- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
In this study, we investigated if miRNA expression in UC mucosa is altered and correlated our findings with mucosal mRNA expression. Integration of mRNA and miRNA expression profiling may allow the identification of functional links between dysregulated miRNAs and their predicted target mRNA.

Description
Microarrays were used to investigate the the effect of vedolizumab (VDZ) therapy on colonic mucosal gene expression in UC patients and compared the changes to those observed with infliximab (IFX) therapy.
Publication Title

Description
We used microarrays to identify mucosal gene signatures predictive of response to infliximab (IFX) in patients with inflammatory bowel disease (IBD) and to gain more insight into the pathogenesis of IBD.
Publication Title

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The lack of suitable animal models reflecting chronically relapsing inflammation and tissue remodeling have hindered fibrosis research in inflammatory bowel diseases (IBD). This study investigated changes in connective tissue in a chronic murine model using different cycles of dextran sodium sulphate (DSS) to mimic the relapsing nature of the disease.
Publication Title
Unique gene expression and MR T2 relaxometry patterns define chronic murine dextran sodium sulphate colitis as a model for connective tissue changes in human Crohn's disease.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Infliximab, an anti-TNF-alpha monoclonal antibody, is an effective treatment for ulcerative colitis (UC) with over 60% of patients responding to treatment and up to 30% reaching remission. The mechanism of resistance to anti-TNF-alpha is unknown. This study used colonic mucosal gene expression to provide a predictive response signature for infliximab treatment in UC.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Infliximab, an anti-TNFa monoclonal antibody, is an effective treatment for ulcerative colitis (UC) inducing over 60% of patients to respond to treatment. Consequently, about 40% of patients do not respond. This study analyzed mucosal gene expression from patients enrolled in ACT1 to provide a predictive response signature for infliximab treatment.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Increased levels of tissue inhibitor of metalloproteinase-1 (TIMP-1) have been detected in fibrotic strictures in Crohns disease. In a murine model of chronic inflammation, fibrosis was associated with an increase in TIMP-1 and inhibition of matrix metalloproteinase (MMP)-mediated degradation. We investigated the effect of TIMP-1 deficiency on the colonic gene expression in acute and chronic murine models of colitis, using whole genome gene expression arrays.
