David Sharon, B. Sc., Graduate Student



I received my B.Sc. (Honors Biochemistry) from the University of British Columbia. During my undergraduate studies I was also in the Co-op program, which allowed me to work in research labs for two 8-month work terms. One of the work terms was in the Hitt Lab, where I was establishing a new cell line to allow the growth and propagation of adenoviruses encoding toxic genes. After finishing my undergraduate degree I decided to come back to Edmonton for my graduate studies.

My main project is to identify the role of RNA interference (RNAi) in adenoviral replication. Adenoviruses encode two small RNA molecules (VA-RNAs) that were recently found to be processed to viral miRNAs, however, the targets of these miRNAs are currently unknown. Interestingly, adenoviral vectors not encoding these VA-RNAs were found to be oncolytic, and therefore can specifically replicate in certain cancer cells. We would like to determine the targets of these adenoviral miRNAs and the reasons why these miRNAs are not required for replication in cancer cells.
