摘要:

通过对蒙古马运动前后与运动相关基因表达量差异的研究,了解与蒙古马耐力相关的基因。采用荧光定量 PCR方法检测蒙古马臀中肌中与能量代谢和肌肉生长相关的7个基因的mRNA表达量在静止期(T0)10 000 m耐力运动刚刚结束(T1)及运动后恢复期(4 h后,T2)的变化;并对mRNA表达量差异显著的基因采用Western blotting 方法对其蛋白的表达进行研究。结果表明,与蒙古马静止期基因的mRNA表达量相比,10 000米的耐力运动4 h后有2个基因(PPARGC1APDK4)的mRNA表达显著上调(P0.05),Western blotting 结果也显示这2个基因的蛋白表达量在运动后发生了增加。以上结果初步揭示了,PPARGC1APDK42个与能量代谢相关的基因和蒙古马的运动关系密切,为深入研究蒙古马的运动提供了基础数据。

Abstract:

To understand the genes related to endurance of Mongolia horses, the differential expression of genes related to exercise before and after exercise was detected in this study. The expression changes of 7 genes related with energy metabolism and muscle growth were measured in Mongolian horses skeletal muscle at three stages (pre-exercise (T0), immediately post 10 000 m endurance exercise (T1) and 4 h post exercise (T2)) by using quantitative RT-PCR. And protein expression of the genes which mRNA expression levels were significantly different at the three stages were observed using Western blotting. The results showed that mRNA expression level of two genesPPARGC1A and PDK4increased significantly at T2 stage than that at T0 stage. Western blotting results also showed the protein expression of two genes after endurance sports had increased. These results reveal that the PPARGC1A and PDK4 are closely related to exercise. The above results provide some data for further study of the Mongolia horse exercise.

Key words: Mongolia horse, exercise, gene expression, energy metabolism
