HMEJ donör plazmid yapımında en önemli adım vardır: (1) yüksek DNA bölünme verimlilik ve düşük arasındaki mesafeyi sgRNA kesme makinası ve kodonu, HMEJ donör (2) uygun inşası ile sgRNA yelpazesi. CRISPR/Cas9-aracılı bölünme (sgRNA hedef siteleri ve ~ 800 bp homoloji silah içeren) her iki transgene donör vektör Tarih ve hedeflenen genom verimli ve hassas hedeflenen entegrasyon için gerekli içinde vivo. Çakma HMEJ tabanlı yöntemi kullanma fare nesil en kritik adımlar şunlardır: (1) ...

Kesin, hedeflenen genom düzenleme kez klinik tedavi ve genetiği değiştirilmiş hayvan modelleri üretmek için gereklidir. Düzenleme, çinko parmak nükleaz (ZFN), gibi transkripsiyon harekete geçirmek gibi efektör enzimler (TALENs), verimli hedeflenen genom için çeşitli stratejiler geliştirmek için çok çaba yapılmış ve CRISPR/Cas9 sistemleri. Bu stratejiler hedeflenen DNA çift iplikli kırılmalara (DSB) genom oluşturmak ve homolog rekombinasyon (HR)1,2, microhomology-aracılı sonunda (MMEJ)3 katılma gibi içsel DNA onarım sistemleri yararlanmak , 4 , 5ve homolog bitiş transgenes1,9hedeflenen Tümleştirme ikna etmek için (NHEJ)6,7,8 katılmadan. İK tabanlı strateji şu anda en sık kullanılan düzenleme yaklaşımı, hücre hatlarında çok etkili, ama geç S/G2 aşamasında kısıtlı onun oluşumu nedeniyle olmayan bölme hücrelere kolayca erişilebilir değil genom olduğunu. Böylece, insan kaynakları tabanlı strateji genom vivo içinde düzenleme için geçerli değildir. Son zamanlarda, NHEJ tabanlı strateji verimli gen knock bileşeninde fare doku8için geliştirilmiştir. Yine de, NHEJ tabanlı yöntem genellikle hassas genom düzenleme, özellikle çerçeve füzyon genlerin8oluşturmak çalışırken oluşturmak üzere kavşaklar, indels sunar. Hedeflenen bütünleşmesidir kesin genom düzenleyebilen MMEJ tabanlı. Ancak, sadece mütevazi önceki raporlar5hedeflenen entegrasyon verimliliği artırır. Bu nedenle, kesin hedeflenen entegrasyon içinde vivo verimliliğini artırmak acilen geniş tedavi edici uygulamaları3için gereklidir.
Kısa bir süre önce bir eser bulunmaktadır (HMEJ) katılmadan homoloji-aracılı sonunda gösterdi-strateji, tüm bildirilen stratejileri vitro ve in vivo10içinde en yüksek hedefli entegrasyon verimliliği gösterdi dayalı. Burada, biz HMEJ sisteminin kurulması için bir iletişim kuralı tanımlamak ve aynı zamanda faiz ve donör gen hedefleme tek-Kılavuzu RNA (sgRNA) vektörel çizimler inşaat vektörler barındıran sgRNA hedef siteleri ve ~ 800 bp homoloji silah (şekil 1) . Bu protokol için biz de ayrıntılı adımlar için hedeflenen doku içinde vivoWuppertal'de DNA çakma fareler ve kısa adımlar oluşturmada açıklar. Ayrıca, HMEJ tabanlı strateji bir kanıtı-of-concept çalışma Fah mutasyon düzeltmek ve daha fazla terapötik potansiyelini ortaya Fah- / - Karaciğer yetmezliği fare, kurtarmak için onun yetenek gösterdi.

crispr/cas9-mediated targeted integration in vivo using a homology-mediated end joining-based strategy

Bir umut verici genom düzenleme platformu olarak, CRISPR/Cas9 sistem transgenes hedeflenen entegrasyonu için özellikle verimli genetik manipülasyon için büyük potansiyele sahiptir. Ancak, homolog rekombinasyon (HR) düşük verimliliğini ve çeşitli Indel mutasyonlar (NHEJ) katılmadan homolog olmayan sonu nedeniyle-sigara bölen hücreleri, in vivo genom kalır düzenleme stratejileri büyük bir meydan okuma dayalı. Burada, biz (HMEJ) katılmadan homoloji-aracılı son tarif-esaslı CRISPR/Cas9 sistem verimli vivo içinde kesin hedeflenen tümleştirme için. Bu sistemde, vektör hedeflenen genom ve donör içeren homoloji silah (~ 800 bp) dizileri CRISPR/Cas9 tarafından i ciddi tek Kılavuzu RNA (sgRNA) hedef tarafından çevrili. Bu HMEJ tabanlı strateji verimli transgene Tümleştirme fare zigotları yanı sıra tetkikine vivo içindeelde eder. Ayrıca, bir HMEJ tabanlı strateji fumarylacetoacetate hidrolaz (Fah) mutasyon tetkikine düzeltilmesi için verimli bir yaklaşım sunuyor ve Fahkurtarır-eksikliği bağlı Karaciğer yetmezliği fareler. Birlikte ele alındığında, odaklanan entegrasyonu hedefleyen, bu HMEJ tabanlı strateji uygulamaları, üretimi hedeflenen gen terapileri ve genetiği değiştirilmiş hayvan modelleri de dahil olmak üzere çeşitli için umut verici bir araç sağlar.

Fare embriyo genom HMEJ tabanlı düzenleme: HMEJ tabanlı yöntemi çakma verimliliğini fare zigotları tanımlamak için biz Cas9 mRNA, p2A-mCherry muhabir gene Cdx2 son kodonu ile sigorta için tasarlanmı Cdx2 gen ve HMEJ donör fare zigotları hedefleme sgRNA teslim gen (Şekil 2A). Blastokistlerin kültür içine enjekte zigotları geliştirdi. Çakma etkinliğini değerlendirmek için mCherry floresa...
