斑马鱼葡萄糖激酶的调节
葡萄糖激酶(GCK)是一种在葡萄糖稳态维持中起关键作用的酶。GCK在胰腺β细胞中作为胰岛素分泌的葡萄糖传感器,并调节肝脏中的糖原合成。虽然这种酶是开发新的抗糖尿病药物的一个有希望的靶点,但目前还没有临床上有用的药物。在一项新的研究中,来自奥地利因斯布鲁克大学的研究人员使用斑马鱼模型来研究正常和糖尿病情况下GCK的功能和调节机制。在确认了gck同种异构体在斑马鱼的代谢组织中表达后,研究小组表明,gck在斑马鱼的胰岛细胞中是组成性的,在肝脏中是营养依赖性的,类似于在哺乳动物中所显示的情况。通过将斑马鱼报告系与pdx1突变型糖尿病模型相结合,研究人员发现病理条件下gck反应被解除调控,并证明gck激活可以改善pdx1突变体的高血糖。斑马鱼模型具有保守的GCK功能和调控,有助于发现调节GCK治疗糖尿病的新药。原始参考文献:Schmitner, N.等。Commun。生物学报7,1557 (2024)
