We demonstrate biomarker profiles with high-resolution magic angle spinning proton MR spectroscopy (HRMAS H1 MRS) of live Drosophila melanogaster flies. We show that the metabolic HRMAS MRS profiles of adipokinetic hormone receptor (akhrnull) mutant flies, which have an obesity phenotype, are different from isogenic control strain flies (akhrrev). Our approach advances the development of novel, in vivo, non-destructive research approaches in Drosophila, suggests biomarkers for investigation of biomedical paradigms, and thus may contribute to novel therapeutic development in obesity.
