启动

Complementary sense promoter from cotton leaf curl virusis a novel promo ter and could direct high level expression of foreign genes in transgenic plants .

摘 要 棉花曲叶病毒互补链基因启动子是一种新近鉴定的启动子，它能驱动外源基因在植物体内高效表达。

I had a job in Lexington, the place at that time was called The Community Kitchen.

我不知道其中的科学机理，真不知道，但我知道这与战斗理论有联系，当面临危险，它启动，当你感到受威胁，它启动。

Its function is limited launch services, launch a calculator.

它的功能有限只是启动服务的时候，启动一个计算器。

If you're willing to log in at the command line and start X manually, you can save yourself a lot of system resources -- and the time it takes to load them.

如果你喜欢在命令行界面登录然后手动启动X，你能节约很多系统资源和启动它们的时间。

The promoter activity of 13th and 26lh passages of EIAV_ LTR were higher than EIAV_ and EIAV_D LTRs in equine macrophages and fetal donkey dermal cells, and the promoter activity of EIAV_D LTR was the lowest.

第13、26代EIAV_ LTR的启动子活性在马巨噬细胞和驴胎皮肤细胞中显著高于EIAV_、EIAV_D LTR的启动子活性，EIAV_D LTR的活性最低。

Objective To establish dual luciferase report gene system basic the Y-box sequence of MDR1 gene and analysis it s activity.

目的 通过构建以MDR1启动子为启动序列的双荧光素酶报告基因系统并进行活性分析，为MDR1基因表达的单靶点调控研究和逆转剂的筛选提供一种有效的方法。

The transcriptional activities of survivin promoter in various cel1s were determined by detection of the expression of luciferase.

survivin启动子在前列腺癌细胞中具有较强启动活性，有可能成为新的前列腺癌靶向性基因治疗工具。

Methods:The luciferase reporter plasmids of MDM2 P2 promoter containing different SNP309 were contructed,and cotransfected into CV-1 cells with AML1-ETO,AML1 and SP1 expression plasmid.The transactivities of luciferase were assayed by luminometer to determine the impact of AML1,AML1-ETO,and SP1 on MDM2 P2 promoter.

研究方法：构建含不同SNP309位点的MDM2 P2启动子的报告质粒，与AML1-ETO、AML1以及SP1的表达质粒单独或共转染CV-1细胞，测定荧光素酶的活性，分析AML1-ETO、AML1以及SP1对MDM2 P2启动子的影响。

Next,we transfected the HOXD13 expression vector,luciferase reporter driven by EPHA7 promoter and renilla luciferase reporter into mouse C3H10T1/2 cell. Thirty six hours after transfection,relative luciferase activity was tested by luminometer.

结果显示，与野生型HOXD13蛋白相比，p.Q317R突变体对EPHA7启动子的转录激活作用明显降低，下降至野生型的13%，而p.1314L突变体对EPHA7启动子的转录激活作用也降低，但降低程度没有p.Q317R明显，为野生型的63%。

Therefore, with considering threshold pressure gradients and the maldistribution of threshold pressure gradients caused by reservoir heterogeneity, it will be more objective and better to forecast the production performance of gas wells and guide low-permeability gas reservoirs practical production.

因此，考虑启动压力梯度和由储层非均质性引起的启动压力梯度非均匀分布能更为客观的预测气井单井生产动态，为气田合理开发提供可靠的决策依据。

In the end, transportation of PAHs in the environmental matrix was preliminarily investigated and discussed according to PAHs data of soils and sediments from a certain region in Shanghai. The result indicated that there are two or more pathways on PAHs transportation in the environmental matrix.

最后，对上海特定地区内PAHs在环境介质中的迁移径途进行了分析讨论，结果表明上海市土壤和沉积物等环境介质中PAHs的迁移存在多种途径。
