Mammalian adipose tissues can be broadly divided into white adipose tissue(WAT), beige adipose tissue, and brown adipose tissue(BAT)[1]. The function of WAT is to store superfluous energy and is characterized by unilamellar lipid droplets. WAT, as a prominent endocrine organ, regulates feeding and satiety by producing hormones. Compared with WAT, beige adipose tissue has some smaller multilocular lipid droplets and is located in WAT depots. However, BAT contains an abundance of mitochondria, uncoupling protein-1(UCP1), and multilocular lipid dr...
