Brown adipose tissue (BAT) regulates homeostatic energy balances in response to physiological changes such as nutrition intake, calorie restriction, exercise, and environmental temperature by consuming energy to generate heat, and thus serves as an important organ for obesity and metabolic diseases. We performed an integrated transcriptomic and metabolomic characterization of developing mouse BAT from embryo to adult to obtain a time-resolved picture of BAT development. We demonstrated that there are 2 distinct developmental changes that are BAT specific. We also examined transcription factor binding sites and discovered key transcription factors in the developmental time course. A comparison of our data with other organ development transcriptome and metabolome data revealed BAT-specific transcriptome and metabolome patterns. Our findings provide an overview of mouse BAT development as well as implications for developmental and functional BAT controls.
