目的
2
防己黄芪汤对血管内皮生长因子(VEGF)诱导的人脐静脉内皮细胞(HUVECs)增殖、迁移、黏附、侵袭及管腔形成能力的作用。
方法
2
VEGF(20 μg·L
-1
)体外诱导HUVECs,加入不同质量浓度防己黄芪汤(0.25,0.5,1 g·L
-1
)作用后,分别采用噻唑蓝(MTT)比色法、划痕修复实验、转移小室(transwell)迁移、黏附、侵袭及管腔形成实验检测防己黄芪汤对VEGF诱导的HUVECs功能的影响。提取HUVECs中的蛋白,采用蛋白免疫印迹法(Western blot)检测磷酸化Janus激酶1(p-JAK1)的蛋白表达水平。
结果
2
与空白组比较,VEGF(20 μg·L
-1
)能显著增加HUVECs细胞的增殖、划痕修复,transwell迁移、黏附、侵袭及管腔形成的能力(
P
<
0.01);与VEGF组比较,防己黄芪汤(0.25,0.5,1 g·L
-1
)作用24 h对VEGF诱导的HUVECs增殖活性没有明显影响,作用24 h内能明显降低VEGF诱导升高的HUVECs划痕修复,transwell迁移、黏附、侵袭及管腔形成的能力(
P
<
0.05)。与空白组比较,VEGF能显著诱导p-JAK1在HUVECs中的异常升高(
P
<
0.01),防己黄芪汤(0.25,0.5,1 g·L
-1
)能明显降低p-JAK1的表达水平(
P
<
0.05,
P
<
0.01)。
结论
2
防己黄芪汤能够降低VEGF诱导的HUVECs划痕修复,transwell迁移、黏附、侵袭及管腔形成的能力,而其机制可能与JAK1相关。
Objective
2
To study the effects of Fangji Huangqitang(FJHQT) on migration, adhesion,invasion and tube formation of human umbilical vein endothelial cells (HUVECs) induced by vascular endothelial growth factor (VEGF).
Method
2
HUVECs were induced by VEGF (20 μg·L
-1
)
in vitro
. The effects of FJHQT (0.25,0.5,1 g·L
-1
) on HUVECs were detected by methyl thiazolyl tetrazolium(MTT), scratch repair, transwell migration, adhesion, invasion and tube formation. Protein in HUVECs was extracted and protein expression levels of phosphorylated Janus kinase 1 (p-JAK1) were detected by Western blot.
Result
2
Compared with control group, VEGF (20 μg·L
-1
) can increase the proliferation, scratch repair, transwell migration, adhesion, invasion and tube formation of HUVECs cells (
P
<
0.01), compared with VEGF group, FJHQT (0.25,0.5,1 g·L
-1
) ,there is no significant effect on the proliferation of HUVECs induced by VEGF for 24 hours, but it can significantly reduce the scratch repair, migration, adhesion, invasion and tube formation of HUVECs induced by VEGF within 24 hours (
P
<
0.05). Compared with blank group, VEGF could induce abnormal elevation of p-JAK1 in HUVECs (
P
<
0.01), while FJHQT (0.25,0.5,1 g·L
-1
) could significantly reduce the expression levels of p-JAK1 (
P
<
0.05,
P
<
0.01).
Conclusion
2
FJHQT can inhibit the migration, adhesion and invasion of HUVECs, the mechanism may be related to JAK1.
