Yetersiz oksijen hücre ve vücut dokuları sağlandığında hipoksi oluşur. Kök hücre farklılaşması, inflamasyon ve kanser1,2gibi çeşitli fizyolojik ve patolojik süreçler kritik bir rol oynar. Hipoksi-indüklenebilir faktörler (HIFs) oluşan bir oksijen düzenlenir α alt birim ve yapısal ifade β alt birim olarak da bilinen ARNT3heterodimers işlev. Kurulan-α alt birimleri (kurulan-1α, kurulan-2α ve kurulan-3α) ve üç kurulan-β alt birimleri (ARNT/kurulan-1β, ARNT2 ve ARNT3) üç izoformlarının bugüne kadar tespit edilmiştir. Kurulan 2α, kurulan-3α, ARNT2 ve ARNT3 daha ifade desenleri4ile ilgili bir kısıtlama ise kurulan-1α ve ARNT ubiquitously, ifade edilir. Kurulan-1 protein kompleksi hipoksi yanıt anahtar düzenleyicisidir. Hipoksik koşullarda kurulan-1α stabilize hale gelir, o zaman için çekirdek translocates ve ARNT5ile dimerizes. Daha sonra bu karmaşık hipoksi duyarlı öğeler (Xact_s_lastresourcemanager) olarak bilinen belirli nükleotit bağlar ve anjiogenezi, arttığından ve glikoliz6dahil olmak üzere çeşitli işlemlerde ilgili hedef genlerin ifade düzenler. Bu "kanonik" Yanıt yanı sıra, hipoksi sinyal yolu da crosstalk için birden çok hücre tepkisini yolları çentik ve nükleer faktör kappa B (NF-κB) gibi sinyal ile bilinen7,8,9.
Kimliği roman kurulan-1 etkileşen proteinlerin daha iyi yolu sinyal hipoksi anlamak için önemlidir. Oksijen seviyesi duyarsız ve yapısal ifade, ARNT aksine kurulan-1α protein düzeyleri sıkıca Hücresel oksijen düzeyleri tarafından düzenlenmektedir. Normoxia (% 21 oksijen) kurulan-1α hızla bozulmuş10,11proteinlerdir. Kurulan-1α kısa yarılanma normoxia, belirli teknik sorunlar hücre özleri protein tespiti için hem de kurulan 1α etkileşim proteinlerin tanımlanması için sunar. Ayrıca, hipoksik koşulları12,13,14altında çekirdek içine kurulan-1 kompleks de dahil olmak üzere çeşitli transkripsiyon faktörleri translocate. ÜFE çalışmaları için kullanılan geçerli yöntemlerin çoğu fizyolojik olmayan overexpression proteinlerin kullanarak gerçekleştirilir. Bu tür protein overexpression kaynak aşırı yük, stokiometrik dengesizlik, önüne gelenle yatıp kalkan etkileşimleri ve yol modülasyon15,16da dahil olmak üzere birden çok mekanizmalar aracılığıyla farklı hücresel kusurları neden olduğu bildirilmiştir. ÜFE çalışmalar açısından yanlış pozitif veya bile yanlış negatif, sonuçlarına bağlı olarak protein özellikleri ve işlevleri overexpressed proteinlerin protein overexpression yol açabilir. Bu nedenle, ÜFE çalışmaları için geçerli yöntemleri fizyolojik ilgili PPIs hipoksik koşullarda ortaya çıkarmak için değiştirilmesi gerekir. Daha önce kurulan-1 ve Ets aile transkripsiyon faktörü Hes1 organizatörü yanıt hipoksi17katkı GA-bağlayıcı protein (GABP) hipoksik P19 hücrelerdeki arasındaki etkileşimi göstermiştir. Burada, bir co-immunoprecipitation protokol hipoksik koşullarda endojen nükleer proteinler arasında PPIs çalışmaya açıklar. Kurulan-1α ve ARNT arasındaki etkileşimi kavramının bir kanıtı olarak gösterilir. Bu iletişim kuralı transkripsiyon faktörleri ve hipoksik koşullarda transkripsiyon Co düzenleyiciler arasındaki etkileşimleri gösteren için uygundur dahil ama bunlarla sınırlı olmamak üzere kurulan-1 etkileşen proteinler tanımlaması.

co-immunoprecipitation assay using endogenous nuclear proteins from cells cultured under hypoxic conditions

Düşük oksijen düzeyleri (hipoksi) hipoksi-indüklenebilir faktörü 1 (kurulan-1) bir ana düzenleyici hareket karmaşık adaptif yanıt çeşitli tetikler. Kurulan-1 bir heterodimeric oksijen düzenlenir α birimi (kurulan-1α) oluşur ve yapısal genler angiogenez dahil olmak üzere çeşitli işlemlerde dahil düzenleyen β alt birim (kurulan-1β) olarak da bilinen aril hidrokarbon reseptör nükleer ışınlama (ARNT), ifade , arttığından ve glikoliz. Kurulan-1 etkileşen proteinler tanımlaması yolu sinyal hipoksi anlama anahtarıdır. Kurulan-1α istikrar düzenlemenin yanı sıra, hipoksi da kurulan-1α ve ARNT dahil olmak üzere birçok transkripsiyon faktörleri nükleer translocation tetikler. Özellikle, bu tür protein-protein etkileşimleri (PPIs) eğitim için kullanılan geçerli yöntemlerin çoğu nerede protein düzeyleri Yapay protein overexpression artan sistemleri temel alır. Protein overexpression kez zamansal ve mekansal yapılardan kaynaklanan fizyolojik olmayan sonuçlara yol açar. Burada biz değiştirilmiş bir co-immunoprecipitation tarif protokol endojen nükleer proteinler hipoksi tedavi sonrasında ve kurulan-1α ve ARNT arasındaki etkileşimi göstermek için kavramının bir kanıtı olarak. Bu iletişim kuralı, hipoksik hücrelerin hipoksik koşullarda hasat edildi ve Dulbecco'nın Phosphate-Buffered serum fizyolojik (DPBS) yıkama arabellek ayrıca protein yıkımı veya protein kompleksi azaltmak için kullanımdan önce hipoksik koşulları için önceden denge ayrılma sırasında reoxygenation. Ayrıca, nükleer kesirler daha sonra konsantre ve endojen nükleer proteinler stabilize ve sık görülen bir protein overexpression sırasında olası sahte sonuçları önlemek için elde. Bu iletişim kuralı transkripsiyon faktörleri ve transkripsiyon Co düzenleyiciler hipoksik koşullarda endojen ve yerel Hofstede göstermek için kullanılabilir.

Hücresel yanıt hipoksi, ifade olarak değerlendirmek için düzeyleri ve kurulan-1 karmaşık aşağıdaki hipoksi tedavi bileşenlerinin hücre altı yerelleştirme incelenmiş. HEK293A hücreleri 4 h için hipoksik koşullarda kültürlü veya normoxia denetimler olarak devam etti. Bütün hücre içinde kurulan-1α ve ARNT protein düzeyleri incelenmiş veya nükleer/sitoplazmik tarafından western blot ayıklar. Toplam hücresel lysates ARNT düzeyleri önemli ölçüde değildi, an...
