BSc Research Project: The Role of Homeobox Genes and Retinoic Acid in the development of the chick hindbrain 

During this project, Dr Duncan identified the presence of specific homeobox gene via immunolocalisation for a transient period during the development of chick hindbrain. She then tested the hypothesis that retinoic acid may be acting locally as a switch on the identified homebox gene engrailed. Teratogenic effects were observed secondary to retinoic acid at sites of engrailed expression. 

Dr Duncan was responsible for doing all the lab work including microscopic dissection of the chick embryos, preparation for immunocytochemistry and interpretation of the results.

Research during the year as Glaxo Paediatric Respiratory Research Fellow 

Dr Duncan was responsible for the recruitment of children with asthma to a randomised double-blind, double-dummy 2-way crossover trial comparing the effects of fluticasone propionate nebules and prednisolone tablets on the hypothalamic-pituitary- adrenal axis in children with asthma. They were looking at the safety aspects. The results found that fluticasone propionate had a significantly smaller effect on HPA axis that prednisolone in doses used in the acute setting. As well as recruiting and consenting the children and their parents she visited them at home to record data and collect samples and they had my pager as an emergency contact.   

She was responsible for setting up a pilot study looking at using different concentrations of nebulised saline to induce sputum production in children whose asthma was stable at the time and non-asthmatic controls. This was to allow for the analysis of their sputum initially for inflammatory cells and then to measure leukotriene levels.
