chromatin immunoprecipitation assay for tissue-specific genes using early-stage mouse embryos

クロマチン免疫沈降（ChIP）はタンパク質を識別するための強力なツールです：1-3生きた細胞のコンテキストで発生するクロマチンの相互作用。この手法は、広く一次組織で、組織培養細胞の中で利用し、より少ない程度にされています。特に開発の早い時間にげっ歯胚組織、チップのアプリケーションは、組織の限られた量と胚の細胞と組織型の不均一性によって複雑になる。ここでは、解離胎生8.5（E8.5）の胚を用いてChIPを行うための方法を提示する。クロマチンの相互作用：単一のE8.5胚からの断片化クロマチンは、コントロールおよび特定の蛋白質の調査のための調査員に十分な材料を可能にするfiveアリコート、するに分けることができます。 組織特異的遺伝子発現プログラムの仕様中にクロマチンの相互作用：我々は、タンパク質を文書化し始めるためにこのテクニックを利用してきた。すべての相互作用が発生するかどうかといった区別なく、クロマチンの相互作用、のサブセット、または単セルのタイプ（S）：結果は、タンパク質の検出であるため、胚の細胞型の不均一性は、必ずしもこの手法の適用を制限する。しかし、組織特異的遺伝子発現の開始時または、以下の組織特異的遺伝子の検査は、2つの理由で実現可能です。最初に、組織特異的因子の免疫沈降は、必ずしも要因が発現する細胞の種類からクロマチンを分離します。遺伝子の活性化に関連付けられている第二に、コアクチベーターとヒストンの免疫沈降を含む翻訳後修飾は、遺伝子と遺伝子がされているか、アクティブ化された細胞のタイプの遺伝子調節配列で発見されるべきである。テクニックは、ほとんどの組織特異的遺伝子の活性化のイベントの調査に適用可能であるべきである。 後述の例では、我々は、骨格筋特異的遺伝子のプロモーターにおける結合因子を調べるためにE8.5及びE9.5のマウス胚を利用した。体幹と四肢の骨格筋が形成する元となる前駆組織である体節は、、E8.5 - 9.5 4,5で存在している。 Myogeninは、骨格筋の分化6月9日に必要な調節因子である。データはmyogeninがE8.5とE9.5の胚においてそれ自身のプロモーターに関連付けられていることを示しています。 myogeninが唯一の開発6,10のこの段階で体節で表されているため、データはそれ自身のプロモーターとmyogeninの相互作用は既にE8.5胚における骨格筋の前駆細胞で発生したことを示している。
