Transcriptional consequences of Zfy1 and Zfy2 expression in GV oocytes

ABSTRACT: 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.

Transcriptional consequences of Zfy1 and Zfy2 expression in GV oocytes

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).

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. 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.

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

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.

Caenorhabditis sex-specific RNAseq

Project description:This project defines the transcriptomes of XO (male) and XX (female or mutant pseudo-female) Caenorhabditis nematodes. The data allow the overall composition and sexual regulation of the transcriptome within a single species to be determined. In addition, the five related species studied allow meta-comparisons between them. Because two of the five (C. elegans and C. briggsae) produce a self-fertile XX hermaphrodite, while the XX sex in the remaining three (C. japonica, C. remanei, and C. brenneri) are true females, the data are particularly useful for inferring effects of sexual mode on genome-wide gene expression.

Differential gene expression between feminized C. elegans male and female germlines

Project description:With the aim to determine the extent of germline feminization in feminized male worms, we performed differential gene expression profiling of isolated gonads and whole worms between fog-1(q253) XO males and XX females.

Rapid de novo evolution of X chromosome dosage compensation in Silene latifolia, a plant with young sex chromosomes

Project description:Silene latifolia is a dioecious plant with heteromorphic sex chromosomes that have originated only ~10 MYA and is a promising model organism to study sex chromosome evolution in plants. Previous work suggests that S. latifolia XY chromosomes have gradually stopped recombining and the Y chromosome is undergoing degeneration as in animal sex chromosomes. However, this work has been limited by the paucity of sex-linked genes available. Here, we used 35 Gb of RNA-seq data from multiple males (XY) and females (XX) of a S. latifolia inbred line to detect sex-linked SNPs and identified more than 1700 sex-linked contigs (with X-linked and Y-linked alleles). Analyses using known sex-linked and autosomal genes, together with simulations indicate that these newly identified sex-linked contigs are reliable. Using read numbers, we then estimated expression levels of X-linked and Y-linked alleles in males and found an overall trend of reduced expression of Y-linked alleles, consistent with a widespread ongoing degeneration of the S. latifolia Y chromosome. By comparing expression intensities of X-linked alleles in males and females, we found that X-linked allele expression increases as Y-linked allele expression decreases in males, which makes expression of sex-linked contigs similar in both sexes. This phenomenon is known as dosage compensation and has so far only been observed in evolutionary old animal sex chromosome systems. Our results suggest that dosage compensation has evolved in plants and that it can quickly evolve de novo after the origin of sex chromosomes.
