About the Project

Common heart diseases such as heart failure (HF) and coronary heart disease (CHD) are characterized by cardiomyocyte loss due to necrosis and apoptosis. Whilst it was widely believed that the adult cardiomyocytes are unable to proliferate, recent evidence suggests that these cells have some degree of regenerative capacity.

However, it is clear that the level of myocyte regenerative capacity in adult human heart is insufficient to compensate for the cell loss due to HF or CHD.

One of the main regulators of cardiomyocyte proliferation is the Hippo signalling pathway. Upregulation of YAP activity, the major downstream effector of the Hippo pathway, increases the regenerative capacity of cardiomyocytes as well as cell survival. Through a genetic screen and subsequent analysis in cultured cardiomyocytes we have identified novel genes and microRNAs as possible novel modulators of Hippo-YAP signalling axis.

Based on this pilot data this project will further explore the role of these novel Hippo regulators in modulating cardiomyocyte proliferation and regeneration. We will perform genetic overexpression and gene silencing experiments in primary cardiomyocytes using adenoviral gene delivery system. Cardiomyocyte proliferation rate, apoptosis and cell survival will be determined in basal condition and following pathological stimulation such as hypoxia or treatment with hypertrophic agonist (phenylephrine). In vivo studies using mouse model of myocardial infarction and pressure overload hypertrophy will also be performed. We will overexpress genes and/or microRNAs by using the cardiotrophic adeno-associated virus 9 (AAV9) as delivery vector or using direct intramyocardial injection of mRNA/microRNAs.

This study will provide evidence as to whether genetic modification of a key signalling pathway in cell regeneration (i.e. the Hippo pathway) will enhance the regenerative capacity and cell survival of cardiomyocytes. It will also provide a unique combination of training in molecular biology and in vivo animal physiology for the student.

Entry Requirements

Candidates are expected to hold (or be about to obtain) a minimum upper second class honours degree (or equivalent) in a related area/subject. Candidates with previous laboratory experience are particularly encouraged to apply.
