An in vitro investigation demonstrated that GA in both human glioma U251n and U87 cells inhibited glioma cell proliferation, viability, and invasiveness, as well as tube development in normal mouse brain endothelial cells, and it inhibited ADAM17 expression, which may be linked to the suppression of invasiveness through the deactivation of Ras/MAPK and PI3K/Akt signaling pathways [98]. The gene discussed is ADAM17; the disease is central nervous system cancer.
