Project description:We have employed whole genome microarray expression profiling as a discovery platform to identify the effect of plin1 on gene expression during testis development. Testis of day 21, day 40, and day 60 in plin1-null mice and wild type mice were analyzed. Expression of a list genes (including cyp51, prm1, tnp2) from this signature was quantified in the same RNA samples by real-time PCR, confirming the influence of plin1 on testis development. plin1 knockout alteration gene expression in mice testis was measured at different development phases: day 21 meiosis phase, day 40 puberty phase, and day 60 mature phase. There independent experiments were performed at each time (d21, d40, d60).

Project description:The development of the testis involves a large number of tissue-specific proteins, possibly because that sperms in it are the most divergent of all cell types. Although the proteome of the larval testis of Bombyx mori has been reported, no comprehensive data on adult testis proteome is available for silkworm. In this study, Liquid chromatography-tandem mass spectrometry was employ to investigate the protein compositions of the adult testis of silkworm. A total of 14431 peptides were identified in the adult testis of B. mori, which were match to 2292 proteins. Thirty-two heat shock proteins constitute a group of most abundant proteins in the adult testis, suggested that they are critical for the development, differentiation and survival of germ cells. Other proteins in this analysis were also involved in testis-specific processes mainly including sperm motility, meiosis, germ cell development, and spermatogenesis.

Project description:Todate, the investigation into the molecular mechanisms of testis development and spermatogenesis has largely focused on the role of protein-coding genes and small noncoding RNA including microRNAs and piRNAs. In recent years, long noncoding RNAs (lncRNAs) have been shown to play critical regulatory roles in mammalian development. To understand the role of lncRNAs in development of the mammalian testis and spermatogenesis, we firstly utilized commercial microarray to systematically investigate lncRNAs expression profiles of neonatal (6-day-old) and adult (8-week-old) mouse testis. By comparison the lncRNAs expression profiles of two developmental stage of testes, we obtained the differentially expressed lncRNAs and examined their genomic context, promoter characteristics, neighbored protein-coding genes, provide an important foundation for future research on molecular mechanisms of lncRNAs in mammalian testis development and spermatogenesis.

Project description:Embryonic day 13 (E13), E14, and E16 rat testes and ovaries were used for microarray analysis, as well as E13 testis organ cultures that undergo testis morphogenesis and develop seminiferous cords in vitro. A list of 109 genes resulted from a selective analysis for genes present in male gonadal development and with a 1.5-fold change in expression between E13 and E16. Characterization of these 109 genes potentially important for testis development revealed that cytoskeletal-associated proteins, extracellular matrix factors, and signaling factors were highly represented. Throughout the developmental period (E13-E16), sex-enriched transcripts were more prevalent in the male with 34 of the 109 genes having testis-enriched expression during sex determination. In ovaries, the total number of transcripts with a 1.5-fold change in expression between E13 and E16 was similar to the testis, but none of those genes were both ovary enriched and regulated during the developmental period. Genes conserved in sex determination were identified by comparing changing transcripts in the rat analysis herein, to transcripts altered in previously published mouse studies of gonadal sex determination. A comparison of changing mouse and rat transcripts identified 43 genes with species conservation in sex determination and testis development. Profiles of gene expression during E13-E16 rat testis and ovary development are presented and candidate genes for involvement in sex determination and testis differentiation are identified. Analysis of cellular pathways did not reveal any specific pathways involving multiple candidate genes. However, the genes and gene network identified influence numerous cellular processes with cellular differentiation, proliferation, focal contact, RNA localization, and development being predominant. Experiment Overall Design: RNA samples from two different groups of 20-40 pooled gonads for each sample. Embrionic testis and ovaries of age E13, E14, or E16, and E13 testis cultured for three days were compared to each other

Project description:High dose level dibutyl phthalate (DBP) exposure of fetal rat testes in vivo inhibits testosterone production (i.e. endocrine disruption). Here, fetal testis mRNA levels were profiled following exposure to a DBP dose level that did not significantly reduce testosterone levels. The goal was to identify the constellation of gene expression changes that do not correlate with endocrine disruption. Fischer 344 rats were exposed via oral gavage of the dam to vehicle (corn oil) or 50 mg/kg (body weight) DBP daily from gestational day (GD) 12 to 20. The day after mating was defined as gestational day 0. Six hours after the final exposure on GD20, fetal testes were dissected and mRNA levels quantified using Affymetrix Rat Expression 230 2.0 microarrays.

Project description:We report the application of ChIP-seq targeted at the meiosis-specific protein DMC1 to reveal the genome-wide distribution of initiation of meiotic recombination. The mouse model here employed is Hop2-/- because it is unable to repair the DNA double-stranded breaks and therefore the DMC1 signal is more persistent. We also provide the resulting dataset of ChIP-seq targeted at RAD51 which is not meiosis specific but is also targeted at initiation of recombination loci in meiotic tissue. In addition, we report DMC1 ChIP-seq on wild type mouse pup testis. Finally, we present ChIP-seq targeted at H3K4me3 in testis and liver tissues.
