MicroRNA Analysis Using Next-Generation Sequencing
Next-generation sequencing (NGS) enables the analysis of both microRNA expression and sequence, allowing for elucidation of a comprehensive landscape of miRNAs in a given tissue and sample type. NGS analysis requires high-quality RNA extraction and preparation of microRNA libraries. In this chapter, we describe the methods used for RNA extraction from tissue specimens, serum, cytological slides, and formalin-fixed paraffin-embedded samples. Although the described library preparation and sequencing approaches are based on Illumina NextSeq 500 sequencing technology, the presented principles shall be compatible with other commercially available sequencing platforms.
