AHR and meningioma: Here, we report the results of a study on the expression of key genes of the HIF-1α and AhR signaling pathways, of their heterodimerization partner ARNT, of nuclear receptor coactivator NcoA2, and of HIF-1α target gene vascular endothelial cell growth factor VEGF-A, proto-oncogene c-Myc, and glucose transporter GLUT1 in the tissue of benign (WHOGr1) meningiomas.
