来自赫尔辛基大学的研究人员发现了一个全新的机制,通过这一机制,STAT3基因发生突变,直接导致胰腺发育障碍和婴儿糖尿病。基因突变使得负责控制胰高血糖素和血糖分泌的细胞过早分裂。

新生儿糖尿病(NDM)或者婴幼儿糖尿病是由于基因突变引起的一种罕见的糖尿病类型,大约半数的病患会发展成永久性疾病,其中引起疾病的20多种基因突变目前尚未确定。

与一型糖尿病不同的是,NDM没有与糖尿病相关的自体抗原,然而,最近发现,激活STAT3基因突变可能导致包含自身免疫现象的儿童糖尿病。

在最新的研究中,研究人员发现STAT3基因突变对胰腺发展的影响。在实验室进行的小鼠实验中,研究人员发现,STAT3基因突变会促进胰腺细胞早熟,使产生胰高血糖素和分泌胰岛素的细胞过早分裂。

研究人员表示:“我们发现STAT3基因突变机制是早发性糖尿病的根源,即使这种基因突变并不常见,这项研究仍具有广泛的影响,接下来,我们将使用新的干细胞技术和基因组编辑方法,高精度分析潜在疾病突变的机制,希望在不远的将来,我们可以用相同的方法来研究其他类型的糖尿病,把这一困扰全球的疾病扼杀在摇篮里。”
