摘要: 目的 检测幼年与成年裸鼹鼠肺脏、肝脏和脑组织中低氧相关基因的表达水平, 分析裸鼹鼠耐低氧的分子机制。方法 分别提取幼年与成年裸鼹鼠肺脏、肝脏和脑组织中mRNA,采用RT-PCR方法检测低氧相关HIF-1α、VEGFb、FLT-1、FLT-3、Fiz1、NKRF基因的表达。结果 成年裸鼹鼠肺脏、肝脏和脑组织中HIF-1α、VEGFb、FLT-1、FLT-3、Fiz1、NKRF的表达水平显著高于幼年裸鼹鼠。结论 裸鼹鼠体内低氧相关基因在不同年龄阶段表达水平不同。

Abstract: Objective To detect the expression level of hypoxia related gene in lung, liver and brain of juvenile and adult naked mole rats to analyze the molecular mechanism of its resistance to hypoxia. Methods Total mRNA of the lung ,liver and brain of juvenile and adult naked mole rats were extracted respectively and then the expression of hypoxia related genes HIF-1alpha, VEGFb, FLT-1, FLT-3, Fiz1, NKRF were detected by RT-PCR. Results The expression level of HIF-1 alpha、VEGFb、FLT-1、FLT-3、Fiz1、NKRF in lung, liver and brain of adult naked mole rats was significantly higher than that of juvenile naked mole rats. Conclusion The expression level of hypoxia related genes are diferent in the naked mole rats of different ages.
