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.

Description
Fibroblasts from PRDM12 patients and unaffected wildtype relatives were cultured until near confluency. The transcriptional profile of those cells was determined by mRNA sequencing and uncovered differential expression in several known pain and neurodevelopmental genes. Overall design: Transcriptome comparison of human PRDM12 mutant and wildtype fibroblasts
Publication Title
The evolutionarily conserved transcription factor PRDM12 controls sensory neuron development and pain perception.

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.

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
DNA methylation is a dynamic epigenetic modification that plays a key role in various cellular processes. Proteins that bind to DNA depending on its methylation status are thought to play an important role in DNA methylation-mediated gene expression. Using a variety of genomics and proteomics approaches, we identified ZBTB2 as a novel reader of unmethylated DNA. ZBTB2, which forms a complex with ZBTB25 and ZNF639, preferentially binds at CpG island promoters in mouse embryonic stem cells, from where it regulates genes that are involved in the exit from pluripotency. Binding of ZBTB2 to target genes is mostly associated with gene activation. Furthermore, ZBTB2 is intricately interwoven with DNA methylation, as we found not only that its binding to DNA is methylation-sensitive, but also that ZBTB2 regulates the turnover of methylated DNA. Summarising, we propose that ZBTB2 is a DNA methylation-sensitive transcription factor that is involved in cellular differentiation. Overall design: RNA-seq samples of wildtype ESCs and Zbtb2 KO ESCs
Publication Title
ZBTB2 reads unmethylated CpG island promoters and regulates embryonic stem cell differentiation.
