Abstract: Objective To investigate the growth-inhibitory effect of sunitinib malate on human bladder transitional cell carcinoma (TCC) in vitro.
Methods Human bladder TCC cell line T24 was cultured and exposed to graded concentrations of sunitinib malate for 72 hours in vitro to determine the sensitivities to drug. Cell viability was measured by MTT assay. Cell apoptotic morphology was observed by fluorescence microscope following DAPI staining. Band expressions of Fas, Fas ligand, poly (ADP-ribose) polymerase (PARP) and β-actin were analyzed by Western blot. Wound healing process of T24 cells exposed to sunitinib malate was assayed.
Results Sunitinib malate exerted a concentration-dependent and time-dependent inhibitory effect on the T24 cell lines. Fluorescence microscopy showed that small vacuoles appeared in the nuclei of T24 cells and the vacuoles were bigger with higher drug concentrations. The expressions of Fas ligand and PARP in T24 cells treated with sunitinib malate exhibited a concentration-dependent increase. Moreover sunitinib malate suppressed the wound healing process in a concentration-dependent manner.
Conclusion Sunitinib malate exerted marked inhibitory activity against bladder cancer cell line T24.

Key words: sunitinib, bladder cancer, proliferation
