Real-time quantitative PCR analysis of 88 microRNAs involved in human cell differentiation and development in involved skin of systemic scleroderma (SSc), localized scleroderma (LSc) and Keloid.

Project description:Skin specimens were derived from involved skin of 3 systemic scleroderma (SSc), 3 localized scleroderma (LSc) and 3 keloid patients. These skin samples and 3 control skins were collected and fixed in formaldehyde immediately after resections. The microRNA (miRNA) isolation from human skin tissue was performed using miRNeasy FFPE kit (Qiagen). For PCR array, miRNAs were reverse-transcribed into first strand cDNA using RT2 miRNA First Strand Kit (SABiosciences). A mixture of equal amounts of miRNAs from 3 normal skins, 3 SSc, 3 LSc or 3 keloid were prepared, and miRNA expression profile in each disease in vivo was evaluated using RT2 Profiler PCR Array. The cDNA was mixed with RT2 SYBR Green/ROX qPCR Master Mix and the mixture was added into 96-well RT2 miRNA PCR Array that includes primer pairs for 88 human miRNAs (SABiosciences). Skin specimens were derived from involved skin of 3 systemic scleroderma (SSc), 3 localized scleroderma (LSc) and 3 keloid patients. These skin samples and 3 control skins were collected and fixed in formaldehyde immediately after resections. Control donors were each matched with diseases for age, sex, and biopsy site.

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 ± 7 genes) while retaining reproducible clustering of technical replicates.

RNA-Seq analysis of skin from bleomycin induced scleroderma murine models treated with EHP-101

Project description:Systemic sclerosis (SSc) or scleroderma is a chronic multiorgan autoimmune disease of unknown etiology characterized by vascular, immunological and fibrotic abnormalities. Several lines of evidence have shown that the endocannabinoid system (ECS) may play a role in the pathophysiology of SSc. VCE-004.8, a CBD aminoquinone derivative, is a dual PPARγ/CB2 that alleviates bleomycin (BLM)-induced skin fibrosis. Herein we report that EHP-101, an oral lipidic formulation of VCE-004.8, prevents skin and lung fibrosis and collagen accumulation in BLM challenged mice. Immunohistochemistry analysis of the skin demonstrate that EHP-101 prevents macrophage infiltration, and the expression of Tenascin C (TNC), VCAM, and the α-smooth muscle actin (SMA). In addition, a reduced expression of vascular CD31, paralleling skin fibrosis, was also prevented by EHP-101. RNAseq analysis in skin biopsies showed a clear effect of EHP-101 in the inflammatory and epithelial-mesenchymal transition transcriptomic signatures. TGF-beta regulated genes such as matrix metalloproteinase-3 (Mmp3), cytochrome b-245 heavy chain (Cybb), lymphocyte antigen 6E (Ly6e), vascular cell adhesion molecule-1 (Vcam1) and the Integrin alpha-5 (Itga5) were induced in BLM mice and repressed by EHP-101 treatment. We also intersected differentially expressed genes in EHP-101-treated mice with dataset of human scleroderma intrinsic genes and found 53 overlapped genes, including the C-C motif chemokine 2 (Ccl2) and the interleukin 13 receptor subunit alpha 1 (IL-13Ra1) genes, which have been studied as biomarkers of SSc. Altogether the results indicate that this synthetic cannabinoid qualifies as a novel compound for the management and possible treatment of scleroderma and, potentially, other fibrotic diseases.

Expression data from murine GVH-SSc skin

Project description:Murine GVH-SSc dorsal scapular skin samples were analyzed to determine the effect of IFNAR-1 inhibition on gene expression at day 14 and day 28. Gene expression in GVH-SSc skin from mice treated with a neutralizing IFNAR-1 antibody was compared to that in GVH-SSc skin from mice treated with isotype IgG, with skin from syngeneic graft controls as reference. For each timepoint, the following samples were analyzed: syngeneic control (n=4); GVH-SSc isotype (n=4); GVH-SSc anti-IFNAR-1 (n=4)
