Abstract

Objective: Immune activation plays a critical role in the immune response against cancer. Although several genetic factors are es- tablished with regard to the development of acute lymphoblastic leukemia (ALL), the role of immunogenic genes in ALL patho- genesis remains elusive. Toll-like receptor (TLR) and nucleotide- binding oligomerization domain containing protein 2 (NOD2) receptors are essential in immune response. The aim of the study was to investigate the association between TLR4 Asp299Gly, TLR4 Thr399Ile, NOD2 Arg702Trp, NOD2 Gly908Arg, and NOD2 Leu1007fsinsC polymorphisms and the risk of child- hood ALL. Methods: Genotype distributions of TLR and NOD2 polymor- phisms were determined by real-time polymerase chain reaction in 102 ALL patients and 110 sex- and age-matched healthy in- dividuals. Results: We found no significant differences between the ALL and control groups in terms of TLR4 Asp299Gly, TLR4 Thr399Ile, NOD2 Arg702Trp, NOD2 Gly908Arg, and NOD2 Leu1007fsinsC polymorphisms (p>0.05). However, we found markedly negative correlation between the C–G haplotype (rs2066844-rs2066845) and the risk of ALL (p=0.055). Conclusion: The results showed that the TLR and NOD2 poly- morphisms were not associated with the risk of ALL. However, these results need to be confirmed by further, larger case-control studies.

Özet

Amaç: İmmün aktivasyon kansere karşı immün cevapta kritik bir rol oynamaktadır. Akut lenfoblastik lösemi (ALL) gelişimi ile ilişkili çeşitli genetik faktörler iyi tanımlanmasına rağmen, immü- nojenik genlerin ALL patogenezindeki rolü tam olarak açıklığa kavuşmamıştır. Toll-like receptor (TLR) ve nucleotide binding oli- gomerization domain containing protein 2 (NOD2) reseptörleri immün cevabın başlamasında merkezi rol oynarlar. Biz çalışma- mızda TLR4 Asp299Gly, TLR4 Thr399Ile, NOD2 Arg702Trp, NOD2 Gly908Arg ve NOD2 Leu1007fsinsC polimorfizmleri ile çocukluk çağı ALL riski arasındaki ilişkiyi araştırmayı amaçladık. Yöntemler: TLR4 ve NOD2 polimorfizmlerine ait genotip dağı- lımları çocukluk çağı 102 ALL hastasında ve benzer yaş ve cinsi- yette 110 sağlıklı bireyde Real-time polimeraz zincir reaksiyonu (Real-time PZR) yöntemi kullanılarak belirlendi. Bulgular: TLR4 Asp299Gly, TLR4 Thr399Ile, NOD2 Arg702Trp, NOD2 Gly908Arg ve NOD2 Leu1007fsinsC poli- morfizmleri için çalışma gruplarının genotip dağılımları arasında istatistiksel olarak anlamlı bir fark saptamadık (p>0,05). Fakat, C-G haplotipi (rs2066844-rs2066845) ve ALL riski arasında ne- gatif yönde sınırda anlamlılık bulduk (p=0,055). Sonuç: Bu çalışma sonuçları TLR4 ve NOD2 polimorfizmleri- nin ALL riski ile ilişkili olmadığını göstermektedir. Bu sonuçla- rın daha büyük sayıdaki vaka-kontrol çalışmaları ile doğrulan- ması gerekmektedir.
