目的:探讨胡黄连苷Ⅱ通过丝裂原活化的细胞外信号调节激酶(mitogen extracellular signal regulated kinase
MEK)/细胞外信号调节激酶(extracellular signal regulated kinase
ERK)通路抑制食管癌Eca109细胞增殖及侵袭转移的作用机制。方法:将人食管癌细胞Eca109分为正常培养组(常规培养)、胡黄连苷Ⅱ组(20μmol/L胡黄连苷Ⅱ)、激活剂组(20μmol/L MEK/ERK信号通路激活剂)以及胡黄连苷Ⅱ+激活剂组(20μmol/L胡黄连苷Ⅱ培养液+20μmol/L MEK/ERK信号通路激活剂)。以四唑盐法检测四组Eca109细胞增殖活性
以流式细胞仪检测四组Eca109细胞凋亡及周期情况
以Transwell小室、划痕实验检测细胞侵袭及迁移能力
以蛋白免疫印迹法检测细胞凋亡相关蛋白、周期相关蛋白以及MEK/ERK通路相关蛋白表达情况。结果:与正常培养组相比
胡黄连苷Ⅱ组细胞增殖抑制率、细胞凋亡率
Caspase-3、Bax蛋白表达
G0/G1期、S期比例升高; Bcl-2蛋白
G2/M期比例
侵袭细胞数、划痕愈合率
细胞周期相关蛋白、MEK/ERK通路相关蛋白表达降低
上述差异均有统计学意义(P <0.05)。与正常培养组相比
激活剂组细胞增殖抑制率、细胞凋亡率

可能通过抑制MEK/ERK通路相关蛋白的表达来发挥作用。
OBJECTIVE: To probe into the mechanism of picroside Ⅱ inhibiting proliferation
invasion and metastasis of esophageal cancer Eca109 cells through mitogen extracellular signal regulated kinase( MEK)/extracellular signal regulated kinase( ERK) pathway. METHODS: Human esophageal cancer cells Eca109 were divided into normal culture group( conventional culture)
picroside Ⅱ group( 20 μmol/L of picroside Ⅱ)
activator group( 20 μmol/L of MEK/ERK signaling pathway activator) and picroside Ⅱ + activator group( 20 μmol/L of picroside Ⅱ + 20 μmol/L of MEK/ERK signaling pathway activator). The proliferative activity of Eca109 cells in each group was detected by tetrazolium salt method
the apoptosis and cycle of Eca109 cells in each group were detected by flow cytometry
the cell invasive and metastasizing ability were detected by Transwell and scratch assay
the expression of apoptosis-related proteins
cycle-related proteins and MEK/ERK pathway-related proteins were detected by protein immunoblotting.RESULTS: Compared with the normal culture group
the inhibition rate of cell proliferation
apoptosis rate
Caspase-3 and Bax protein expression
G0/G1 phase and S phase ratio were increased in the picroside Ⅱ group; the Bcl-2 protein
G2/M phase ratio
invasion cell number
scratch healing rate
cell cycle-related proteins and MEK/ERK pathway-related proteins of picroside Ⅱ group were decreased
with statistically significant differences( P < 0. 05).Compared with the normal culture group
the inhibition rate of cell proliferation
apoptosis rate
Caspase-3 and Bax protein expression
G0/G1 phase and S phase ratio were decreased in the activator group; the Bcl-2 protein
G2/M phase ratio
invasion cell number
scratch healing rate
cell cycle-related proteins and MEK/ERK pathway-related proteins of the activator group were significantly increased
with statistically significant differences( P < 0. 05).Compared with the picroside Ⅱ group
the inhibition rate of cell proliferation
apoptosis rate
Caspase-3 and Bax protein expression
G0/G1 phase and S phase ratio were decreased in the picroside Ⅱ + activator group; the Bcl-2 protein
G2/M phase ratio
invasion cell number
scratch healing rate
cell cycle-related proteins and MEK/ERK pathway-related proteins of the picroside Ⅱ + activator group were significantly increased
with statistically significant differences( P < 0. 05). Compared with activator group
the inhibition rate of cell proliferation
apoptosis rate
Caspase-3 and Bax protein expression
G0/G1 phase and S phase ratio were increased in the picroside Ⅱ + activator group; the Bcl-2 protein
G2/M phase ratio
invasion cell number
scratch healing rate
cell cycle-related proteins and MEK/ERK pathway-related proteins of the picroside Ⅱ + activator group were significantly decreased
with statistically significant differences( P < 0. 05). CONCLUSIONS: picroside Ⅱ has a certain inhibitory effect on the proliferation
invasion and metastasis of esophageal cancer cells
probably through inhibiting the expression of MEK/ERK pathway-related proteins.
