mapping bacterial functional networks and pathways in escherichia coli using synthetic genetic arrays

Fenotipleri fiziksel (protein-protein gibi) ve fonksiyonel (örneğin, gen-geni ya da gen) etkileşimleri (GI) 1 karmaşık bir dizi ile belirlenmiştir. Fiziksel etkileşim bakteriyel protein kompleksleri olarak ilişkili oldukları işaret olsa da, onlar mutlaka yolunun düzey fonksiyonel relationships1 açıklamayız. İki silinmiş veya inaktif genleri taşıyan çift mutantların büyüme ölçülür ve karşılık gelen tek mutantlar ile karşılaştırıldığında hangi GI ekranlar, lokusları arasında epistatik bağımlılıkları aydınlatmak ve dolayısıyla yeni fonksiyonel ilişkiler 2 sorgulamak ve keşfetmek için bir araç sağlayabilir. Büyük ölçekli GI haritaları maya 3-7 gibi ökaryotik organizmalar için bildirilen, ancak GI bilgi bakteriyel genomlar işlevsel açıklama engellemektedir prokaryotlar 8 için seyrek kalır edilmiştir. Bu amaçla, ve diğerleri, yüksek verim kantitatif bakteri GI tarama yöntemleri, 9, 10 geliştirdik </&gt; sup. Burada, kantitatif E. gerçekleştirmek için gereken önemli adımları sunmak sistemik oluşturmak ve bir koloni dizisi biçiminde çift mutantlar çok sayıda spor ölçmek için doğal bakteriyel konjugasyon ve homolog rekombinasyon kullanarak coli bir genom-ölçekli 9 Sentetik Genetik Array (eSGA) tarama prosedürü,. Kısaca, bir robot aktarmak için kullanılır , konjugasyon yoluyla, kloramfenikol (Cm) - İşaretli F-alıcı suşlar - mühendislik Hfr gelen mutant alleli (rekombinasyon Yüksek frekans) kanamisin sıralı bir dizi (Kan) içine &#39;donör suşları&#39; olarak işaretlenmiş. Genellikle, biz kayıp fonksiyon-gerekli olmayan gen delesyonlar taşıyan tek mutantlar (&#39;Keio&#39; koleksiyonu 11 gibi) ve temel gen mutasyonları hypomorphic (azaltılmış protein ekspresyonu, istikrar, ya da etkinlik 9, 12, 13 görüşmekte yani allelleri) kullanın non-esansiyel ve esansiyel genler, res fonksiyonel dernekleri sorgulamakpectively. Homolog yeniden birleşme ve bunu takip eden genetik değiş tokuş aracılı sonra, elde edilen çift mutant hem de antibiyotik içeren katı ortam üzerinde seçilir. Akıbet sonra, plakaları dijital görüntülü ve koloni boyutları nicel bir in-house otomatik görüntü işleme sistemi 14 kullanılarak puanlanır. Yaktığımız bir çift mutant büyüme oranı beklenen 9 daha da belirgin olarak daha iyi veya daha kötü olduğu zaman ortaya çıkar. Ağırlaştırıcı (veya negatif) yaktığımız çoğu aynı temel süreç 2 çarpacak telafi yollarının gelen genlerin çiftleri kaybı fonksiyon-mutasyonlar arasındaki sonuçlanabilir. Burada, tek bir gen kaybı ya da tek bir mutasyona uğramış uygun bir şekilde, arabelleğe. Ancak, her iki yollarının kaybı zararlı olduğunu ve sentetik öldürücülüğü veya hastalık (yani yavaş büyüme) ile sonuçlanır. Tersine, hafifletilmesi (veya pozitif) etkileşimleri aynı yolu ya da karmaşık protein 2 genleri arasında meydana gelebilecektek başına ya da gen silinmesi sık sık yoldan veya daha fazla ilave pertürbasyonlar, böylece büyüme aktivitesini azaltır, ve olmayan bu tür karmaşık ve normal fonksiyonunu karıştırmayı için yeterlidir. Genel olarak, sistematik olarak tanımlanması ve GI ağları analiz diğer yaklaşımlar tarafından cevapsız yolağı düzeyde bilgi 9 varılabilir hangi genlerin, çok sayıda arasındaki fonksiyonel ilişkilerin tarafsız, global haritalar sağlayabilir.

GIs reveal functional relationships between genes. Similarly, since genes in the same pathway display similar GI patterns and the GI profile similarity represents the congruency of phenotypes, we can group functionally related genes into pathways by clustering their GI profiles. Integrating GI and GI correlation networks with physical interaction information or other association data, such as genomic context (GC) relationships can also reveal the organization of higher-order functional modules that define core bio...
