Our recent studies have indicated that acetylcholine (ACh) protects cardiomyocytes from prolonged hypoxia through activation of the PI3K/Akt/HIF-1alpha/VEGF pathway and that cardiomyocyte-derived VEGF promotes angiogenesis in a paracrine fashion.
ACh and nicotine upregulated signal transduction with acceleration of tube formation, suggesting that donepezil promotes a common angiogenesis pathway.

These results suggest that nicotine as well as AChE inhibitors, donepezil and galantamine, prevent glutamate neurotoxicity through alpha4 and alpha7 nAChRs and the PI3K-Akt pathway.
