Colon biopsies from Crohns patients and healthy controls
The aim of this study was to investigate differential intestinal gene expression in patients with Crohn's disease (CD) and controls. 172 biopsies from CD and control subjects were studied. Endoscopic biopsies were taken at ileocolonoscopy from five specific anatomical locations including the terminal ileum for RNA extraction.

Combination of peripheral blood gene expression prof...
We used microarrays to identify markers predicting responder status in tocilizumab treatment in rheumatoid arthritis in 13 patients at week 0 and week 4 of treatment.

Comparison of human Rheumatoid arthritis patient per...
Leukocytapheresis((LCAP) is a safe, unique therapy prevalent for intractable rheumatoid arthritis even in case of drug allergy or infectious state. To investigate how to improve LCAP efficacy, we have conducted genes expressions analysis from peripheral blood of Rheumatoid arthritis patients using high resolution DNA microarray just before and after LCAP procedure.

Comparison of mRNA expression in circulating T-cells...
Comparison of mRNA expression showed widespread changes in the circulating CD8+ but not CD4+ T-cells from patients with severe asthma. No changes were observed in the CD4+ and CD8+ T-cells in non-severe asthmatics versus healthy controls. Bioinformatics analysis showed that the changes in CD8+ T-cell mRNA expression were associated with multiple pathways involved in T-cell activation. As with mRNAs, we also observed widespread changes in expression of non-coding RNA species including natural ...

Cytokine treated normal human epidermal keratinocytes
Normal human epidermal keratinocytes (NHEK) from neonatal foreskin were cultured in serum-free EpiLife medium with human KC growth supplement (0.2% bovine pituitary extract (v/v), 5ug bovine insulin, 5ug/ml bovine transferrin, 0.5ng/ml human EGF, and 0.18 ug/ml hydrocortisone) from Cascade Biologics. Cultures were treated with recombinant cytokines from R&D Systems. J Immunol. 2007 Feb 15;178(4):2229-40.

Definition of an ulcerative colitis preinflammatory state
The samples are a part of a study aiming at diagnosing ulcerative colitis from genome-wide gene expression analysis of the colonic mucosa. Colonic mucosal samples were collected as endoscopic pinch biopsies from ulcerative colitis patients and from control subjects. Samples with and without macroscopic signs of inflammation were collected from the patients.

Determinants of excess genetic risk of acute myocard...
Peripheral blood samples of patients with acute myocardial infarction were matched with those of control patients to identify possible differences in corresponding gene expression profiles. The controls were matched to cases based on gender, age, status of diabetes mellitus and smoking status. Six months cardiovascular survival status of the cases was used to identify two distinct subgroups among the cases. Linear models for microarray data (‘limma’) were employed to identify differential gen...
