中文摘要:
      目的:构建大鼠过氧化物酶体增生因子激活受体γ(peroxisome proliferator-activated receptor gamma)基因慢病毒表达载体, 获得可供转染的滴度,为进一步研究该基因在肝星状细胞活化(Hepatic stellate cells, HSC)及肝纤维化中的作用机制提供物质基 础。方法:大鼠PPAR-γ 基因序列进行PCR 扩增,与经AgeI 酶切后的pGC-FU-3FLAG 载体连接产生慢病毒载体表达质粒 pGC-fu-3flag-PPARG,转化DH5α,PCR 筛选阳性克隆,测序并转入293T 细胞Western blot 鉴定,而后将pGC-fu-3flag-PPARG, pHelper 1.0,pHelper 2.0 三质粒共转染293T 细胞,包装成慢病毒,收集上清浓缩病毒测定病毒滴度。结果:DNA 测序及Western blot鉴定证实构建的大鼠PPAR-γ基因慢病毒表达载体pGC-fu-3flag-PPARG正确,浓缩慢病毒悬液的滴度为2×108TU /ml。结 论:成功构建携带大鼠PPAR-γ 基因的重组慢病毒表达载体。
英文摘要:
      Objective: To construction of recombinant lentiviral expression vector carrying rat peroxisome proliferator-activated receptor gamma (PPAR-γ)gene, and to obtain the titer of the lentiviral stock for investigating the mechanism of PPAR-γexpression in the activation of HSC cells and hepatic fibrosis. Methods:Rat PPAR-γencoding sequence was amplified, then was ligated with pGC-FU-3FLAG lentivirol vector to construct the lentiviral expression vector named pGC-fu-3flag- PPARG. It was identified by PCR, DNA sequencing and Western blot . Virus packaging cells (293T cells) were co-transfected with lentivirol vector pGC-fu-3flag- PPARG, pHelper 1.0 and Helper 2.0 to construct lentiviral. The titers of recombinant viruses were determined by Real time qPCR. Results: Lentiviral expression vector of rat PPAR-γgene proved by sequencing and Western blot was successfully constructed. The titer of recombinant viruses was 2 ×108TU /ml. Conclusion:Rat PPAR-γlentiviral expression vector was constructed successfully.
