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: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.

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 stimulated T-cell blasts from IL23R R381Q homozygotes (n = 2), healthy controls homozygous for the ancestral allele (n = 9), homozygous individuals for TYK2 P1104A (n = 2) that selectively impairs responses to IL-23, and one patient each with autosomal recessive, complete TYK2 or IL-12Rb1 deficiency with IL-12, IL-23, IL-1b, and IL-1b plus IL-23 for 6 hours and performed RNA-sequencing. We used IL-1b as an IL-23-sensitizing agent as previously reported. We found that while T-cell blasts from IL23R R381Q homozygotes respond normally to IL-12 and IL-1b, their response to IL-23 and to IL-23 plus IL-1b is impaired
Project description:To evaluate the DC genome-wide gene expression in response to beta-glucan and its regulation by IL-1 receptor antagonist (IL-1RA) we used a whole genome microarray. The gene expression profiling was performed in DC left untreated or exposed to beta-glucan for 4 and 12 h, in absence or presence of IL-1RA. This strategy allowed the identification of early/immediate and late/secondary genes regulated by beta-glucan in an IL-1-dependent and -independent manner. Human monocyte-derived DC were obtained by a 6/7-d cultures of freshly isolated monocytes with recombinant human IL-4 (10 ng/ml) and GM-CSF (50 ng/ml). Beta-glucan-associated gene expression and its regulation by IL-1RA in human DC was measured in cells left untreated or at 4 and 12 h after exposure to 10 ug/ml of particulate beta-glucan in absence or presence of 2.5 ug/ml of IL-1RA. Five different conditions (Untreated 0h, beta-glucan 4h, IL-1RA + beta-glucan 4h, beta-glucan 12h, and IL-1RA + beta-glucan 12h) were tested using DC from three different donors.

Project description:Total 23 samples were derived from [1] HUVEC treated in the absence (0h) or presence of hypoxia (1, 2, 4, 8, 12, and 24 hrs) to determine hypoxia-regulated gene in endothelial cells, [2] control siRNA or HIF1α siRNA transfected HUVEC cells treated in the absence or presence of hypoxia, [3] control siRNA or KDM3A siRNA transfected HUVEC cells treated in the absence or presence of hypoxia, [4] ChIP-seq data for HIF1 binding sites and histone modifications under normoxia and hypoxia in endothelial cells.
