Abstract

Aim: MicroRNAs (miR) have an essential role on the regulated gene expression in the human genome. In recent years, a specific miR group was called to angio-miRs due to their role in the angiogenesis, and recent study showed that they involved in the pathogenesis of gliomas. In this study, we investigated the changes in the expression profiles of angio-miRs in glioblastoma cells and identified relationship between these genes and invasion and tumor growth. Materials and Methods: In this study, glioblastoma tumor spheroids were obtained using the human glioblastoma cell line U-87 MG. 50 nM, 100 nM and 200 nM ruxolitinib were applied to tumor spheroids for 48 hours by using Matrigell method. Tumor volume and invasion formation relative % tumor growth and relative % invasion area were measured in glioblastoma tumor spheroids after 48 hours of treatment. At the same time, quantitative real-time polymerase chain reaction (qRT-PZR) analysis was performed and miR expression profiles were determined. The most important (importance features) miRNAs selected along with the heatmap and volcano plot analyzes were used to display the pattern of the differentially expressed miRs using normalized miR expression profiles. Results: When the effect of 50 nM, 100 nM and 200 nM ruxolitinib administration to tumor spheroids on tumor volume and invasion was evaluated, a significant difference was found at each dose applied. However, at the dose of 200 nM ruxolitinib, it was observed that the inhibitory effect of tumor invasion was the highest. When miR expression profiles obtained by qRT-PZR test with 200 nM ruxolitinib adminisration were evaluated, it was determined that the expression profiles of 10 miRs increased and the expression profiles of 4 miRs decreased. Conclusion: In conclusion, angio-miR expression profiles are important because they enable us to better understand the prognostic process of gliomas. Because of their multiple silencing properties, they may contribute to the clinic with further studies in terms of their use as new therapeutic targets and prognostic biomarkers for glioblastoma.

Özet

Amaç: MikroRNA’lar (miR), insan genomunda gen ifadesinin düzenlenmesinde önemli rolü olan düzenleyicilerdir. Son yıllarda anjiyogenezde rol oynayan spesifik bir miR grubu tanımlanmış (anjiyo-miR) ve bazı anjiyo-miR’lerin gliomalarda etkin rol oynadıkları ortaya konmuştur. Bu çalışmada, glioblastoma hücrelerindeki anjiyo-miR’lerin ifade değerlerindeki değişiklikleri ve bu değişikliklerin invazyon ve tümör büyümesi ile ilişkisini araştırdık. Gereç ve Yöntem: Bu çalışmada, insan glioblastoma hücre hattı U-87 MG kullanılarak glioblastoma tümör sferoidleri elde edildi. Matrigel yöntemi ile tümör sferoidlerine 48 saat süresince 50 nM, 100 nM and 200 nM ruksolitinib uygulandı. Kırk sekiz saat tedaviden sonra glioblastoma tümör sferoidlerinde tümör hacmi ve invazyon oluşumu relatif yüzde tümör gelişimi ve relatif yüzde invazyon alanı ölçüldü. Aynı zamanda, niceliksel gerçek zamanlı polimeraz zincir reaksiyonu (qRT-PZR) analizi yapıldı ve miR ifade değerleri belirlendi. Farklı şekillerde ifade edilen miRNA’ların modelini görüntülemek için normalize edilen miRNA ifade değerleri kullanılarak heatmap ve volcano plot analizleri ile seçilen en önemli (importance features) miRNA’lar gösterildi. Bulgular: Tümör sferoidlerine 50 nM, 100 nM ve 200 nM ruksolitinib uygulamasının tümör hacmi ve invazyon üzerine etkisi değerlendirildiğinde, uygulanan her dozda anlamlı fark saptandı. Ancak 200 nM ruksolitinib dozunda tümör yayılımını engelleyici etkisinin en yüksek olduğu gözlendi. 200 nM ruksolitinib uygulaması ile qRT-PZR testi ile elde edilen miR ifade değerleri incelendiğinde 10 miR’nin ifade değerlerinin arttığı, 4 tanesinin ifade değerlerinin ise azaldığı belirlendi. Sonuç: Sonuç olarak anjiyo-miR ifade değerleri gliomaların prognostik sürecini daha iyi anlamamızı sağlayabilmeleri açısından önemlidirler. Çoklu susturma özellikleri sayesinde glioblastomalar için yeni terapötik hedefler ve prognostik biyobelirteçler olarak kullanılabilmesi açısından ileri çalışmalarla kliniğe katkı sağlayabilirler
