Project description:Methionine restriction is known to extend lifespan in various model organisms including Drosophila melanogaster. In this analysis, we performed scRNAseq of Drosophila female midgut samples to understand the cell type specific response to methionine restriction.
Project description:we performed proteome sequencing in Drosophila at day 7 (young) and day 42 (old) under dietary restriction (DR)and ad libitum (AL) conditions.
Project description:Transfer RNAs (tRNAs) are vital in determining the specificity of translation. Mutations in tRNAs can result in the mis-incorporation of amino acids into nascent polypeptides in a process known as mistranslation. Here, our goal was to test the impacts of different types of mistranslation in the model organism Drosophila melanogaster, as impact of mistranslation depends on the type of amino acid substitution. We created two fly lines - one expressing a serine tRNA variant with valine anticodon and the other with a serine tRNA variant with a threonine anticodon. Using mass spectrometry, we measure the amount of mistranslation at various points in fly development.
