Study IDST000102
Study TitleCold adaptation shapes the robustness of metabolic networks in Drosophila melanogaster
Study TypeTime course during cold exposure for four genetic lines of flies
Study SummaryMetabolites of cold hardy versus cold susceptible flies were compared using N less than R-based metabolomics. We used 8 replicates per line (2 hardy lines, two susceptible lines), and sampled each line at three time points (before, during and after cold), giving rise to 96 samples total.

Project Title:Cold adaptation shapes the robustness of metabolic networks in Drosophila melanogaster
Project Type:Genetic study
Project Summary:Flies that had been selected for fast and slow recovery from a cold-coma (2 replicates of each type) were sampled before, during (at the end of a 3h cold exposure at 0 degC), and after 5 min recovery from cold exposure. We tested the hypothesis that cold adaptation remodelled metabolic networks to make them more robust to the effects of cold.
