组学检测

 诺敏科达组学检测涵盖非靶向代谢组学(Untargeted metabolomics)、广靶代谢组学以及转录组学三大检测。

 

1.代谢组学介绍

代谢组学(metabolomics)是继基因组学和蛋白质组学之后新近发展起来的一门学科,是系统生物学的重要组成部分,其研究对象大都是相对分子质量在1500 Da以内的小分子物质。

非靶向代谢组学是指无偏向性地对样本中提取到的所有代谢物进行检测分析,通常可以对生物体内各类代谢物进行大规模、系统性地定性定量分析,从而最大程度反映生物体内代谢物的变化情况,适合前期基础研究或初步探索。

广靶代谢组结合靶向代谢组定量准的优势建立的代谢组检测技术,针对目标明确的一种或几种途径的代谢产物,利用质谱的选择能力和灵敏度,结合个性化的样品预处理方法(制备和色谱)进行检测,适用于特定关注的代谢物检测分析或者对非靶代谢组筛选到的差异代谢物进行验证。

采用超高效液相色谱-串联静电场轨道阱质谱联用仪(UHPLC-Q Exactive HFX,Thermo,USA)对样本中的代谢物进行检测。通过与本地数据库及商业数据库中代谢物的保留时间、分子质量(分子质量误差在10 ppm内)[5]及二级碎裂谱图等信息进行匹配,对生物样本中的代谢物进行定性定量及后续的生物信息学分析。

2.转录组学介绍

转录组,广义上指某一生理条件下,细胞内所有转录产物的集合,包括mRNA,rRNA,tRNA以及其他non coding RNA,狭义上指mRNA 集合,利用高通量测序技术,全面快速获取某一物种特定组织或器官在某一状态下的所有mRNA的序列信息。并对mRNA的结构和表达信息进行分析。

转录组测序信息分析流程主要分为三部分:测序数据质控、数据比对分析和转录组深层分析。其中,测序数据质控包括过滤测序所得序列、评估测序数据质量以及计算序列长度分布等;数据比对分析主要是针对比对到基因组中的序列,根据不同的基因组注释信息依次进行分类和特征分析,并计算相应的表达量;然后进行差异表达分析,常规转录组分析中还有可变剪接分析、新转录本预测和变异分析深层分析及其他个性化分析。具体的信息分析流程图如下:
