Effect of BMP-2 on Pulmonary Artery Smooth Muscle Cells from Patients with Idiopathic Pulmonary Arterial Hypertension

Project description:Bone morphogenetic proteins (BMP) inhibit proliferation and induce apoptosis in pulmonary artery smooth muscle cells (PASMC) from normal subjects. Dysfunction of BMP signaling due to mutations in and/or downregulation of BMP receptors has been implicated in idiopathic pulmonary arterial hypertension (IPAH). We examined whether BMP differentially regulates gene expression in PASMC from normal subjects and IPAH patients using the Affymetrix microarray analysis. BMP-2 treatment (200 nM for 24 hrs) altered expression levels of 6,206 genes in normal and IPAH PASMC. 1,063 of these genes were regulated oppositely by BMP-2: 523 genes were downregulated by BMP-2 in normal PASMC but upregulated in IPAH PASMC, whereas 540 genes were upregulated by BMP-2 in normal PASMC but downregulated in IPAH PASMC. The divergent effects of BMP-2 on gene expression profiles indicate that PASMC may undergo significant phenotypic changes in IPAH patients during development of the disease. The transition of the antiproliferative effect of BMP-2 in normal PASMC to its proliferative effect in IPAH patients is attributed potentially to its differential effect on expression patterns of various genes that are involved in cell proliferation and apoptosis. Among the 6206 BMP-2-sensitive genes, there are more than 1800 genes whose expression levels were negatively (with a correlation coefficient, r, < –0.9) or positively (with r > +0.9) correlated with the pulmonary arterial pressure. These results suggest that BMP-mediated gene regulation is significantly altered in PASMC from IPAH patients and mRNA expression changes in BMP-regulated genes may be involved in the development of IPAH.

Reduced FOXF1 Links Unrepaired DNA Damage to Pulmonary Arterial Hypertension

Project description:Pulmonary arterial hypertension (PAH) is a progressive disease in which pulmonary arterial (PA) endothelial cell (EC) dysfunction is associated with unrepaired DNA damage. BMPR2 is the most common mutant gene in PAH. We report that human PAEC with reduced BMPR2 have persistent DNA damage in room air after hypoxic exposure (reoxygenation), as do mice with EC deletion of Bmpr2 (EC-Bmpr2-/-) and persistent pulmonary hypertension. Similar findings are observed in PAEC with loss of the DNA damage sensor ATM, and in mice with Atm deleted in EC (EC-Atm-/-). Gene expression analysis of EC-Atm-/- and EC-Bmpr2-/- lung EC revealed reduced Foxf1, a transcription factor with relative selectivity for lung EC. Reducing FOXF1 in control PAEC induced DNA damage and impaired angiogenesis whereas transfection of FOXF1 in PAH PAEC repaired DNA damage and restored angiogenesis. Lung EC targeted delivery of Foxf1 to reoxygenated EC-Bmpr2-/- mice repaired DNA damage, induced angiogenesis and reversed pulmonary hypertension.

Comparison of gene expression profiles of A549 cell treated with NRF2 siRNA and control siRNA

Project description:To examine the role of NRF2 in accelerating cell proliferation and to identify the target genes responsible for this function, transcriptome analysis was performed using A549 cells, in which NRF2 is constitutively activated. NRF2 was knocked down by siRNA against NRF2, and the gene expression profile was compared with that of A549 cells treated with control siRNA. To exclude off-target effects, three different siRNAs against NRF2 was independently applied. NRF2 siRNA or control siRNA was transfected into A549 cells. Cells were harvested 24 hours after transfection, and total RNA was purified.

Identification of Nrf2-regulated genes in A549 lung cancer cells by oligonucleotide microarray

Project description:To elucidate the mechanisms by which Nrf2 regulates cell growth, we performed global gene expression profiling of A549 lung cancer cells with knockdown of Nrf2. Gene networks associated with carbohydrate metabolism and drug metabolism were significantly downregulated in Nrf2-depleted A549 cells. Gene Set Enrichment Analysis revealed significant enrichment of genes associated with carbohydrate catabolic processes, positive regulation of metabolic processes, PPP, and arachidonic acid metabolism. In summary, this analysis revealed that Nrf2 positively regulates transcription of genes that play key roles in central carbon metabolism. A549 cells were transfected with non targeting NS siRNA or siRNA targeting Nrf2. Mock transfected A549 cells were treated with transfection reagent alone. We had 3 biological replicates for each of the 3 groups. Ninty six hours post transfection, cells were lysed and total RNA was isolated.

Comparison of the transcriptomic impact of NRF2 depletion with that of NUAK1 depletion in SW480 colorectal cancer cells

Project description:The intent of the experiment is to determine how much of NRF2 (NFE2L2)-dependent transcription requires NUAK1 upstream. SW480 cells were transfected with siRNA targeting either NRF2, NUAK1 or non-targeting control, and harvested for analysis by RNA-SEQ 48hrs after transfection. mRNA was analysed by Illumina paired-end RNA-SEQ

Murine pulmonary arterial smooth muscle cells: Wild-type vs. NOX1 deficiency (miRNA profiling)

Project description:NOX1 is a catalytic subunit of nonphagocytic NADPH oxidase, mainly localized to smooth muscle cells in the vasculature. We investigated the pathology underlying the pulmonary arterial hypertension-like phenotype demonstrated in mice deficient in the Nox1 gene (Nox1-KO). Spontaneous enlargement and hypertrophy of the right ventricle, accompanied by hypertrophy of pulmonary vessels, were demonstrated in Nox1-KO at 9-18 weeks of age. Since an increased number of ?-smooth muscle actin-positive vessels was observed in Nox1-KO, pulmonary arterial smooth muscle cells (PASMCs) were isolated and characterized by flow cytometry and TUNEL staining. In Nox1-/Y PASMC, the number of apoptotic cells was significantly reduced without any change in the expression of endothelin-1, and hypoxia-inducible factors HIF-1a and HIF-2a, factors implicated in the pathogenesis of PAH. microRNA expression profiling of mouse pulmonary arterial smooth muscle cells in wild-type and NOX1-KO was analyzed. Pulmonary arterial smooth muscle cells were harvested form 3 mice.

Spontaneous enlargement and hypertrophy of the right ventricle, accompanied by hypertrophy of pulmonary vessels, were demonstrated in Nox1-KO at 9-18 weeks of age. Since an increased number of α-smooth muscle actin-positive vessels was observed in Nox1-KO, pulmonary arterial smooth muscle cells (PASMCs) were isolated and characterized by flow cytometry and TUNEL staining. In Nox1-/Y PASMC, the number of apoptotic cells was significantly reduced without any change in the expression of endothelin-1, and hypoxia-inducible factors HIF-1a and HIF-2a, factors implicated in the pathogenesis of PAH. Transcriptional profiling of mouse pulmonary arterial smooth muscle cells in wild-type and NOX1-KO was analyzed. Pulmonary arterial smooth muscle cells were harvested from 3 mice.
