A recent surge in obesity has given impetus to better understand the mechanisms of adipogenesis, particularly brown adipose tissue (BAT) due to its potential utilization for anti-obesity therapy. Postnatal brown adipocytes arise from early muscle-progenitors but how brown fat lineage is determined is not completely understood. Here, we show that a multifunctional protein EWS (Ewing Sarcoma) is essential for determining brown fat lineage during development. BATs from Ews-null embryos and newborns are developmentally arrested. Ews mutant brown preadipocytes fail to differentiate due to loss of Bmp7 expression, a critical early brown adipogenic factor. We demonstrate that EWS, along with its binding partner YBX1 (Y-box binding protein 1), activates Bmp7 transcription. Depletion of either Ews or Ybx1 leads to loss of Bmp7 expression and brown adipogenesis. Remarkably, Ews-null BATs and brown preadipocytes ectopically express myogenic genes. These results demonstrate that EWS is essential for early brown fat lineage determination.
