Project description:Purpose: This study was carried out to determine the consequences of the Rfx2-/- genotype on spermatogenesis in the mouse Methods: RNA was extracted from decapsulated testes of 21 day old mixed background mice of either genotype. Deep sequencing was used to determine quantitative expression of the genomes from independent replicates of each genotype Results: RNA-Seq analysis identified some 105 genes that are down regulated at least 2-fold in Rfx2-/- testes, with ~50 being reduced at least 10-fold Conclusion: Spermatogenesis undergoes complete arrest just prior to the end of the round spermatid period of sperm development in mutant mice. Sequencing results showed that approximately 105 genes were downregulated 2 fold or more in the testes of mutant mice. Comparison of similar studies of targeted mutations in genes for other transcription factor demonstrate that Rfx2 has a large and nearly unique set of genes that depend on it directly or indirectly. A large number of downregulated genes are identified with cilia function. Testicular mRNA profiles were determined by deep sequencing using testes from 5 independent wild type and 6 independent Rfx2-/- mice

Project description:Purpose: This study was carried out to determine the consequences of the Rfx2-/- genotype on spermatogenesis in the mouse Methods: DNA was extracted from decapsulated testes of 21 day old mice. ChIP sequencing was used to determine the binding sites of RFX2. Results: ChIP-Seq analysis identified ~880 binding sites of RFX2 near TSS. Conclusion: Spermatogenesis undergoes complete arrest just prior to the end of the round spermatid period of sperm development in mutant mice. Sequencing results showed that approximately 105 genes were downregulated 2 fold or more in the testes of mutant mice.

Project description:Sry is sufficient to induce testis formation and subsequent male development of internal and external genitalia in chromosomally female mice and humans. In XX sex-reversed males such as XX/Sry-transgenic (XX/Sry) mice, however, testicular germ cells always disappear soon after birth due to germ cell autonomous defects. Therefore, it remains unclear whether or not Sry alone is sufficient to induce a fully functional testicular soma capable of supporting complete spermatogenesis in the XX body. Here we demonstrated that the testicular somatic environment of XX/Sry males is defective in the later phases of spermatogenesis. Spermatogonial transplantation analyses using XX/Sry male mice revealed that donor XY spermatogonia are capable of proliferating, entering meiosis and differentiating into the round spermatid stage. XY donor-derived round spermatids, however, were frequently detached from the XX/Sry seminiferous epithelia and underwent cell death, thereby preventing further progress beyond the elongated spermatid stage. In contrast, immature XY seminiferous tubule segments transplanted under XX/Sry testis capsules clearly displayed proper differentiation into elongated spermatids in the transplanted XY donor tubules. Microarray analysis of seminiferous tubules isolated from XX/Sry testes confirmed missing expression of several Y-linked genes and alterations in the expression profile of genes associated with spermatogenesis. Therefore, our findings indicate dysfunction of the somatic tubule components, probably Sertoli cells, of XX/Sry testes, supporting our hypothesis that Sry alone is insufficient to induce a fully functional Sertoli cell in XX mice.

Project description:We investigated testicular biopsies from 28 men which presented with full spermatogenesis (Johnsen Score 10, 12 samples), arrest at the spermatid stage (Johnsen Score 8, 6 samples), arrest at spermatocyte stage (Johnsen Score 5, 5 samples) and Sertoli-cell-only syndrom (Johnsen Score 2, 5 samples). Testicular biopsies were obtained by the "sandwich" method and conserved in RNALater (Ambion) during surgery. Keywords: spermatogenesis germ cell differentiation Keywords: disease state analysis

Project description:We report the use of the Bulk RNA-sequencing technology on in vivo and in vitro cultured prepubertal testicular tissues. The goal of this study is to identify the origin of the maturation arrest observed in rat prepubertal testicular tissue cultured with the organ culture system with a transcriptomic approach. We compared the gene expression of 14.5 dpp rat testicular tissues cultured up to 6, 16, 22 and 28 days. The statistical filtration revealed 600 differentially expressed genes showing significant differential abundances in all three comparisons. This study uncovered for the first time several mechanisms that could explain the meiotic arrest observed in cultures of rat prepubertal testicular tissues.
