研究领域

Our research interests are to provide insights into how the heart forms during early stages of cardiogenesis. In particular, current interests are focused on the role sarcomeric thick or thin filament structural proteins play in the early developing heart. Heart defects of particular interest in the laboratory are those associated with the developing atrial septa, chamber specification, normal electrical activation of the heart and the formation of the conduction system. Congenital heart defects are relatively common (approximately 0.8% of the population), with most cases having an unknown cause. Our research group uses the chick as a model organism (both in ovo and in vitro), and morpholino technology to perform gene-specific knockdown. A range of developmental, cell and molecular biology techniques are employed to decipher the expression of the genes of interest and the abnormalities seen upon knockdown. Further, functional studies are performed to provide insights into what role the genes play in the heart in order to explain how defects form. In addition, in order to analyse the morphological effects on post-loaded hearts, we have recently optimised banding of the outflow tract of the developing chick heart, with harvesting performed at different stages of development. Dr Loughna runs an active laboratory and currently has three PhD students and one part-time technician.
