The protective effects of liraglutide against Aβ-induced neurotoxicity in neuroblastoma cells are attributed to the activation of the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway, as evidenced by the increased phosphorylation of Akt and the altered expression of the apoptosis-related proteins Bcl-2/Bax, and cytochrome c [49]. The gene discussed is AKT1; the disease is neuroblastoma.
