Background:

DNA methylation is a key epigenetic mechanism regulating gene expression.
Aberrant DNA methylation is implicated in various complex diseases, particularly cancer.

Purpose of the Study:

To review recent advances in understanding DNA methylation patterns in normal and tumor states.
To illustrate the potential roles of DNA methylation in cell development and canceration.

Main Methods:

Comparative analysis of DNA methylation profiles across different tissues and samples.
Review of studies on genomic locations of CpGs and their impact on gene expression.
Examination of pan-cancer and cancer-specific methylation patterns.

Main Results:

Common DNA methylation patterns are involved in fundamental cellular functions.
Cell type-specific methylation patterns are linked to cell identity and function.
Abnormal DNA methylation is central to tumor development, heterogeneity, and patient survival.

Conclusions:

DNA methylation patterns, both common and specific, play critical roles in normal cell development and disease.
Understanding these patterns offers insights into cancer mechanisms and potential therapeutic targets.
