Reactive oxygen species(ROS) involving in inhibiting proliferation of human bone marrow neuroblastoma cells (SH-SY5Y) by giant typhonium rhizome water extract / 国际中医中药杂志

ABSTRACT

ObjectiveTo investigate whether the reactive oxygen species involved in inhibiting proliferation of human bone marrow cells of neuroblastoma cells (SH-SY5Y)process by giant typhonium rhizome water extract,and to investigate the initial mechanism of anti-tumor effect of giant typhonium rhizome in vitro.MethodsAfter giant typhonium rhizome water extract processing of human bone marrow neuroblastoma cells (SH-SY5Y)at 24 h and 48 h,the cells were collected,and western blotting reaction methods such as flow cytometry was used to study the levels of ROS and SH-SY5Y apoptosis.ResultsThe levels of ROS elevated from before dosing (4.9±1.6)％ to (39.7 ± 11.8)％ in the process of giant typhonium rhizome water extract induced apoptosis in SH-SY5Y; after ROS inhibition was added,SH-SY5Y apoptosis level induced by giant typhonium rhizome water extract had decreased.ConclusionROS involved in the process of giant typhonium rhizome water extract inhibiting cell proliferation in SH-SY5Y.
