Great expectations - Epigenetics and the meandering path from bench to bedside

Area of Science:

• Biomedical Science
• Molecular Biology
• Genetics

Background:

• Epigenetics, the study of heritable gene function changes without altering DNA sequence, has gained prominence.
• The field has evolved from a conceptual framework to a mechanistic understanding, driven by molecular biology advancements.
• High expectations exist for epigenetics in understanding complex diseases and developing new therapies.

Purpose of the Study:

• To review the current state of epigenetics research.
• To discuss the challenges and potential of epigenetic medicines.
• To speculate on future contributions of epigenetics to prognosis and therapy.

Main Methods:

• Literature review of epigenetic phenomena, including DNA methylation and histone modifications.
• Analysis of the evolution of the term 'epigenetics' in scientific discourse.
• Discussion of the transition from basic science discoveries to clinical applications.

Main Results:

• Significant progress has been made in understanding epigenetic mechanisms.
• Despite numerous reports on DNA methylation and histone modifications, clinical applications of epigenetic medicines remain unclear.
• The translation of epigenetic discoveries into effective therapies faces considerable hurdles.

Conclusions:

• Epigenetics holds potential for understanding complex diseases and developing novel therapeutic strategies.
• Further research is needed to overcome the challenges in translating epigenetic findings into clinical practice.
• The future of epigenetics in medicine likely involves contributions to both prognostic tools and therapeutic interventions.
