Abstract:
OBJECTIVETo study the inhibition effect of taspine on mouse S180 sarcoma and its mechanism.
METHODThe mouse S180 sarcoma model was established and used to observe the antitumor activity of taspine. The microvessel density and protein expressing of the VEGF, bFGF, Bcl-2 and Bax in the tumor were measured by immunohistochemistry.
RESULTTaspine showed antitumor activity on the mouse S180 sarcoma in a good dose-dependent manner. The inhibition rates on tumor of taspine at low, middle and high concentrations were 39.08% , 43.99% and 48.60%, respectively. The microvessel density and protein expressing of the VEGF, bFGF, Bcl-2 and Bax in the tumor were decreased compared with the negative control. The ratio of Bax to Bcl-2 was increased.
CONCLUSIONTaspine has antitumor effect on the S180 sarcoma, and the mechanism may be through the way of decreasing the expressing of the VEGF, bFGF, Bcl-2 and Bax and inducing the vascular endothelial cell apoptosis.
