Epigenome editing or Epigenome engineering is a type of genetic engineering in which the epigenome is modified at specific sites using engineered molecules targeted to those sites (as opposed to whole-genome modifications). Whereas gene editing involves changing the actual DNA sequence itself, epigenetic editing involves modifying and presenting DNA sequences to proteins and other DNA binding factors that influence DNA function. By "editing” epigenomic features in this manner, researchers can determine the exact biological role of an epigenetic modification at the site in question.

  • エピゲノム編集(Epigenome editing, epigenome engineering)は、遺伝子工学の一手法であり、クロマチンやエピゲノム修飾を選択的に改変する手法である。ゲノム編集が特定のDNA配列そのものを改変するのに対して、エピゲノム編集では目的DNA配列の機能に関係する周辺のDNA修飾やヒストン修飾などを改変する。この手法によって、特定のクロマチンやエピゲノム修飾がゲノムや細胞の機能に与える影響を調べることができ、また遺伝子治療の一形態として病気の治療へ応用することも検討されている。 エピゲノム編集に使用される人工タンパク質は、特定の配列を標的とするDNA結合ドメインと、エピゲノム修飾を変更する機能ドメインで構成される。DNA結合ドメインとしては、ゲノム編集でも用いられるジンクフィンガー、 (TALEs)、および Clustered Regularly Interspaced Short Palindromic Repeats /CRISPR associated protein (CRISPR/Cas) システムが用いられる。 (ja)

  • Epigenome editing or Epigenome engineering is a type of genetic engineering in which the epigenome is modified at specific sites using engineered molecules targeted to those sites (as opposed to whole-genome modifications). Whereas gene editing involves changing the actual DNA sequence itself, epigenetic editing involves modifying and presenting DNA sequences to proteins and other DNA binding factors that influence DNA function. By "editing” epigenomic features in this manner, researchers can determine the exact biological role of an epigenetic modification at the site in question. The engineered proteins used for epigenome editing are composed of a DNA binding domain that target specific sequences and an effector domain that modifies epigenomic features. Currently, three major groups of DNA binding proteins have been predominantly used for epigenome editing: Zinc finger proteins, Transcription Activator-Like Effectors (TALEs) and nuclease deficient Cas9 fusions (CRISPR).
