摘要:
目的：探讨氯化锂对人肺腺癌A549细胞增殖和侵袭转移能力的影响及其调控机制。方法：应用MTT法、平板克隆增殖实验评价细胞生长活力和增殖的生物学特征变化；划痕实验、Transwell小室细胞体外侵袭实验检测肿瘤细胞迁移、侵袭能力；Western-blotting法检测肿瘤细胞GSK-3b、P-GSK-3b和b-catenin的表达水平变化。结果：MTT法显示细胞分化增殖活力随氯化锂浓度的增加受到明显抑制，具有浓度依赖性变化。同时，随着检测时间的延长，在低浓度药物作用下（<10 mmol/L）细胞出现增殖强化现象，可能存在药物时间耐受；平板克隆增殖实验显示细胞增殖受到不同浓度氯化锂的抑制，增殖能力的变化亦具有氯化锂浓度依赖性；划痕实验、Transwell实验证实：氯化锂处理细胞后，细胞迁移、侵袭能力下降；Western-blotting法显示：氯化锂处理肺腺癌A549细胞后，GSK-3b总蛋白表达下降、P-GSK-3b表达增加,b-catenin总蛋白表达增多。结论：高浓度的氯化锂能够抑制肺腺癌A549细胞的增殖侵袭和迁移，氯化锂抑制肺腺癌A549细胞增殖侵袭和迁移可能是通过GSK-3b/b-catenin信号通路实现的。
Abstract:
Objective ：To investigate the impact of lithium chloride on the proliferation and invasion abilities of human lung cancer cell A549. Methods：Cell growth and proliferation were determined by MTT method and Colony Proliferation Assay. Migration and invasion abilities of human lung cancer cell A549 were detected by wound scratch assay and Transwell assay. The expression of GSK-3b (Glycogen synthase kinase-3b), P-GSK-3b (Phosphorylation-GSK-3b) and b-catenin of human lung cancer cell A549 were detected by western-blotting. Results： The proliferation of A549 was significantly decreased after treated with lithium chloride indicating a lithium chloride concentration-dependent manner. Meanwhile, with the extension of the detection time, enhanced cell proliferation phenomenon was observed at low concentrations (<10 mmol/L)， indicating a time-tolerance of the drug. The proliferation of A549 could also be inhibited by lithium chloride with a dose-dependent manner. The migration and invasion capabilities of A549 decreased after treated with lithium chloride. And It was also found that the expression of GSK-3b was decreased while the expression of P-GSK-3b and b-catenin were increased after lithium chloride treatment. Conclusion：High concentration of lithium choride could inhibit the proliferation and invasion of A549, and this may be acheived by GSK-3b/b-catenin signaling pathway.
