Study of the therapeutic effect of 188Re labeled folate targeting albumin nanoparticle coupled with cis-Diamminedichloroplatinum Cisplatin on human ovarian cancer

摘要

This paper aimed to investigate the treatment efficiency of 188Re labeled folate targeting albumin nanoparticles with cis-Diamminedichloroplatinum Cisplatin (188Re-folate-CDDP/HAS MNP) on human ovarian cancer. SKOV3 cells or tumor-bearing mice were divided into different groups and treated as follow: (A) negative control; (B) chemotherapy; (C) radiotherapy; (D) hyperthermia; (E) chemotherapy and radiotherapy; (F) chemotherapy and hyperthermia; (G) radiotherapy and hyperthermia; (H) chemotherapy, radiotherapy and hyperthermia. Treatment of B to H inhibited proliferation of SKOV3 cells, with the greatest inhibition being observed in group H (P0.05). Obvious apoptotic hypodiploid peak appeared beside G1 phase in groups of B to H. The apoptotic rates of SKOV3 cells in groups of A to H were 0.08%, 7.56%, 8.64%, 17.14%, 21.64%, 23.77%, 33.94% and 57.16%, respectively. Our findings in vivo study showed that the mass of tumor in each group of B to H was significantly lower than that in the negative control (p 0.05). In addition, compared with each group of B to G, group H showed highest inhibition of tumor growth (p0.05). In conclusion, the combination of magnetic induced hyperthermia, chemotherapy and targeted radionuclide of radiation exposure can effectively inhibit the growth of ovarian cancer, which indicates a potential applications in ovarian cancer treatment.
