Abstract:
Objective RhuPAa-melittin protein with high-purity was analyzed to investigate its biologic effect on normal and ovarian cancer cells.Methods Preliminary purified rhuPAa-melittin was added in medium normal cells and SKOV3 human ovarian cancer cells cultured for 48 hours,and then were measured at 490 nm wavelength absorbance to measure the number of living cells and evalu-ate the inhibitory effect of rhuPAa-melittin on cultured cells.Results The inhibitory rate of rhuPAa-melittin at 4 μg/mL was 66.59% in SKOV3 cancer cell progression.At a concentration of 16 μg/mL, rhuPAa-melittin killed all cancer cells (P <0.05).In normal adult fibrous cells,the inhibitory rate of rhuPAa-melittin at 4 μg /mL was only 7.3%,and 12.3% inhibition rate was obtained by using rhu-PAa-melittin (8 μg/mL).Moreover,inhibition rate topped at 22.0% when used rhuPAa-melittin at 16 μg/mL.Conclusion RhuPAa-melittin has a strong anti-tumor effect on SKOV3 cancer cells.
