目的
2
探讨中药黄芩苷对胃癌细胞HGC-27的作用及机制。
方法
2
CCK-8检测不同浓度黄芩苷对HGC-27细胞增殖的影响,并计算半数抑制浓度(IC50);流式细胞术检测黄芩苷对细胞凋亡的影响;细胞划痕实验评估黄芩苷对细胞迁移能力的影响;Western blot检测Wnt/β-catenin信号通路相关蛋白的表达变化。
结果
2
黄芩苷对HGC-27细胞的增殖具有显著的抑制作用,其IC50为104.1 μmol/L。75 μmol/L、100 μmol/L黄芩苷处理后细胞凋亡率高于0 μmol/L黄芩苷处理,差异有统计学意义(
P
<
0.05);75 μmol/L、100 μmol/L黄芩苷处理48 h细胞划痕愈合率低于0 μmol/L黄芩苷处理,差异有统计学意义(
P
<
0.05)。Western blot结果显示,75 μmol/L、100 μmol/L黄芩苷处理后细胞Wnt5a和β-catenin蛋白表达水平均显著下降(
P
<
0.05),而GSK3β蛋白表达水平明显升高(
P
<
0.05)。
结论
2
黄芩苷能够抑制胃癌细胞HGC-27的增殖、促进凋亡以及限制细胞迁移,可能通过调控Wnt/β-catenin信号通路实现其抗癌效应。
Objective
2
To investigate the effect of the traditional Chinese medicine baicalin on gastric cancer cells HGC-27 and its underlying mechanism.
Methods
2
The effects of various concentrations of baicalin on the proliferation of HGC-27 cells were detected by CCK-8 assay, and the half-maximal inhibitory concentration (IC50)was calculated. The effect of baicalin on cell apoptosis was determined by flow cytometry. The effect of baicalin on cell migration was evaluated by wound healing assay. The expression changes of proteins related to the Wnt/β-catenin signaling pathway were detected by Western blot.
Results
2
Baicalin significantly inhibited the proliferation of HGC-27 cells, exhibiting an IC50 of 104.1 μmol/L. Treatment with 75 or 100 μmol/L of baicalin increased the apoptosis rate of HGC-27 cells compared to treatment with 0 μmol/L of baicalin, with statistically significant differences(
P
<
0.05); the wound healing rate of HGC-27 cells treated with 75 μmol/L or 100 μmol/L of baicalin for 48 hours decreased compared to that treated with 0 μmol/L of baicalin, with statistically significant differences (
P
<
0.05). Western blot results showed that treatment with 75 μmol/L or 100 μmol/L of baicalin significantly downregulated the protein expression of Wnt5a and β-catenin in HGC-27 cells (
P
<
0.05), while upregulated the protein expression of GSK3β compare
d to treatment with 0 μmol/L of baicalin(
P
<
0.05).
Conclusion
2
Baicalin inhibits proliferation, promotes apoptosis, and suppresses migration of gastric cancer cells HGC-27. These anticancer effects are likely mediated through the regulation of Wnt/β-catenin signaling pathway.
