Transcriptome profile of fibroblasts in chronic thromboembolic pulmonary hypertension

Project description:The hallmark of chronic thromboembolic pulmonary hypertension (CTEPH) is fibrotic transformation of pulmonary arterial thrombus, leading to mechanical obstruction of pulmonary arteries. We report the transcriptome profile of fibroblasts isolated from pairs of CTEPH thrombus and pulmonary artery adventitia of the same patient. Fibroblasts isolated from CTEPH thrombus demonstrated upregulation of genes associated with the TGF-β pathway indicating that TGF-β upregulation is associated with the intravascular remodeling process.

Transcriptional changes of the extracellular matrix in chronic thromboembolic pulmonary hypertension governs right ventricle remodeling and recovery [ext327_rnaseq]

Project description:The present prospective study included a total number of 3 patients with a final diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH), who were treated by pulmonary endarterectomy (PEA) at the Kerckhoff Heart and Thorax Center between 2016 and 2020. Biopsies of the myocardial interventricular septum from 3 patients were collected at baseline (BL) before PEA surgery (pre-septal-PEA) In this case, to account for technical and safety aspects, the specimens were taken from the myocardial interventricular septum. The aim of the Study was a comparative characterization of RNA-profiles of septum in CTEPH patients after PEA surgery (postPEA) compared to before PEA surgery (pre-septal-PEA).

Transcriptional changes of the extracellular matrix in chronic thromboembolic pulmonary hypertension governs right ventricle remodeling and recovery [ext128_rnaseq]

Project description:The present prospective study included a total number of 9 patients with a final diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH), who were treated by pulmonary endarterectomy (PEA) at the Kerckhoff Heart and Thorax Center between 2016 and 2020. Biopsies of theright ventricularfreewall from9patients were collected at baseline (BL) before PEA surgery (prePEA). Patients were grouped in severe and moderate risk groups according to 1 year mortality risk by applying a modified version of the European Society of Cardiology (ESC) guidelines risk stratification model according to their BL characteristics. The aim of the Study was a comparative characterization of RNA-profiles in CTEPH patients with disease status at baseline prior to PEA therapy

Heart ventricles proteomic profile in pulmonary arterial hypertension

Project description:Arterial pulmonary hypertension is a rare disease, with little knowledge regarding its etiology, and high mortality. Development of right and later on also left ventricular heart insufficiency, secondary to pulmonary hypertension, is a negative predictive factor. Genetic and molecular processes underlying left heart ventricle remodeling over the course of pulmonary hypertension remain unknown. In particular, there is no knowledge regarding the mechanisms of left heart ventricle atrophy which was completely avoided by researchers until recently.The aim of this study was to assess changes in protein abundance in left and right heart ventricle free wall of rats in monocrotaline model of PAH.

Hypoxic pulmonary hypertension study

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

Anti-proliferative effect of selexipag active metabolite MRE-269 on pulmonary arterial smooth muscle cells from patients with chronic thromboembolic pulmonary hypertension

Project description:Chronic thromboembolic pulmonary hypertension (CTEPH) is a group 4 pulmonary hypertension (PH) characterized by non-resolving thromboembolism in the central pulmonary artery and vascular occlusion in the proximal and distal pulmonary artery. Medical therapy is chosen for patients who are ineligible for pulmonary endarterectomy or balloon pulmonary angioplasty or who have symptomatic residual PH after surgery or intervention. Selexipag, an oral prostacyclin receptor agonist and potent vasodilator, was approved for CTEPH in Japan in 2021. To evaluate the pharmacological effect of selexipag on vascular occlusion in CTEPH, we examined how its active metabolite MRE-269 affects platelet-derived growth factor-stimulated pulmonary arterial smooth muscle cells (PASMCs) from CTEPH patients. MRE-269 showed a more potent anti-proliferative effect on PASMCs from CTEPH patients than on those from normal subjects. DNA-binding protein inhibitor genes ID1 and ID3 were found by RNA sequencing and real-time quantitative polymerase chain reaction to be expressed at lower levels in PASMCs from CTEPH patients than in those from normal subjects and were upregulated by MRE-269 treatment. ID1 and ID3 upregulation by MRE-269 was blocked by co-incubation with a prostacyclin receptor antagonist, and ID1 knockdown by small interfering RNA transfection attenuated the anti-proliferative effect of MRE-269. ID signaling may be involved in the anti-proliferative effect of MRE-269 on PASMCs. This is the first study to demonstrate the pharmacological effects on PASMCs from CTEPH patients of a drug approved for the treatment of CTEPH. Both the vasodilatory and the anti-proliferative effect of MRE-269 may contribute to the efficacy of selexipag in CTEPH.

Transcriptional changes of the extracellular matrix in chronic thromboembolic pulmonary hypertension governs right ventricle remodeling and recovery [ext395_rnaseq]

Project description:The present prospective study included a total number of 71 patients with a final diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH), who were treated by pulmonary endarterectomy (PEA) at the Kerckhoff Heart and Thorax Center between 2016 and 2020. Biopsies of the free right ventricular wall from 71 patients were collected at baseline (BL) during PEA. In a subgroup of 24 patients, myocardial interventricular septum biopsie were obtained during right heart catheterization (RHC) 12 months after PEA (postPEA) In this case, to account for technical and safety aspects, the specimens were taken from the myocardial interventricular septum. Patients were grouped in severe, intermediat and moderate risk according to 1 year mortality risk by applying a modified version of the European Society of Cardiology (ESC) guidelines risk stratification model according to their BL characteristics. The aim of the Study was: a) A comparative characterization of RNA-profiles in CTEPH patients with disease status at baseline prior to PEA therapy; b): An assessment of dynamics of the RNA-profiles in CTEPH patients pre and post PEA.
