TL;DR

This paper introduces a new method using nanopore sequencing to study DNA methylation patterns related to aging, offering a more detailed and efficient approach than previous techniques.

Contribution

The novel framework utilizes nanopore sequencing to capture full CpG context and study epigenetic aging without bisulfite conversion.

Findings

Nanopore sequencing captures full CpG context and diverse genomic regions for age-associated methylation profiling.

The method removes bisulfite conversion steps and is compatible with the latest reference genome.

Nanopore sequencing is established as a powerful tool for epigenetic aging research and anti-aging interventions.

Abstract

Background/Objectives: Advances in nanopore sequencing have opened new avenues for studying DNA methylation at single-base resolution, yet their application in epigenetic ageing research remains underdeveloped. Methods: We present a novel framework that leverages the unique capabilities of nanopore sequencing to profile and interpret age-associated methylation patterns in native DNA. Results: Unlike conventional array-based approaches, long reads sequencing captures full CpG context, accommodates diverse and repetitive genomic regions, removes bisulfite conversion steps, and is compatible to the latest reference genome. Conclusions: This work establishes nanopore sequencing as a powerful tool for next-generation epigenetic ageing studies, offering a scalable and biologically rich platform for anti-ageing interventions monitoring and longitudinal ageing studies.
