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:We determined the actively translated mRNA induced/repressed by a Dietary Restriction intervention specifically in the differentiated enterocytes of the intestine. For this, we did a "genetic dissection" by expressing a tagged ribosomal subunit (RpL13A-His6FLAG) under the control of the tissue specific Myo1A-GAL4 driver, targetting its expression exclusively to the intestinal enterocytes. By performing a anti-flag pulldown we are then able to enrich our mRNA pool for transcripts that are directly bound to ribosomes and being actively translated. In this manner, we become one step closer to protein synthesis while profiling gene expression.
Project description:Feeding resveratrol to Drosophila melanogaster extends lifespan. Studies of microarray show similarities between calorie/dietary restriction and resveratrol on both a gene expression and biological pathway level.
