  • Title: Responses to cafeteria feeding in mice after the removal of interscapular brown adipose tissue.
    Author: Connolly E, Carnie JA.
    Journal: Biosci Rep; 1982 Nov; 2(11):877-82. PubMed ID: 6297631.
    Abstract:
    Feeding a cafeteria diet to mice resulted in an increased energy intake of approximately 30% and this led to increases in the wet weight, total protein content, and total cytochrome oxidase activity of interscapular and dorso-cervical brown adipose tissue. Surgical removal of interscapular brown adipose tissue, followed by cafeteria feeding, gave rise to an elevation in dorso-cervical brown adipose tissue wet weight, total protein content, and total cytochrome oxidase activity, compared to intact cafeteria-fed mice. Cafeteria feeding with or without the removal of interscapular brown adipose tissue did not lead to significant increases in body weight compared to stock-fed control mice, but both cafeteria-fed groups of mice showed significant elevations in body fat content indicating that the induced hyperphagia led to a relative obesity in the cafeteria-fed groups. The results presented are consistent with an increased thermogenic activity in the brown adipose tissue of cafeteria-fed mice, and the effect of the removal of interscapular brown adipose tissue further indicates the quantitative importance of the tissue in the control of body weight.
