摘要: 选择合适的内参基因是利用实时荧光定量PCR准确分析基因相对表达量的先决条件。选择了奶牛乳腺研究中广泛使用的7个候选内参基因,包括GAPDH、ACTB、18S rRNA、RPS9、RPS15、UXT、MYC。奶牛以精粗比不同的2种日粮饲喂,并在产后16 d采集乳腺组织。利用qRT-PCR技术探讨了候选内参基因在围产奶牛乳腺组织中的表达情况,并利用geNorm程序对数据进行分析。结果发现,UXT和RPS9表达稳定,不受日粮精粗比的影响,因此,可作为围产期奶牛乳腺组织基因表达分析中相对合适的内参基因。

Abstract: Selection of appropriate reference genes for normalization of quantitative PCR data for genes of inter- est is critical for interpretation of results.Seven candidate reference genes including GAPDH,ACTB,18S rRNA, RPS9,RPS15,UXT and MYC were selected in this research.Cows were fed different forage to concentrate(F: C) ra- tio dietary and mammary biopsies were taken at 16 day postpartum.The mRNA expression levels of seven candidate reference genes in mammary tissue were detected by qRT- PCR.Gene copy number was determined using absolute quantification,and then the expression stability of these genes were analysed by geNorm software.These results sug- gested that UXT and RPS9 showed less variability between the cows and were unaffected by dietary F: C ratio and, therefore,could be used to normalize mRNA levels of mammary in periparturient cows.

Key words: Periparturient cows, Mammary gland, Reference gene, qRT- PCR, geNorm software
