Abstract:
Objective To investigate the effects of genistein used alone and in combination with cisplatin on the treatment of human ovarian carcinoma transplanted subcutaneously in nude mice. Methods Nude mouse model of human ovarian carcinoma transplanted subcutaneously was established. A total of 30 mice were divided into 5 groups: control group (0 04% saline), genistein group (subcutaneous injection of genistein at 0 2 mg/kg and 0 4 mg/kg), cisplatin group (intravenous injection of cisplatin at 4 mg/kg), and genistein plus cisplatin group. The growth of the subcutaneously transplanted tumor and changes of mouse body weight in each group after treatment using different medication regimens were observed at 7, 14, 21, and 28 d. Histopathological examination was also conducted. Results Genistein (0 4 mg/kg) had significantly inhibitory effect on the transplanted xenograft growth in vivo . Tumor volume, tumor weight, and T/C ratio (mean volume of treated group/mean volume of control group) decreased. Significantly enlarged necrotic areas were found in genistein treated group. The weight loss of nude mice after treatment with genistein was not significantly different from in the control group. Conclusion Genistein has the inhibitory effect on the growth of human ovarian carcinoma transplanted subcutaneously in nude mice. Genistein (0 4 mg/kg) in combination with cisplatin (4 mg/kg) has a synergistic effect on xenograft of human ovarian cancer cell line SKOV 3 in nude mice. The results provide the evidence for the potential usefulness of genistein for the prevention and treatment of human ovarian carcinoma.
