  • Title: Effects of sucrose feeding and denervation on lipogenesis in brown adipose tissue.
    Author: Granneman JG, Campbell RG.
    Journal: Metabolism; 1984 Mar; 33(3):257-61. PubMed ID: 6694566.
    Abstract:
    Rats were fed standard laboratory chow or sucrose + chow for 2-3 weeks. Sucrose feeding significantly increased the size and norepinephrine content of interscapular brown adipose tissue (BAT). Sucrose feeding stimulated in vivo lipogenesis in BAT, white adipose tissue, and liver. Unilateral denervation reduced BAT norepinephrine content by 90%, and significantly reduced BAT protein and DNA content. Prior surgical denervation of BAT had no effect on lipogenesis in chow-fed rats, but reduced the sucrose-induced lipogenesis in BAT by 75% and increased lipogenesis in retroperitoneal white adipose tissue of sucrose-fed rats. These data demonstrate that the optimal stimulation of lipogenesis in BAT by sucrose feeding requires innervation of this tissue.
