Effects of the sex chromosome complement, XX, XO or XY, on the transcriptome and development of mouse oocytes during follicular growth.

ABSTRACT: 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.

The presence of the Y-chromosome, not the absence of the second X-chromosome, alters the mRNA levels stored in the fully grown XY mouse oocyte

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.

Expression profiles of (40,XX) and (39,XO) females

Project description:Gobal expression analysis in four somatic tissues (brain, liver, kidney and muscle) of adult 40,XX and 39,XO mice with the aim of identifying which genes are expressed from both X chromosomes as well as those genes deregulated in X chromosome monosomy. Keywords: Expression profiling by array For each tissue, the RNA samples of seven 40,XX, eight 39,XpO and eight 39,XmO mice were pooled by genotype into 9 groups, representing 3 biological replicates per genotype, as follows: 39,XpO-1 and 39,XpO-2 (3 pooled individuals each), 39,XpO-3 (2 pooled individuals); 39,XmO-1 and 39,XmO-2 (3 pooled individuals each), 39,XmO-3 (2 pooled individuals); 40,XX-1 and 40,XX-2 (3 pooled individuals each) 40,XX-3 (2 pooled individuals)

Transcriptional consequences of Zfy1 and Zfy2 expression in GV oocytes

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).

Transcription profiling of XX and XY sorted mouse somatic support cells and XX and XY mouse whole gonads to identify potential new mammalian gonadal sex determining genes.

Project description:Gonadal sex determining (GSD) genes that initiate fetal ovarian and testicular development and differentiation are expressed in the cells of the urogenital ridge that differentiate as somatic support cells (SSCs), i.e., granulosa cells of the ovary and Sertoli cells of the testis. To identify potential new mammalian GSD genes, we analyzed the gene expression differences between XX and XY SSCs cells isolated from the gonads of embryonic day (E) 13 mouse fetuses carrying an EGFP reporter transgene expressed specifically in SSCs. In addition, genome wide expression differences between XX and XY E13 whole gonads were examined. Newly identified differentially expressed transcripts are potential GSD genes involved in unexplained human sex reversal cases. Experiment Overall Design: Two seperate RNA samples were obtained from E13 XX and XY sorted EGFP+ cells, and two seperate RNA samples were obtained from E13 XX and XY pooled gonads. Approximately 20ng of total RNA from each sample was used to generate biotin-labelled cDNA. Approximately 2.5ug biotin labelled cDNA of each sample was used for each Mouse Genome 430v2.0 GeneChip array (Affymetrix). Significantly differentially expressed transcripts were identified using R/maanova. Statistical significance was determined at a false discovery rate value of equal to or less than 1%.
