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:To gain insights into the role of androgen in genital morphogenesis, we compared basal transcriptional patterns in genital fibroblasts from 46,XY individuals with either wild-type AR or germline inactivation of the AR as a result of mutation. A disease state experiment design type is where the state of some disease such as infection, pathology, syndrome, etc is studied. 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: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.

Project description:To decipher hormonal from chromosomal factors we compared DNA-methylation of 27,568 CpG-loci in genital fibroblasts from 46,XY feminized individuals (AIS) with inactivating androgen receptor mutations to those of normal males. The results of the following two subset comparisons are linked to the Series record below: CpG loci differentially methylated (q<0.04) between AIS and male controls (primary human genital fibroblasts): To decipher hormonal from chromosomal factors we compared DNA-methylation of 27,568 CpG-loci in genital fibroblasts from 46,XY feminized individuals (AIS) with inactivating androgen receptor mutations to those of normal males. Cell culture of primary fibroblasts from scrotum/ labia majora from donors with PAIS (n=13), MAIS (n=1) or CAIS (n=13) and 9 controls were analyzed using the HumanMethylation27 Bead Chip. 13 AIS samples and all controls were analyzed in duplicates. Samples with gene call rates <95% as analyzed with BeadStudio software (Illumina, Inc.) and CpGs with detection p-values >0.05 in at least one experiment were excluded from analyses. 54 hybridizations with 25,988 CpGs entered the analysis. Differential methylation analysis (DMA) was performed based on average beta-values were performed using OMICS Explorer (v.2.1(25); Qlucore, Sweden). This file contains CpG loci found differentially methylated (q<0.04) by this approach. CpG loci characterized by a high varibility in their DNA methylation value in AIS compared to male controls (primary human genital fibroblasts): To decipher hormonal from chromosomal factors we compared DNA-methylation of 27,568 CpG-loci in genital fibroblasts from 46,XY feminized individuals (AIS) with inactivating androgen receptor mutations to those of normal males. Cell culture of primary fibroblasts from scrotum/ labia majora from donors with PAIS (n=13), MAIS (n=1) or CAIS (n=13) and 9 controls were analyzed using the HumanMethylation27 Bead Chip. 13 AIS samples and all controls were analyzed in duplicates.

CpG loci with beta-values ranged in control samples up to 0.34 and a difference of the interquartiles between controls and AIS samples above 0.16 were considered as being variably methylated in AIS and are included in this file.
