Synergistic effects of verapamil on pingyangmycin-induced cytotoxicity and apoptosis in KB cells

OBJECTIVES: Previous studies have shown that pingyangmycin (PYM; bleomycin A5) can induce two distinct modes of cell death (necrosis, apoptosis). At high concentrations, PYM can be considered as an apoptosis mimetic drug. In this study, we explored the possibility that the membrane-modifying agent verapamil might affect the transport function of PYM through the plasma membrane, resulting in inducing apoptosis of tumor cells at low concentration of PYM. METHODS: Cytotoxicity, flow cytometry and DNA fragmentation assays were used to detect the interaction of verapamil and PYM in human oral carcinoma cell line KB cells. RESULTS: Our results indicated that verapamil can enhance the cytotoxicity of PYM against KB cells with the non-toxic doses (P<0.05). The cell viability at a concentration of 500 microg ml-1 of PYM was 35+/-2% compared with control and 10 microg ml-1 verapamil decreased the cell viability lower to 28+/-1%. In addition, because of the synergistic effect of verapamil, KB cells apoptosis was found to be induced when treated with a lower concentration of PYM (50 microg ml-1) for 24 h by flow cytometry and DNA fragmentation assays. CONCLUSIONS: Verapamil was found to enhance PYM-induced cytotoxicity and apoptosis in KB cells. The responsiveness of PYM might be explained by the effective accumulation of PYM by verapamil in KB cells mediated by the inhibition of PYM efflux function of the cells.

Superselective uterine arterial embolization with pingyangmycin-lipiodol emulsion for management of symptomatic uterine leiomyoma

Background Uterine arterial embolization (UAE) is a safe and effective therapy for symptomatic uterine leiomyoma. This study was to assess the effectiveness and the feasibility of pingyangmycinlipiodol emulsion (PLE) for the management of symptomatic uterine leiomyoma.Methods One hundred consecutive patients (aged 21-53 years, with 38 in average ) with symptomatic uterine leiomyoma underwent superselective UAE with PLE. Clinical symptoms of the patients (including menorrhagia, bulk-related symptoms, and postprocedure-related abdominal pain) and the changes in uterine volume and tumor size after the embolization were analyzed. The patients were followed up for 8-21 months (mean, 15 months).Results Ninety-nine patients (99%,99/100) were interviewed in their first menses circle after embolization, showing improvements in their abnormal bleeding and bulk-related symptoms to some extent. Imagiological results during follow-up showed a mean of 48% reduction in uterine volume at 6 months and a mean of 75% reduction in tumor size at 9 months. Eighty-three percent of the patients reported complete resolution of postprocedure pain within 7 days.Conclusions PLE is effective in the management of uterine leiomyoma, having superiority in alleviating postprocedure-related pain.
