Exploring Epigenetic Ageing Using Direct Methylome Sequencing.

Area of Science:

• Genomics
• Epigenetics
• Bioinformatics

Background:

• Nanopore sequencing advances enable single-base resolution DNA methylation studies.
• Epigenetic ageing research has not fully utilized nanopore sequencing capabilities.

Purpose of the Study:

• To present a novel framework for profiling and interpreting age-associated DNA methylation patterns using nanopore sequencing.
• To establish nanopore sequencing as a tool for next-generation epigenetic ageing research.

Main Methods:

• Utilizing nanopore sequencing for native DNA methylation profiling.
• Developing a framework to interpret age-associated methylation patterns.

Main Results:

• Long-read sequencing captures full CpG context and repetitive genomic regions.
• Eliminates the need for bisulfite conversion, unlike array-based methods.
• Compatible with the latest reference genomes, offering enhanced accuracy.

Conclusions:

• Nanopore sequencing is a powerful tool for epigenetic ageing studies.
• Provides a scalable and biologically rich platform for monitoring anti-ageing interventions.
• Supports longitudinal ageing studies with comprehensive data.
