For this reason and in an effort to better understand AhR signaling in meningioma, we analyzed benign intracranial meningiomas under hypoxic conditions such as preoperative endovascular embolization and under mimetic-induced hypoxia in short-term tumor cell culture to investigate the putative crosstalk between AhR and hypoxia pathways. The gene discussed is AHR; the disease is intracranial meningioma.
