FBLN2 and meningioma: Real-time Quantitative Polymerase Chain Reaction (RT-qPCR) gene expression studies on a validation sample set showed that FBLN2 gene expression was significantly higher (Log2Fc of Gd II vs. Gd I = 5.36; p < 0.05) in grade II (n = 6) versus grade I (n = 7) meningioma cells (Figure 1d).
