Number of places

1

Opens

11 December 2020

Duration

36 Months

Eligibility

Candidates will have a B.Sc. in Biological Science, biomedical Engineering or a closely related field at Upper Second Class or above or overseas equivalent. M.Sc. with project experience is a plus. Ideal candidates will also have prior experience in cardiovascular physiology and biological measurements.

Project Details

Pulmonary arterial hypertension (PAH) results in right ventricular (RV) dysfunction due, in part, to RV ischemia. Both RV capillary rarefaction and reduced right coronary artery perfusion contributes to RV ischemia and their relative contribution is unknown. It is also uncertain whether increasing right coronary artery perfusion would improve RV function. We hypothesize that increasing right coronary artery perfusion improves RV function in PAH.

 

The goal of this project is to examine the role of right coronary artery perfusion on right ventricular function and identify novel, promising therapeutic targets for PAH. This project will investigate RV function with a sustained increase of right coronary artery perfusion pressure achieved via supra-aortic banding in preclinical animal models of PAH. Transcriptomic and/or proteomic profiles will be assessed to explore the pathways and proteins that are altered in PAH and also restored by the increase of right coronary artery perfusion pressure. These pathways and proteins will be validated in cellular studies in vitro and in animal studies in vivo and constitute potential therapeutic targets for PAH.

 

Techniques used:

Rodent animal surgery, hemodynamic measurement and tissue harvest

Cell isolation and culture, and siRNA approach

Cellular biology assessments including PCR and immunoblotting

Immunohistochemistry

Confocal Imaging

Proteomics
