Project description:The Artemisia iwayomogi (Ai) has been known to inhibit the inflammatory cytokine production and the allergic reactions, and has been used to treat liver diseases. This study investigated the gene expression changes by lipopolysaccharide (LPS) stimulation in the cultured human gingival fibroblast and the gene expression changes by the Ai when challenged with LPS using a microarray chip. Human gingival fibroblast were divided into three experimental groups; â C: Control, â¡ LPS: LPS-treatment only, ⢠LPS-Ai: LPS- and Ai-treatments. Total RNA was isolated from each experimental fibroblast (3 experimental group à 1 sample of each experimental group = total 3 samples).

Project description:The Moutan Cortex Radicis (MCR) has been used as an analgesic, sedative and anti-inflammatory agent. This study investigated the changes in gene expression by MCR treatment when stimulated with lipopolysaccharide (LPS) in cultured human gingival fibroblasts (HGFs) and the gene expression changes by the MCR when challenged with LPS using a microarray chip. Human gingival fibroblast were divided into three experimental groups; 1, C: Control, 2, LPS: LPS-treatment only, 3, MCR40: LPS- and MCR40-treatments. Total RNA was isolated from each experimental fibroblast (3 experimental group M-CM-^W 1 sample of each experimental group = total 3 samples).
Project description:The leaf of Eriobotrya japonica (Ej) has been used for a long time as an oriental medicine to treat pulmonary inflammatory diseases. This study investigated the gene expression changes by lipopolysaccharide (LPS) stimulation in the cultured human gingival fibroblast and the gene expression changes by the leaves of Ej when challenged with LPS using a microarray chip. Human gingival fibroblast were divided into three experimental groups; â C: Control, â¡ LPS: LPS-treatment only, ⢠LPS-Ej: LPS- and Ej-treatments. Total RNA was isolated from each experimental fibroblast (3 experimental group à 1 sample of each experimental group = total 3 samples).
Project description:As part of our study in understanding the role of SP140 in inflammatory pathways in macrophages, we inhibited SP140 mRNA using siRNA. Peripheral blood mononuclear cells (PBMCs) were obtained from whole blood of healthy donors (from Sanquin Institute Amsterdam or from GSK Stevenage Blood Donation Unit) by Ficoll density gradient (Invitrogen). CD14+ monocytes were positively selected from PBMCs using CD14 Microbeads according to the manufacturer’s instructions (Miltenyi Biotec). CD14+ cells were differentiated with 20 ng/mL of macrophage colony-stimulating factor (M-CSF) (R&D systems) for 3 days followed by 3 days of polarization into classically activated (inflammatory) M1 macrophages (100 ng/mL IFN-γ; R&D systems). M1 macrophages were transfected with siGENOME human smartpool SP140 siRNA or non-targeting scrambled siRNA for 48h with DharmaFECT™ transfection reagents according to manufacturer’s protocol (Dharmacon). The cells were left unstimulated or stimulated with 100 ng/mL LPS (E. coli 0111:B4; Sigma) for 4h (for qPCR) or 24h (for Elisa). The cells were lysed (ISOLATE II RNA Lysis Buffer RLY-Bioline) for RNA extraction.150 ng total RNA was labelled using the cRNA labelling kit for Illumina BeadArrays (Ambion) and hybridized with Ref8v3 BeadArrays (Illumina). Arrays were scanned on a BeadArray 500GX scanner and data were normalized using quantile normalization with background subtraction (GenomeStudio software; Illumina).
