Project Details

RNA editing, principally A-to-I editing, is the most prevalent form of RNA base modification and can lead to structural and functional changes in RNA and any subsequently encoded protein. Genomically encoded adenosine (A) is converted to inosine (I) in double stranded RNA (dsRNA) substrates. Inosine is interpreted as a guanine (G) during translation, thus harboring the potential to alter the protein coding sequence of mRNA substrates. However, A-to-I editing predominantly occurs in non-coding, repetitive elements such as inverted Alu elements and short interspersed elements (SINE). Estimates of the number of editing sites range from hundreds of thousands to millions in human cells, with tens of thousands in the mouse. Our recent work has defined a close link between ADAR1, RNA editing and the innate immune system (see Hartner et al Nat Immunol 2009; Liddicoat et al, Science 2015; Liddicoat et al Exp Hematology 2016; Heraud-Farlow et al J Mol Med 2016; Heraud-Farlow et al Genome Biol 2017). This project will apply unique mouse models and genome wide screening to definitively understand the consequences of ADAR1 editing on non-coding and small RNA species.

The project will involve both wet (tissue culture, primary cell models, RNA biology) and dry lab approaches (computational analysis, bioinformatics).

Skills focus: haematology analysis, PCR, RNA structure, cell culture, RNA-seq, statistics, python & R, qPCR, gene expression, westerns, Crispr screening.

This project is conducted in St Vincent’s Institute of Medical Research, Cancer and RNA Biology Laboratory.
