The present invention relates to methods and pharmaceutical compositions useful for the treatment of hyperglycemia. Thorough multiple analyses, inventors demonstrated that Gfi1 is expressed in pancreatic acinar cells, starting from the first stages of pancreatic embryonic development. Furthermore, they observed that Gfi1 mRNA levels remain steady throughout embryonic development, while they significantly increase during the first days of life. They challenged conditional mutant mice with high fat diet for 5 months and monitored their weight and glycemia weekly. All the animals displayed a rapid increase in body mass as expected. While control mice rapidly developed a massive hyperglycemia, mutant mice remained normoglycemic throughout the entire experiment. A similar protection from induced diabetes was observed upon treatment with a high dose of Streptozotocin. Accordingly, the present invention relates to a method of treating hyperglycemia in a subject in need thereof comprising administering to the subject a therapeutically effective amount of an inhibitor of Gfi1.
本发明涉及治疗高血糖的方法和药物组合物。通过多种分析,发明者证明,从胰腺胚胎发育的最初阶段开始,Gfi1 就在胰腺尖突细胞中表达。此外,他们还观察到,Gfi1 mRNA 水平在整个胚胎发育过程中保持稳定,而在生命的最初几天则显著增加。他们对条件突变小鼠进行了为期5个月的高脂饮食挑战,并每周监测它们的体重和血糖。所有动物的体重都如预期般迅速增加。对照组小鼠迅速出现大量高血糖,而突变体小鼠在整个实验过程中血糖保持正常。在使用大剂量链脲佐菌素治疗时,也观察到了类似的保护作用,使其免于诱发糖尿病。因此,本发明涉及一种治疗有需要的受试者高血糖症的方法,包括向受试者施用治疗有效量的 Gfi1 抑制剂。
