Expression data from rat cardiac fibroblasts

ABSTRACT: The overall data contains expression profile of rat genes of cardiac fibroblasts. G-protein signaling is regulated in cardiac fibroblasts. The expresssion of angiotensin II receptor or cytokine such as interleukin is regulated by PTX (which is suggested to suppress Gi function) treatment. Keywords: control or PTX treatment Rat cardiac fibroblasts were primarily isolated and plated onto 6 well plate. Cells were treated with water (Ctl 1-3) or PTX for 24 hr (PTX 1-3) and lysed by Buffer RLT. Total RNA was isolated using QIAGEN kit and gene expression was analysed using Affymetrix Gene Chip system and GCOS analysis.

Pertussis toxin (PTX) is recognized as a specific tool that uncouples receptors from G(i) and G(o) through ADP-ribosylation. During the study analyzing the effects of PTX on Ang II type 1 receptor (AT1R) function in cardiac fibroblasts, we found that PTX increases the number of AT1Rs and enhances AT1R-mediated response. Microarray analysis revealed that PTX increases the induction of interleukin (IL)-1beta among cytokines. Inhibition of IL-1beta suppressed the enhancement of AT1R-mediated respon ...[more]

Project description:To identify a novel target for the treatment of heart failure, we examined gene expression in the failing heart. Among the genes analyzed, 12/15 lipoxygenase (12/15-LOX) was markedly up-regulated in heart failure. To determine whether increased expression of 12/15-LOX causes heart failure, we established transgenic mice that overexpressed 12/15-LOX in cardiomyocytes. Echocardiography showed that 12/15-LOX transgenic mice developed systolic dysfunction. Cardiac fibrosis increased in 12/15-LOX transgenic mice with advancing age, and was associated with the infiltration of macrophages. Consistent with these observations, cardiac expression of monocyte chemoattractant protein-1 (Mcp-1) was up-regulated in 12/15-LOX transgenic mice compared with wild-type mice. Treatment with 12-hydroxy-eicosatetraenotic acid, a major metabolite of 12/15-LOX, increased MCP-1 expression in cardiac fibroblasts and endothelial cells, but not in cardiomyocytes. Inhibition of Mcp-1 reduced the infiltration of macrophages into the myocardium and prevented both systolic dysfunction and cardiac fibrosis in 12/15-LOX transgenic mice. Likewise, disruption of 12/15-LOX significantly reduced cardiac Mcp-1 expression and macrophage infiltration, thereby improving systolic dysfunction induced by chronic pressure overload. Our results suggest that cardiac 12/15-LOX is involved in the development of heart failure and that inhibition of 12/15-LOX could be a novel treatment for this condition. Heart failure is still one of the leading causes of death worldwide. Therefore, it is important to elucidate the underlying mechanisms of heart failure and develop more effective treatments for this condition. To clarify the molecular mechanisms of heart failure, we performed microarray analysis using cardiac tissue samples obtained from a hypertensive heart failure model (Dahl salt-sensitive rats). ~300 genes showed significant changes of expression in the failing hearts compared with control hearts. Among the genes analyzed, 12/15-lipoxygenase (12/15-LOX) was most markedly up-regulated in failing hearts compared with control hearts .

