ポリソーム プロフィール分析と、特定の mRNA の全体のトランスクリプトーム6,7並進状態の分析によりタンパク質翻訳の研究。ローカル翻訳シナプトソーム8など検討する必要がある場合、それは大きな助けとだも。伝統的に、この方法は、モノとポリゾームとショ糖密度勾配をゲノムと結合することができるまたは目的の結果<sup c...

中心部は、(I) 虚血と再灌流 (R) ダイナミックなファッションでの傷害に応答します。ただし、応答の中にタンパク質合成に急性の変化に少し洞察力があります。これに対処するため行ったリボゾームとポリソーム、細胞質から並進規制要因の再分配を反映したタンパク質豊富に変更を識別するために1をプロファイリング ポリソームの確立方法の利点と新しく合成されたタンパク質 (Nsp) の増加します。私の設定で/R、新しい Mrna2; の転写と一貫性がないタイム フレームでの蛋白合成の増加が発生しますまた、mRNA 発現および蛋白質量の不一致は、報告された3をされています。これらの理由から、タンパク質翻訳を反映して動的プロテオームの変化を分析することを選びました。これを行うには、我々 はポリソーム分数の mRNA を定量化し、ポリソーム分数のタンパク質組成を分析します。最後に、マイクロ Rna (miRs) Mrna の翻訳の可用性を調節するタンパク質翻訳4、5の効率を妨げることができますので、我々 の分布を調べた miRs ポリソーム画に焦点を当て、私への応答/r.
マウス単離蛍光灌流モデルと持続灌流、30 分虚血流入なしと虚血後再灌流の 30 分, 30 分後の基底条件下で収穫された組織を使用決定しました。心臓組織を可溶化し、ショ糖密度勾配をポリソームを区切ってそれぞれプロテオーム解析と Mrna と PCR、マイクロ アレイ、miRNAs の選択的検出が続きます。このメソッドの組み合わせを表す NSPs、マイクロ Rna、mRNA の同時検出だけでなく、nontranslating の分数の間調節タンパク質、マイクロ Rna、mRNA の再配布を有効にするプロテオームを理解するための強力なアプローチ低効率ポリソームと高効率ポリソーム (図 1参照)。この過程の動的調節への洞察力は、神経: Eif2 など mTOR 因子のリン酸化の詳細な分析によって拡張されます。これらの個々 のステップは、今詳細に説明します。

dynamic proteomic and mirna analysis of polysomes from isolated mouse heart after langendorff perfusion

タンパク質翻訳のダイナミックな変化の研究では、特殊なメソッドを必要とします。ここで虚血と再灌流ポリソームのプロファイリングと相まって分離灌流マウスの心臓を使用する新規合成される蛋白質の変化を調べた。タンパク質翻訳のダイナミックな変化をさらに理解する私たちは (ポリゾームまたはポリソーム) ゾル性細胞質のリボソームで読み込まれたともミトコンドリア ポリソームを回復し、mRNA とタンパク質の分布を比較して Mrna を特徴と、高効率分数 (多数リボソームが mRNA に付着)、低効率 (少ないリボソームが付着) ミトコンドリア ポリソームと非翻訳分画も含まれています。Mirna が翻訳されているが, 翻訳の効率を減らす Mrna に関連付けることも、分数の miRNAs の分布を調べた。グローバル ・虚血、再灌流の 30 分後と 30 分の終わりに、基底の灌流条件下で Mrna、Mirna、および蛋白質の分布を調べた。この分析を達成するために使用されるメソッドの紹介-特に、これとしてショ糖密度勾配からの蛋白質の抽出の最適化へのアプローチはないの前に記載されている-いくつかの代表的な結果を提供して。

mRNA の解析 mRNA の結果は、各画分 (図 3 a); 特定の mRNA の分布として表現できます。定量化, polyribosomal 翻訳分数を結合および非翻訳分数 (図 3 b)、nontranslating の分数に変換する mRNA の豊かさの割合を提示に比較します。追加情報は、高効率ポリソーム分数低効率ポリソーム分数を個別に (または nontranslating 分数とは別...
