- Description: Genomic analysis of DV117 revealed a significantly higher frequency of A-to-G substitutions when compared to LN40. Furthermore, detailed analysis of dinucleotide editing showed that A-to-G mutations had a preference for 5'TpA and 5'ApA. These results strongly implicated the activity of the adenosine deaminase, ADAR1, in this type of mutation. Further investigation demonstrated that overexpression of donkey ADAR1 increased A-to-G mutations within the genome of EIAV. Together with our previous finding that multiple mutations in multiple genes are generated in DV117 during its adaptation from horses to donkeys, the present study suggests that ADAR1-induced A-to-G mutations occur during virus adaption to related new hosts contributing to the alteration of EIAV host tropism.
