Study Notes
Definition
- Epigenetic biomarkers: molecular markers that detect epigenetic changes, such as DNA methylation, histone modifications, or chromatin remodeling, associated with specific diseases or conditions.
Types of Epigenetic Biomarkers
- DNA methylation biomarkers: detect changes in DNA methylation patterns, often used in cancer diagnosis and prognosis.
- Histone modification biomarkers: detect changes in histone post-translational modifications, such as acetylation or methylation.
- Chromatin remodeling biomarkers: detect changes in chromatin structure and organization.
Applications of Epigenetic Biomarkers
- Cancer diagnosis and prognosis: detect tumor-specific epigenetic changes for early detection and monitoring.
- Neurological disorders: detect epigenetic changes associated with neurological diseases, such as Alzheimer's or Parkinson's.
- Developmental disorders: detect epigenetic changes associated with developmental disorders, such as Rett syndrome.
- Prenatal testing: detect epigenetic changes associated with fetal development and growth.
Advantages of Epigenetic Biomarkers
- Non-invasive: can be detected in bodily fluids, such as blood, urine, or saliva.
- Sensitive and specific: can detect specific epigenetic changes associated with diseases.
- Early detection: can detect epigenetic changes before symptoms appear.
Challenges and Limitations
- Standardization: lack of standardization in epigenetic biomarker detection methods.
- Interpretation: complexities in interpreting epigenetic data and correlating with disease states.
- Validation: need for large-scale validation studies to establish clinical utility.
