Project description:The aim of the study was to identify differentially expressed genes, isoforms and AS modifications accompanying Gonadal Sex Determination in mice. We performed a Rna-Seq analysis of XX and XY gonads during sex determination on embryonic days 11 (E11) and 12 (E12). RNA-seq libraries were prepared from grouped gonads from E11 and E12 males and females. The cDNA libraries were sequenced using a HiSeq2500 v4 chemistry system

Project description:Abstract: BACKGROUND: Androgen insensitivity syndrome (AIS) comprises a range of phenotypes from male infertility to complete feminization. Most individuals with AIS carry germline mutations of the androgen receptor (AR) that interfere with or ablate its function. As genital fibroblasts retain expression of the AR in vitro, we used genital skin fibroblasts from normal males and 46,XY females with complete AIS due to known AR mutations to gain insights into the role of the AR in human genital differentiation. RESULTS: Using DNA microarrays representing 32,968 different genes, we identified 404 transcripts with significant differences in transcription levels between genital skin fibroblasts cultured from normal and AIS-affected individuals. Gene-cluster analyses uncovered coordinated expression of genes involved in key processes of morphogenesis. On the basis of animal studies and human genetic syndromes, several of these genes are known to have specific roles in genital differentiation. Remarkably, genital fibroblasts from both normal and AIS-affected individuals showed no transcriptional response to dihydrotestosterone treatment despite expression of the AR. CONCLUSIONS: The results suggest that in addition to differences in the anatomic origin of the cells, androgen signaling during prenatal development contributes to setting long-lasting, androgen-independent transcriptional programs in genital fibroblasts. Our findings have broad implications in understanding the establishment and the stability of sexual dimorphism in human genital development.

Project description:Cortical development is a complex process involving the generation of neuronal progenitors, which proliferate and migrate to form the stratified layers of the maturing cortex. To identify microRNAs (miRNAs) and genes that may be important during early cortical development, we analyzed the expression profiles of rat neuronal progenitors obtained at embryonic day 11 (E11), E12 and E13 using microarrays. Neuronal progenitors were purified from telencephalic dissociates with a positive-selection strategy using surface labeling tetanus-toxin and cholera-toxin and fluorescence-activated cell sorting. We identified classes of miRNAs and mRNAs that were up-regulated or down-regulated in these neuronal progenitors as cortical development progressed from E11 to E13. We present data that supports a regulatory role for miRNAs during the transition from neuronal progenitors into differentiating cortical neurons. Experiment Overall Design: Flow cytometry was used to isolate tetanus toxin+ and cholera toxin+ neuronal progenitors from embryonic days 11, 12 and 13 rat telencephalon. 4 biological replicates were obtained for each group using a pooled litters for each biological replicate on different prepararation days

Project description:Single Cell Microarray <br>E10.5 genital ridges (TM at E7.5) incubated in 0.5mM EDTA/ PBS for 20 minutes at 37ï¾°C were transferred to 2% BSA/ PBS. PGCs were collected from the genital ridges pierced with fine glass needles. Released PGCs were identified by their morphological characteristics and transferred into lysis buffer with a mouth pipette. PGCs were genotyped with the remaining genital ridges. The amplified cDNA library of each PGC was classified by qPCR-based expression analyses of Nanog, Oct4, and Stella/Dppa3 (Kurimoto et al., 2007). cDNAs were labeled by in vitro transcription (Affymetrix). The cRNAs were hybridized with the GeneChip Mouse Genome 430 2.0 Array (Affymetrix). Data were analyzed using the Microsoft Excel and MeV (multiple experimental viewer) software. <br>

Project description:We performed genome-wide expression assays comparing gene expression in the Drosophila melanogaster third larval instar genital imaginal disc between males and females. We used microarrays to compare the relative expression levels of five independent male versus female comparisons for each of two different D. melanogaster wild-type strains, Canton-S and Berlin.
