ABSTRACT
Objective To evaluate the inhibitory effect of endostatin on bladder tumor and to investigate the possible mechanism of the inhibition. Methods (1)By means of MTT method,the effects of endostatin on ECV304 and EJ cells proliferation were studied.(2)Ten nude mice were subcutaneously implanted with EJ bladder tumor cells (1?10 7/ml). After the tumor volume exceeded 100~200 mm 3,the mice were randomized into two groups.One group received recombinant human endostatin (2 mg?kg -1 ?d -1 ) whereas the other group received PBS as control.All the treatment lasted 21 days.(3) After that,the mice were sacrificed and then MMPs and TIMPs mRNA expression were measured in implanted tumor by RT PCR and Western blot method. Results (1)Endostatin inhibits ECV304 proliferation stimulated with bFGF (5 ng/ml).In addition,we report for the first time that endostatin also inhibits EJ cells proliferation.(2)The mean tumor weight of endostatin treated group (0.70?0.16 g) was significantly lower than that of control group (1.14?0.21)g, P
