目的
2
探讨迷迭香酸(RA)对喉鳞状细胞癌(LSCC)细胞增殖、迁移的影响,并分析其潜在机制。
方法
2
取对数生长期的Hep-2和TU686细胞,分为对照组(未处理的Hep-2和TU686细胞)、低剂量组(20 μmol/L的RA处理)、中剂量组(50 μmol/L的RA处理)、高剂量组(100 μmol/L的RA处理)、胰岛素生长因子1(IGF-1)组(10 nmol/mL IGF-1处理)、IGF-1+RA组(100 μmol/L的RA与10 nmol/mL IGF-1同时处理)。倒置显微镜观察各组Hep-2和TU686细胞形态;CCK-8法检测各组Hep-2和TU686细胞增殖能力;细胞划痕实验检测各组Hep-2和TU686细胞迁移能力;Western blot检测各组Hep-2和TU686细胞中Ki-67、MMP-2、MMP-9及PI3K/AKT/mTOR信号通路相关蛋白的表达。
结果
2
RA可显著抑制Hep-2和TU686细胞的增殖、迁移,降低Ki-67、MMP-2、MMP-9蛋白表达和p-PI3K/PI3K、p-AKT/AKT、p-mTOR/mTOR水平(
P
<
0.05);IGF-1可有效逆转RA对Hep-2和TU686细胞增殖、迁移以及PI3K/AKT/mTOR信号通路的抑制作用(
P
<
0.05)。
结论
2
RA可能通过PI3K/AKT/mTOR信号通路抑制LSCC细胞的增殖和迁移。
Objective
2
To investigate the effect of rosmarinic acid (RA) on the proliferation and migration of laryngeal squamous cell carcinoma (LSCC) cells, and analyze its underlying mechanism.
Methods
2
Hep-2 and TU686 cells in logarithmic growth phase were taken and divided into control group (untreated Hep-2 and TU686 cells),low-dose group (treated with 20 μmol/L RA),middle-dose group (treated with 50 μmol/L RA),high-dose group (treated with 100 μmol/L RA),insulin-like growth factor 1 (IGF-1) group (treated with 10 nmol/L IGF-1) and IGF-1+RA group (co-treated with 100 μmol/L RA and 10 nmol/mL IGF-1).Inverted microscope was used to observe the morphology of Hep-2 and TU686 cells in each group; CCK-8 method was used to detect the proliferation of Hep-2 and TU686 cells in each group; scratch wound healing assay was used to detect the migration ability of Hep-2 and TU686 cells in each group; Western blot was used to detect the expression of Ki-67, MMP-2, MMP-9 and PI3K/pAKT/mTOR signaling pathway-related proteins in Hep-2 and TU686 cells of each group.
Results
2
RA could significantly inhibit the proliferation and migration of Hep-2 and TU686 cells, reduce the protein expression of Ki-67, MMP-2, MMP-9 and the levels of p-PI3K/PI3K, p-AKT/AKT, and p-mTOR/mTOR (
P
<
0.05); IGF-1 could effectively reverse the inhibitory effect of RA on Hep-2 and TU686 cell proliferation, migration and PI3K/AKT/mTOR signaling pathway (
P
<
0.05).
Conclusion
2
RA may inhibit the proliferation and migration of LSCC cells through PI3K/AKT/mTOR signaling pathway.
