Proteomics and Metabolomics based analysis of Metabolic changes in a swine model of Pulmonary Hypertension


ABSTRACT: Pulmonary vein stenosis (PVS) is a rare type of Pulmonary Hypertension (PH), which impacts the flow and pressure within the lung tissue and vasculature resulting in endothelial dysfunction and metabolic changes. We used a pig model in order to mimic PH post PVS using pulmonary vein banding (PVB) of the lower lobes for 12 weeks to investigate the alteration of pressure and flow which provides an impetus for development of PH. In order to develop site-specific therapies, our current study aimed to employ proteomics and metabolomics on both the upper and lower lobes of the pig lung to identify compartment-specific metabolic alterations.

Pulmonary vein stenosis (PVS) causes a rare type of pulmonary hypertension (PH) by impacting the flow and pressure within the pulmonary vasculature, resulting in endothelial dysfunction and metabolic changes. A prudent line of treatment in this type of PH would be targeted therapy to relieve the pressure and reverse the flow-related changes. We used a swine model in order to mimic PH after PVS using pulmonary vein banding (PVB) of the lower lobes for 12 weeks to mimic the hemodynamic profile ass  ...[more]
