Abstract

Sphingosine 1-phosphate receptor 4 (S1P4), which induces cellular migration and prevents apoptosis, was investigated in patients diagnosed with neuroblastoma in our study. The study included 37 neuroblastoma patients and 25 healthy children. After RNA isolation, cDNA were performed and S1P4 gene expression levels were measured in leukocytes. S1P4 gene expression levels presented as mean ± SD were high in the study group. The difference was statistically significant between neuroblastoma patients (0.0387±0.0647) and healthy children (0.0366±0.0238) for S1P4 gene expression levels (p=0.028). Patients given no chemotherapy yet and and those who already completed chemotherapy showed no significant difference statistically (p=0.886). While decreased S1P4 gene expression levels (0.0188±0.0069) were seen in patients receiving maintenance therapy, patients completed chemotherapy had increased S1P4 gene expression levels (0.0322±0.0303). The difference was meaningful (p=0.048). Although S1P4 gene expression levels (0.0310±0.0201) estimated before the beginning of chemotherapy were higher than that of maintenance phase (0.0188±0.0069), the difference was not significant (p=0.158). Higher S1P4 gene expression levels were remarkable in neuroblastoma patients. The suppression of S1P4 gene expression levels during maintenance phase and the increasing of expression in following up without chemotherapy could bring to mind that the chemotherapy could cause to decreased cell migration and/or induction of apoptosis. The effect of S1P4 on the tumor progression and the association with chemotherapy should be investigated in cancer cases

Özet

Davranışı Çalışmamızda nöroblastom tanılı hastalarda hücresel migrasyon ve apoptozisi önleyen sfingozin 1-fosfat reseptör 4 (S1P4) araştırıldı. Çalışma 37 nöroblastom hastalarını ve 25 sağlıklı çocukları içeriyordu. RNA izolasyonundan sonra cDNA oluşturuldu ve hastaların S1P4 gen ekspresyon seviyeleri ölçüldü. Ortalama±standart sapma olarak belirtilen S1P4 gen ekspresyon seviyeleri çalışma grubunda yüksekti. Sağlıklı çocuklar (0.0366±0.0238) ile nöroblastom tanılı hastalar (0.0387±0.0647) arasındaki fark S1P4 gen ekspresyon seviyeleri açısından istatistiksel olarak anlamlıydı (p=0.028). Henüz kemoterapi verilmemiş hastalar ile kemoterapisi çoktan tamamlanmış hastalar arasında belirgin fark yoktu (p=0.886). İdame tedavisi alan hastalarda azalmış S1P4 gen ekspresyon seviyeleri (0.0188±0.0069) görülürken, kemoterapisi tamamlanmış hastaların yükselmiş S1P4 gen ekspresyon seviyeleri (0.0322±0.0303) vardı. Fark anlamlıydı (p= 0.048). Kemoterapi başlanmadan ölçülen S1P4 gen ekspresyon seviyeleri (0.0310±0.0201) idame tedavisinde olanlardan (0.0188±0.0069) yüksek olmasına rağmen, fark anlamlı değildi (p= 0.158). Yüksek S1P4 gen ekspresyon seviyeleri nöroblastomlu hastalarda belirgindi. İdame fazında S1P4 gen ekspresyon seviyelerinin baskılanması ve kemoterapisiz takip edilmede tekrar yükselmesi kemoterapinin hücre migrasyonunun ve/veya apoptozisin indüksiyonunun azalmasına neden olabileceğini akla getirebilir. Kanser vakalarında S1P4’ün tümör progresyonu üzerindeki etkisi ve kemoterapi ile ilişkisi araştırılmalıdır.
