Abstract:

Harmine hydrochloride (Har-hc), a derivative from Harmine which is a natural extractive from plants, has been considered for treatment of kinds of cancers and cerebral diseases. In this study, we found that Har-hc clearly decreased cell viability, induced apoptosis and inhibited Akt phosphorylation in glioblastoma cell lines. Moreover, Har-hc had the ability to inhibit self-renewal and promote differentiation of glioblastoma stem like cells (GSLCs) accompanied by inhibition of Akt phosphorylation. Especially, we demonstrated that Har-hc inhibited neurosphere formation of human primary GSLCs. In vivo test also confirmed Har-hc decreased the tumorigenicity of GSLCs. Thus we conclude that Har-hc has potent anti-cancer effects in glioblastoma cells, which is at least partially via inhibition of Akt phosphorylation. Administration of Har-hc may act as a new approach to glioblastoma treatment.
