摘要:

【目的】测定PFKM基因在伊犁马不同组织部位中的差异表达,为该基因在伊犁马的糖酵解过程中功能提供一定基础。【方法】以伊犁马为试验动物,分别提取心脏、肝脏、夹肌、斜方肌、背阔肌、臀中肌、半腱肌以及腹外斜肌8种组织的总RNA,以伊犁马不同组织的RNA为模板,逆转录合成cDNA,GAPDH为内参基因,运用荧光定量PCR的方法检测PFKM基因mRNA在伊犁马不同组织间的相对表达量。运用酶联免疫法(Elisa)检测伊犁马不同组织中糖酵解相关酶的含量。【结果】伊犁马PFKM基因在以上8种组织部位中都有表达,在心脏中相对表达量最高,肝脏中相对表达量最低,心脏中PFKM基因mRNA相对表达量极显著高于马匹其他部位(P<0.01)。马匹心脏组织中6-磷酸果糖激酶的活性显著高于其他部位。【结论】在糖酵解途径中,PFKM基因6-磷酸果糖激酶对心脏组织的糖酵解有重要的影响。

Abstract:

【Objective】 To determine the differential expression of PFKM gene in different tissue sites in Yili horses in the hope of providing some research basis to clarify the function of this gene during glycolysis in the horses. 【Methods】 Total RNA was extracted from the heart, liver, clip, trapezius, latissimus dorsi, gluteus medius, semitendinosus and external oblique of the abdomen of the Yili Horse, the relative expression of PFKM mRNA in different tissues was detected by real-time fluorescent quantitative PCR. And the cDNA was synthesized by reverse transcription using RNA from different tissues and GAPDH as internal reference gene. Enzyme-linked immunosorbent assay (Elisa) was used to determine the content of related enzymes in tissues. 【Results】 PFKM gene was expressed in all of the above 8 tissues, with the highest expression level in heart tissues and the lowest in liver tissues, the expression of PFKM gene mRNA in heart was significantly higher than that in other tissues (P< 0.01). Analysis of 6-phosphofructokinase activity in eight tissues of Yili Horses showed that 6-phosphofructokinase activity in heart tissue was significantly higher than that in other tissues, suggesting that in glycolytic process. 【Conclusion】 PFKM gene is involved in the regulation of glycolysis through the action of 6- PFK in the heart tissue, the results of which will lay a foundation for analyzing the effect of PFKM gene in glycolytic process.
