摘要:

为了构建合作猪HMOX1基因过表达载体,并分析其组织表达特征,本研究通过PCR扩增获取合作猪HMOX1基因完整CDS区序列,将其插入到pcDNA3.1(+)过表达载体中,构建pcDNA3.1-HMOX1过表达载体;并通过实时荧光定量PCR检测HMOX1基因在合作猪心、肝、脾、肺、肾、胃、十二指肠和背最长肌中的表达情况。结果显示,成功扩增出合作猪HMOX1基因924 bp的完整CDS区,通过双酶切和测序鉴定,HMOX1基因成功连接到pcDNA3.1(+)过表达载体中。组织表达结果显示,HMOX1基因在合作猪组织中表达量最高是脾脏,显著高于其它组织(P<0.05),其次是肝脏、肺脏、肾脏和心脏,在十二指肠中的表达量最低。研究结果为进一步研究HMOX1基因在合作猪高海拔低氧适应过程中的功能提供了重要参考。

Abstract:

In order to construct an overexpression vector of HMOX1 gene in Hezuo pigs and analyze its tissue expression characteristics, the complete CDS region sequences of HMOX1 gene were obtained by PCR amplification, and then were inserted into pcDNA3.1 (+) blank vector to construct pcDNA3.1-HMOX1 overexpression vector. At the same time, the expression of HMOX1 gene in the heart, liver, spleen, lung, kidney, stomach, duodenum and longissimus dorsi muscle of Hezuo pigs were detected by real-time quantitative PCR. The results showed that the completed CDS region of 924 bp of HMOX1 gene was successfully amplified and identified by double enzyme digestion and sequencing, which was successfully linked to the pcDNA3.1(+) overexpression vector. Results of tissue expression analysis showed that HMOX1 gene expression was the highest in Hezuo pig spleen tissue, followed by liver, lung, kidney and heart, and the lowest was in duodenum. These results can provide reference for further research on the function of HMOX1 gene in the process of adaptation of Hezuo pigs to high altitude and hypoxia.
