PTP1B 是一种非跨膜蛋白酪氨酸磷酸酶,长期以来一直被研究为胰岛素和瘦素信号传导的负调节因子,最近作为肿瘤发生中意想不到的积极因素再次受到关注。在这篇综述中,我们重点介绍了对这种酶的看法是如何从将其视为简单的代谢开关转变为更复杂的观点,即 PTP1B 是一种可以在多种信号通路中发挥消极和积极作用的酶。这些双重特征使 PTP1B 成为糖尿病、肥胖症甚至乳腺癌特别有吸引力的治疗靶点。
PTP1B, a non-transmembrane protein tyrosine phosphatase that has long been studied as a negative regulator of insulin and leptin signaling, has recently received renewed attention as an unexpected positive factor in tumorigenesis. In this review, we highlight how views of this enzyme have evolved from regarding it as a simple metabolic off-switch to a more complex view of PTP1B as an enzyme that can play both negative and positive roles diverse signaling pathways. These dual characteristics make PTP1B a particularly attractive therapeutic target for diabetes, obesity, and perhaps breast cancer.
