GK大鼠
品系编号:GAP2020
品系简称:GK
品系特点:
GK大鼠是非胰岛素依赖非肥胖自发Ⅱ型糖尿病大鼠模型。主要表现为胰岛功能不足,胰岛β细胞分泌功能受损,空腹高血糖,肝糖原生成增多,肝脏、肌肉和脂肪组织中度胰岛素抵抗,血脂升高,多尿,并出现各种糖尿病并发症,且不伴随肥胖。表现与人类糖尿病相似的代谢、内分泌和血管疾病。
雄性动物约在14~16周龄时出现II型糖尿病,即出现血糖升高、心率降低、心肌萎缩等症状,与人类Ⅱ型糖尿病心脏病进展极为相似。
遗传学信息:
遗传背景:wistar
品系类型:基因突变

应用领域:
1. 糖尿病发病机制及胰岛素抵抗
2. 糖尿病并发症:与人类疾病相似的视网膜病变、肾病、神经病变和心血管并发症等特征。
