Exploring Effects of Sex and Diet on Drosophila melanogaster Head Gene Expression

Gene expression depends on sex and environment. We stringently explored the contributions of these effects in Drosophila melanogaster by rearing three distinct wildtype genotypes on isocaloric diets either high in protein or sugar followed by expression profiling of heads from the sexes. By using different genotypes as replicates we developed robust sex- and diet-biased expression responses.
