Bu teknoloji geliştirdi tRNase Z L (ya da 3 &#39;tRNase), tRNA 3&#39; işleme endoribonuclease özelliklerine dayanarak olmuştur: Bir tanıyarak yapay küçük bir rehber RNA (sgRNA) yönetimindeki herhangi beklenen yerinde herhangi bir hedef RNA yarabilir 9 - hedef RNA ve sgRNA 2 arasında oluşturulmuş önceden tRNA benzeri ya da mikro-ön-tRNA-benzeri bir yapı. uzunluğunda nt genellikle 7-31 olan sgRNA, dört gruba, 5&#39;-yarım-tRNA, heptamer RNA, 14-nt lineer RNA ve kanca RNA kategorize edilir. 15 - Biz hücreler 10 canlı içine çeşitli yapay olarak tasarlanmış sgRNAlardır sunarak DOĞRU gen susturma etkinliğini göstermiştir. Biz de sgRNAlardır hücrelerin wi tarafından alınabilir göstermiştirherhangi bir transfeksiyon reaktifleri thout ve hedef RNA seviyelerini bozulduğunu ve / veya insan kanser hücrelerinin 16 apoptosis doğurabileceği - 18. 21 - DOĞRU gen susturma tRNase Z L ve doğal sgRNAlardır 19 üzerinden hücre içi ve hücreler arası gen düzenleyici ağ sistemi üzerinde çalışması için görünür. Kan kanserleri 22 potansiyel terapötik heptamer tipi sgRNAlardır aramak için 156 heptamer tipi sgRNAlardır içeren bir sgRNA kütüphane inşa ettik. İnsan miyeloma ve lösemi hücrelerinin ömrü üzerindeki etkisi için filtrelenmiş ve 20 tanesi etkin kanser hücre çizgilerinin en az biri apoptosis bulmuşlardır. Ve bunların 4 fare ksenogreft deneylerinde tümör büyüme oranlarını azaltmak için gösterilmiştir. Burada kan kanserlerine karşı potansiyel terapötik ilaçların bir heptamer tipi sgRNA kitaplığının taranması için bir protokol mevcut. protokol nasıl dahilhücre canlılığı ve nasıl daha fazla flow sitometri ile etkili sgRNAlardır değerlendirmek için her sgRNA etkisini değerlendirmek için nasıl sgRNA kütüphanesini oluşturmak için. Bunlar, bu protokolde yer almaz, ancak fare ksenogreft modellerinde sgRNA hücresel hedef RNAlar için analiz ve etkili sgRNAlardır değerlendirilmesi, geleneksel yöntemlerle 17,22 göre gerçekleştirilebilir.
