白色脂肪组织调节新陈代谢;肥胖症和相关并发症如糖尿病、动脉粥样硬化和癌症的持续流行突出了这种控制的重要性。白色脂肪组织的维持是一个动态的过程,但很少有人知道药理刺激如何影响这种可塑性。结合体内谱系标记和BrdU标记策略,我们发现罗格列酮,噻唑烷二酮类降糖药物的成员,显着增加脂肪祖细胞向脂肪细胞的演变。值得注意的是,长期罗格列酮给药破坏了干细胞区室的成脂和自我更新能力,并改变了其分子特征。这些数据揭示了脂肪动力学的未知方面,并为治疗目的操纵脂肪谱系提供了基础。
White adipose tissue regulates metabolism; the importance of this control is highlighted by the ongoing pandemic of obesity and associated complications such as diabetes, atherosclerosis, and cancer. White adipose tissue maintenance is a dynamic process, yet very little is known about how pharmacologic stimuli affect such plasticity. Combining in vivo lineage marking and BrdU labeling strategies, we found that rosiglitazone, a member of the thiazolidinedione class of glucose-lowering medicines, markedly increases the evolution of adipose progenitors into adipocytes. Notably, chronic rosiglitazone administration disrupts the adipogenic and self-renewal capacities of the stem cell compartment and alters its molecular characteristics. These data unravel unknown aspects of adipose dynamics and provide a basis to manipulate the adipose lineage for therapeutic ends.
