摘要: β-actin mRNA和18S rRNA因其在相同试验条件下的稳定表达,而被广泛用作内标基因来确定目的基因的表达量。试验分别使用这2种内标基因,用相对定量RT-O36d)十二指肠钠葡萄糖共转运载体1(Sodium glucose cotransporter 1,SGLT1)的发育规律进行了分析研究,比较不同内标基因对SGLT1 mRNA表达水平检测结果的影响,以确定两者在一致试验条件下表达的相似度。结果表明,分别以-βactinmRNA和18SrRNA作为内标,SGLT1 mRNA表达发育规律完全一致,均表现为2~30d不断升高,44d下降,58d回升;2d和44 d的SGLT1 mRNA丰度显著低于16d(P<0.05)和30d(P<0.05),58d的SGLT1 mRNA表达水平显著低于30d(P<0.05)。提示这2种管家基因均可以作为内标用于肉鸡肠道转运载体基因mRNA发育规律的相对定量研究。

Abstract: Beta-actin mRNA and 18S rRNA are widely employed as internal control genes,with the assumption that they are expressed constitutively to a similar degree under same experimental conditions.The objective of this study was to investigate the SGLT1(Sodium glucose cotransporter 1) mRNA ontogenetic expression in duodenum of broiler chicken(0-58 d) by a semi-quantitative RT-PCR,using beta-actin mRNA and 18S rRNA as internal standard respectively.In this study,we tested this assumption by assessment of the transcription of these two genes in chicken intestinal tissues using a semi-quantitative RT-PCR.The results indicate showed that the SGLT1 mRNA ontogenetic expression were consistent whether beta-actin mRNA or 18S rRNA was acted as internal control.The SGLT1 mRNA abundance in duodenum of chicken increased from day 2 to day 30,then started to decline from day 44,and increased again from day 58.The SGLT1 mRNA expression level on day 2 and day 44 were lower significantly than that on day 16(P<0.05) and day 30(P<0.05) respectively.And the SGLT1 mRNA abundance on day 58 was lower significantly than that on day 30(P<0.05).It suggested that both beta-actin mRNA and 18S rRNA could be used as internal standard for semi-quantitative analysis of transport carrier gene mRNA in intestinal ontogenesis of broiler chicken.
