Treatment of Complex Diseases

Epigenome editing offers a gentler approach to gene editing: it is a genetic engineering technology that modifies gene transcription by targeting the underlying causes of dysregulation while keeping the primary DNA sequence intact. The epigenome consists of chemical compounds and modifications (such as methyl groups or histone alterations) that regulate gene expression without altering the DNA sequence itself.

Unlike traditional gene editing techniques, which involve cutting DNA, epigenome editing provides precise control over gene expression through reversible changes, making it a safer alternative. Epigenetic processes primarily regulate gene expression at the transcription level, where DNA is copied into RNA.

Epigenetic mechanisms that regulate gene expression include:

• DNA Methylation: The addition of a methyl group to DNA, which can silence genes by blocking transcription factor binding.
• Histone Modification: Chemical changes to histone proteins (around which DNA wraps) that affect gene expression.
• RNA-Mediated Processes: Non-coding RNAs that regulate gene activity.

Key Applications of Epigenome Editing:

• Treatment of Complex Diseases: It is effective for conditions like cancer, neurological disorders, and metabolic syndromes, which are influenced by multiple genetic factors.
• Regenerative Medicine: Improves stem cell therapies by controlling cell differentiation and aiding tissue repair.
• Immune System Engineering: Enhances immune cell function for advanced cancer immunotherapies.
• Safe and Reversible Gene Therapies: Reduces the risk of permanent genetic changes, providing precise and controlled treatments.
