Ursolic acid effects proliferation、apoptosis and MYCN expression of neuroblastoma cell
- Keywords:
- Neuroblastoma; Ursolic acid; Cell proliferation; Cell apoptosis; MYCN
- Abstract:
- Objetive This study was designed to investigate the effects of ursolic acid in proliferation、apoptosis and MYCN gene mRNA expression of SHSY5Y cell line cultured in vitro, in order to investigate the effect of ursolic acid (UA) in neuroblastoma(NB).MethodNeuroblastoma SHSY5Y cells were treated by 4 uM/L、8 uM/L、12 uM/L ursolic acid.WST1 was used to measure the levels of the proliferation of SHSY5Ycells cultured with different concentrations of ursolic acid. While SHSY5Ycells apoptosis was measured by flow cytometry. MYCN gene mRNA expression in SHSY5Yceils was measured using real time PCR.ResultsThe proliferation of SHSY5Ycells was obviously inhibited by ursolic acid in a doseand timedependent manner. The apoptosis of SHSY5Ycells was obviously promoted by ursolic acid in a dosedependent manner. The MYCN gene mRNA expression in SHSY5Ycells was obviously inhibited by ursolic acid in a doseependent manner. Ursolic acid of 12uM/L treatment for 72 hrs produced a best effect with an inhibitory rate of SHSY5Y cell proliferation of 98.3 % and inhibitory rate of MYCN gene mRNA expression of 52.37%. ConclusionsUrsolic acid may inhibit the growth of neuroblastoma cells, promote neuroblastoma cells apoptosis and downregulate MYCN mRNA expression.
