Project description:A microarray study of sex- and gonad-biased gene expression was conducted to determine whether zebrafish demonstrate male-specific patterns consistent with those observed in other animals. We identified a large number of genes (5899) demonstrating statistical differences in transcript abundance between male and female Danio rerio. All sex-biases in gene expression were due to differences between testis and ovary, although differences between male and female body likely went undetected due to constraints imposed by study design and statistical criteria. Male-enriched genes were more abundant than female-enriched genes, and the magnitude of expression bias for male-enriched genes was greater than that for female-enriched genes. We also identified a large number of candidate reproductive genes based on elevated transcript abundance in testes and ovaries, relative to male body and female body, respectively. Gene expression patterns in adult zebrafish from this study are consistent with the male-biased patterns typical of most animal taxa studied to date. Recent zebrafish studies designed to address more specific questions have not reported the same findings, but major methodological and analytical differences across these studies could explain discrepancies.

Project description:A series of two color gene expression profiles obtained using Agilent 44K expression microarrays was used to examine sex-dependent and growth hormone-dependent differences in gene expression in rat liver. This series is comprised of pools of RNA prepared from untreated male and female rat liver, hypophysectomized (‘Hypox’) male and female rat liver, and from livers of Hypox male rats treated with either a single injection of growth hormone and then killed 30, 60, or 90 min later, or from livers of Hypox male rats treated with two growth hormone injections spaced 3 or 4 hr apart and killed 30 min after the second injection. The pools were paired to generate the following 6 direct microarray comparisons: 1) untreated male liver vs. untreated female liver; 2) Hypox male liver vs. untreated male liver; 3) Hypox female liver vs. untreated female liver; 4) Hypox male liver vs. Hypox female liver; 5) Hypox male liver + 1 growth hormone injection vs. Hypox male liver; and 6) Hypox male liver + 2 growth hormone injections vs. Hypox male liver. A comparison of untreated male liver and untreated female liver liver gene expression profiles showed that of the genes that showed significant expression differences in at least one of the 6 data sets, 25% were sex-specific. Moreover, sex specificity was lost for 88% of the male-specific genes and 94% of the female-specific genes following hypophysectomy. 25-31% of the sex-specific genes whose expression is altered by hypophysectomy responded to short-term growth hormone treatment in hypox male liver. 18-19% of the sex-specific genes whose expression decreased following hypophysectomy were up-regulated after either one or two growth hormone injections. Finally, growth hormone suppressed 24-36% of the sex-specific genes whose expression was up-regulated following hypophysectomy, indicating that growth hormone acts via both positive and negative regulatory mechanisms to establish and maintain the sex specificity of liver gene expression.

Project description:We have used a simple and efficient method to identify condition-specific transcriptional regulatory sites in vivo to help elucidate the molecular basis of sex-differences in transcription, which are widespread in mammalian tissues and affect normal physiology, drug response, inflammation and disease. To systematically uncover transcriptional regulators responsible for these differences, we used DNase hypersensitivity analysis coupled with high-throughput sequencing to produce condition-specific maps of regulatory sites in male and female mouse liver, and for livers of male mice feminized by continuous infusion of growth hormone (GH). We identified 71,264 hypersensitive sites, with 1,284 showing robust sex-differences. Continuous GH infusion suppressed the vast majority of male-specific sites and induced a subset of female-specific sites in male liver. We also identified broad genomic regions (up to ~100kb) showing sex-dependent hypersensitivity and similar patterns of GH response. We found a strong association of sex-specific sites with sex-specific transcription; however, a majority of sex-specific sites were >100kb from sex-specific genes. By analyzing sequence motifs within regulatory regions, we identified two known regulators of liver sexual dimorphism, and several new candidates for further investigation. This approach can readily be applied to mapping condition-specific regulatory sites in mammalian tissues under a wide variety of physiological conditions. Global DNase Hypersensitivity in male, female, and continuous growth hormone-treated male mouse liver tissue. 10 samples: Male liver (2 replicates), Female liver (2 replicates), GH-treated male liver (2 replicates), DNase digested genomic control (from male and female liver separately) and sonicated genomic control (from male and female liver separately).

Project description:The study is relevant to an understanding of the forces that lead to sex differences in the brain. Many neural and psychiatric diseases affect men and women differently, so the understanding of sex differences in brain function impacts on our understanding of why the male and female brain differ in their susceptibility to disease. Using Affymetrix chicken arrays, we will measure the gene expression in male and female embryonic chicken liver to compare with previous studies of brain. Gene expression differs in the male and female embryonic chicken liver. Z-linked genes are expressed higher in males than females, in a manner similar to Z-linked genes in the brain. The comparison of brain and liver will demonstrate which sex differences are specific to brain and which are general. 20 male and 20 female chicken embryos will serve as source of brain tissue. In late stage embryos, we will remove the liver and extract total RNA. Four birds will comprise each individual sample. Thus, we will have 5 biologically independent male samples, and an equal number of female samples. Keywords: dose response

Project description:A series of dual-channel gene expression profiles obtained using Rosetta/Agilent Whole Mouse Genome oligonucleotide microarrays, 4 x 44K format, was used to identify sex-dependent and HNF4alpha-dependent differences in gene expression in adult mouse liver. This series is comprised of four sex-genotype combinations: adult male wild-type liver (M-WT), adult female wild-type liver (F-WT), adult male liver-specific HNF4alpha knockout liver (M-KO) and adult female liver-specific HNF4alpha knockout liver (F-KO). Four pools, each comprised of 4 randomly selected individual liver RNAs, were prepared for each sex-genotype combination. The pools were paired randomly to generate 4 separate experimental comparisons: M-WT:F-WT (first array comparison), M-WT:M-KO (second array comparison), F-WT:F-KO (third array comparison), and M-KO:F-KO (fourth array comparison). A total of 4994 HNF4alpha-dependent genes were identified, of which ~1000 fewer genes responded to the loss of HNF4alpha in female liver as compared to male liver. Moreover, 90% of the genes showing sex-specific expression in the liver were shown to lose sex specificity in HNF4alpha-deficient liver. Keywords: genetic knockout and sex response