Project description:Epigenetically silenced Ink4a-Arf locus is activated by loss of H3K27me3 in cellular senescence, where secreted factor expression is also involved. Here we analyzed epigenome and transcriptome alteration during Ras-induced senescence using mouse embryonic fibroblast (MEF). Seventeen genes with H3K27me3 loss and H3K4me3 gain showed marked upregulation, including p16Ink4a and Bmp2, a secreted factor for BMP/SMAD signal. Smad6, specific BMP/SMAD pathway inhibitor, was identified as the only one gene showing de novo H3K27 trimethylation with H3K4me3, resulting in strong repression. Ras-activated cells senesced with SMAD1/5/8 phosphorylation, and they escaped from senescence with decreased SMAD1/5/8 phosphorylation when introducing Smad6 or knocking-down Bmp2. Mouse embryonic fibroblasts were established from 13.5 embryonic day embryos of C57/B6. After cells were passaged twice (MEFp2), cells were infected with retroviruses for 48 hours. Then cells were exposed to 4 M-NM-<g/mL peuromycin for selection during days 0-3, and were passed on days 3, 7, and 10. Retroviral vectors for Ras was constructed by cloning cDNAs for wild type HRAS (RasG12) and mutated HRAS (RasV12) by reverse-transcription PCR products from HMEC and SK-BR3 cell RNA, respectively, with N-terminal FLAG tag into pMX vector that contains puromycin resistance gene. Mock pMX vector (mock), and vectors containing RasG12 and oncogenic RasV12 were transfected into plat-E packaging cells using FuGENE 6 Transfection Reagent (Roche, Germany) to prepare retroviruses. Smad6 cDNA with N-termainal 6x Myc tag was also cloned into pMX vector. To knock down Bmp2, double strand oligonucleotide DNA to express small hairpin RNA against Bmp2 (shBmp2) was cloned into RNAi-Ready pSIREN-RetroQ Vector (Clontech, CA). Viral packaging for Smad6 and shBmp2 retrovirus vectors was also done using plat-E cells. For genome-wide transcription analysis, GeneChip Mouse Genome 430 2.0 Array (Affimetrix) was used. For global normalization, the average signal in an array was made equal to 100. Chromatin immunoprecipitation (ChIP)-sequencing was performed. MEFp2 cells and cells with mock, RasG12 or RasV12 infection at day 10 were cross-linked with 1% formaldehyde for 10 min at room temperature and were prepared for ChIP. ChIP using anti-H3K4me3 (ab8580, abcam, rabbit polyclonal) or H3K27me3 (07-142, Upstate, rabbit polyclonal) antibody was performed as described previously. Sample preparation for ChIP-sequencing was performed according to the manufacturer's instructions (Ilumina), and sequencing was performed using Solexa Giga sequencer.

Project description:The cellular ontogeny of hematopoietic stem cells (HSCs) remains poorly understood because their isolation from and their identification in early developing small embryos are difficult. We attempted to dissect early developmental stages of HSCs using an in vitro mouse embryonic stem cell (ESC) differentiation system combined with inducible HOXB4 expression. Here we report the identification of pre-HSCs and an embryonic type of HSCs (embryonic HSCs) as intermediate cells between ESCs and HSCs. Both pre-HSCs and embryonic HSCs were isolated by their c-Kit+CD41+CD45- phenotype. Pre-HSCs did not engraft in irradiated adult mice. After co-culture with OP9 stromal cells and conditional expression of HOXB4, pre-HSCs gave rise to embryonic HSCs capable of engraftment and long-term reconstitution in irradiated adult mice. Blast colony assays revealed that most hemangioblast activity was detected apart from the pre-HSC population, implying the early divergence of pre-HSCs from hemangioblasts. Gene expression profiling suggests that a particular set of transcripts closely associated with adult HSCs is involved in the transition of pre-HSC to embryonic HSCs. Experimental strategy consisted of EB formation, co-culture with OP9 cells, and functional assays. iHOXB4 ESCs were allowed to differentiate spontaneously into EBs for 6 days without HOXB4 expression. We decided to fractionate EB6 cells mainly because by day 6 of culture the number of multipotent progenitors reaches a plateau and several surface markers become detectable. CD41 is known as a marker for the initiation of definitive hematopoiesis. CD41 appeared in a significant proportion of EB cells on day 6 of culture. Induced HOXB4 expression during EB formation did not affect the generation of colony forming cells and repopulating cells in the OP9 and iHOXB4 system or the appearance of surface markers in EB cells. EB6 cells were analyzed and sorted by flow cytometry. Sorted EB6 cells were co-cultured with OP9 cells for various days under HOXB4-on or -off conditions. The minimal requirement of the co-culture period appeared to be only 4 days, which is much shorter than previously thought. After a second analysis and fractionation by flow cytometry, cells were subjected to in vivo repopulating assays under HOXB4-on or -off conditions.
