  The present invention provides mice that have had their PTP-1B genes disrupted by targeted homologous recombination. The mice have no detectable PTP-1B protein, yet appear to be physiologically normal. However, in the fed state on a normal diet, the mice have half the level of circulating insulin as their wild-type littermates. In glucose and insulin tolerance tests, the mice show an increased insulin sensitivity. When fed a high fat, high carbohydrate diet, the mice show a resistance to weight gain as compared to their wild-type littermates. Methods of making the mice and cell lines derived from the mice are also provided. The present invention also provides methods of identifying inhibitors of the enzymatic activity of PTP-1B as well as inhibitors identified by such methods.

  本发明提供了通过定向同源重组破坏 PTP-1B 基因的小鼠。这些小鼠体内检测不到 PTP-1B 蛋白，但似乎生理正常。然而，在正常饮食的进食状态下，这种小鼠的循环胰岛素水平只有野生型同系小鼠的一半。在葡萄糖和胰岛素耐受性测试中，小鼠对胰岛素的敏感性有所提高。当喂食高脂肪、高碳水化合物饮食时，与野生型同系小鼠相比，小鼠表现出体重增加的抵抗力。本发明还提供了制造这种小鼠和衍生自这种小鼠的细胞系的方法。本发明还提供了鉴定 PTP-1B 酶活性抑制剂的方法以及通过这种方法鉴定的抑制剂。
