Identification of Exosomal microRNA signature by liquid biopsy in Hereditary Hemorrhagic Telangiectasia patients

Project description:Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant vascular dysplasia characterized by epistaxis, mucocutaneous telangiectases, and arteriovenous malformations (AVM) in visceral organs. In this study, we carried out a liquid biopsy consisting in the isolation of total RNA from plasma exosomes samples from HHT type 1 (HHT1 group) and type 2 (HHT2 group) patients, and healthy relatives (Control group). Upon gene expression data processing and normalization, a bioinformatics analysis was performed for the study of principal components, hierarchical clustering and pairwise comparisons between HHT samples and control group. Results were evaluated in a further validation cohort of HHT and healthy donors by real time PCR and the diagnosis value of exosomal miRNA determined by the ROC curves analysis. We found that exosomal miRNA expression signature clearly distinguishes among healthy and HHT samples and types. Thus, we identified a disease-associated molecular fingerprint of 35 miRNAs over-represented, being 8 specifics for HHT1 and 11 for HHT2; and 30 under-represented, including 9 distinctive for HHT1 and 9 for HHT2. These exosome-transported miRNAs have diagnosis value for HHT, and even allow to distinguish between HHT1 and HHT2.

Single cell RNA analysis of lung endothelial cells in mouse model of Hereditary Hemorrhagic Telangiectasia 2

Project description:Arteriovenous malformations (AVMs) are characteristic of hereditary hemorrhagic telangiectasia (HHT). We used single cell RNA sequencing (scRNA-seq) to analyzed the pulmonary ECs in mice with endothelial-specific deletion of Alk1 gene.

Induced Endothelial Cell Cycle Arrest Prevents Arterio-venous Malformations in Hereditary Hemorrhagic Telangiectasia (Bulk RNA-Seq)

Project description:Distinct endothelial cell cycle states (early G1 vs. late G1) provide different “windows of opportunity” to enable the differential expression of genes that regulate venous and arterial specification, respectively. Endothelial cell cycle control and arterial-venous identities are disrupted in vascular malformations including arteriovenous (AV) shunts which is a hallmark of hereditary hemorrhagic telangiectasia (HHT). We show how endothelial cell late G1 arrest induced by Palbociclib modulates the expression of genes regulating arterio-venous identity and prevents AVM development induced by BMP9/10 inhibition.

Identification of Exosomal MicroRNA Signature by Liquid Biopsy in Hereditary Hemorrhagic Telangiectasia Patients.

Project description:Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant vascular dysplasia characterized by epistaxis, mucocutaneous telangiectases, and arteriovenous malformations (AVM) in the visceral organs. The diagnosis of HHT is based on clinical Curaçao criteria, which show limited sensitivity in children and young patients. Here, we carried out a liquid biopsy by which we isolated total RNA from plasma exosome samples. A cohort of 15 HHT type 1 patients, 15 HHT type 2 patients, and 10 healthy relatives were analyzed. Upon gene expression data processing and normalization, a statistical analysis was performed to explore similarities in microRNA expression patterns among samples and detect differentially expressed microRNAs between HHT samples and the control group. We found a disease-associated molecular fingerprint of 35 miRNAs over-represented in HHT vs. controls, with eight being specific for HHT1 and 11 for HHT2; we also found 30 under-represented, including nine distinct for HHT1 and nine for HHT2. The analysis of the receiver operating characteristic (ROC) curves showed that eight miRNAs had good (AUC > 75%) or excellent (AUC > 90%) diagnosis value for HHT and even for type HHT1 and HHT2. In addition, we identified the cellular origin of these miRNAs among the cell types involved in the vascular malformations. Interestingly, we found that only some of them were incorporated into exosomes, which suggests a key functional role of these exosomal miRNAs in the pathophysiology of HHT.
