Disclosed is a transgenic knockout mouse whose genome has a homozygous disruption in its endogenous Gpx1 and Gpx2 genes, wherein the disruptions result in a decrease in GPX activity in the transgenic mice when compared to non transgenic mice of the same type. Methods for production of the mouse are presented. Also disclosed are cells derived from the transgenic knockout mouse. The invention further provides a mouse model for the disorders of ileitis, colitis,inflammatory bowel disease, ileal cancer and myeloleukemia. The mouse can be used in a method for identifying therapeutic agents for the treatment of an individual diagnosed with one or more of said disorders.
本发明公开了一种转
基因基因敲除小鼠,其
基因组中的内源 Gpx1 和 Gpx2
基因被同源干扰,与同类型的非转
基因小鼠相比,干扰导致转
基因小鼠的 GPX 活性降低。本文还介绍了生产这种小鼠的方法。还公开了从转
基因基因敲除小鼠中提取的细胞。本发明进一步提供了回肠炎、结肠炎、炎症性肠病、回肠癌和骨髓白血病等疾病的小鼠模型。该小鼠可用于鉴定治疗被诊断患有一种或多种上述疾病的个体的治疗药物的方法中。
