Abstract

AIm: Meningiomas are one of the most common benign intracranial tumors, making up nearly one third of all primary intracranial tumors. The majority of meningiomas have benign histological features and total resection is associated with favourable prognosis. Atypical and malignant meningiomas are associated with increased risk of recurrence. In the present study we set out to investigate the role of nestin mRNA levels and miR-21 in meningiomas. mATeRIAL and meTHods: We studied 17 patients with meningiomas that were treated surgically in our institute. Clinical variables that were analyzed were age, sex and histology. The expression of stem cell marker nestin mRNA levels and miR-21 was investigated in tissue samples by qRT-PCR. ResuLTs: Considerable levels of both miR-21 and nestin mRNA were found. Atypical and anaplastic meningiomas had higher expression of both miR-21 and nestin compared to benign tumors. Furthermore, a trend towards a positive correlation between miR-21 and nestin mRNA levels was also found. CoNCLusIoN: Increased miR-21 and nestin mRNA levels were found in anaplastic meningiomas, in which recurrence is common, and the role of miR-21 and Nestin in meningiomas therefore warrants further investigation.

Özet

AmAÇ: Menenjiyomlar en sık görülen benign intrakraniyal tümörlerdendir ve tüm primer intrakraniyal tümörlerin neredeyse üçte birini oluştururlar. Menenjiyomların çoğunda benign histolojik özellikler mevcuttur ve total rezeksiyon olumlu bir prognozla ilişkilidir. Atipik ve malign menenjiyomlar artmış nüks riskiyle ilişkilidir. Çalışmada, menenjiyomlarda nestin mRNA seviyeleri ve miR-21 rolünü incelemeyi amaçladık. yÖNTem ve GeReÇLeR: Enstitümüzde cerrahi tedavi gören 17 menenjiyom hastasını inceledik. Analiz edilen klinik değişkenler yaş, cinsiyet ve histolojiydi. Kök hücre işareti nestin mRNA seviyeleri ve miR-21 ekspresyonu doku örneklerinde qRT-PCR ile incelendi. BuLGuLAR: Hem miR-21 hem nestin mRNA düzeyleri önemli bulundu. Atipik ve anaplastik menenjiyomlarda benign tümörlere göre hem miR-21 hem nestin ekspresyonu daha yüksekti. Ayrıca miR-21 ve nestin mRNA seviyeleri arasında pozitif korelasyon açısından bir eğilim de bulundu. soNuÇ: Nüksün sık görüldüğü anaplastik menenjiyomlarda artmış miR-21 ve nestin mRNA seviyeleri bulundu. Menenjiyomlarda miR-21 ve nestin rolünün daha ileri incelenmesi gerekir.
