group (>three babys per birth) and low fertility group (< two babys per birth). The goal of this project is to explore the role of ovarian granulosa cells on the fertility of goat at single cell level. We would like to investigate the role of ovarian granulosa cells on the ovulation rate which indicates fertility. Therefore the ovarian granulosa cells from different population (hihg or low fertility groups animals) were analyzed.
