Özet<br />

Akciğer kanseri tüm kanser türleri arasında görülme sıklığı olarak ikinci sırada, kanser sebepli ölümler<br />

arasında ise ilk sırada gelmektedir. Survivin geni 17q25 kromozomal bölgesinde lokalizedir ve 142 amino<br />

asitten oluşan bir protein kodlar. Survivin (BIRC5) apoptozu düzenleyen önemli bir protein ailesi olan<br />

apoptoz proteinlerinin inhibitörü (IAPs) olarak ilk bulunan inhibitörlerden biridir ve özellikle kanser<br />

hücrelerinde ifadesi gerçekleşir. Survivin genindeki polimorfizm survivin üretimi ve aktivitesine etki<br />

edebilir, bu nedenle akciğer kanserine hassasiyet sağlar. Survivin genindeki aşırı ifadenin çok çeşitli<br />

maligniteleri içeren kanser türlerinde hastalık gelişimi, nüksü ve prognozu ile ilişkili olduğu bilinmektedir.<br />

Bu çalışmada bir Türk popülasyonunda survivin geni promotör bölgesi üzerinde bulunan -625G/C gen<br />

polimorfizmi ile küçük hücreli dışı akciğer kanseri arasında, hastalığın gelişimi ile ilgili olası ilişkilerin<br />

araştırılması amaçl<strong>and</strong>ı. Çalışmaya 146 hasta, 98 kon<strong>tr</strong>ol olgu dahil edildi. Yöntem olarak PCR-RFLP tekniği<br />

kullanıldı. Sonuç olarak survivin -625G/C genotip dağılımları incelendiğinde hasta ve kon<strong>tr</strong>ol grupları<br />

arasında istatistiksel olarak anlamlı fark olmadığı tespit edilmiştir.<br />

Anahtar kelimeler: Küçük hücreli dışı akciğer kanseri, survivin, gen polimorfizmi, PCR-RFLP, biyobelirteç.<br />

Investigation <strong>of</strong> the association <strong>of</strong> survivin gene -625G/C polymorphism in non-small cell<br />

lung cancer<br />

Abs<strong>tr</strong>act<br />

Lung cancer is the second most common cancer type diagnosed <strong>and</strong> first in cancer related deaths among all<br />

cancers worldwide. The survivin gene is located on human chromosome 17q25, encoding a protein consisting<br />

<strong>of</strong> 142 amino acids. Survivin is one <strong>of</strong> the first reported inhibitors <strong>of</strong> apoptosis proteins, which is an<br />

important family <strong>of</strong> proteins that regulate apoptosis. Survivin gene polymorphism may affect the survivin<br />

production <strong>and</strong> activity, thus providing sensitivity for the development <strong>of</strong> lung cancer. The overexpression <strong>of</strong><br />

survivin gene was found to be associated with disease development, recurrence <strong>and</strong> prognosis in various<br />

malignancies, including cancers. In this study the demons<strong>tr</strong>ation <strong>of</strong> the prognosis related associations<br />

between the -625G/C gene polymorphism located on the survivin promoter region <strong>and</strong> non small cell lung<br />

cancer in a Turkish population was aimed. 146 patients <strong>and</strong> 98 con<strong>tr</strong>ol subjects included to the study. PCR-<br />

RFLP technique was used as the method. According to survivin -625G/C genotype dis<strong>tr</strong>ibution analysis, no<br />

statistically significant difference between patients <strong>and</strong> con<strong>tr</strong>ols were found.<br />

Keywords: Non small cell lung cancer, survivin, gene polymorphism, PCR-RFLP, biomarker.
