SLC2A1 and meningioma: The analysis of the expression of HIF-1α and HIF-α target genes (VEGF-A, GLUT1, and c-Myc) in meningioma tissue samples obtained during surgical removal of the tumor in patients either with or without prior endovascular embolization revealed no statistically significant differences in the mRNA levels of these genes between the nonembolized and embolized meningiomas (Figure 1).
