Degradome Sequencing

Introduction and Workflow

  • Degradome sequencing, also called Parallel Analysis of RNA Ends (PARE), is a high-throughput technique to analyze RNA degradation products, uncovering RNA stability, miRNA targets, and regulatory networks.
  • Degradome Sequencing Workflow combines next-generation sequencing (NGS) with a modified 5' RACE method, involving RNA extraction, adapter ligation to capture degradation products, cDNA synthesis, and high-throughput sequencing to map RNA cleavage sites.
  • Bioinformatics analysis for Degradome Sequencing include data preprocessing, aligning reads to reference genomes, identifying miRNA/ta-siRNA cleavage sites, and quantifying cleaved targets, revealing RNA decay dynamics and regulatory mechanisms.
  • The method facilitates the discovery of novel miRNAs and ta-siRNAs, studies on miRNA-mediated gene regulation, and comparative RNA decay analysis across species, contributing to a comprehensive understanding of RNA life cycles.

Advantage

  • Degradome sequencing provides a focused analysis of RNA degradation, specifically targeting cleavage sites mediated by miRNAs and ta-siRNAs, making it ideal for studying gene regulation and RNA stability.
  • By targeting degradation products, degradome sequencing minimizes the impact of intact RNAs, enhancing sensitivity for detecting miRNA targets and cleavage events.
  • Degradome sequencing focuses on RNA cleavage sites, eliminating the need for additional steps like ribosomal RNA removal, making it a more cost-effective alternative to broader transcriptome studies.
  • Degradome sequencing enables the identification of novel regulatory elements, such as circRNAs and biomarkers, expanding its utility in understanding RNA regulatory networks.
