In Vitro	Neamine (0.625-25 μM; 48 hours; AsPC-1 cells) treatment inhibits ANG-mediated AsPC-1 cell proliferation in a dose-dependent manner in the range of 0.625-25 μM[1]. Neamine (100 μM) also blocks the nuclear translocation of ANG effectively[1]. Cell Proliferation Assay[1] Cell Line: AsPC-1 cells Concentration: 0.625 µM, 1.25 µM, 2.5 µM, 5 µM, 10 µM, 25 µM Incubation Time: 48 hours Result: Inhibited angiogenin (ANG)-induced AsPC-1 cells proliferation.
In Vivo	Neamine (30-60 mg/kg; subcutaneous injection; daily; for 14 days; male Balb/c nude mice) has anti-tumor effects on AsPC-1 xenograft models. Neamine reduces the expression levels of ANG, Ki-67 and CD31 in tumor xenografts[1]. Animal Model: Male Balb/c nude mice (4 weeks old) injected with AsPC-1 cells[1] Dosage: 30 mg/kg, 60 mg/kg Administration: Subcutaneous injection; daily; for 14 days Result: Had anti-tumor effects on AsPC-1 xenograft models.
