Project description:Sex-reversed ‘XYSry-’ female mice that lack Sry due to the 11 kb deletion Srydl1Rlb have very limited fertility, partly due to the effects of posessing only a single X chromosome. However, the fertility deficit is even worse in sex-reversed XY females than in XO females, implicating Y-linked genes in the further loss of fertility. Transgenic addition of Yp-linked genes to XO females and also to normal XX females implicated Zfy2 (but not the related Zfy1) as the cause of this effect. This study examines the transcriptional effects of Zfy2 and Zfy1 in GV oocytes from normal XX females. 18 samples representing 3 biological replicates from each of 6 genotypes. Genotypes are XX (normal control); XX,Zfy2-nf (control with non-functional Zfy2 transgene); XX,Zfy2 (with Zfy2 transgene); XX,Zfy2+Eif2s3y (contaminated sample, XX with Zfy2 transgene and also an Eif2s3y transgene in proportion of the cells), XX,Zfy1-lo (with single-copy Zfy1 transgene); XX-Zfy1-hi (with multi-copy Zfy1 transgene).

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:The oocytes of B6.Y(TIR) sex-reversed female mouse mature in culture but fail to develop after fertilization because of their cytoplasmic defects. To identify the defective components, we compared the gene expression profiles between the fully-grown oocytes of B6.Y(TIR) (XY) females and those of their XX littermates by cDNA microarray. 173 genes were found to be higher and 485 genes were lower in XY oocytes than in XX oocytes by at least 2-fold. We compared the transcript levels of selected genes by RT-PCR in XY and XX oocytes, as well as in XO oocytes missing paternal X-chromosomes. All genes tested showed comparable transcript levels between XX and XO oocytes, indicating that mRNA accumulation is well adjusted in XO oocytes. By contrast, in addition to Y-encoded genes, many genes showed significantly different transcript levels in XY oocytes. We speculate that the presence of the Y-chromosome, rather than the absence of the second X-chromosome, caused dramatic changes in the gene expression profile in the XY fully-grown oocyte.

We compared the gene expression profiles between the fully-grown oocytes of B6.Y(TIR) (XY) females and those of their XX littermates by cDNA microarray Mouse GV oocytes of B6.Y(TIR) were collected for RNA extraction and hybridization to Affymetrix microarray. We sought to extract the differentially expressed genes in the XY oocytes.

Project description:Purpose: To understand how sex chromosome complement, XX, XO and XY, influences the transcriptome in the oocytes of grwoth phase. Methods: Oocytes of 50 and 60 µm in diameter were isolated from mouse ovaries at 18 dpp and subject to RNA-sequencing. Results: (1) Many X-linked genes are subject to X chromosome dosage dependent expression. (2) Many genes are expressed from both short and long arms of the Y chromosome. (3) The transcriptome landscape in XY oocytes is closer to XX oocytes than XO oocytes. (4) About 10 genes are differentially expressed in XY oocytes compared to XX or XO oocytes. Conclusions: The differences in XY oocytes became exacerbated to differ from XX or XO oocytes near the end of growth phase.

Project description:This repository contains single-nucleus gene expression profiling from mouse livers of the Four Core Genotypes cross. By crossing mice with both a deletion of the sex-determining factor Sry on the Y-chromosome and a transgenic insertion of Sry on Chromosome 3, four combinations of gonadal (testis or ovaries) and chromosomal (XX or XY) are generated, namely XYSry-Chr3Sry+ (gonadal and chromosomal males), XYSry- (gonadal females, chromosomal males), XX (gonadal and chromosomal females), XXChr3Sry+ (gonadal males, chromosomal females). The transgenes are on a C57BL6 genetic background. From all four genotypes, whole livers were dissected and flash frozen, followed by nuclear extraction and fixation for sci-RNA-seq3.

Experiment Overall Design: Whole testes and seminiferous tubules of XX/Sry and W/Wv males were used for microarray expression analysis using the Affymetrix GeneChip system (Affymetrix, CA). In order to isolate the seminiferous tubules, the tunica was carefully removed from the testes which were then incubated in the medium with 5 mg/ml collagnease at 37oC for 40 min. The remaining seminiferous tubules were washed several times with PBS using a 70-ºm cell strainer to remove interstitial cells. After total RNA was extracted using a RNeasy Mini Kit (Qiagen, Germantown, MD), double-stranded cDNA and biotin-labeled cRNA were synthesized using One-Cycle cDNA Synthesis and IVT Labeling kits (Affymetrix, CA), respectively. Twenty micrograms of fragmented biotin-labeled cRNA was hybridized to the Affymetrix Mouse Expression Array MOE 430A for 16 hr at 45oC. The chips were washed, stained, and then scanned with the GeneArray Scanner (Hewlett Packard, CA) in accordance with the manufacturer's standard protocols. Finally, the microarray data were analyzed using Microarray Suite ver. 5.0 (Affymetrix). Differential expression was defined as a difference of 2-fold or more in both whole testis and seminiferous tubule samples between two recipient males. Mouse 430A Affymetrix Genome Array IDs were used to query the NetAffx data mining tool for gene annotations.
