Bu iletişim kuralı, değilse dikkatle takip önemli ölçüde azaltılmış protein verim veya kirlenme hücresel DNA ile sonuçlanabilir birden çok adım içerir. Bu sabit hücre hücresel DNA etiketli saf ve değil emin olmak için tüm deneyler için kullanılır önemlidir. HSV-1 genomu sentez için hücresel DNA polimeraz kullanmaz çünkü bu hücresel DNA polimerazlar protein örnek yokluğunda tarafından onaylanabilir. EdC etiketleme ve çekirdekleri adımları hasat sırasında örnekleri her eşit işlenir ...

Virüs temel işlevlerini gerçekleştirecek ve bu nedenle enfeksiyon viral gen ekspresyonu, çoğaltma, tamir, Rekombinasyon ve ulaşım dahil olmak üzere önemli yönlerini kolaylaştırmak için ana bilgisayar etkenlere bağlı için sınırlı bir kapasiteye sahip. Bu ana faktörler faaliyetleri genellikle virally kodlanmış proteinler tarafından artar. Ayrıca, virüs algılama ve girişim tarafından hücresel yanıt için viral enfeksiyon kaçınmak gerekir. Bu nedenle, virüs ana etkileşimler enfeksiyon sonucu dikte. Büyük önem nasıl virüs viral işlemleri kolaylaştırmak için hücresel makine adapte hücresel ortamı alter anlaşılmasıdır. Özel ilgi hangi faktörler ve süreçleri viral genom bulaşıcı döngüsü boyunca hareket tespitidir.
Herpes simplex virüsü tip 1 (HSV-1) bir çift DNA virüs bulaşan insan nüfusunun önemli bir kısmı mahsur olduğunu. Enfeksiyonun ilk bir saat içinde nerede viral DNA (vDNA) çoğaltma1ile koordineli olarak viral gen ekspresyonu sıralı bir çağlayan ensues çekirdeği, viral genom girer. Çekirdek, genleri tabi epigenetik düzenleme, onarım ve rekombinasyon geçmesi ve öyle ki ilk döl virions 6 saat içinde üretilen capsids paketlenir. Viral genom ilişkili proteinler enfeksiyon seyri boyunca kapsamlı değerlendirme viral genom hareket ve hangi viral ve hücresel faktörler görmemizi sağlayacak süreçleri moleküler ayrıntılarını araştırmak için zemin enfeksiyon çeşitli aşamalarında yer alırlar.
Benzeşme arıtma ilişkili hücresel proteinler2,3,4,5 analizi için viral proteinlerin ana faktörler viral enfeksiyon katılan incelenmesi için önceki yöntemleri içerir , 6 , 7 , 8 , 9. bu deneyleri ana bilgisayar antiviral yanıt yanı sıra viral Kromatin değişiklik, gen ekspresyonu, enstrümantal hücresel faktörler katılan tanımlanması için edilmiş ve DNA tamir. Ancak, vDNA ilişkilendirmesiyle etkileşimleri bağlıdır ve proteomik yalnızca belirli bir viral faktör bir fonksiyonu olarak oluşan etkileşimleri içgörü sağlamak olup olmadığını tespit etmek zordur. Kromatin immunoprecipitation (ChIP) nerede belirli viral ve hücresel proteinler viral genom10,11,12,13,14 ' e bağlamak tanımlamak için kullanılan , 15 ve immunocytochemistry ile kombine floresan In situ hibridizasyon (balık) vDNA16,17,18ile, colocalize hücresel faktörler görselleştirme sağladı 19 , 20. bu deneyleri kayma ve temporal analiz için izin. Ancak, çok özel antikorlar, sınırlı hassasiyet ve virüs ana bilgisayar etkileşimleri önceki fikir ihtiyacını ihtiyacını sınırlamaları içerir. Bu nedenle bir yöntemi iPOND (yalıtım doğmakta olan DNA üzerinde proteinlerin)21 tarihinde göre geliştirilen ve seçmeli olarak etiket ve vDNA üzerinden arındırmak için aniPOND (hızlandırılmış yerli iPOND)22 viral genom tarafsız tanımlanması için hücreleri enfekte Kütle spektrometresi ile ilişkili proteinler. iPOND hücresel çoğaltma çatal dynamics soruşturma için vesile olmuştur.
Enfekte hücreleri üzerinden viral genom seçici arıtma için vDNA çoğaltılıyor modifiye ethynyl nükleozitler, 5-ethynyl-2´-deoxyuridine (EdU) veya 5-ethynyl-2´-kovalent tarafından takip deoxycytidine (EdC) (Resim 1), taşır konjugasyon için biotin azid viral genom ve ilişkili proteinler streptavidin kaplı boncuk (şekil 2B) üzerinde tek adım arıtma kolaylaştırmak için kimya'ı tıklatın. Önemlisi, enfeksiyonlar hücresel DNA ikileşmesi belirli vDNA etiketleme etkinleştirmek için nişanlı değil sabit hücrelerde, devam etmektedir. Ayrıca, HSV-1 enfeksiyonu hücre döngüsü tutuklama nedenleri ve hücresel DNA çoğaltma23,24engeller. Virüs önce gelen viral genom (şekil 1A) ile ilişkili protein analizi için enfeksiyon prelabeled ya da yeni sentezlenmiş vDNA (şekil 1B) ile ilişkili protein analizi için DNA ikileşmesi sırasında etiketli 25. Ayrıca, nabız chase analiz doğa viral çoğaltma çatal (şekil 1 c)26ile ilişkili proteinlerin araştırmak için kullanılabilir. Buna ek olarak, vDNA ethynyl-modified kovalent protein dinamiği (şekil 2A ve şekil 3) kayma soruşturma için bir fluorophore için Birleşik. Görüntüleme vDNA doğrudan görselleştirme için sağlar ve vDNA-protein etkileşimleri doğrulama için ücretsiz bir yaklaşımdır ve viral genom enfeksiyon boyunca izlemek için adapte edilebilir. Biz bu yaklaşımlar daha da herpesviral enfeksiyon, gecikme süresi ve yeniden etkinleştirme, dahil olmak üzere herhangi bir yönünü çalışmaya ve diğer DNA virüsleri çalışmaya değiştirilebiliyordu tahmin. Ayrıca, 5-ethynyl üridin ile etiketleme (AB) RNA viral genom analizi için izin verebilir.

