NQO1抑制劑Dicoumarol調(diào)控HBx穩(wěn)定性對乙肝病毒轉(zhuǎn)錄復(fù)制的重要作用
發(fā)布時間:2021-08-11 06:36
目的1.明確NQO1抑制劑DIC對HBV轉(zhuǎn)錄復(fù)制的調(diào)控作用。2.解析NQO1調(diào)控HBx蛋白穩(wěn)定性的分子機(jī)制。3.闡明NQO1穩(wěn)定HBx蛋白對ccc DNA轉(zhuǎn)錄和HBV復(fù)制過程的重要作用。4.探究NQO1/HBx調(diào)控ccc DNA轉(zhuǎn)錄的分子機(jī)制。5.體內(nèi)實(shí)驗(yàn)充分評估NQO1抑制劑DIC的抗HBV效能。方法1.利用Nano-Glo?Hi Bi T Lytic Detection System評估NQO1抑制劑DIC對病毒蛋白HBx表達(dá)水平的調(diào)控作用;Western blot檢測DIC對外源性和內(nèi)源性HBx蛋白水平的影響。2.在HBV感染的Hep G2-NTCP中,使用不同濃度的DIC處理細(xì)胞:real-time PCR(RT-PCR)檢測total HBV RNAs和pg RNA的水平;Northern blot檢測HBV 3.5-kb和2.1/2.4-kb RNA水平;Quantitative real-time PCR(q RT-PCR)檢測HBV ccc DNA水平。3.在Hep G2細(xì)胞中敲減/敲除或過表達(dá)NQO1,共轉(zhuǎn)染HBx:Western blot和RT-PCR檢測HBx蛋白...
