As revealed by our analysis of mRNA expression in samples of meningioma tissue subjected to hypoxic ischemic preconditioning, the expression of HIF-1α and its target genes (VEGF-A, c-Myc, and GLUT1) is not affected by this procedure, whereas AhR, ARNT, and NcoA2 expressions significantly decreases. The gene discussed is AHR; the disease is meningioma.
