目的
2
探讨白头翁汤水煎液通过调控经典Hedgehog(Hh)信号通路诱导人结直肠癌细胞HCT116凋亡的作用及其机制。
方法
2
用白头翁汤(25、50、100、200、500、750、1 000 mg·L
-1
)处理HCT116细胞24 h,然后用噻唑蓝(MTT)比色法检测白头翁汤对细胞增殖的影响;分别设置空白组、白头翁汤组(125、250、500 mg·L
-1
)和五氟尿嘧啶(5-FU)组(40 mmol·L
-1
),显微镜观察细胞给药前后形态变化;划痕实验检测白头翁汤对细胞迁移的影响;Hoechest 33324/碘化丙锭(PI)染色法评价白头翁汤对细胞凋亡的影响;流式细胞术检测白头翁汤对HCT116细胞凋亡的影响;蛋白免疫印迹法(Western blot)检测细胞凋亡相关B细胞淋巴瘤-2(Bcl-2)、Bcl-2相关X蛋白(Bax)的表达水平及Hh信号通路关键因子音猬因子(SHh)、GLI家族锌指蛋白1(Gli1)、G蛋白偶联受体蛋白Smoothened(Smo)、苏氨酸蛋白激酶Fused抑制因子(SuFu)、c-核蛋白类基因(c-Myc)蛋白表达水平;实时荧光定量聚合酶链式反应(Real-time PCR)检测凋亡相关基因Bax、Bcl-2和Hh通路相关基因SHh、Gli1、Smo、SuFu、c-Myc mRNA表达水平。
结果
2
与空白组比较,白头翁汤组(125、250、500 mg·L
-1
)HCT116细胞形态发生明显改变,细胞变圆,其增殖被抑制,且呈浓度依赖性,迁移能力下降(
P
<
0.05,
P
<
0.01),细胞核出现致密浓染,凋亡数量增加。与空白组比较,白头翁汤(500 mg·L
-1
)处理HCT116细胞24 h,Bax蛋白和mRNA表达水平升高(
P
<
0.05,
P
<
0.01),Bcl-2蛋白和mRNA表达水平降低(
P
<
0.05,
P
<
0.01)。与空白组比较,白头翁汤组(500 mg·L
-1
)处理24 h后,Hh信号通路关键因子SHh、Gli1、Smo、c-Myc的mRNA和蛋白水平表达降低(
P
<
0.05,
P
<
0.01),Hh信号通路负调控因子SuFu表达水平升高(

0.01)。
结论
2
白头翁汤通过降低Hh信号通路活性来抑制结直肠癌细胞HCT116增殖和迁移,诱导癌细胞凋亡。
Objective
2
To explore the effect of Baitouweng Tang (BTWT) on the apoptosis of human colorectal cancer HCT116 cells and decipher the underlying mechanism based on the Hedgehog (Hh) signaling pathway.
Method
2
HCT116 cells were treated with BTWT (25, 50, 100, 200, 500, 750, and 1 000 mg·L
-1
) for 24 h, and then the cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) colorimetry. Five groups were designed for the treatment of HCT116 cells, including a blank control group, BTWT groups (125, 250, and 500 mg·L
-1
), and a positive control (5-fluorouracil, 5-FU, 40 mmol·L
-1
) group. The cell morphology was observed under an inverted microscope. The migration of the cells was detected by scratch test, and the apoptosis by Hoechest 33324/propidium iodide (PI) staining and flow cytometry. Western blot was employed to determine the protein levels of sonic hedgehog (SHh), GLI family zinc finger protein 1 (Gli1), smoothened (Smo), suppressor of fused (SuFu), cellular-myelocytomatosis viral oncogene (c-Myc), and the apoptosis-related proteins B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax). The quantitative real-time reverse transcription PCR (Real-time PCR) was employed to determine the mRNA levels of Bax, Bcl-2, SHh, Gli1, Smo, SuFu, and c-Myc.
Result
2
Compared with the blank control group, BTWT changed the cell morphology (making the cell become round with dense nucleus), inhibited the proliferation of HCT116 cells in a dose-dependent manner, decreased the ability of migration (
P
<
0.05,
P
<
0.01), and increased apoptotic cells. Compared with the blank control group, BTWT (500 mg·L
-1
) treatment for 24 h up-regulated the protein and mRNA levels of Bax (
P
<
0.05,
P
<
0.01) and down-regulated the protein and mRNA levels of Bcl-2 in HCT116 cells (
P
<
0.05,
P
<
0.01). Moreover, the treatment down-regulated the mRNA and protein levels of SHh, Gli1, Smo, and c-Myc (
P
<
0.05,
P
<
0.01) and up-regulated the mRNA and protein levels of SuFu (
P
<
0.05,
P
<
0.01).
Conclusion
2
BTWT inhibited the proliferation and migration and induced the apoptosis of colorectal cancer HCT116 cells by down-regulating the Hh signaling pathway.
