Transcription profiling of mouse primary dermal fibroblasts treated with endothelin-1

Project description:Mouse primary dermal fibroblasts were treated with 100 nM endothelin-1 (ET1) synthetic peptide for 24 hours. Control samples received no ET1 peptide. The experiment compared treated to untreated to identify gene expression changes due to ET1 exposure. There are three biological replicates for both control and treated samples. These biological replicates represent separate derivations of primary dermal fibroblasts from genetically identical mouse litters aged 0-3 days.

Solar simulated ultraviolet radiation induces histone 3 methylation changes in the gene promoters of matrix metalloproteinases 1 and 3 in primary human dermal fibroblasts [II]

Project description:Skin damage from solar ultraviolet radiation (UVR) accumulates in the dermal extracellular matrix (ECM) and contributes to photoaging. Following UVR exposure, matrix metalloproteinases (MMPs) are secreted by dermal fibroblasts to repair and remodel the ECM. Molecular signaling pathways delineating the induction of MMPs are currently well-defined; however, the effects of UV exposure on epigenetic mechanisms of MMP induction are not as well understood. An epigenetic mechanism would further describe how MMP genes are regulated in response to UV. In this study, we examined solar simulated UVR (ssUVR)-induced gene expression changes and alterations to histone methylation in the promoters of MMP1 and MMP3 in primary human dermal fibroblasts (HDF). This set of gene expression data was generated to identify photoaging related genes (including MMP) that were impacted by ssUVR exposure in our system.

TFF2 miRNA expression in Mus musculus

Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff2 knock-out mouse model, 48 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain.

Changes in gene expression in dermal fibroblasts following exposure to Et1 peptide

Project description:To determine if aberrant activation of endothelin-1 (Et1) could lead to the dysregulation of many downstream genes, we exposed fibroblasts to exogenous ET1 peptide and assayed for transcriptional changes by microarray. Mouse dermal fibroblasts were treated with exogenous Et1 peptide for 24 hours. ET1 treatment resulted in significant expression changes — primarily downregulation — of a number of genes. In particular, Tgfβ2 and Tgfβ3 were among the downregulated genes, which in turn alter the expression status of their many target genes. These data suggest that the stable silencing of Et1 is important for the phenotypic stability of dermal fibroblasts, and perhaps many other cell types as well.
