Effect and mechanism of Solanine on proliferation and apoptosis of Jurkat cells / 中华实用儿科临床杂志

ABSTRACT

Objective To explore the effect of proliferation and apoptosis of Solanine on acute T lymphocyte leukemia (T-ALL) Jurkat cells and its mechanism.Methods After treated with different concentrations of Solanine,the proliferation of Jurkat cells was detected by CCK-8 assay,and the effect of Solanine on apoptosis of Jurkat cells were detected by flow cytometry.The expression of Bcl-2 and Bax in Jurkat cells were detected by Western blot,and the expression levels of Bcl-2 mRNA and Bax mRNA were detected by real-time fluorescence quantitative polymerase chain reaction.Results CCK-8 assay showed that Solanine significantly inhibited the proliferation of Jurkat cells in a dose-and time-dependent manner.The results of flow cytometry showed that the apoptosis rates of Jurkat cells treated with Solanine for 24 h were (2.40-± 0.98) ％,(28.43-± 4.86) ％,(41.56-± 1.87) ％,respectively,in a dose-dependent manner.Western blot showed that Solanine could increase the expression of Bax and decrease the expression of Bcl-2 in Jurkat cells,and they all were dose-dependent.Conclusion Solanine can significantly inhibit the proliferation and induce apoptosis of Jurkat cells.The mechanism is related to the up-regulation of Bax expression and down-regulation of Bcl-2 expression.
