摘要
目的探讨用于老年大鼠组织基因mRNA表达分析的内参基因选择。方法用实时反转录PCR技术评价5个管家基因3-磷酸甘油醛脱氢酶(G3pd)、β-肌动蛋白(ACTB)、H3组氨酸3B(H3f3b)、酸性核糖体磷蛋白P0(Arbp)和18S核糖体RNA(18S)的表达水平。结果老年大鼠肾组织中表达最稳定的是管家基因ACTB,心脏和肺组织中表达最稳定的是G3pd;而Arbp在不同组织之间的表达差异最小。结论老年大鼠组织间基因表达mRNA分析应使用至少两个参照基因:一个是核糖体基因18S,另一个适合的内参基因是Arbp。
Objective To investigate the proper inner control genes suitable for mRNA expression level comparison of aging rat tissues. Methods Real-time reverse transcription PCR was used to examine in aging rat tissues the expression level of G3pd ( glyceraldehyde-3-phosphate dehydrogenase ) , ACTB (β-actin ) , H3f3b ( H3 histone, family 3 B ) ,Arbp ( acidic ribosomal phosphoprotein P0 ) and 18S ( 18 S ribosomal RNA). Results The most stably expressed housekeeping gene in aging rat kidney was ACTB, in heart and lung G3pd showed the minimum variation; Arbp expression was the most stable one in different tissues. Conclusion For aging rat intra-tissue mRNA normalization at least two housekeeping genes should be used: one is the ribosomal RNA gene 18S and another one is Arbp.
