•        核仁小RNA (snoRNA)是一类中等长度的非编码小RNA，其长度60-400nt不等，与核仁核糖核蛋白结合形成snoRNPs复合物发挥功能[1]。在脊椎动物中，核仁小RNA的编码基因主要存在于蛋白编码基因的内含子区，经转录加工处理形成成熟的核仁小RNA分子[2]。snoRNA参与多种生物学过程，比如rRNA的加工处理，RNA剪接和翻译，以及氧化应激反应的调控[3]。snoRNA主要通过snoRNPs复合物来发挥作用。通过snoRNA碱基互补识别靶基因特定位点，snoRNPs复合物催化这些位点的2’-O甲基化或假尿嘧啶化反应。根据snoRNA结构与功能的不同，可以将snoRNA分为两大类：负责2’-O甲基化的box C/D snoRNA和负责假尿嘧啶化的box H/ACA snoRNA [1]。另外，还存在一类比较特殊的snoRNA- scaRNAs (它们具有类似box C、box D或者box H、box ACA结构，特异表达于small Cajal body) [4]。snoRNA可以产生更小片段的非编码RNA-sdRNA。sdRNA与miRNA类似，能够通过调节mRNA的稳定性来发挥作用 [5]。

         多项研究表明，snoRNA在肿瘤中异常表达，并在肿瘤的转移过程中扮演着重要角色 [6-7]。在乳腺癌和前列腺癌中，SNORD50A发生了2个碱基的缺失突变，并且其拷贝数明显降低，因此被认为是抑癌基因[8]。有趣的是，H/ACA box snoRNA SNORA42在肺癌中作为癌基因存在，抑制SNORA42的表达具有明显的抗癌作[10]用。C/D box snoRNAs的表达水平常伴随肿瘤的发生而增加 [11]。有一些C/D box snoRNAs可以作为疾病的分子标志物，比如SNORD44和SNORD43与乳腺癌的不良预后相关[9]。snoRNA在神经退行性疾病的发生发展过程也发挥着关键作用。snoRNAs在血液、痰液以及尿液中稳定存在，使其作为疾病分子诊断标志物方面具有巨大的前景。目前，snoRNA已经成为疾病领域特别是癌症领域里的研究热点。
         nrStar™ Human snoRNA PCR芯片包括359条snoRNA、7条snoRNA靶向snRNA以及4条snoRNP复合物成员mRNA，而nrStar™ Mouse snoRNA PCR芯片分别包含370个snoRNA。该PCR芯片覆盖了所有PCR技术可区分的snoRNA，能够快速方便的检测出组织、细胞以及血液中的snoRNA的表达情况。它还可应用于疾病分子标志物的高通量筛选和验证。
         为了确保数据质量，nrStar™ Human snoRNA PCR芯片包含3个针对人snoRNA的内参基因和2个针对人snoRNP复合物成员mRNA的内参基因，而nrStar™ Mouse snoRNA PCR芯片包含8个针对小鼠snoRNA的内参基因用于数据的均一化处理。此芯片还使用RNA Spike-in，PCC和GDC对照组来检测cDNA合成效率，PCR扩增效率和基因组DNA污染。

         为保证nrStar™ snoRNA PCR Array（H/M）的实验效果，建议配套使用Arraystar rtStar™ First-Strand cDNA Synthesis Kit (AS-FS-001) 。
