Transcription profiling of human skin biopsies from individuals with a diagnosis of systemic sclerosis with diffuse scleroderma vs biopsies from normal individiduals

ABSTRACT: We used DNA microarrays to characterize gene expression patterns in skin biopsies from individuals with a diagnosis of systemic sclerosis with diffuse scleroderma and compared those to the patterns of gene expression seen in biopsies from normal, unaffected individuals.

We used DNA microarrays representing >12,000 human genes to characterize gene expression patterns in skin biopsies from individuals with a diagnosis of systemic sclerosis with diffuse scleroderma. We found consistent differences in the patterns of gene expression between skin biopsies from individuals with scleroderma and those from normal, unaffected individuals. The biopsies from affected individuals showed nearly indistinguishable patterns of gene expression in clinically affected and clinica ...[more]

Systemic and cell type-specific gene expression patterns in scleroderma skin

Project description:Abstract: We used DNA microarrays representing >12,000 human genes to characterize gene expression patterns in skin biopsies from individuals with a diagnosis of systemic sclerosis with diffuse scleroderma. We found consistent differences in the patterns of gene expression between skin biopsies from individuals with scleroderma and those from normal, unaffected individuals. The biopsies from affected individuals showed nearly indistinguishable patterns of gene expression in clinically affected and clinically unaffected tissue, even though these were clearly distinguishable from the patterns found in similar tissue from unaffected individuals. Genes characteristically expressed in endothelial cells, B lymphocytes, and fibroblasts showed differential expression between scleroderma and normal biopsies. Analysis of lymphocyte populations in scleroderma skin biopsies by immunohistochemistry suggest the B lymphocyte signature observed on our arrays is from CD20+ B cells. These results provide evidence that scleroderma has systemic manifestations that affect multiple cell types and suggests genes that could be used as potential markers for the disease This SuperSeries is composed of the SubSeries listed below.

Gene Expression Profiling of Scleroderma Skin

Project description:We have analyzed the genome-wide patterns of gene expression with DNA microarrays in skin biopsies from 34 subjects: 17 patients with SSc with diffuse scleroderma (dSSc), 7 patients with SSc with limited scleroderma (lSSc), 3 patients with morphea and 6 healthy controls. In total, 61 skin biopsies were analyzed. The addition of 14 technical replicates resulted in a total of 75 microarray hybridizations. The Intrinsic_scleroderma_genes.txt supplementary file lists the 995 genes with the most consistent expression between each forearm-back pair and technical replicates, but with the highest variance across all samples analyzed. An intrinsic gene identifier algorithm was used to select a set of intrinsic scleroderma genes. A total of 34 experimental groups were defined, each representing the 34 different subjects in our study. Replicate hybridizations for a given patient were assigned to the same experimental group. Each gene was analyzed and assigned a score that is inversely related to how intrinsic the gene's expression is across the samples analyzed. The analysis was repeated on randomized data in order to estimate a False Discovery Rate (FDR). An intrinsic score of 0.3 selected 995 genes with an FDR of 4% (39 Â± 7 genes) while retaining reproducible clustering of technical replicates. Keywords: global gene expression profiling using Agilent Whole Human genome oligo arrays common reference design; we used Universal Human Reference RNA (Stratagene) as our reference for every array; For every hybridization sample RNA was always labeled with Cy3, and reference RNA was always labeled with Cy5; Microarray hybridizations were performed for 61 RNA samples from 34 subjects resulting 61 hybridizations. Fourteen replicate hybridizations were added, resulting in a total of 75 microarray hybridizations.

Transcription profiling of human skin bioposis from patients with diffuse scleroderma and limited scleroderma

Project description:RNA expression profiling was carried out for systemic sclerosis (scleroderma) on skin biopsies obtained from both diffuse scleroderma (dcSSc) and limited scleroderma (lcSSc) subjects patients and compared to normal subjects. The patient group comprised of 4 dcSSc and 2 lcSSc subjects, all of whom were Caucasian and belonged to the age range of 42-73 (Mean age = 61.6). Patient sample set consisted of 3 females and 3 males. Race matched female volunteers from the same geographical area were recruited as controls (n = 4) and belonged to the age range of 41-62 (Mean age = 52).

Scleroderma Morphea Normal Fibroblasts

Project description:Fibroblast were isolated from either back or forearm punch biopsies taken by Dr. Kari Connolly(UCSF) from either normal control patients, patients with a diagnosis of Systemic Sclerosis with Diffuse Scleroderma and patients with a diagnosis of morphea. Scleroderma fibroblast were grown to confluence, media was changed and the RNA prepared from the cells 48 hrs later (to avoid serum responsive genes). A disease state experiment design type is where the state of some disease such as infection, pathology, syndrome, etc is studied. Keywords: disease_state_design

Gene expression in rectal epithelia of cystic fibrosis patients

Project description:Gene expression profiles were recorded from rectal suction specimens of Cystic Fibrosis (CF) patients, carrying the CF-specific D508 mutated CFTR-allele. These profiles were compared with gene expression profiles from rectal suction specimens of non-CF subjects (control). We used Affymetrix GeneChip HG-U133A microarrays to record the gene expression profile of 16 CF and 13 non-CF individuals. Rectal suction specimens representing rectal mucosal epithelia were collected from CF patients and non-CF individuals. Biopsies were analyzed for residual function using ICM and total RNA was isolation immediately using the Qiagen RNeasy protocol with on column DNA digestion. About 1-5 Âµg RNA were obtained from each individual. Integrity of total RNA samples was monitored by gel-electrophoresis before cDNA synthesis. Labeled cRNA synthesis and hybridization was performed following standard protocols.

Human skeletal muscle biopsies from a 3h IL-6 infusion

Project description:Skeletal muscle has been identified as a secretory organ. We hypothesized that IL-6, a cytokine secreted from skeletal muscle during exercise, could induce production of other secreted factors in skeletal muscle. Keywords: Human skeletal muscle time course response to IL-6 infusion IL-6 was infused for 3 h into healthy young males (n=7) and muscle biopsies obtained at time points 0, 3 and 6 h in these individuals. Affymetrix microarray analysis of gene expression profiling in muscle were carried out on 3 randomly chosen subjects.
