Abstract

Brown fat and obesity Brown fat tissue can act to counteract obesity, by burning calories to produce heat, whereas white fat acts as an energy store. Bruce Spiegelman and colleagues reported in Nature last year that brown fat cells are closely related to skeletal muscle, and that the protein PRDM16 can instruct muscle stem cells to become brown fat cells. Now from the same lab comes the finding that PRDM16 works together with C/EBP-β and that expression of this transcriptional unit is sufficient to induce a fully functional brown fat in naive fibroblasts. Transplantation of such fibroblasts into mice creates a brown fat pad that acts as a sink for glucose. This work could lead to new approaches to controlling metabolic disorders such as obesity and type-2 diabetes.
