This project examines how adipose tissue regulates systemic metabolism and aging in Drosophila melanogaster through the miRNA-processing enzyme Dicer-1 (Dcr-1). Proteomic profiling of fat bodies from Dcr-1 heterozygous flies was performed to identify molecular changes associated with reduced Dcr-1 activity. The dataset reveals metabolic and stress-response remodeling consistent with reduced insulin/IGF signaling, supporting a model in which decreased Dcr-1 increases Dilp6 expression in the fat body and suppresses Dilp2 secretion from brain insulin-producing cells, promoting longevity.
