最近肥胖人数的激增推动了人们更好地了解脂肪生成的机制,特别是棕色脂肪组织(BAT),因为它具有抗肥胖治疗的潜在用途。出生后棕色脂肪细胞由早期肌肉祖细胞产生,但棕色脂肪谱系是如何确定的尚不完全清楚。在这里,我们证明多功能蛋白 EWS(尤文肉瘤)对于确定发育过程中的棕色脂肪谱系至关重要。来自 Ews 无效胚胎和新生儿的 BAT 发育停滞。 Ews 突变棕色前脂肪细胞由于 Bmp7 表达缺失而无法分化,Bmp7 是一种关键的早期棕色脂肪形成因子。我们证明 EWS 与其结合伙伴 YBX1(Y-box 结合蛋白 1)一起激活 Bmp7 转录。 Ews 或 Ybx1 的缺失会导致 Bmp7 表达丧失和棕色脂肪生成。值得注意的是,Ews-null BAT 和棕色前脂肪细胞异位表达肌源基因。这些结果表明 EWS 对于早期棕色脂肪谱系测定至关重要。
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.
