自然界中有一类名为转录因子的蛋白可调节(升高或者降低)基因的活性，该技术正是基于该机理。
The technique relies on a natural process by which the activity of genes is raised or lowered by proteins called transcription factors.
LPL活性调节的这种组织特异性主要是由于不同组织lpl基因转录速率不同所决定的。
The tissue-specific changes in LPL activity can be determined by the different rate of LPL gene transcription in different tissue.
具体地，本发明显示E2-EPF5活性的抑制降低VEGF以及其他在低氧应答中由转录因子HIF-1调节的蛋白质的产生。
In particular, inhibition of E2-EPF5 activity is shown to reduce the production VEGF, as well as other proteins regulated the transcription factor HIF-1, in response to hypoxia.
