3种活血化瘀中药复方含药血清对神经胶质瘤U251细胞JAK/STAT信号通路的影响
Effects of 3 Kinds of Serum Containning Blood-activating and Stasis-eliminating TCM Compound Formu-las on JAK/STAT Signal Pathway of Glioma U251 Cells
摘要
Abstract
OBJECTIVE:To evaluate the effects of 3 kinds of serum containing blood-activating and stasis-eliminating TCM compound formulas on aggressive behavior,Janus kinase (JAK)/signal transduction and transcriptional activator (STAT) pathway of glioma U251 cells. METHODS:Rats were randomly divided into normal saline group (5 mL/kg),Taohong Siwu decoction group(5.7 g/kg),Xuefu Zhuyu decoction(8.5 g/kg)and Didang decoction(2.8 g/kg),calculated by crude drug,intragastrically administrated once a day,for 10 d. 10% drug-containing serum culture medium was prepared after 2 h of last administration. After 10% drug-containing serum culture medium intervening U251 cells for 1 week,Transwell method was conducted to detect the cell invasion rate, Western blot was adopted to detect the metal matrix protease 2 (MMP-2), MMP-9, phosphorylated JAK2 (p-JAK2),phosphorylated STAT3(p-STAT3)protein expression;and real-time fluorescence quantitative polymerase chain reaction method was used to detect MMP-2,MMP-9 mRNA expression. RESULTS:Compared with blank serum,Xuefu Zhuyu decoction drug-containing serum can reduce cell invasion rate (P<0.05),decrease the MMP-2,MMP-9 mRNA and its protein expression, and p-JAK2,p-STAT3 protein expression in cells (P<0.05 or P<0.01),while there was no significant difference in above-men-tioned indexes in Taohong Siwu decoction drug-containing serum group and Didang drug-containing serum group(P>0.05). CON-CLUSIONS:In the 3 kinds of blood-activating and stasis-eliminating TCM compound formulas,Xuefu Zhuyu decoction shows sig-nificant invasive effect on inhibiting U251 cells;the mechanism may be related to inhibiting the activation of JAK2/STAT3 signal pathway and decreasing MMP-2,MMP-9 gene and protein expressions.关键词
