Expression data from CRS with nasal polyps (CRSwNP) and normal control

ABSTRACT: Chronic rhinosinusitis (CRS) is a prevalent chronic rhinologic disease, characterized by persistent symptomatic inflammation of the nasal mucosa and paranasal sinuses. Sinonasal tissues were obtained during sinus surgeries performed at Northwestern University. For the microarray, NP tissues and uncinate tissues from normal healthy controls were divided into elderly (≥65 years old, each n=3-4), or non-elderly (18-49 years old, each n=3-4) according to age. This study protocol was approved by the independent ethics committees or institutional review boards (IRB) at Northwestern University. Total RNA was isolated from NP tissues and control uncinate tissues. RNA concentration was calculated, and the highest quality RNA used for microarray. The quality of total RNA was evaluated by Bioanalyzer (Agilent Technologies, Santa Clara, CA). The samples were at a concentration ≥125ng/μl and a A260/A280 ratio that was ≥1.80 and a RIN value that was ≥7.0 were considered acceptable. The highest quality RNA was used to generate labeled cRNA and hybridized to Affymetrix Human Gene 2.1ST array following the manufacturer’s protocol (Affymetrix Inc., Santa Clara, CA). Chip processing and image capturing were performed using Affymetrix AGCC software. We investigated age- and disease-related differential gene expression in chronic rhinosinusitis with nasal polyps.

Modulation of microglia-mediated amyloid-beta clearance with nanoformulated polyphenol through the SIRT1-LDLR pathway

Project description:Light-controlled in situ synthesis of DNA microarrays (Affymetrix GeneChip® Mouse Genome 430 2.0) were performed to determine the altered gene expression. Affymetrix algorithm and multiple analysis comparison software were used for assessing gene expression differences, and mRNAs that increased or decreased in the brains of NP(α-M)-treated mice relative to that in the brains of Blank-NP-treated mice were identified. For the assay, total RNA was extracted using Takara RNAiso Plus Kit (Cat#9109, Takara, DaLian, LiaoNing, CN) following the manufacturer’s instructions and checked for a RIN number to inspect RNA integrity by an Agilent Bioanalyzer 2100 (Agilent technologies, Santa Clara, CA, US). Qualified total RNA was further purified by RNeasy mini kit (Cat#74106, QIAGEN, GmBH, Germany) and RNase-Free DNase Set (Cat#79254, QIAGEN, GmBH, Germany). Array hybridization and wash was performed using GeneChip® Hybridization, Wash and Stain Kit (Cat#900720, Affymetrix, Santa Clara, CA, US) in Hybridization Oven 645 (Cat#00-0331-220V, Affymetrix, Santa Clara, CA, US) and Fluidics Station 450 (Cat#00-0079, Affymetrix, Santa Clara, CA, US) followed the manufacturer’s instructions. Slides were scanned by GeneChip® Scanner 3000 (Cat#00-00212, Affymetrix, Santa Clara, CA, US) and Command Console Software 4.0 (Affymetrix, Santa Clara, CA, US) with default settings. Raw data were normalized by MAS 5.0 algorithm, Gene Spring Software12.6.1 (Agilent technologies, Santa Clara, CA, US).

Gene expression analysis of Chronic rhinosinusitis

Project description:Chronic rhinosinusitis (CRS) is a heterogeneous disease characterized by local inflammation of the upper airways which persists for at least 12 weeks. CRS is one of the most common chronic diseases in adults in the United States, affecting over 30 million Americans. CRS is frequently divided into 2 types: CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Histologic studies have demonstrated significant tissue eosinophilia in CRSwNP. T cells in the mucosa are elevated in both forms of CRS and are skewed towards Th2 cytokine expression in CRSwNP. However pathogenic role of CRS has not been fully explored. To screen for pathogenic factors in CRS, we performed a microarray study. We collected uncinate tissues (UT) from 6 subjects with CRSsNP, 6 subjects with CRSwNP and 6 control subjects and nasal polyp (NP) tissues from 6 subjects with CRSwNP and then evaluated gene expression profiles using Affymetrix Human Genome U133 plus 2.0 array. We collected UT from control subjects and pathients with CRSsNP and CRSwNP, and nasal polyp tissues from patients with CRSwNP. Gene expression profiles were evaluated using Human Genome U133 plus 2.0 array (Affymetrix).

Inflammatory molecular endotypes of nasal polyps derived from Caucasian and Japanese populations

Project description:Chronic rhinosinusitis with nasal polyps is a hallmaerk disease in the field of upper airway immunity and chronic inflammation. Diverse inflammatory patterns between nasal polyps have been described in patients that hail from disparate racial and geographic backgrounds. However, it remains unclear whether these immunologic differences in nasal polyps between racial groups are driven by unique molecular mechanisms. We interrogated the gene expression profiles of nasal polyp tissues from Western (United States) and East Asian (Japan) descent, compared to ethmoid sinus tissue controls.

Project description:For the microarray experiments, MV4-11 and MOLM-14 cells were treated with DMSO control, ABT-869 3 nM, SAHA 6 uM and combination therapy for 24 hours. Cells were then washed in PBS and high-quality total RNA was extracted RNeasy Midi Kit, according to the manufacturer’s instruction (Qiagen, Valencia, USA). RNA quantity, quality, and purity were assessed with the use of the RNA 6000 Nano assay on the Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara CA, USA). Gene expression profiling was performed using Affymetric U133plus2.0 gene chip (Affymetrix, Santa Clara, CA, USA) according to the manufacturer’s protocol.

S100A8 Enhances IL-1β Production from Nasal Epithelial Cells in Eosinophilic Chronic Rhinosinusitis

Project description:Chronic rhinosinusitis is classified into eosinophilic chronic rhinosinusitis (ECRS) and non-eosinophilic chronic rhinosinusitis (NECRS). ECRS is a refractory allergic disease involving a variety of immune and epithelial cells. S100A8 is a damage-associated molecular pattern that is closely related to allergic inflammation. However, the pathological implications of S100A8 in ECRS have not been clarified. We evaluated the role of S100A8 in the pathogenesis of ECRS. Gene expression profiles of nasal polyps obtained from patients with ECRS or NECRS were evaluated using RNA sequencing. S100A8 was identified as a significantly upregulated gene in nasal polyps associated with ECRS. Consistently, immunohistochemistry revealed that S100A8 stained intensely in nasal polyps from patients with ECRS. Human nasal epithelial cells expressed the receptor for advanced glycation end products and Toll-like receptor 4. Recombinant S100A8 protein induced interleukin-1β secretion in human nasal epithelial cells. Our data demonstrate that S100A8 induces production of interleukin-1β in the nasal epithelium, which may be involved in the pathogenesis of ECRS.
