Overview Service Process Examples and Solutions Applications Frequently Asked Questions

Overview

Epigenome editing involves the use of engineered proteins, such as dCas9 (dead Cas9) fused with epigenetic modifiers, to target specific genomic loci and modify their epigenetic states. Unlike traditional gene editing, which changes the DNA sequence, epigenome editing modulates gene activity through reversible and heritable changes in chromatin structure. This approach is invaluable for studying gene regulation, modeling diseases, and developing new therapeutic strategies.

Service Process

The process of epigenome editing involves several critical and interrelated steps:

Target Identification: Selecting the specific genomic loci for epigenetic modification based on the research objective or therapeutic goal. Accurate target identification is crucial for the success of the editing process.
Tool Design: Designing and constructing dCas9 or other epigenetic editing proteins fused with modifiers such as DNA methyltransferases, demethylases, histone acetyltransferases, or histone deacetylases.
Vector Construction: Cloning the epigenome editing constructs into appropriate vectors for delivery into the target cells. This step ensures efficient expression of the editing tools in the cells.
Delivery of Editing Components: Introducing the epigenome editing constructs into the target cells using methods such as electroporation, viral vectors, or lipid nanoparticles. Efficient delivery is vital for successful epigenome editing.
Selection and Expansion: Isolating and expanding the successfully edited cells. This selection process may involve the use of selectable markers or advanced sorting techniques to enrich the population of modified cells.
Validation: Confirming the presence and accuracy of the epigenetic modifications through sequencing, chromatin immunoprecipitation (ChIP), and functional assays. This step ensures that the edits are precise and that the cells exhibit the expected phenotypic changes.
