摘要:

为了进一步理解Fas/FasL 系统,本研究拟克隆牦牛FasFasL基因,并对2个基因在各组织器官中的表达进行检测。采用RT-PCR方法克隆牦牛FasFasL基因,并利用相关软件进行生物信息学分析,结合RT-PCR方法及免疫组织化学方法对2个基因在牦牛主要组织器官中的表达进行检测。克隆得到了2 605 bp的牦牛Fas基因 cDNA和1 572 bp 的FasL基因 cDNA序列,与黄牛的相应序列有很高的同源性(分别为99.1%和99.4%)。除了在心中只检测到Fas mRNA外,FasFasL mRNA共同表达于所有检测的组织中,且2个基因均在肝、脾、肾、淋巴结、胸腺和睾丸中强表达。免疫组化检测发现FasL蛋白存在于多种体细胞的胞浆中。结果表明,除了在淋巴器官和免疫赦免位点外,FasFasL还强表达于其他器官如肾和肝,表明Fas/FasL系统比以前所了解的要复杂。

Abstract:

To further understand the function of Fas/ FasL system,the Fas and FasL genes of yak were cloned by RT-PCR method and their expressions were analyzed by combination of RT-PCR and immunohistochemistry.A complete cDNA sequences in 2 605 bp of Fas gene and 1 572 bp of FasL gene of yak was obtained.These sequences were highly homology with cattle.Fas and FasL mRNAs were co-expressed in all analyzed tissues except heart which expressed Fas mRNA alone.The two genes strongly co-expressed in liver,spleen,kidney,lymphonodus,thymus and testis.A cytoplasmic form of FasL protein was detected in several cell types of various organs.Fas and FasL were strongly co-expressed in lymphoid organs and immune privilege sites,they were also strongly co-expressed in other tissues like kidney and liver.The results suggested that Fas/FasL system was more complicated.