purification of viral dna for the identification of associated viral and cellular proteins

Bu iletişim kuralı kimliği için enfekte hücreleri DNA'dan (HSV-1) ilişkili herpes simplex virüsü tip 1 yalıtmak için viral ve hücresel proteinler tarafından kütle spektrometresi hedefidir. Her ne kadar viral genom ile etkileşim proteinler enfeksiyon sonucu belirlemede önemli rol oynarlar, viral genom ilişkili proteinler kapsamlı bir analiz daha önce mümkün değildi. Burada biz HSV-1 genleri enfekte hücreleri doğrudan arıtma sağlayan bir yöntem göstermek. Viral DNA çoğaltılıyor seçerek bir ALKİN fonksiyonel grup içeren değiştirilmiş nükleotit ile etiketlenir. Etiketli DNA sonra özellikle ve geri dönüşümsüz tagged biotin azid bir bakır (I) ile kovalent eki ile-katalize azid ALKİN reaksiyon cycloaddition ya da tıklayın. Biotin öğesini DNA streptavidin kaplı boncuk saflaştırılmış ve ilişkili protein eluted ve kütle spektrometresi tarafından tanımlanan. Bu yöntem seçici hedefleme ve yalıtım HSV-1 çoğaltma çatal veya karmaşık biyolojik ortamlardan bütün genleri etkinleştirir. Ayrıca, bu yaklaşım adaptasyon herpesviral enfeksiyon, çeşitli yönlerinin yanı sıra diğer DNA virüsleri genleri incelenmesi incelenmesi için izin verir.

Tıklayın kimya kullanım hücrelerden DNA arıtma için iPOND yöntemi21tarafından ilk başarılı oldu. İPOND hücresel çoğaltma çatal ilişkili proteinlerin tanımlanması için arındırmak için amaçtır. Bu teknik özellikle enfeksiyon sırasında vDNA protein etkileşimleri çalışmaya adapte olması.
