Recent studies imply the effects of micronutrient intake on the development of several cancers including primary brain cancer (PBC). The biological effects of vitamin D, a member of the fat-soluble vitamin family acting as a steroid hormone, was carried out by binding its receptor (VDR) through vitamin D-binding-protein (VDBP). The present study aims to investigate the effects of vitamin D levels and VDR rs2228570, VDR rs731236, VDBP 7041 polymorphisms on PBC development. The study group consisted of 71 patients and 84 controls. Vitamin D levels were determined by high-pressure liquid chromatography where polymorphisms by polymerase-chain-reaction and restriction fragment length polymorphism methods. The distribution of VDR rs2228570 variants in PBC and its subgroups were determined as FF>Ff>ff; VDBP rs7041 variants were TG> GG>TT, however, VDR rs731236 variants were Tt>TT>tt in PBC and meningioma and TT>Tt>tt in glioma. Vitamin D levels were measured below normal levels in all patients and control groups, which shows the deficiency in Turkish society in line with the literature. Our results show that low serum vitamin D level may be an individual risk factor in the development of brain tumors, however, VDR rs2228570 and rs731236 and VDBP rs7041 polymorphisms have no effect on the risk of disease development.

Son çalışmalar, mikrobesin alımının primer beyin kanseri (PBC) dahil olmak üzere çeşitli kanser türlerinin gelişimi üzerindeki etkilerine işaret etmektedir. Yağda çözünen vitaminler sınıfında yer alan ve steroid hormon olarak etki gösteren D vitamini biyolojik etkilerini reseptörü (VDR) ile vitamin D bağlayıcı protein (VDBP) aracılığıyla gerçeklestirmektedir. Çalışmamızda, D vitamini düzeyleri ile VDR rs2228570, VDR rs731236, VDBP 7041 polimorfizmlerinin PBC gelişimi üzerindeki etkilerinin araştırılması amaçlanmıştır. Çalışma grubu, beyin kanseri tanısı konmuş 71 hasta ile 84 sağlıklı bireyden oluşturulmuştur. D vitamini düzeyi, yüksek basınçlı sıvı kromatografisi yöntemiyle, VDR FokI (rs2228570), TaqI (rs731236) ve VDBP rs7041 polimorfizmleri polimeraz zincir reaksiyonu ve restriksiyon parça uzunluk polimorfizmi yöntemleriyle belirlenmiştir. Çalışmamızda VDR FokI gen varyantlarına ait dağılım primer beyin kanseri ve alt gruplarında FF>Ff>ff; VDBP rs7041 varyantları TG>GG>TT olarak, VDR TaqI varyantlarının ise primer beyin kanseri ve meningiomada Tt>TT>tt, gliomada TT>Tt>tt olduğu tespit edilmiştir. D Vitamini düzeyleri tüm hasta gruplarında ve kontrol grubunda normal düzeyinin altında ölçülmüş, bu durum Türk toplumundaki vitamin D düzeylerinin literatürle uyumlu bir şekilde düşük seviyede olduğunu göstermiştir. Çalışmamız sonuçları, beyin tümörleri gelişiminde düşük serum D vitamini seviyesinin bireysel bir risk faktörü olabileceğini, ancak VDR rs2228570 ile rs731236 ve VDBP rs7041 polimorfizmlerinin hastalık gelişim riskine etkisinin olmadığını göstermektedir.
