Mechanism study of the role of rhuPAa-melittin in ovarian cancer cells in vitro and in vivo / 实用医学杂志

ABSTRACT

Objective To investigate the role of the activated rhuPAa-melittin in ovarian cancer cells and to study the inhibitory effect of rhuPAa-melittinon on ovarian cancer cells. Methods rhuPAa-melittin was used to treat the ovarian cancer cells at different concentrations for 48 hrs. Then flow cytometery was applied to detect the cell cycle and cell apoptosis. rhuPAa-melittin protein was delivered to the mouse mode to investigate the effect of rhuPAa-melittin on the growth of the xenotransplanted tumor. Results rhuPAa-melittin was used to treat ovarian cancer cells at the concentration of 0 ,4 ,8 and 16 μg/mL for 48 hrs ,respectively. The results of cell apoptosis assay was 1.16%,3.83%,6.51% and 10.2%,respectively. Moreover,different concentrations of rhuPAa-melittin had no effects on the cells at G0/G1 phase,rhuPAa-melittin inhibited S phase cells to process into G2/M phase, contributing to suppressing the growth of ovarian cancer cells. Conclusion The in vivo and in vitro studies revealed that rhuPAa-melittin inhibits the growth of ovarian cancer.
