Global expression analyses demonstrate that alterations in miRNA levels correlate with various metabolic diseases. miRNAs regulate central metabolic pathways and thus play vital roles in maintaining organismal energy balance and metabolic homeostasis. Here we highlight novel sequencing technologies used to comprehensively define the target spectrum of miRNAs in metabolic disease that complement recent literature reporting physiologic roles for miRNAs in the regulation of glucose and lipid metabolism in peripheral tissues of animal models of metabolic dysfunction. These emerging technologies help decipher the complexity of the miRNA interactome and enrich our understanding of how miRNAs mediate physiologic effects by targeting a spectrum of gene transcripts simultaneously. miRNA-based therapeutics emerge as a viable strategy for treating metabolic diseases.
