ABSTRACT: 9-day-old Sertoli cells have a stronger proliferative activity compared with 21-day-old Sertoli cells. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated and down-regulated genes during this process. Rat Sertoli cell were selected at postnatal day 9 and postnatal day 21 for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the differentially expressed genes that were involved in cell proliferation, cell cycle, and cell death which were associated with the function of Sertoli cell.

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:To compare the the genomic profile of MEFs, immature Sertoli, mature Sertoli cells, and MEFs (NWD) after infection of Nr5a1, Wt1 and Dmrt1 after 1 month of dox exposure. MEFs (NWD) were infected with Nr5a1, Wt1 and Dmrt1 and were exposed to dox for 1 month. MEFs, immature Sertoli and mature Sertoli cells were cultured for 3 days and collected
Project description:The androgen receptor is a steroid receptor belonging to the superfamily of hormone-activated transcriptional factors, displaying distinct expression profiles in Sertoli cells during testis development, tightly correlated to the stages of spermatogenesis.The aim of the project was to better understand the AR signaling pathways, and identify androgen regulated genes in a mature Sertoli cell line (ST38c). In order to identify androgen regulated candidate genes we compared the gene expression of mature Sertoli cells (ST38c) in the absence (condition B) and in the presence of a androgenic ligand, dihydrotestosterone (condition ST). In order to understand the AMH gene repression in mature Sertoli cells, which occurs at puberty, soon after the augmentation of the AR expression, we also compared the gene profile of an immature, not expressing the androgen receptor, prepubertal Sertoli cell line (SMAT1-condition A) with the mature Sertoli cell line (ST38c- condition C), expressing the androgen receptor. The Sertoli cell line SMAT1 has been obtaiend from a 6-day old transgenic male mouse (using the targeted oncogenesis SV40). This cell line has been kindly provided to us by Dr Jean Yves Picard (UMR 782), Universite Paris Sud. (Dutertre M, et al., Mol Cell Endocrinol. 1997 Dec 31;136(1):57-65. PMID 9510068).The Sertoli cell line ST38c was obtained in the INSERM U-693 from 8-wk-old male murine testis; from a transgenic mouse carrying the construct in which the SV40 large T Antigen (TAg) was placed under the control of the human vimentin promoter. The development and description of this new cell line have not yet been published.
Project description:GGPPS was the key enzyme of mevalonate metabolic pathway which was used to synthesize the geranylgeranyl pyrophosphate (GGPP). When we deletion the GGPPS in the sertoli cell and the germ cell loss were found . We used microarrays to detail the global programme of gene expression after GGPPS deletion in sertoli cell and identified 1623 gene expression level change more than 2 times. Primary sertoli cells from 3 days old of control and KO mice for RNA extraction and hybridization on Affymetrix microarrays, every group primare sertoli cell were from more than 30 mice.
Project description:The Wilms tumor gene, Wt1, is specifically expressed in Sertoli cells (SCs) which support spermatogenesis. Germ cell loss was found in Wt1 knockout mice. In vitro studies demonstrated that Wt1 was essential for cell polarity maintenance in SCs. We used Digital Gene Expression Tag Profiling to detail the global programme of gene expression after Wt1 deletion in sertoli cell and identified 710 gene expression level change more than 2 times. Digital Gene Expression Tag Profiling analysis were performed using mRNA from control and Wt1-deficient Primary Sertoli cells, every group primare sertoli cell were from more than 30 mice.
Project description:We examined a regulatory role of the AR during the process of spermatogenesis. Using a SSCs-Sertoli cells co-culture system, we demonstrated that androgen negatively regulated Plzf in SSCs that co-exist with Sertoli cells. In addition, we identified Gata2 as a target of AR in Sertoli cells, and subsequently observed that Wilms tumor 1 (WT1) and β1-integrin as two putative intermediate molecules to transfer the differentiation signals to SSCs. This signal pathway was further verified using androgen pharmacological deprivation mice model. These results demonstrate a regulatory pattern of androgen in SSCs niche, that androgen turns off the stemness maintenance switch PLZF in undifferentiated spermatogonia populations to promote spermatogenesis in an indirect way via multiple steps of signal transduction.
Project description:Environmental toxicants have been shown to induce the epigenetic transgenerational inheritance of adult onset disease, including testis disease and male infertility. The exposure of a gestating female during the period of gonadal sex determination has been shown to promote sperm epimutations, differential DNA methylation regions (DMR), that transmit transgenerational disease to subsequent generations. The current study was designed to determine the impact of an altered sperm epigenome on the subsequent development of an adult somatic cell (Sertoli cell) that influences the onset of a specific disease (male infertility). A gestating female rat (F0 generation) was exposed to the agriculture fungicide vinclozolin during gonadal sex determination and then the subsequent F3 generation progeny used for the isolation of Sertoli cells and assessment of testis disease. As previously observed, a spermatogenic cell apoptosis was observed. The Sertoli cells that provide the physical and nutritional support for the spermatogenic cells were isolated and alterations in gene expression examined. Over 400 genes were differentially expressed in the F3 generation control versus vinclozolin lineage Sertoli cells. A number of specific signaling pathways and cellular processes were identified to be transgenerationally altered. One of the key metabolic processes affected was pyruvate/lactate production that is directly linked to spermatogenic cell viability. The Sertoli cell epigenome was also altered with over 100 promoter differential DNA methylation regions (DMR) modified in the vinclozolin F3 generation Sertoli cell. The genomic features and overlap with the sperm DMR were investigated. Observations demonstrate that the transgenerational sperm epigenetic alterations subsequently alters the development of a specific somatic cell (Sertoli cell) epigenome and transcriptome that then has a role in the adult onset disease (male infertility). The environmentally induced epigenetic transgenerational inheritance of testis disease appears to be a component of the molecular etiology of male infertility.

The F3 generation Sertoli cells have an altered transcriptome and epigenome associated with adult onset testis disease. The environmentally induced epigenetic transgenerational inheritance of Sertoli cell abnormalities appears to be a component of the molecular etiology of male infertility. RNA samples from Sertoli cell of 3 F3-control lineage groups are compared to Sertoli cell of 3 F3-vinclozolin lineage groups
