摘要:

为研究猪CYP1A1基因表达变化对肺炎支原体感染的影响,探讨CYP1A1与过氧化物酶体增殖物激活受体-γ(PPAR-γ)在肺炎支原体感染炎性反应过程中的作用关系,通过基因克隆及真核表达载体构建,获得猪CYP1A1基因全长编码序列真核载体,借助细胞转染和抗性筛选技术获取稳定表达CYP1A1基因的猪肺泡巨噬细胞系,构建猪肺炎支原体细胞感染实验模型,分析炎症反应前后CYP1A1与PPAR-γ间的表达变化关系。结果显示:在肺炎支原体感染PAM细胞的炎性反应过程中,PPAR-γCYP1A1表达呈明显的正相关,并参与炎症调控,揭示猪肺炎支原体感染过程中CYP1A1基因可通过调控PPAR-γ发挥抑炎作用。

Abstract:

In order to study the effect of CYP1A1 expression change in Mycoplasma hyopneuminiae infection and to investigate the association betweenCYP1A1and peroxisome proliferator-activated receptors associated-γ (PPAR-γ),we obtained the full-length coding sequence of CYP1A1 by means of cloning and eukaryotic expression vector construction method,established PAMs cell lines that stably expressed CYP1A1 by method of cell-transfection and resistance screening techniques,constructed cell experimental model infection with Mycoplasma hyopneuminiae and analyzed the relationship of the expression level of PPAR-γ and CYP1A1.The results show that the expression level of PPAR-γ is positively correlated with CYP1A1 and is involved in the regulation of inflammation,which suggest that CYP1A1 may play a role in suppressing inflammation by regulating PPAR-γ.

Key words: pig, CYP1A1, PPAR-γ, mycoplasma pneumonia, inflammatory
