Abstract

The selection of proper reference genes and materials is critical in the design of PCR experiments, especially for differential expression studies. In this study, we propose a method to identify robust endogenous control miRNAs in the visceral adipose tissue of C57BL/6J mice with non-alcoholic fatty liver disease induced by alternating Western and control diets. This study outlines a comprehensive methodology for the analysis of microRNA endogenous controls using microfluidic cards in conjunction with miRNA profiling through small RNA sequencing and subsequent validation by quantitative PCR and the RefFinder algorithm. Criteria included were fold change, p-value, reads per million, and gene stability assessment. A set of six putative endogenous microRNAs was identified (miR-331-3p, let-7a-5p, miR-1839-5p, miR-151a-5p, let-7d-5p, and let-7c-5p). Subsequent validation and analysis using the RefFinder algorithm assessed the stability of the selected genes, and a combination of the three most stable endogenous miRNA controls (miR-331-3p, let-7a- 5p, and miR-1839-5p) exhibiting consistent expression patterns with minimal variability was set. Given the absence of universal endogenous controls, individual evaluation of normalizers for each experiment is imperative for accurate miRNA expression measurements. This approach, which combines multiple techniques and assessments, provides a reliable strategy for identifying and validating endogenous controls in miRNA studies.

期刊介绍: The Journal of Biosciences is a quarterly journal published by the Indian Academy of Sciences, Bangalore. It covers all areas of Biology and is the premier journal in the country within its scope. It is indexed in Current Contents and other standard Biological and Medical databases. The Journal of Biosciences began in 1934 as the Proceedings of the Indian Academy of Sciences (Section B). This continued until 1978 when it was split into three parts : Proceedings-Animal Sciences, Proceedings-Plant Sciences and Proceedings-Experimental Biology. Proceedings-Experimental Biology was renamed Journal of Biosciences in 1979; and in 1991, Proceedings-Animal Sciences and Proceedings-Plant Sciences merged with it.
