Background:

• DNA methylation (5-methylcytosine, 5-mC) is a key epigenetic mark regulating gene expression in development and disease.
• Novel cytosine modifications, including 5-hydroxymethylcytosine (5-hmC), 5-formylcytosine (5-foC), and 5-carboxylcytosine (5-caC), have emerged with potential regulatory roles.
• Understanding these epigenetic marks is vital for identifying disease biomarkers and therapeutic targets.

Purpose of the Study:

• To review recent advancements in methods for the global detection and location analysis of 5-mC and its oxidation derivatives.
• To highlight the importance of studying these epigenetic modifications in the context of disease biology.
• To provide an overview of the current state of research on epigenetic mark discovery and characterization.

Main Methods:

• Focus on recent methodological developments for genome-wide analysis of DNA modifications.
• Discuss techniques enabling the discovery, detection, and precise localization of 5-mC and its oxidized forms.
• Review strategies for studying epigenetic marks in various biological contexts.

Main Results:

• Significant progress has been made in developing sensitive and accurate methods for detecting 5-mC and its derivatives.
• These methods allow for comprehensive mapping of epigenetic marks across the genome.
• The characterization of these marks provides insights into their roles in normal cellular function and disease pathogenesis.

Conclusions:

• Advanced detection and location methods are crucial for understanding the functional roles of 5-mC and its oxidation derivatives.
