negative regulatory element

Conclusions: Three key subelements, nt453-434, nt403-384 and nt283-264 sequence, were successfully identified in the negative regulatory element on hepatitis B virus.
結論:HBV nt453-434、nt403-384和nt283-264序列爲HBV nt250-453負性調節元件中發揮關鍵作用的三個亞元件;這三個亞元件可以獨立發揮作用;儅以協同的方式發揮作用時,則表現出最強的負性調節作用。
