(Submitter supplied) The hypothesis tested in this study was that chronic exposure of PBMCs to a hypertensive environment in remodeled pulmonary vessels would be reflected by specific transcriptional changes in these cells. The transcript profiles of PBMCs from 30 idiopathic pulmonary arterial hypertension patients (IPAH), 19 patients with systemic sclerosis without pulmonary hypertension (SSc), 42 scleroderma-associated PAH patients (SSc-PAH), and 8 patients with SSc complicated by interstitial lung disease and PH (SSC-PH-ILD) were compared to the gene expression profiles of PBMCs from 41 healthy individuals.

(Submitter supplied) 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). more...

(Submitter supplied) Systemic sclerosis (SSc) is an autoimmune disease characterized by clinical heterogeneity, multi-organ involvement, and complex genetic risk. Here, we report the first multi-tissue meta-analysis of ten independent SSc gene expression datasets. We identify a common immune-fibrotic expression axis across all tissues that is associated with the most severe disease phenotypes. The coexpression patterns conserved across tissues and phenotypes were used to query functional genomic networks, which allowed us to identify common and tissue-specific disease drivers. more...

(Submitter supplied) The study looked at changes in gene expression profiles in subjects with Pulmonary Arterial Hypertension and Scleroderma (PAH-SSc) before and after treatment with Tadalafil. A total of ten subjects were enrolled and various clinical assessments including 6-minute walk tes, cardiac MRI and right heart catheterization were done in addition to gene expression study.

(Submitter supplied) Objective. Previous observations suggest that active systemic juvenile idiopathic arthritis (sJIA) is associated with a prominent erythropoiesis gene expression signature. The aim of this study was to determine the association of this signature with peripheral blood mononuclear cell (PBMC) subpopulations and its specificity for sJIA as compared to related conditions. 125 patients with JIA (18 sJIA and 107 non-sJIA) and 29 controls were studied. more...

(Submitter supplied) Limited systemic sclerosis patients with pulmonary arterial hypertension show biomarkers of inflammation and vascular injury Forty-nine PBMC samples were obtained from 21 lSSc subjects without PAH (lSSc-noPAH), 15 lSSc subjects with PAH (lSSc-PAH), and 10 healthy controls; three subjects provided PBMCs one year later. Genome-wide gene expression was measured for each sample. Gene expression clearly distinguished lSSc samples from healthy controls, and separated lSSc-PAH from lSSc-NoPAH patients. more...

(Submitter supplied) Genes dysregulated in cystic fibrosis (CF) and primary pulmonary arterial hypertension (PAH) at a late stage of pulmonary failure are still largely unknown. Blood samples taken in the frame of the French cohort of lung transplantation COLT offers the opportunity to identify in blood specific gene signatures of each disease and a common gene signature for both pathologies. A microarray analysis was performed with homogeneous groups of CF patients (n=23), PAH (n=13) patients and healthy volunteers (n=28). more...

(Submitter supplied) Aberrantly remodeled vasculature in pulmonary arterial hypertension (PAH) features a prominent inflammatory cell infiltrate suggesting that immune effector cells may contribute to disease progression. Global expression studies of peripheral blood mononuclear cells (PBMCs) and whole blood have attempted to better define this inflammatory component of PAH pathobiology.

(Submitter supplied) Purpose: This study aimed to explore the pathobiological markers of sarcoidosis in PBMCs by comparing the transcriptional signature of PBMCs from patients with pulmonary sarcoidosis and those of healthy controls by RNA sequencing. Methods:PBMC samples were collected from subjects with pulmonary sarcoidosis with no steroid/immunosuppressant drugs (n = 8) and healthy controls (n = 11) from August 2020 to April 2021, and RNA sequencing was performed with the PBMC samples. more...

(Submitter supplied) Preserving the in vivo cell transcriptome is essential for accurate profiling, yet factors during cell isolation including time ex vivo and temperature induce artifactual gene expression, particularly in stress-responsive immune cells. In this study, we investigated two methods to mitigate ex vivo activation signature gene (ASG) expression in peripheral blood mononuclear cells (PBMCs): transcription and translation inhibitors (TTis) and cold temperatures during isolation. more...

(Submitter supplied) Rationale: Pulmonary arterial hypertension (PAH) is characterized by increased pulmonary artery pressure and vascular resistance, typically leading to right heart failure and death. Current therapies improve quality of life of the patients but have a modest effect on long-term survival. A detailed transcriptomics and systems biology view of the PAH lung is expected to provide new testable hypotheses for exploring novel treatments. more...
