1Anticancer activity of Δ^(9)-tetrahydrocannabinol and cannabinol in vitro and in human lung cancer xenograft显示文摘Objective:To investigate the effects of Δ^(9)-tetrahydrocannabinol,the principal psychoactive compound of Cannabis sativa,and cannabinol,a Δ^(9)-tetrahydrocannabinol degradative product,on human non-small cell lung cancer cells.Methods:Δ^(9)-Tetrahydrocannabinol and cannabinol were tested for anticancer activity in human non-small cell lung cancer(A549)cells.The effects on cell proliferation,apoptosis,and phosphorylation profiles were examined.The effects of Δ^(9)-tetrahydrocannabinol and cannabinol on tumor growth were also investigated using a xenograft nude mouse model.Apoptosis and targeted phosphorylation were verified by immunohistochemistry.Results:Δ^(9)-Tetrahydrocannabinol and cannabinol significantly inhibited cell proliferation and increased the number of apoptotic cells in a concentration-dependent manner.The Δ^(9)-tetrahydrocannabinol-and cannabinol-treated cells had lower levels of phosphorylated protein kinase B[AKT(S473)],glycogen synthase kinase 3 alpha/beta,and endothelial nitric oxide synthase compared to the controls.The study of xenograft mice revealed that tumors treated with 15 mg/kg Δ^(9)-tetrahydrocannabinol or 40 mg/kg cannabinol were significantly smaller than those of the control mice.The tumor progression rates in mice treated with 15 mg/kg Δ^(9)-tetrahydrocannabinol or 40 mg/kg cannabinol were significantly slower than in the control group.Conclusions:These findings indicate that Δ^(9)-tetrahydrocannabinol and cannabinol inhibit lung cancer cell growth by inhibiting AKT and its signaling pathways,which include glycogen synthase kinase 3 alpha/beta and endothelial nitric oxide synthase.Surang Leelawat Kawin Leelawat Thaniya Wannakup Worawan Saingam Nanthaphong Khamthong Fameera Madaka Athip Maha Patamaporn Pathompak Lukman Sueree Thanapat Songsak 2022Asian Pacific Journal of Tropical Biomedicine2022,12,8:0
