Çekirdeğin içinde olan fonksiyonlar en yakından gen regülasyonu ile bağlantılı proteomlarda bulunur. Erişkin memeli kardiyomiyosit çekirdeklerinin nükleuslu hücrelerin oranı yüksek, 1 DNA ağırlıklı heterokromatik durumu nedeniyle benzersizdir ve geliştirme sırasında interfaz kalıcı bir devlet yetişkin çekirdekleri işler kardiyomiyosit-olmayan bölünmesi doğası. 2 Transkripsiyonal düzenleme ve Hastalığın sıra bu proteinlerin hastalığı sırasında meydana transkripsiyonel programları değişiklikleri kontrol nasıl bu organ, 3-5 okudu ama ne nispeten keşfedilmemiş kalır DNA paketlenmesi ve ifade sorumlu nükleer proteinler oynadığı rol ve oylandı. 6 geliştirilen yılında dünya, kalp hastalığı erkekler hem de kadınlar için ölüm bir numaralı nedenidir. nükleer proteinleri bu hastalığın ilerlemesini düzenleyen işbirliği nasıl 7 Insight güncel tedavi o ilerleyen için kritikeçenekler. Kütle spektrometresi bu hastalıkla nasıl bu proteinlerin bolluğu değişiklikler için nükleer proteom ve göreli kantifikasyon tarafsız bir açıklama sağlayan bu soruların iletilebileceği ideal bir araçtır. Son zamanlara kadar memeli nükleer protein kompleksleri, 8-13 için çeşitli proteomik çalışmalar varken 14 kardiyak nükleer proteom inceleyen sadece bir çalışma olmuştur ve oldukça nükleer alt bölmeleri düzeyinde proteom keşfetmek yerine, tüm çekirdek olarak kabul . Büyük bir kısmı 15, bu iş sıkıntısı kardiyak çekirdeklerin tecrit zorluk kaynaklanmaktadır. Kardiyak çekirdekler miyosit daralma değiştiren kendi genel şekli. 16 Ayrıca, kardiyomiyositlerde hacmi 17 ile% 40 mitokondri olduğu ölçüde, onlar endoplazmik retikulum birden uzantıları aracılığıyla bağlı bir katı ve yoğun aktin-miyozin aygıtı içinde ortaya çıktığı Necessitadiğer organeller dışında çekirdeğin zenginleştirme tes. Burada biyolojik ilgili bölmeye kardiyak nükleer zenginleştirme ve daha fazla fraksiyonasyon için bir protokol açıklar.
