摘要:

参考牦牛TLRs基因序列设计荧光定量PCR特异性引物,建立检测牦牛TLRs相对表达量的荧光定量PCR方法,分析TLR3TLR5基因在牦牛不同器官组织中的转录水平。结果显示两基因具有不同的表达谱及表达量,其中TLR3基因除在乳腺组织外,在其它组织器官中均有转录,其中在心、大肠、胃和肌肉组织中表达量较高;TLR5基因则在心、肺、大肠、小肠、胃、肌肉、卵巢组织中具有较高的表达量。该试验结果表明,TLRs在不同组织器官转录水平差异较大,可能与其对病原体的识别有关;同一个基因在不同组织中存在差异性,这可能与基因作用机理相关。

Abstract:

According to the sequences of yak TLR3 and TLR5, the real-time PCR primers were designed to establish a method for the detection of mRNA transcription of TLRs by Real-time quantitative PCR, and the transcription level of TLRs in different tissues of yak was analyzed. The results showed that two genes have different expression pattern and expression level in tissues. The TLR3 mRNA was detected in examined tissues except mammary gland, and it was expressed at a higher level in heart, large intestine, stomach and muscle. The TLR5 mRNA level was higher in heart, lung, large intestine, small intestine, stomach, muscle and ovary. The results indicated that there exists difference in the transcription level of TLRs in tissues, which may be associated with the recognition of pathogens. For the same gene, the mechanism of gene may bring difference in expression level in different tissues.
