Project description:Applying ChIP-seq with anti-acetylation of lysine 27 on Histone 3 (H3K27Ac), we report high-throughput profiling of H3K27Ac in human skin biopsies taken from psoriasis patients, both from the lesion and from adjacent non-lesion skin, and from skin biopsies from healthy match volunteers, in term of age, gender, and the biopsies place in the body. From each group we had 4 samples. On three samples of each group we performed mRNA array. There is a clearly different H3K27 acetylation patterns in psoriatic skin compared to uninvolved or healthy volunteer skin. in many of the most over express genes in psoriasis lesion, there is enrichment of H3K27Ac. However, loss of acetylation on H3K27 is not part of the biochemical mechanism by which gene expression is decreased in psoriatic skin. Finally, we show Many of the over express genes in psoriasis lesion, that also were enriched with H3K27Ac harbor a putative GRHL transcription factor binding site.

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).

Acne lesion vs. normal skin. Also includes non-acne patients' normal skin samples.

Project description:The pathogenesis of acne has been linked to multiple factors such as increased sebum production, inflammation, follicular hyperkeratinization, and the action of Propionibacterium acnes within the follicle. In an attempt to understand the specific genes involved in inflammatory acne, we performed gene expression profiling in acne patients. Skin biopsies were obtained from an inflammatory papule and from normal skin in six patients with acne. Biopsies were also taken from normal skin of six subjects without acne. Gene array expression profiling was conducted using Affymetrix HG-U133A 2.0 arrays comparing lesional to nonlesional skin in acne patients and comparing nonlesional skin from acne patients to skin from normal subjects. Within the acne patients, 211 genes are upregulated in lesional skin compared to nonlesional skin. A significant proportion of these genes are involved in pathways that regulate inflammation and extracellular matrix remodeling, and they include matrix metalloproteinases 1 and 3, IL-8, human beta-defensin 4, and granzyme B. These data indicate a prominent role of matrix metalloproteinases, inflammatory cytokines, and antimicrobial peptides in acne lesions. These studies are the first describing the comprehensive changes in gene expression in inflammatory acne lesions and are valuable in identifying potential therapeutic targets in inflammatory acne. Keywords: acne lesion, normal skin
