结果
2
与空白组比较,10%、15%、20%三物白散高剂量组含药血清可呈浓度-时间依赖性抑制SGC-7901细胞活性;与空白组比较,模型组细胞失去梭形形态,多数细胞变圆、变长;与模型组比较,各药物组细胞伪足减少,细胞变小且形态恢复正常;与空白组比较,模型组细胞迁移和侵袭能力增强(
P
<
0.01);与模型组比较,三物白散中、高剂量组处理SGC-7901细胞24 h后能显著抑制其迁移能力(
P
<
0.01);三物白散低、中、高剂量组处理SGC-7901细胞48 h后均能显著抑制其迁移能力(
P
<
0.01);与模型组比较,三物白散低、中、高组剂量组均能显著抑制其侵袭能力(
P
<
0.01);与空白组比较,模型组E-cadherin及Smad7蛋白的表达水平显著降低(
P
<
0.01),Snail、p-Smad3、TGF-
β
1
蛋白的表达水平显著升高(
P
<
0.01),Smad3总蛋白水平不变;与模型组比较,三物白散高剂量组E-cadherin蛋白显著增加(
P
<
0.01)、三物白散中剂量组有明显上升(

P
<
0.01)。三物白散含药血清可以有效地逆转TGF-
β
1
诱导的人胃癌SGC-7901细胞EMT,并可能通过TGF-
β
/Smad信号通路发挥作用。
结论
2
三物白散能抑制TGF-
β
1
诱导的SGC-7901细胞EMT的发生,其机制可能与调控TGF-
β
/Smad信号通路有关。
Objective
2
To study the effect of serum containing Sanwubai San on TGF-
β
1
induced epithelial mesenchymal transition (EMT) of human gastric cancer SGC-7901 cells and its mechanism
in vitro
based on transforming growth factor-
β
/Smad(TGF-
β
/Smad)signaling pathway.
Method
2
Twenty-eight male SD rats (SPF grade, three months) were randomly divided into blank group and Sanwubai low (0.031 25 g·kg
-1
·d
-1
,
ig
), medium (0.062 5 g·kg
-1
·d
-1
,
ig
) and high (0.125 g·kg
-1
·d
-1
,
ig
) dose groups, seven in each group. The blank group was given the same volume of ultrapure water (
ig
). The gavage was performed once a day for seven consecutive days. The serum containing the drug was taken from the abdominal aorta 45 min after the last administration. Cell counting kit-8 (CCK-8) method was used to detect the effect of serum in Sanwubai San high dose group on the activity of SGC-7901 cells. Changes of cell morphology after treatment with TGF-
β
1
and serum containing Sanwubai San were observed by microscopy, and the migration rate and invasion rate of the SGC-7901 cells were detected by cell scratch assay and transwell assay, respectively. Western blot was used to detect the expression of E-cadherin, snail, TGF-
β
1
, Smad3, p-Smad3 and Smad7 proteins.
Result
2
Compared with the blank group, 10%, 15% and 20% high-dose Sanwubai San inhibited the activity of SGC-7901 cells in a concentration and time dependent manner. Compared with the conditions in the blank group, the cells in the model group lost spindle shape, and most cells became round and long. Compared with the model group, the Sanwubai San groups had decreased pseudopodia and small cells with the morphology returning to normal. Compared with the conditions in the blank group, enhanced ability of cell migration and invasion (
P
<
0.01), lowered expression of E-cadherin and Smad7 (
P
<
0.01), and increased expression of Snail, p-Smad3 and TGF-
β
1
(
P
<
0.01) were found in the model group, with the total protein level of Smad3 remaining unchanged. Compared with the conditions in the model group, the cell migration ability was inhibited in the Sanwubai San high and medium dose groups (
P
<
0.01) after 24 h, and the ability was inhibited in all three Sanwubai San groups after 48 h (
P
<
0.01), while the invasion ability was enhanced. In addition, the Sanwubai San high and medium dose groups had elevated expression of E-cadherin (
P
<
0.01) and Smad7 (
P
<
0.01), and decreased expression of Snail (
P
<
0.01), and the expression of TGF-
β
1
and
p-Smad3 was down-regulated in the three Sanwubai San groups (
P
<
0.01).
Conclusion
2
Sanwubai San could inhibit TGF-
β
1
induced EMT in SGC-7901 cells, and its mechanism might be related to the regulation of TGF-
β
/Smad signaling pathway.
