Project description:We induced specific deletion of miR-17-92 in Sertoli cells at the time of Amh expression in mouse embryos. We analyzed the effect of this deletion in the long term in adult testis. The transcriptome of mutant testis was consistently altered but do not produce a phenotype due to the testis homeostasis.

Project description:The deletion of a single miRNA cluster, miR-17~92, is sufficient to induce primary sex reversal in XY mice. The expression of the testis determining gene, Sry, is delayed in embryonic XY miR-17~92 knockout gonads, which immediately activate the ovarian genetic program. Single cell RNA-seq analysis shows that Sertoli cell differentiation is highly reduced, delayed and unable to trigger testis differentiation. Consistent with the well-known role of miRNAs in gene regulation, the expression of target genes of miR-17~92 is not stabilized in XY mutant gonads at E11.5, affecting, in turn, the fine regulation of large gene networks involved in mammalian sex determination. Our results reveal that the miR-17~92 cluster is a novel sex-determining factor that modulates several gene networks required for accurate timing of Sry expression and Sertoli cell differentiation during testis determination and early differentiation.

Project description:Adult beta cells in the pancreas are the sole source of insulin in our body. Beta cell loss or increased demand for insulin, impose metabolic challenges because adult beta cells are generally quiescent and infrequently re-enter the cell division cycle. miR-17-92/106b is a family of proto-oncogene microRNAs, that regulate proliferation in normal tissues and in cancer. Here, we employ mouse genetics to demonstrate a critical role for miR-17-92/106b in glucose homeostasis and in controlling insulin secretion. Mass spectrometry analysis was performed on miR-17-92LoxP/LoxP;106-25-/- MEF lysate, without or with CRE-Adenovirus. miR-17-92LoxP/LoxP;106-25+/+ MEFs with GFP-Adenovirus served as controls. We demonstrate that miR-17-92/106b regulate the adult beta cell mitotic checkpoint and that miR-17-92/106b deficiency results in reduction in beta cell mass in-vivo. Furthermore, protein kinase A (PKA) is a new relevant molecular pathway downstream of miR-17-92/106b in control of adult beta cell division and glucose homeostasis. Therefore, contributes to the understanding of proto-oncogene miRNAs in the normal, untransformed endocrine pancreas, and illustrates new genetic means for regulation of beta cell mitosis and function by non-coding RNAs.

Project description:We used two Sertoli-cell-specific Cre lines: Wt1-CreERT2 and Sox9-CreERT2, to induce Sox9 ablation on a Sox8 -/- background in the adult testis. Sox9/8 double KO testes undergo testis-to-ovary genetic reprogramming and Sertoli-to-granulosa cell transdifferentiation.

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.
