Project description:This gene set contains skin fibroblasts from either labia majora of 46,XY sex reversed females having complete androgen insensitivity syndrome due to inactivation mutations of the androgen receptor gene and from the scrotum of normal males. Both, labia majora and scrotum origin from the same embryological anlagen, the labioscrotal swellings. The phenotypic difference is due to androgen dependent virilization in males. This is not possible in 46,XY patients with complete androgen insensitivity syndrome because the androgen receptor pathway is knocked out. A cell type comparison design experiment design type compares cells of different type for example different cell lines. Cell Line: genital skin fibroblasts from different locations mutant line: normal 46,XY male and 46,XY sex reversed female due to inactivating mutations of the androgen receptor gene Computed

Project description:This dataset contains fibroblasts from different genital and extragenital regions, mostly from 46,XY individuals. Due to proven androgen receptor gene mutations, several individuals have varying degrees of undervirilization of the external genitalia ranging from complete androgen insensitivity syndrome (CAIS) to partial androgen insensitivity syndrome (PAIS). CAIS is a completely female person despite a 46,XY karyotype. AIS-3 individuals have ambigous external genitalia. AIS-4 means predominantly female (clitoral enlargement), AIS-2 means predominantly male (hypospadias). It is important for this experiment set, that it contains data from 3 differet independent datasets that are not directly cmparable with each other. This is because of different reference RNAs and different glass slides. The particular normalization procedure is described in the paper accompanying this dataset. Only then, all arrays are allowed to be clustered together. Dataset 2 and 3 have "DS-2" and "DS-3" in their experiment names. All other experiments belong to dataset 1. A cell type comparison design experiment design type compares cells of different type for example different cell lines. Disease State: normal male, normal female or ambiguous external genitalia according to grading scheme by Sinnecker et al. Cell Line: fibroblast cell lines from different regions of the genital skin, some from extragenital skin Sex/Mating type: 46,XY or 46,XX karyotype Computed

Project description:This SuperSeries is composed of the following subset Series: GSE3871: Effects of androgen treatment on genital fibroblasts GSE3872: Baseline gene transcription in genital fibroblasts 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. Refer to individual Series

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.

Project description:We developed a cellular model to study sex differences in humans. Using somatic cells from a mosaic Kleinefelter patient, we generated isogenic human induced pluripotent stem cell lines with different sex chromosome complements – 47,XXY / 46,XX / 46,XY and 45,X0. 46, XX and 46, XY hiPSCs were differentiated to neural progenitor cells and compared.

Project description:RNA was extracted from adult male and adult female Drosophila melanogaster with reversed sex-chromosome parent-of-origin (e.g. maternal-X/paternal-Y vs. paternal-X/maternal-Y) Parent-of-origin effects were assayed in X/Y males, XY/Y males, and XY/X females. Direct comparisons were made between individuals with the same karyotype (e.g. X/Y males or XY/Y males) incorporating dye-swaps.
