Integrating DNA Methylation and Hydroxymethylation Data with the Mint Pipeline

Area of Science:

• Epigenetics
• Genomics
• Bioinformatics

Background:

• DNA methylation (5mC) and hydroxymethylation (5hmC) are key epigenetic marks regulating mammalian development, oncogenesis, and environmental responses.
• Current gold-standard sequencing methods cannot distinguish between 5mC and 5hmC, necessitating specialized analysis.
• Differentiating these marks is critical for accurate biological interpretation and cancer research.

Purpose of the Study:

• To develop a computational pipeline for comprehensive analysis of DNA methylation and hydroxymethylation data.
• To integrate data from bisulfite conversion and immunoprecipitation assays.
• To provide tools for visualization and interpretation of epigenetic modifications.

Main Methods:

• Development of the Methylation INTegration (mint) pipeline.
• Support for analyzing bisulfite conversion and immunoprecipitation-based assays.
• Implementation as both a command-line tool and a Galaxy graphical user interface.

Main Results:

• The mint pipeline enables comprehensive analysis of 5mC and 5hmC data.
• The tool facilitates integration, visualization, and interpretation of epigenetic data.
• Both command-line and GUI versions offer flexibility and require minimal configuration.

Conclusions:

• The mint pipeline effectively supports the analysis of distinct DNA methylation and hydroxymethylation marks.
• This tool aids researchers in differentiating and interpreting 5mC and 5hmC, advancing epigenetic studies.
• mint enhances the analysis of epigenetic data for applications in development, cancer, and environmental response research.
