Objective

To investigate the effect of epifriedelanol (Epi) on gene expression of P-glycoprotein (P-gp) in human colorectal adenocarcinoma cell line LS174T and its mechanism.

Methods

LS174T cells were divided into control group and experimental -L, -M, -H groups. Experimental -L, -M, -H groups were treated with 5, 10, 20 μmol·L-1 Epi, respectively. Control group was treated with 0.1% dimethyl sulfoxide. Polymerase chain reaction was used to detect the mRNA expression level of P-gp. The effect of Epi on multidrug resistance protein 1 (MDR1/P-gp) luciferase activity was investigated by pregnane X receptor (PXR)-MDR1/P-gp dual luciferase reporter gene assay. In addition, Western Blot was used to detect the protein expression level of P-gp and the nuclear factor-κB (NF-κB) pathway related proteins.

Results

The relative expression levels of P-gp mRNA in experimental -M, -H groups and control group were 52.24±5.19, 23.00±3.52 and 100.00±9.00; the relative expression levels of P-gp protein were 86.37±9.96, 74.85±15.92 and 100.00±12.91; the relative activities P-gp luciferase were 230.19±41.32, 203.10±52.84 and 279.67±19.20; the relative expression levels of p65 (RelA/p65) in nucleus were 132.36±23.93, 145.96±25.15 and 100.00±10.88; the relative expression levels of phosphorylation NF-κB inhibits protein kinase α/β (p-IKKα/β) in cytoplasm were 184.00±54.82, 290.10±49.59 and 100.00±15.34; the relative expression levels of phosphorylated NF-κB inhibitory protein α (p-IκBα) in cytoplasm were 125.73±18.77, 133.69±20.25 and 100.00±8.12; the relative expression levels of IκBα in cytoplasm were 78.36±14.83, 70.44±14.57 and 100.00±22.82, respectively. The above indexes of experimental -M and experimental -H groups were compared with control group, and the differences were statistically significant (P<0.05, P<0.01, P<0.001).

Conclusion

Epi can down-regulate the gene expression of P-gp in human colorectal adenocarcinoma cell line LS174T, and the mechanism may be related to activation of NF-κB and suppression of PXR.

目的

研究表木栓醇(Epi)对人结肠腺癌细胞LS174T中P-糖蛋白(P-gp)基因表达的影响及机制。

方法

将LS174T细胞分为对照组和低、中、高剂量实验组。低、中、高剂量实验组分别用5、10、20 μmol·L-1 Epi处理细胞;对照组用0.1%二甲基亚砜处理细胞。用聚合酶链反应检测Epi对LS174T细胞中P-gp mRNA表达水平的影响,用孕烷X受体(PXR)-多药耐药蛋白1(MDR1/P-gp)双荧光报告基因实验检测Epi对LS174T细胞中MDR1(P-gp)荧光素酶活性的影响,用蛋白质印迹法检测Epi对LS174T细胞中P-gp及核因子-κB(NF-κB)通路相关蛋白表达水平的影响。

结果

中、高剂量实验组和对照组的P-gp mRNA相对表达水平分别为52.24±5.19、23.00±3.52和100.00±9.00,P-gp蛋白相对表达水平分别为86.37±9.96、74.85±15.92和100.00±12.91,荧光素酶相对活性分别为230.19±41.32、203.10±52.84和279.67±19.20,细胞核内p65(RelA/p65)相对表达水平分别为132.36±23.93、145.96±25.15和100.00±10.88,细胞质中磷酸化NF-κB抑制蛋白激酶α/β(p-IKKα/β)相对表达水平分别为184.00±54.82、290.10±49.59和100.00±15.34,磷酸化NF-κB抑制蛋白α(p-IκBα)相对表达水平分别为125.73±18.77、133.69±20.25和100.00±8.12,IκBα相对表达水平分别为78.36±14.83、70.44±14.57和100.00±22.82。中、高剂量实验组的上述指标与对照组比较,在统计学上差异均有统计学意义(P<0.05,P<0.01,P<0.001)。

