The present study aims to assess and further validate cytokines with probable effects on proliferation and maturation of blood cells in AML.Materials and Methods: Gene expression levels of IL-1?, IL-10, IL-8, TNF-?, and IFN-? were analyzed before and after chemotherapy and after granulocyte colony-stimulating factor (G-CSF) therapy in 46 AML patients by an in-house quantitative comparative RT-PCR method.Results:Our findings indicated that although the gene expression level of TNF-? was almost constant in all 3 samples, IL-1?, IL-8, and IL-10 expression levels showed a decrease after chemotherapy and an increase after G-CSF therapy.

Abstract

Objective: One of the major goals of cancer treatment is the monitoring of chemotherapeutic protocols. Quantitative and comparative cytokine expression profiling could be reliable to be used for biomarkers in deadly and fast-growing cancers such as acute myeloid leukemia (AML). The present study aims to assess and further validate cytokines with probable effects on proliferation and maturation of blood cells in AML.Materials and Methods: Gene expression levels of IL-1?, IL-10, IL-8, TNF-?, and IFN-? were analyzed before and after chemotherapy and after granulocyte colony-stimulating factor (G-CSF) therapy in 46 AML patients by an in-house quantitative comparative RT-PCR method.Results:Our findings indicated that although the gene expression level of TNF-? was almost constant in all 3 samples, IL-1?, IL-8, and IL-10 expression levels showed a decrease after chemotherapy and an increase after G-CSF therapy. On the other hand, the expression level of IFN-? had a different pattern with an increase after chemotherapy and a decrease after G-CSF therapy. Conclusion:Taken together, the results of this study are in support of the idea that the analyzed cytokines could be useful biomarkers for AML treatment monitoring. However, further molecular epidemiological investigations are suggested to elaborate more cancer monitoring biomarkers.

Özet

Amaç:Kanser tedavisinin en önemli hedeflerinden bir tanesi de kemoterapi protokollerinin monitörizasyonudur. Niceliksel ve karşılaştırılabilir sitokin ekspresyon profili, akut myeloid lösemi (AML) gibi hızlı ilerleyen ve ölümcül kanserlerde biyobelirteç olarak kullanılmaya uygun görünmektedir. Bu çalışmada, sitokinlerin AML'deki kan hücrelerinin çoğalma ve olgunlaşması üzerine olası etkilerinin değerlendirilmesi ve daha da ötesi doğrulanması amaçlanmıştır.Gereç ve Yöntemler:Hastanede yatan 46 AML hastasında, kemoterapi öncesi, sonrası ve granülosit koloni sitimüle edici faktör (G-CSF) uygulaması sonrası olacak şekilde, niceliksel karşılaştırmalı RT-PCR yöntemi ile IL-1?, IL-10, IL-8, TNF-? ve IFN-?'nin gen ekspresyon düzeyleri analiz edildi.Bulgular: Sonuçlarımız, TNF-? gen ekspresyon düzeyinin her üç durumda da sabit kalmasına karşın, IL-1?, IL-8 ve IL-10 ekspresyon düzeylerinin kemoterapi uygulamasından sonra düşerken, G-CSF tedavisinin ardından ise yükseldiğini ortaya koydu. Diğer yandan; IFN-? ekspresyon düzeyleri ise, kemoterapiden sonra yükselip, G-CSF tedavisinin ardından düşerek tamamen farklı bir paterne sahip olduğunu gösterdi. Sonuç: Birlikte ele alındığında, AML tedavisinin monitörizasyonunda sitokin ekspresyon analizinin yararlı bir biyobelirteç olduğu düşüncesi bu çalışma sonuçları ile destek bulmuştur. Bununla birlikte, gelecek epidemiyolojik moleküler çalışmaların çok daha fazla kanser takip biyobelirtecinin belirlenmesinde yol gösterici olacağı aşikardır.
