(Submitter supplied) Psoriasis is a systemic disease with cutaneous manifestations. MicroRNAs (miRNAs) are non-coding RNA molecules that are differentially expressed in psoriatic skin, however; only few miRNAs have been localized to specific cells or regions of psoriatic lesions. We used laser capture microdissection (LCM) and next-generation sequencing to study the specific miRNA expression profiles in the epidermis (Epi) and dermal inflammatory aggregates (RD/ICs) of psoriatic skin. more...

(Submitter supplied) We report the application of Illumina small RNA sequencing to normal human skin, as well as uninvolved and involved psoriatic skin. By obtaining over 600 million qualified reads from 20 healthy controls and 47 psoriasis biopsies (uninvolved/involved), we have generated a complete small RNA profile in normal and diseased human skin, with particular emphasis on miRNAs. We report the discovery of 284 putative novel miRNAs as well as 98 differentially expressed miRNAs in psoriatic skin.

(Submitter supplied) Background: Psoriasis is a systemic inflammatory skin disease. MicroRNAs (miRNAs) are a class of small non-coding RNA molecules that recently have been found in the blood to be relevant as disease biomarkers. Objective: We aimed to explore miRNAs potential as blood biomarkers for psoriasis. Methods: Using microarray and quantitative real-time PCR we measured the global miRNA expression in whole blood, plasma and peripheral blood mononuclear cells (PBMCs) from patients with psoriasis and healthy controls. more...

(Submitter supplied) In this study, we sought to establish the usefulness of LCM on cDNA microarray analysis. We reported that LCM samples improved the sensitivity of detection of differentially expressed genes over conventional bulk tissue analysis. We also provided the new information of chemokine and its receptor interaction within psoriatic lesional skin.

(Submitter supplied) The efficacy of monoclonal antibodies against either interleukin (IL)-17 or the IL-17 receptor in psoriasis therapy provides strong evidence that IL-17 is the major inflammatory mediation in this disease. However, how IL-17 induces epidermal hyperplasia in psoriasis remains largely unknown. Here, we show that IL-17 actives NF-kB in keratinocytes and initiates the NF-kB-dependent transcription of microRNA-31 (miR-31), one of the most abundant microRNAs in the epidermis of lesional skin of psoriasis and two related mouse models. more...

(Submitter supplied) MicroRNAs (miRNAs) are small non-coding RNAs that have emerged as central regulators of gene expression and powerful biomarkers of disease. Much is yet unknown about their role in psoriasis pathology. To globally characterize the miRNAome of psoriatic skin, skin biopsies were collected from psoriatic cases (n = 75) and non-psoriatic controls (n = 57) and RNA sequenced. Count data was meta-analyzed with a previously published dataset (cases, n = 24, controls, n = 20), increasing the number of psoriatic cases four-fold from previously published studies. more...

(Submitter supplied) MiR-31 is one of the most highly overexpressed miRNAs in psoriasis skin; however, its biological role in the disease has not been studied. Here we show that miR-31 is markedly overexpressed in psoriasis keratinocytes. To study the biological role of miR-31 in keratinocytes, we transfected miR-31 hairpin inhibitor (anti-miR-31) into primary human keratinocytes to inhibit endogenous miR-31. We performed a global transcriptome analysis of keratinocytes upon suppression of endogenous miR-31 using Affymetrix arrays.

(Submitter supplied) Hepatocellular carcinoma (HCC) represents the major histological subtype of liver cancer. Tumorigenic changes in hepatic cells potentially result from aberrant expression of microRNAs (miRNAs). Individual microRNA gene may give rise to miRNAs of different length, named isomiRNAs that proved to be functionally relevant. Results: We detected 374 microRNAs expressed in liver, including miR-122-5p that constituted over 39% ofthe hepatic miRnome. more...

On an Illumina HiSeq 2000 machine, we sequenced 8 miRNA libraries, prepared from small RNA fractions of alveolar macrophages isolated from 8 different healthy animals (Bos taurus). From the data, the potential novel miRNAs were predicted, and the expression levels of the known miRNAs were determined. more...
