Project description:We compare the transcriptome of gnotobiotic Ae. aegypti generated by contaminating axenic (bacteria-free) larvae with bacterial isolates found in natural mosquito breeding sites. We focused on four bacterial isolates (Lysobacter, Flavobacterium, Paenibacillus and Enterobacteriaceae) and found that different gnotobiotic treatments resulted in massive transcriptomic changes throughout the mosquito development.

Project description:Sequencing of the Aedes aegypti genome has enabled genome-wide studies of gene expression in this mosquito. The large quantities of data produced from such studies require efficient cataloguing in order for new insight to be made into gene expression patterns and the underlying molecular mechanisms for producing these patterns. Our study provides a comprehensive catalogue of genes whose transcription products increase or decrease in abundance in adult females following blood feeding. We developed a publicly-accessible database and data-mining tool, aeGEPUCI, that integrates 1) stage-specific microarray analyses of gene expression in Ae. aegypti, 2) functional gene annotation, 3) genomic sequence data, and 4) computational sequence analysis tools. The database is accessible from the address http://www.aegep.bio.uci.edu.

Project description:Aedes aegypti mosquitoes are important vectors of viral diseases. Mosquito host factors play important roles in virus control and it has been suggested that Dengue virus replication is regulated by Dnmt2-mediated DNA methylation. However, recent studies have shown that Dnmt2 is a tRNA methyltransferase and that Dnmt2-dependent methylomes lack defined DNA methylation patterns, thus necessitating a systematic re-evaluation of the mosquito genome methylation status. We have now searched the A. aegypti genome for candidate DNA modification enzymes. This failed to reveal any known (cytosine-5) DNA methyltransferases, but identified homologues for the Dnmt2 tRNA methyltransferase, the Mettl4 (adenine-6) DNA methyltransferase, and the Tet DNA demethylase. All genes were expressed at variable levels throughout mosquito development. Mass spectrometry demonstrated that DNA methylation levels were several orders of magnitude below the levels that are usually detected in organisms with DNA methylation-dependent epigenetic regulation. Furthermore, whole-genome bisulfite sequencing failed to reveal any evidence of defined DNA methylation patterns. These results suggest that the A. aegypti genome is unmethylated. Interestingly, additional RNA bisulfite sequencing provided evidence for Dnmt2-mediated tRNA methylation in mosquitoes. These findings have important implications for understanding the mechanism of Dnmt2-dependent virus control.
