Project description:Genome-wide association studies (GWAS) have identified polycystic ovary syndrome (PCOS)-associated loci, including DENND1A encoding a clathrin-binding protein involved in vesicle transport as a guanine nucleotide exchange factor. The effect of DENND1A on reproduction and whether it participates in follicle development disorder and androgen synthesis in PCOS remain unknown. Here, we demonstrated that DENND1A expression increased in ovarian granulosa cells (GCs) of PCOS patients and was positively correlated with serum testosterone concentration. We constructed a systemic transgenic Dennd1a mouse (TG mouse) model, which showed subfertility, irregular estrous cycles, and increased production of testosterone after PMSG stimulation. Moreover, TG mice showed hyporesponsiveness to PMSG with smaller ovary size and less well-developed follicles. Intracellular follicle-stimulating hormone receptor (FSHR) transport was disturbed by overexpression of Dennd1a, which promoted FSHR internalization and inhibited its recycling. Our findings revealed the reproductive function of DENND1A and the underlying mechanisms, which provided new insights into the PCOS pathogenesis and contributing to drug design for PCOS treatment.

Project description:The current study was designed to investigate the actions of Anti-MM-CM-<llerian Hormone (AMH) on primordial follicle assembly. Ovarian primordial follicles develop from the breakdown of oocyte nests during fetal development for the human and immediately after birth in rodents. AMH was found to inhibit primordial follicle assembly, decrease the initial primordial follicle pool size and promote the persistence of small oocyte nests in a rat ovarian organ culture. The AMH expression was found to be primarily in the stromal tissue of the ovaries at this period of development, suggesting a stromal-epithelial cell interaction for primordial follicle assembly. AMH was found to promote alterations in the ovarian transcriptome during primordial follicle assembly with over 200 genes with altered expression. A gene network was identified suggesting a potential central role for the Fgf2/Nudt6 antisense transcript in the follicle assembly process. A number of signal transduction pathways are regulated by AMH actions on the ovarian transcriptome, in particular the transforming growth factor M-bM-^@M-^S beta (TGFM-CM-^_) signaling process. AMH is the first hormone/protein shown to have an inhibitory action on primordial follicle assembly. Due to the critical role of the primordial follicle pool size for female reproduction, elucidation of the factors, such as AMH, that regulate the assembly process will provide insights into potential therapeutics to manipulate the pool size and female reproduction. We used microarrays to determine genes expressed differentially between control and AMH (Anti-MM-CM-<llerian Hormone) treated P0 ovary RNA samples from 3 control groups are compared to 3 AMH treated ovary groups

Project description:In order to identify genes regulated by long noncoding RNA H19 in the ovary, we performed RNA-Seq with WT and H19KO ovaries from 8-week old mice. Among the differentially expressed genes, we found anti-mullerian hormone (AMH), which potentially plays an important role in regulating ovarian follicular development, might be a target of H19 mediated regulation.

Project description:Anti-müllerian hormone (AMH) has an inhibitory effect on ovarian follicle development. However, the mechanism by which AMH regulates folliculogenesis remains to be elucidated. In this study we aimed to investigate the changes in transcriptome of preantral to small antral mice follicles after culturing with AMH and thereby identify candidate genes to be involved.

Project description:The oocytes found within the primordial follicles of mammalian ovaries remain quiescent for months to years until they receive the appropriate signals to undergo the primordial to primary follicle transition and initiate folliculogenesis. The molecular mechanisms and extracellular signaling factors that regulate this process remain to be fully elucidated. The current study investigates the mechanisms utilized by anti-Müllerian hormone (AMH; i.e. Müllerian inhibitory substance) to inhibit the primordial to primary follicle transition. Ovaries from 4-day-old rats were placed into organ culture and incubated in the absence or presence of AMH, either alone or in combination with known stimulators of follicle transition, including basic fibroblast growth factor (bFGF), kit ligand (KITL), or keratinocyte growth factor (KGF). Following 10 days of culture, the ovaries were sectioned, stained, and morphologically evaluated to determine the percentage of primordial versus developing follicles. As previously demonstrated, AMH treatment decreased primordial to primary follicle transition. Interestingly, AMH inhibited the stimulatory actions of KITL, bFGF, and KGF. Therefore, AMH can inhibit the basal and stimulated development of primordial follicles. To investigate the mechanism of AMH actions, the influence AMH has on the ovarian transcriptome was analyzed. AMH treatment when compared with controls was found to alter the expression of 707 genes. The overall effect of AMH exposure is to decrease the expression of stimulatory factors, increase the expression of inhibitory factors, and regulate cellular pathways (e.g. transforming growth factor beta signaling pathway) that result in the inhibition of primordial follicle development. Analysis of the regulatory factors and cellular pathways altered by AMH provides a better understanding of the molecular control of primordial follicle development. Experiment Overall Design: RNA samples from two control groups (pooled untreated cultured ovaries) are compared to two treated groups (pooled cultured ovaries treated with AMH)

In this study we aimed to investigate the changes in transcriptome of preantral to small antral mice follicles after culturing with AMH and thereby identify candidate genes to be involved. Preantral to small antral follicles were collected from dissected ovaries from six to eight weeks old female C57BL/6Tac mice. Twelve hour as well as 24 hour experiments were performed in two different concentrations of AMH. The experiments were performed in triplicate. In total 18 samples: 3 x conc. of AMH, 2 x time points, 3 x experiments (triplicate). Samples are comparable within each experiment, that is, sample 1-3 or 4-6 or 7-9 or 10-12 or 13-15 or 16-18.
