Gene expression analysis of inositol hexakisphospahte kinase 1 (Ip6k1) knockout testes in juvenile mice

ABSTRACT: Ip6k1 knockout male mice are infertile and display a delay in the first wave of spermatogenesis. To understand the underlying basis of this delay, we compared the gene expression profiles of whole testes from 17 days postpartum (17dpp) and 26 days postpartum (26dpp) Ip6k1 wild type (Ip6k1+/+) and Ip6k1 knockout (Ip6k1-/-) mice. We observed deregulation of several biological processes in Ip6k1-/- testes compared with Ip6k1+/+ testes.

DICER-interacting partners in juvenile mouse testes

Project description:DICER has a well-characterized role in the processing of microRNAs (miRNAs) and small interfering RNAs (siRNA) that are important for post-transcriptional gene regulation. Emerging evidence suggests that DICER also has several non-canonical functions beyond miRNA/siRNA biogenesis, for example in transcriptional gene silencing at the chromatin level, as well as in RNA degradation and maintenance of genomic integrity. We have shown that the function of DICER in germ cells is essential for normal spermatogenesis; male mice lacking DICER in postnatal male germ cells are infertile due to severe defects in haploid differentiation. To better understand the function of DICER in male germ cells, we immunoprecipitated DICER from juvenile mouse testes and performed mass spectrometric analysis to identify DICER-interacting proteins.

Gene expression changes in testes from Abcg8 knockout mice compared to wild-type mice or to Abcg8 knockout mice where plant sterol entry was blocked by ezetimibe

Project description:Abcg8 knockout mice, fed chow, are infertile. These mice also are susceptible to absorption and retention of xenosterols contained in the diet. Ezetimibe, a blocker of dieary sterol entry, can reverse the fertility in Abcg8 knockout mice. In order to identify if the xenosterols resulted in disruption of a specific set of genes in the testes, we compared wild-type testes, Abcg8 knockout testes, or testes from Abcg8 knockout mice fed chow supplemented with 0.005% ezetimibe. To identify genes of interest, we reasoned that any causative gene expression changes seen in Abcg8 knockout mice fed chow, resulting in xenosterol exposure and accumulation, leading to infertilty, would be reveresed back to a pattern seen in the wild-type mice, when Abcg8 knockout mice are raised on chow containing ezetimibe (which prevents xenosterol absorption in the intestine). The target of this drug, Npc1l1, is not expressed in the testes. Testes from wild-type mice, Abcg8 knockout mice, and Abcg8 knockout mice fed chow supplemented with ezetimibe were analyzed.

Gene expression profile in juvenile Spo11 knockout testes

Project description:Spo11, a meiosis-specific protein, introduces double strand breaks on chromosomes and initiates meiotic recombination in a wide variety of organisms. Mouse null Spo11 spermatocytes fail to synapse chromosomes and to progress beyond zygotene stage of meiosis. We analyzed gene expression profiles in Spo11-/- adult and juvenile wild type testis to determine genes expressed in different stages of meiosis and spermatogenesis. These genes were characterized using Gene Ontology. To focus on genes involved in meiosis we performed comparative gene expression analysis of Spo11 -/- and wild type testes from 12 and 15 day mice. We found that the knockout of Spo11 gene causes dramatic changes in the level of expression of genes that participate in meiotic recombination (Hop2, Brca2, Mnd1, FancG) and in the meiotic checkpoint (cyclin B2, Cks2) at 15 day, but does not affect genes encoding protein components of the synaptonemal complex. Finally, we uncovered unknown genes that are affected by disruption of the Spo11gene and therefore, may be specifically involved in meiosis and spermatogenesis. Keywords: repeat sample

Ubb Knockout Mouse Testis

Project description:Analysis of Ubb knockout mouse testes at 7, 4, 21, and 28 dpp. Ubiquitin (Ub) is an essential protein found in all eukaryotic cells and plays important roles in a variety of cellular functions including germ cell development. Targeted disruption of the polyubiquitin gene Ubb results in male and female infertility in mice with germ cells arrested at meiotic prophase I. Whole testes from wild-type (WT) and Ubb−/− (KO) mice were harvested at 7, 14, 21, and 28 days postpartum. Total RNA was extracted and hybridized to Affymetrix Mouse Genome 430 2.0 arrays.

Differential Gene Expression in Cryptorchid Testes

Project description:<p>Differential Gene Expression in Cryptorchid Testes Study uses whole-genome RNA profiling of testicular biopsies to determine a potential causative role of isolated congenital cryptorchidism in azoospermia and/or infertility in the context of our previously published GeneChip data. Cryptorchid patients, aged 7 months to 5 years and otherwise healthy, were enrolled in this prospective study. During surgery, testicular tissue biopsies were obtained for histological examination and RNA-sequencing (RNA-seq). Fifteen patients were selected based on the histological results and were divided into two groups. Seven were classified as belonging to the high infertility risk (HIR) and eight to the low infertility risk (LIR) group. Cryptorchid boys in the high infertility risk group lacked transformation of gonocytes into Ad spermatogonia due to impaired mini puberty. This group of patients will be infertile despite successful surgery.</p>

Drosophila Testis Proteome - Stage-specific testes proteomics of Drosophila melanogaster identifies essential proteins for male fertility

Project description:Spermiogenesis in Drosophila melanogaster is a highly conserved process and essential for male fertility. In this haploid phase of spermatogenesis, motile sperm are assembled from round cells, flagella are assembled, and needle-shaped nuclei with highly compacted genomes are formed. We aimed at identifying proteins relevant for the maturation phase from spermatids to sperm. As transcription takes place mainly in spermatocytes, and transcripts with relevance for post-meiotic sperm development are translationally repressed for days, we comparatively analysed the prote-ome of larval testes (stages before meiotic divisions), of testes of 1–2-day-old pupae (meiotic and early spermatid stages) and adult flies (late spermatids and sperm). We identified 6677 pro-teins, with 422 solely detected in larval testes, 623 in pupal testes and 634 in adult testes. We analysed a few so far uncharacterized proteins with repect to stage specific expression and im-portance for male fertility. For example, Mst84B (gene CG1988), a very basic cysteine- and lysine-rich nuclear protein, was present in the phase of transition from a histone-based to a pro-tamine-based chromatin structure. CG6332 encodes d-Theg, which is related to the mouse tHEG and human THEG proteins. Mutants of d-Theg lacked sperm in the seminal vesicles and were sterile. The identification of numerous predicted proteins underscores the high potential of pro-teome analysis for future analyses of spermatogenesis.

scRNA-Seq of bovine fetal testes derived from NANOS3 knockout and wildtype embryos

Project description:We performed single cell RNA-sequencing (scRNA-Seq) of testes from bovine fetuses derived from either CRISPR/Cas9 NANOS3 knockout (KO; NANOS3 -/-) or wildtype control (NANOS3 +/+) embryos. The scRNA-Seq analysis showed a complete loss of primordial germ cells (PGCs) and gonocytes in NANOS3 KO fetal testes, while maintaining the development of somatic support cells.
