Project description:The current study was designed to investigate the actions of Anti-Müllerian 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 – beta (TGFß) 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-Müllerian Hormone) treated P0 ovary

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. This study is a repetition of a previous study (GEO accession .no.: GSE56737) at the concentration of 50 ng/mL. The overall design are almost similar to GSE56737 except that it was performed in quadruplicate.

The overall design are almost similar to GSE56737 except that it was performed in quadruplicate. 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 one fixed concentration of AMH and an untreated control. The experiments were performed in quadroplicate. In total 16 samples: 2 x conc. (control and 50 ng/ml AMH), 2 x time points, 4 x experiments (quadroplicate). Samples are pairwise comparable within each experiment, that is, sample 1-2 or 3-4 or 5-6 or 7-8 or 9-10 or 11-12 or 13-14 or 15-16. Data are also comparable groupwise; (1,5,9,13) vs (2,6,10,14) or (3,7,11,15) vs (4,8,12,16).

Project description:Fsh-mediated regulation of zebrafish spermatogenesis includes modulating the expression of testicular growth factors. Here, we study if and how two Sertoli cell-derived Fsh-responsive growth factors, anti-Müllerian hormone (Amh; inhibiting steroidogenesis and germ cell differentiation) and insulin-like growth factor 3 (Igf3; stimulating germ cell differentiation), cooperate in regulating spermatogonial development. In dose response and time course experiments with primary testis tissue cultures, Fsh upregulated igf3 transcript levels and down-regulated amh transcript levels; igf3 transcript levels were more rapidly up-regulated and responded to lower Fsh concentrations than were required to decrease amh mRNA levels. Quantification of immunoreactive Amh and Igf3 on testis sections showed that Fsh increased slightly Igf3 staining but decreased clearly Amh staining. Studying the direct interaction of the two growth factors showed that Amh compromised Igf3-stimulated proliferation of type A (both undifferentiated [Aund] and differentiating [Adiff]) spermatogonia. Also the proliferation of those Sertoli cells associated with Aund spermatogonia was reduced by Amh. To gain more insight into how Amh inhibits germ cell development, we examined Amh-induced changes in testicular gene expression by RNA sequencing. The majority (69%) of the differentially expressed genes was down-regulated by Amh, including several stimulators of spermatogenesis, such as igf3 and steroidogenesis-related genes. At the same time, Amh increased the expression of inhibitory signals, such as inha and id3, or facilitated prostaglandin E2 (PGE2) signaling. Evaluating one of the potentially inhibitory signals, we indeed found in tissue culture experiments that PGE2 promoted the accumulation of Aund at the expense of Adiff and B spermatogonia. Our data suggest that an important aspect of Fsh bioactivity in stimulating spermatogenesis is implemented by restricting the different inhibitory effects of Amh and by counterbalancing them with stimulatory signals, such as Igf3

Project description:In order to understand whether sole Cre recombinase expression has an effect on stress signalling pathways and the peroxisomal or other subcellular compartments, we have analyzed total RNA isolated from Sertoli cell cultures of anti-Müllerian-hormone (AMH)-Cre/wild-type and wild-type/wild-type C57BL/6J mouse testes using microarrays. The Sertoli cells were isolated from individual 14 day-old mice and were cultivated for 7 days. Total RNA was isolated from the Sertoli cell culture (for AMH-Cre/WT 5 mice and WT/WT 3 mice) and the same genotypes were pooled together. For the microarray analysis two technical replicates for each genotype were generated.

Project description:The goal of this study was to identify potential AMH-induced genes and regulatory networks controlling regression by RNA-Seq transcriptome analysis of differences in Müllerian Duct mesenchyme between males (AMH signaling on) and females (AMH signaling off) in purified fetal Müllerian Duct mesenchymal cells. This analysis found 82 genes up-regulated in males during MD regression and identified Osterix (Osx)/Sp7, a key transcriptional regulator of osteoblast differentiation and bone formation, as a novel downstream effector of AMH signaling during MD regression.
