摘要:

目的 探究阿魏酸钠调控 JAK2/STAT3 信号通路对胶质瘤细胞增殖、侵袭、凋亡的影响。 方法 胶质瘤细胞系 U251 经过培养、干预分为阿魏酸钠低浓度组、中浓度组、高浓度组和空白组、阴性对 照组。在培养 72 h 后观察细胞生物学行为,并检测细胞 JAK2/STAT3 通路蛋白表达情况。结果 阿魏酸 LC50 = 0.307 5 mg/mL,绘制量效关系曲线发现,在 10-3 ~ 1 mg/mL 对细胞增殖的抑制较为明显,结合药物 LC50,设定本次研究的阿魏酸钠高、中、低浓度分别为 0.3、0.03、0.003 mg/mL。与空白组相比,阳性对照 组、低、中、高浓度组增殖率、侵袭数、迁移率降低,凋亡率升高(P < 0.05);高浓度组增殖率、侵袭数、迁移 率降低明显,凋亡率升高明显(P < 0.05)。与空白组相比,阳性对照组、低、中、高浓度组 p⁃JAK2、p⁃STAT3 蛋白表达量降低(P < 0.05);高浓度组 p⁃JAK2、p⁃STAT3 蛋白表达量降低最为明显(P < 0.05)。结论 阿魏 酸钠可明显抑制胶质瘤细胞增殖、迁移、侵袭,促进凋亡,其发挥作用的机制可能与诱导 JAK2/STAT3 通路 失活相关。

Abstract:

Objective To explore the effect of sodium ferulate on the proliferation,invasion and apoptosis of glioma cellsby regulating JAK2/STAT3 signaling pathway. Methods After culture and intervention,the glioma cell line U251 was divided into low concentration group,medium concentration group,high concentration group blank group and negative control group. The biological behavior of the cells after 72 hours of culture was observed and the expression of JAK2/STAT3 pathway proteins in the cells was detected. Results After administration of Sodium ferulate(LC50 = 0.307 5 mg/mL),dose⁃effect relationship curve showed the inhibition of cell proliferation was more obvious at 10- 3 ~ 1 mg/mL. The high,medium,and low sodium concentrations were 0.3,0.03,and 0.003 mg/mL,respectively. Compared with the blank group,the proliferation rate,invasion number,and migra⁃ tion rate of the positive control group,low,medium,and high concentration groups were decreased,and the apop⁃ tosis rate was increased(P < 0.05);the proliferation rate,invasion number,and migration rate was decreased in the high concentration group. Obviously,the apoptotic rate increased significantly(P < 0.05). Compared with the blank group,the expression of p⁃JAK2 and p⁃STAT3 protein in the positive control group,low,medium,and high concentration groups were decreased(P < 0.05);the expression of p⁃JAK2 and p⁃STAT3 protein in the high concentration group were decreased most significantly(P < 0.05). Conclusion Sodium ferulate could significantly inhibit the proliferation,migration and invasion of glioma cells,and promote apoptosis. The mechanism of its action may be related to the inactivation of JAK2/STAT3 signaling pathway.
