摘 要 目的:研究溴苯基姜黄素(GL63)对人胆管癌RBE细胞凋亡、迁移和侵袭的影响,并基于Janus激酶(JAK)/信号转导及转
录激活因子(STAT)信号通路探讨其作用机制。方法:采用MTT法检测不同浓度GL63[0(空白对照,下同)、1.25、2.5、5、10、20、40
μmol/L]作用48 h对RBE细胞增殖的影响,并计算其半数抑制浓度(IC50 );采用结晶紫染色法检测不同浓度GL63(0、5、10、20 μmol/L)
作用48 h对细胞集落形成的影响;分别采用流式细胞术、Hoechst 33342染色法、细胞划痕实验、Transwell小室侵袭实验检测不同
浓度GL63(0、5、10、20 μmol/L)作用24 h对细胞周期分布、凋亡情况以及细胞迁移和侵袭能力的影响;采用Western blotting法检测
不同浓度GL63(0、5、10、20 μmol/L)作用24 h对细胞中JAK2/STAT3信号通路肿瘤相关蛋白表达的影响。结果:不同浓度GL63组
(1.25~40 μmol/L)RBE细胞的增殖抑制率均较空白对照组显著升高(P<0.01),并呈剂量依赖趋势;其IC50为(8.46±1.30)μmol/L。
与空白对照组比较,不同浓度GL63组(5、10、20 μmol/L)RBE细胞的集落形成抑制率均显著降低(P<0.01);G0/G1期细胞占比均显
著升高,S 期细胞占比均显著降低(P<0.01);细胞凋亡率均显著升高(P<0.01),且细胞核呈浓染致密的固缩形态并可见凋亡小
体;细胞迁移愈合率均显著降低(P<0.01),穿过基底膜的侵袭细胞数均显著减少(P<0.01);细胞中磷酸化JAK2、磷酸化STAT3、
B 淋巴细胞瘤-2(Bcl-2)、基质金属蛋白酶 2(MMP-2)、MMP-9、前体胱天蛋白酶 9(Pro-caspase-9)、Pro-caspase-3 蛋白表达水平
均显著降低,Bcl-2 相关 x 蛋白(Bax)、细胞色素 C、裂解 Caspase-9(Cleaved-caspase-9)、Cleaved-caspase-3 蛋白表达水平均显著升
高(P<0.01)。结论:GL63 能通过抑制 JAK2/STAT3 信号通路来实现对人胆管癌 RBE 细胞增殖、迁移和侵袭的抑制并诱导其
发生凋亡。

ABSTRACT OBJECTIVE:To study the effects of bromophenylcurcumin(GL63)on the apoptosis,migration and invasion of
human cholangiocarcinoma RBE cells,and to investigate its mechanism based on JAK/STAT signaling pathway. METHODS:MTT
assay was used to detect the effects of different concentrations of GL63 [0(blank control,similarly hereinafter),1.25,2.5,5,10,
20,40 μ mol/L] on the proliferation of RBE cells after 48 h treatment;the IC50 was calculated. The effects of different
concentrations of GL63(0,5,10,20 μmol/L)on colony formation were detected by crystal violet staining after 48 h treatment.
Flow cytometry,Hoechst 33342 staining,cell scratch test and Transwell chamber invasion test were used to detect the effects of
different concentrations of GL63(0,5,10,20 μmol/L)on cell cycle distribution,apoptosis,migration and invasion ability after
24 h treatment. Western blotting assay was adopted to detect the effects of different concentration of GL63(0,5,10,20 μmol/L)
on the expression of JAK2/STAT3 signal pathway associated proteins. RESULTS:The proliferation inhibition rates of RBE cells in
different concentrations of GL63 groups(1.25-40 μmol/L)were significantly increased,compared with blank control group (P<
0.01), and showed a dose-dependent trend, with IC50 of
