摘要: 本研究旨在对猪THRSP基因5′调控区TP526序列进行转录调控活性的鉴定,以鉴别THRSP基因调控区的功能。提取猪耳组织基因组,利用PCR技术克隆THRSP基因5′调控区TP526序列,将其插入荧光素酶报告载体中(pGL3-Basic),构建猪THRSP基因5′调控区TP526序列调控的荧光素酶报告载体(pGL3-TP526 /promoter),经PCR鉴定后,转染293T细胞,利用双报告基因检测TP526序列的启动子活性。结果显示,pGL3-TP526 /promoter调控的表达载体,其萤火虫与海肾荧光素酶荧光强度之比(1.816 2±0.253 3)显著高于pGL3-Basic(0.126 7±0.020 3),呈高效表达(P<0.01)。THRSP基因5′调控区TP526序列具有启动子调控活性。

Abstract: The aims of this study were to identify TP526promoter activity of pigs THRSP gene and to understand functions of 5′ regulation region of THRSP gene. The DNA samples were extracted from pig ear tissue. The TP526promoter of thyroid hormon einducible nuclear protein Spot14 (THRSP) gene was amplified using PCR technology, inserted into the luciferase reporter vector (pGL3-basic) to construct pGL3-TP526/promoter. 293T cells were cotransfected with a plasmid containing the pGL3-TP526/promoter and pGL3-basic, respectively. The expression of luciferase gene in 293T cells was tested using the Dual-Luciferase Reporter Assay kit. The results showed that the fluorescence intensity ratio of firefly to sea pansy luciferase with (1.816 2±0.253 3) of pGL3-TP526/promoter was significant higher than that with (0.126 7±0.020 3) of pGL3-basic (P<0.01). It implied a significant promoter activity of TP526.
