Profiling the epigenome using long-read sequencing

Area of Science:

• Genomics
• Transcriptomics
• Epigenomics

Background:

• Single-molecule, long-read sequencing (LRS) technologies from Oxford Nanopore and Pacific Biosciences have transformed biological research.
• LRS offers direct detection of DNA modifications (e.g., methylation) and analysis of kilobase-spanning DNA sequences at the single-molecule level.

Purpose of the Study:

• To review LRS-based experimental and computational strategies for characterizing chromatin states.
• To highlight the advantages of LRS over short-read sequencing methods.
• To demonstrate the integration of LRS methods for multi-omics studies investigating chromatin states and transcriptional dynamics.

Main Methods:

• Discussion of LRS technologies and their applications in epigenomics.
• Comparison of LRS with short-read sequencing approaches.
• Integration strategies for multi-omics data using LRS.

Main Results:

• LRS facilitates comprehensive epigenomic profiling by integrating DNA methylation, chromatin accessibility, transcription factor binding, and histone modification data.
• LRS enables the detection of alternative, nascent, and translating transcripts.
• LRS provides a powerful tool for analyzing chromatin states and their relationship with transcriptional dynamics.

Conclusions:

• LRS technologies offer significant advantages for epigenomic research and transcriptomics.
• Integrated LRS-based multi-omics studies are crucial for a holistic understanding of gene regulation and cellular function.
