Project description:Objective: Pulmonary complications in systemic sclerosis (SSc), including pulmonary fibrosis (PF) and pulmonary arterial hypertension (PAH), are the leading cause of mortality. We compared the molecular fingerprint of SSc lung tissues and matching primary lung fibroblasts to those of normal donors, and patients with idiopathic pulmonary fibrosis (IPF) and idiopathic pulmonary arterial hypertension (IPAH). Methods: Lung tissues were obtained from 33 patients with SSc who underwent lung transplantation. Tissues and cells from a subgroup of SSc patients with predominantly PF or PAH were compared to those from normal donors, patients with IPF, or IPAH. Microarray data was analyzed using Efficiency Analysis for determination of optimal data processing methods. Real time PCR and immunohistochemistry were used to confirm differential levels of mRNA and protein, respectively. Results: We identified a consensus of 242 and 335 genes that were differentially expressed in lungs and primary fibroblasts, respectively. Enriched function groups in SSc-PF and IPF lungs included fibrosis, insulin-like growth factor signaling and caveolin-mediated endocytosis. Functional groups shared by SSc-PAH and IPAH lungs included antigen presentation, chemokine activity, and IL-17 signaling. Conclusion: Using microarray analysis on carefully phenotyped SSc and comparator lung tissues, we demonstrated distinct molecular profiles in tissues and fibroblasts of patients with SSc-associated lung disease compared to idiopathic forms of lung disease. Unique molecular signatures were generated that are disease- (SSc) and phenotype- (PF vs PAH) specific. These signatures provide new insights into pathogenesis and potential therapeutic targets for SSc lung disease.

Project description:These microarray studies were performed using whole lungs of BALB/C mice during development of hypoxia-induced pulmonary hypertension (days 1-21) and resolution of pulmonary hypertension after return to normoxia (days 22-35) . Mice were sampled during nine time-points and each time-point was replicated 4 times (with dye swapping). Keywords = hypoxia Keywords = pulmonary hypertension

Project description:Rationale: Pulmonary arterial hypertension is a common and potentially fatal complication of scleroderma that may involve inflammatory and autoimmune mechanisms. Alterations in the gene expression of peripheral blood mononuclear cells have been previously described in patients with pulmonary arterial hypertension. The ability to identify patients at risk for developing pulmonary hypertension would be clinically beneficial. Objective: To identify genes that are differentially expressed in peripheral blood mononuclear cells in scleroderma patients with and without pulmonary hypertension which could be used as biomarkers of disease for early diagnosis and provide insight into pathogenesis of pulmonary hypertension in at-risk populations. Methods and Results: Gene expression analysis was performed on a carefully characterized Microarray Cohort of scleroderma patients with (n=10) and without (n=10) pulmonary hypertension. Differentially expressed genes were confirmed in the Microarray Cohort and validated in a separate Validation Cohort of scleroderma patients with (n=15) and without (n=19) pulmonary hypertension by RT-qPCR. We identified inflammatory and immune-related genes including interleukin-7 receptor (IL-7R) and chemokine receptor 7 (CCR7) as differentially expressed in patients with scleroderma-associated pulmonary hypertension. Flow cytometry confirmed decreased expression of IL-7R on circulating CD4+ T cells from scleroderma patients with pulmonary hypertension. Conclusions: Differences exist in the expression of inflammatory and immune-related genes in peripheral blood cells derived from patients with scleroderma-related pulmonary hypertension compared to those with normal pulmonary artery pressures. These findings may have implications as biomarkers to screen at-risk populations to facilitate early diagnosis and provide insight into inflammatory and autoimmune mechanisms of scleroderma-related pulmonary hypertension. Gene expression analysis was performed on a carefully characterized Microarray Cohort of scleroderma patients with (n=10) and without (n=10) pulmonary hypertension. Differentially expressed genes were confirmed in the Microarray Cohort by RT-qPCR.

Project description:Combined pulmonary fibrosis and emphysema (CPFE) is characterized by upper-lobe emphysema combined with lower-lobe fibrosis and a high prevalence of pulmonary hypertension. The aim of this study was to measure and analyze gene expression profiles in the lungs of CPFE patients. The results showed that the expression profiles of the fibrotic and emphysematous lesions were remarkably different in terms of function. Genes related to immune system, structural constituents of cytoskeleton, and cellular adhesion were overexpressed in fibrotic lesions, while genes associated with cellular fraction, cell membrane structures, vascular growth and biology, second-messenger-mediated signaling, and lung development (all processes that contribute to the destruction and repair of cells, vessels, and lung) were overexpressed in emphysematous lesions. The differences in gene expression were detected in fibrotic and emphysematous lesions in CPFE patients. We propose that the development of coexisted fibrotic and emphysematous lesions in CPFE is implemented by these different patterns of gene expressions. Lung tissue specimens from fibrous lesions and emphysematous lesions of 3 patients with combined pulmonary fibrosis and emphysema (CPFE) were obtained for RNA extraction and hybridization on Affymetrix microarrays. We hypothesized that coexisted fibrosis and emphysema in CPFE are programmed by differential gene expressions in the corresponding lesions in the lungs of smokers susceptible to CPFE. Given the importance of genetic susceptibility in understanding the etiology and pathogenesis of CPFE, we examined tissues from patients with CPFE to systemically identify genes significantly expressed in lung tissues with fibrotic lesions as well as genes significantly expressed in tissues with emphysematous lesions.

Project description:Pulmonary hypertension worsens outcome in left heart disease. Stiffening of the pulmonary artery may drive this pathology by increasing right ventricular dysfunction and lung vascular remodeling. We showed that pulmonary arteries from patients with left heart disease are characterized by increased stiffness that correlates with impaired pulmonary hemodynamics. Pulmonary arteries in left heart disease patients with pulmonary hypertension were characterized by degradation of elastic fibers paralleled by an accumulation of fibrillar collagens. We utilized RNA sequencing to identify differentially expressed genes regulating extracellular matrix remodeling in pulmonary arteries of left heart disease patients with or without pulmonary hypertension, in comparison to healthy-heart donor controls. As such we identified that transcriptional deregulation of extracellular matrix constituents and their regulators precedes clinical pulmonary hypertension, and therefore might be a pathomechanism that drives pulmonary arterial remodeling and stiffening in left heart disease.
