摘要:

血液循环microRNAs 表达量的变化与各种疾病及组织损伤的相关性研究备受关注。但细胞的污染,RNA 提取和处理过程中的试验误差都会不同程度的影响microRNAs 定量分析的结果。各种校正策略的使用可以消除这些影响因素。就目前使用的不同校正策略的优缺点进行分析,便于研究者正确选择血液循环microRNAs 定量分析的校正方法,从而获得准确可靠的生物学意义上的变化。

Abstract:

In recent years, the researchs on assossication between the circulating microRNAs from blood and various disease or tissue damage have attracted much attention. However, the imprecision of microRNAs concentrations may be caused by cellular contamination or variance attributable to extract and process RNA. Several strategies have been proposed for normalising these causes. In this review we discuss the relative advantages and disadvantages of different normalisation strategies and instruct researchers to choose a valid normalisation strategy that will enable the measurement of biologically meaningful results.
