IPAH signatures in hPASMC and hAdvFB

ABSTRACT: Microarray analyisis of human pulmonary artery smooth muscle cells (hPASMC) and adventitial fibroblasts (hPF) from donor and IPAH lungs will give an indication of possible differentially regulated genes. The mRNA was obtained from cells with passage 1 (n=4/group).There was no treatment applied, we investigate the baseline differences.

miRNA profiling in hPASMC isolated from normal and PAH patients

Project description:To identify dysregulated miRNAs in PAH HPASMC, we compared the miRNA expression profiles between normal and PAH HPASMC using the RT2 miRNA PCR Array System. Total RNA was isolated using a miRNeasy Mini Kit (Qiagen, Valencia, CA) and treated with an RNase-Free DNase Set (Qiagen). After quantification with Nanodrop 2000 spectrophotometer (ThermoScientific, Rockford, IL), miRNAs were reversely transcribed using a RT2 miRNA First Strand Kit (SABiosciences, Frederick, MD). The RT2 miRNA PCR Array System (SABiosciences) was used to study miRNA profiling in normal and PAH HPASMC. U6, SNORD44, SNORD47 and SNORD48 were used as internal controls for the profiling. HPASMC isolated from oe normal donor (C128, as control), one IPAH patient (B157), one PAH patient with Eisenmenger’s syndrome (CC-008) and one PAH patient with Scleroderma (CCF-004) were used for miRNA PCR array study. Data is normalized to the control sample. Three independent sample preparations were used for this study.

RNAseq of Extracellular vesicle RNAs and cellular RNAs from HPASMCs with or without TGF-b1 or BMP4 treatment

Project description:Excessive TGF-β signalling has been shown to underlie pulmonary hypertension (PAH). Human pulmonary artery smooth muscle cells (HPASMCs) can release extracellular vesicles (EVs) but their content and significance have not yet been studied. Here, we analysed the content and biological relevance of HPASMC-derived EVs. We used low-input RNA-Seq to analyse the RNAs of EVs released by HPASMC under basal conditions. This data was compared to cellular RNAs. The same experiments (RNA-seq of EV and cellular RNAs) were carried out on HPASMC treated with TGF-b1 and BMP4, recapitulating pathological conditions.

Single cell RNA sequencing for mouse femoral artery

Project description:Rapid regeneration of smooth muscle after vascular injury is essential for maintaining proper artery function. The current view holds that pre-existing smooth muscle proliferate and expand in responding to vascular injury, contributing to virtually all new smooth muscle cells. Whether resident vascular stem cells for smooth muscle exist remains controversial and their putative functional role for artery repair and regeneration is elusive. Here we performed cell fate mapping and single cell RNA sequencing to identify Sca1+ vascular stem cells (VSCs) residing in the adventitial layer of artery wall.

Digital Spatial Profiling identifies distinct molecular signatures of vascular lesions in Pulmonary Arterial Hypertension

Project description:Idiopathic Pulmonary Arterial Hypertension (IPAH) is a severe human disease, characterized by extensive pulmonary vascular remodeling due to plexiform and obliterative lesions, media hypertrophy, and alterations of adventitia. The objective of the study was to test the hypothesis that microscopic IPAH vascular lesions express unique molecular profiles, which collectively are different from control pulmonary arteries. We used digital spatial transcriptomics to profile the genome-wide differential transcriptomic signature of key pathological lesions (plexiform, obliterative, intima+media hypertrophy, and adventitia) in IPAH lungs (n= 11) and compared these data to the intima+media and adventitia of control pulmonary artery (n=5). The IPAH lesions and pulmonary artery compartments were defined by the analyses of hematoxylin-eosin stained serial section, aided by labeling with CD31 (for endothelial cells), smooth muscle cell actin (SMA), and CD45 for inflammatory mononuclear cells, also in serial sections. Approximately 12 regions of interest (ROI) were sampled from a histological section of a paraffin-embedded block of each lung, which was selected based on the finding of enrichment for IPAH lesions or control pulmonary arteries.

Transcription profiling of human normal subjects and IPAH patients to examine the effect of BMP-2 on pulmonary artery smooth muscle cells

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.
