摘要 糖尿病是危害社会发展的重大健康问题之一。虽然病因复杂,但胰岛在血糖稳态调节中的核心作用毋庸置疑。恢复胰岛β细胞的功能和数量一直是临床治疗糖尿病的关键。细胞周期分析显示,胰岛β细胞增殖十分缓慢,绝大多数(97%~99%)处于G0/1期[1-3]。阻止β细胞通过G1/S期周期转换的分子机制尚不清楚。视网膜母细胞瘤蛋白(Rb)是调控G1/S期细胞周期转换的重要分子,与视网膜母细胞瘤样蛋白1(p107)、视网膜母细胞瘤样蛋白2(p130)具有相似的口袋状DNA结合区域,共同属于口袋蛋白家族[3-5]。有关口袋蛋白家族的研究主要集中在肿瘤领域。近年研究显示,2型糖尿病患者胰岛Rb基因表达显著降低[6],其在胰岛细胞扩增中的作用正日益受到重视。本文就口袋蛋白家族在胰岛发育及稳态调控中的研究进展作一综述。
