On correlative and causal links of replicative epimutations

Area of Science:

• Epigenetics
• Molecular Biology
• Genetics

Background:

• DNA methylation is a key epigenetic marker in eukaryotes, inherited through mitotic cell division.
• The relationship between the DNA methylome and cell division is bidirectional and complex.
• Epigenetic modifiers significantly influence DNA methylation patterns during replication.

Purpose of the Study:

• To review the principles and complexity of mitotic DNA methylation transmission.
• To emphasize the role of mitotic aging in DNA methylation dynamics.
• To discuss the implications of DNA methylation changes in development and disease.

Main Methods:

• Literature review of established principles and recent findings.
• Analysis of the interplay between DNA methylation and mitotic proliferation.
• Synthesis of evidence linking replicative epimutation to various health conditions.

Main Results:

• DNA methylation dynamics are shaped by epigenetic writers, erasers, and modulators.
• Altered DNA methylation impacts mitotic proliferation capacity, contributing to age-related diseases.
• Replicative epimutation is linked to stem cell dysfunction, inflammation, cancer, and epigenetic clocks.

Conclusions:

• DNA methylation plays a causative role in both health and disease.
• Understanding mitotic DNA methylation inheritance is critical for analyzing developmental and disease processes.
• Mitotic aging and DNA methylation dynamics are intertwined, with significant health implications.
