摘要: 蛋白质酪氨酸磷酸酶1B(PTP1B)是一种在体内广泛表达的胞内蛋白质酪氨酸磷酸酶,在调节胰岛素敏感性和能量代谢的过程中起着重要作用。通过抑制PTP1B可增加胰岛素和瘦蛋白(leptin)的活性, 为寻找2型糖尿病、肥胖的治疗提供了光明前景。

Abstract: PTP1B is a ubiquitously expressed intracellular protein tyrosine phosphatase. Several lines of evidence support an important role for protein tyrosine phosphatase 1B(PTP1B) in metabolism, and specially in type 2 diabetes and obesity. Overexpression of PTP1B protein has been observed in insulin-resistant states associated with obesity. PTP1B is a negative regulator of insulin and leptin signaling, PTP1B inhibitors might be efficacious in the treatment of type 2 diabetes and obesity by increasing insulin and leptin sensitivity.
