About the Project
Following myocardial infarction (MI), extracellular matrix (ECM) remodelling is critical for acute cardiac tissue healing; however, excessive accumulation of ECM during the chronic stage accelerates the progression to heart failure. In our pilot study, we observed that loss of p21 protein activated kinase-2 (Pak2) disposed the mice more vulnerable to myocardial infarction. In this PhD project, we will 1) Generate the mice with Pak2 knockout in myofibroblasts; 2) Characterise how Pak2 knockout in myofibroblasts impacts ECM remodelling after MI; 3) Investigate molecular mechanism whereby Pak2 regulates ECM composition and remodelling following MI. Obtained data will provide new insights in developing novel treatment strategies for MI through targeting Pak2.
Entry Requirements:
Applications should be submitted online and candidates should make direct contact with the Manchester supervisor to discuss their application directly. Applicants must have obtained, or be about to obtain, at least an upper second class honours degree (or equivalent) in a relevant subject.
