Project description:We examined the effect of IL-17 signaling pathway on extracellular matrix (ECM) expression and the involvement of IL-17 signaling pathway in pathogenesis of SSc. To identify differences in the expression pattern of ECM genes in IL-17A- or IL-17F-treated cells, we performed PCR array analysis, consisting of 84 ECM-related genes. Normal human dermal fibroblasts were cultured until they were confluent, and then stimulated with IL-17A or IL-17F for 12 hours, and total RNA was extracted. A mixture of equal amounts of mRNAs from three normal fibroblasts was prepared in the presence or absence of IL-17A or -17F, and mRNA expression profile was evaluated using PCR Array.

Normal fibroblasts were obtained by skin biopsies from 3 healthy donors. Fibroblasts from donors were used and treated separately as indicated in the summary. Equal amount total RNA from each donor was pooled prior to gene expression analysis.

Project description:We performed a PCR array of 84 ECM-related genes using RNA obtained from dermal fibroblasts stimulated with or without EBI3. 18 of the 84 genes were upregulated and 22 genes were downregulated in EBI3-treated fibroblasts in comparison with untreated cells. In the present study, we examined the involvement of the IL-12 family cytokines in the expression of the extracellular matrix.

Project description:We performed a PCR array of 84 ECM-related genes using RNA obtained from dermal fibroblasts stimulated presence or absence of IL-12, IL-23 or IL-27. The effects of IL-12, -23 or -27 on COL1A2 mRNA expression were less than 2-fold, as compared with untreated cells.

Project description:TGFβ is one of most intensively studied regulators of extracellular matrix formation, and has been implicated in the development of pulmonary fibrosis in different models. However, little is know about the role of miRNAs in TGFβ mediated fibrogenic gene regulation. By using miRNA qRT-PCR array, we have identified miRNAs whose expression are regulated by TGFβ in IMR-90 cells. Among those down-regulated miRNAs are miR-29 family members. Knockdown miR-29 in IMR-90 cells results in up-regulation of a large number of extracellular matrix and fibrogenic genes including family members of collagen, laminin, integrin, ADAM and MMP, many of them are predicted or confirmed miR-29 targets. Hierarchichal clustering analysis of mRNA array data revealed that many extracellular matrix and fibrogenic genes up-regulated by TGFβ in IMR-90 cells, are also up-regulated in miR-29 KD cells. Moreover, the similar set of extracellular matrix and fibrogenic genes is also significantly up-regulated in bleomycin treated mouse lungs. Together, our data strongly suggest that downstream of the TGFβ, miR-29 is a master modulator of genes involved in extracellular matrix formation and might play a significant role in pulmonary fibrosis.

Project description:Knowledge of differential gene expression between pulp and odontoblasts might give insight to the regulation of these spatially related but functionally diverse cells. Our aim was large-scale analysis of expression profiles of native human pulp tissue and odontoblasts, and search for genes expressed only in odontoblasts. Experiment Overall Design: Microarray using Affymetrix HGU133A (for pulp) and HGU133plus 2.0 array (for odontoblasts) was performed to pooled pulp and odontoblasts of native human third molars. Microarray analysisâ repeatability was estimated by comparing our pulp sample with expression profiles of two pulp samples downloaded from the GEO-database. The genes expressed only in our pulp sample or in odontoblasts were divided into categories, and the expression of selected odontoblast-specific genes of extracellular matrix (ECM) organization and biogenesis category was confirmed with RT-PCR and Western blot.

Project description:CD34+ hematopoietic stem/progenitor cells (HSC) reside in the bone marrow in close vicinity to the endosteal bone surface, surrounded by osteoblasts, stromal cells and various extracellular matrix molecules. We utilized a bioartificial matrix containing fibrillar collagen I, the major matrix component of bone, as scaffold for ex vivo expansion of HSCs. CD34+ HSCs were isolated from umbilical cord blood and cultivated within reconstituted collagen I fibrils in presence of FLT3-ligand, SCF and IL-3. After seven days of culture cell number, colony-forming units and gene expression profile of the cultured cells were assessed. Although the total expansion factor of CD34+ cells was slightly lower when cells were cultivated in the collagen I gel, the frequency of colony-forming units (CFU-C) increased compared to control suspension cultures. Gene expression analysis with microarray chip technology revealed the upregulation of more than 50 genes in presence of collagen I. Among them, genes for several growth factors, cytokines and chemokines (e.g. interleukin 8, MIP1-α) could be confirmed by quantitative PCR. Furthermore, increased expression of the negative cell-cycle regulator BTG2/TIS21 and an inhibitor of MAP kinase pathway, DUSP2, underline the regulatory role of the extracellular matrix. Together, these data show that the expansion of CD34+ cord blood cells in a culture system containing a three-dimensional collagen I matrix induces a qualitative change in the gene expression profile of cultivated HSCs.
