Research Progress of Key Factors for the Transformation of Adipose Tissue
Abstract: Adipose tissue is divided into brown adipose tissue (BAT) and white adipose tissue (WAT). BAT was a specialized thermogenic tissue, which was the main site of nonshivering thermogenesis in small mammals. PR domain-containing 16 (PRDM16) was a brown adipose determination factor. It was selectively expressed in BAT and induced the expression of α subunit of peroxisome proliferators-activated receptor-γcoactivator-1 (PGC-1α) and uncoupling protein 1. BMP7 could stimulate brown adipocyte differentiation and enhance thermogenesis by activating the expression PRDM16 and PGC-1α genes. COXII, PPARα and PGC-1α were the key regulatory factors of differentiation and metabolism in brown adipocyte. COXII was an effector molecule of adrenergic pathway in WAT. It was necessary for the formation of brown adipocytes. PPARα expression level in BAT was higher than WAT. It could induce the expression of thermogenesis related genes and promote the generation of primary brown adipocyte. PGC-1α also could induce the formation of brown adipocytes in WAT. In the process of brown adipocytes differentiation, PGC-1α expression level increased. In this paper, the key factors of transformation of adipose tissue were studied, and some prospects for the study of the fat tissue transformation of small mammals were given.
