Genome Science
Epigenetics & Chromatin
DNA methylation, histone modification and regulatory memory across tissues.
Scientific context
Understanding the field
Research examines how epigenetic states are established, maintained and disrupted, including imprinting disorders and episignature-based diagnostics.
Epigenetics studies molecular states that influence genome activity without changing the DNA sequence. DNA methylation, histone modifications and chromatin accessibility vary across cell types, development and environmental contexts.
Central questions
- How are regulatory states established and maintained?
- Which epigenetic changes are cause, consequence or biomarker?
Methodological framework
- Bisulfite sequencing and methylation arrays
- Chromatin accessibility and histone profiling
- Single-cell and longitudinal epigenomics
Relevance
Scientific and clinical value
Epigenomic patterns can reveal cell identity, developmental regulation and disease-associated signatures, including carefully validated episignatures in selected diagnostic contexts.
Limits and responsibility
Epigenetic measurements are tissue-, time- and exposure-sensitive. Observational differences do not prove inheritance or causality, and commercial claims require evidence beyond correlation.