结论

Epi可以抑制人结肠腺癌细胞LS174T中P-gp的基因表达,其机制可能与激活NF-κB通路和抑制PXR途径有关。

研究表木栓醇(Epi)对人结肠腺癌细胞LS174T中P-糖蛋白(P-gp)基因表达的影响及机制。

方法

将LS174T细胞分为对照组和低、中、高剂量实验组。低、中、高剂量实验组分别用5、10、20 μmol·L-1 Epi处理细胞;对照组用0.1%二甲基亚砜处理细胞。用聚合酶链反应检测Epi对LS174T细胞中P-gp mRNA表达水平的影响,用孕烷X受体(PXR)-多药耐药蛋白1(MDR1/P-gp)双荧光报告基因实验检测Epi对LS174T细胞中MDR1(P-gp)荧光素酶活性的影响,用蛋白质印迹法检测Epi对LS174T细胞中P-gp及核因子-κB(NF-κB)通路相关蛋白表达水平的影响。

结果

中、高剂量实验组和对照组的P-gp mRNA相对表达水平分别为52.24±5.19、23.00±3.52和100.00±9.00,P-gp蛋白相对表达水平分别为86.37±9.96、74.85±15.92和100.00±12.91,荧光素酶相对活性分别为230.19±41.32、203.10±52.84和279.67±19.20,细胞核内p65(RelA/p65)相对表达水平分别为132.36±23.93、145.96±25.15和100.00±10.88,细胞质中磷酸化NF-κB抑制蛋白激酶α/β(p-IKKα/β)相对表达水平分别为184.00±54.82、290.10±49.59和100.00±15.34,磷酸化NF-κB抑制蛋白α(p-IκBα)相对表达水平分别为125.73±18.77、133.69±20.25和100.00±8.12,IκBα相对表达水平分别为78.36±14.83、70.44±14.57和100.00±22.82。中、高剂量实验组的上述指标与对照组比较,在统计学上差异均有统计学意义(P<0.05,P<0.01,P<0.001)。

结论

Epi可以抑制人结肠腺癌细胞LS174T中P-gp的基因表达,其机制可能与激活NF-κB通路和抑制PXR途径有关。

Objective

To investigate the effect of epifriedelanol (Epi) on gene expression of P-glycoprotein (P-gp) in human colorectal adenocarcinoma cell line LS174T and its mechanism.

Methods

LS174T cells were divided into control group and experimental -L, -M, -H groups. Experimental -L, -M, -H groups were treated with 5, 10, 20 μmol·L-1 Epi, respectively. Control group was treated with 0.1% dimethyl sulfoxide. Polymerase chain reaction was used to detect the mRNA expression level of P-gp. The effect of Epi on multidrug resistance protein 1 (MDR1/P-gp) luciferase activity was investigated by pregnane X receptor (PXR)-MDR1/P-gp dual luciferase reporter gene assay. In addition, Western Blot was used to detect the protein expression level of P-gp and the nuclear factor-κB (NF-κB) pathway related proteins.

Results

The relative expression levels of P-gp mRNA in experimental -M, -H groups and control group were 52.24±5.19, 23.00±3.52 and 100.00±9.00; the relative expression levels of P-gp protein were 86.37±9.96, 74.85±15.92 and 100.00±12.91; the relative activities P-gp luciferase were 230.19±41.32, 203.10±52.84 and 279.67±19.20; the relative expression levels of p65 (RelA/p65) in nucleus were 132.36±23.93, 145.96±25.15 and 100.00±10.88; the relative expression levels of phosphorylation NF-κB inhibits protein kinase α/β (p-IKKα/β) in cytoplasm were 184.00±54.82, 290.10±49.59 and 100.00±15.34; the relative expression levels of phosphorylated NF-κB inhibitory protein α (p-IκBα) in cytoplasm were 125.73±18.77, 133.69±20.25 and 100.00±8.12; the relative expression levels of IκBα in cytoplasm were 78.36±14.83, 70.44±14.57 and 100.00±22.82, respectively. The above indexes of experimental -M and experimental -H groups were compared with control group, and the differences were statistically significant (P<0.05, P<0.01, P<0.001).

Conclusion

Epi can down-regulate the gene expression of P-gp in human colorectal adenocarcinoma cell line LS174T, and the mechanism may be related to activation of NF-κB and suppression of PXR.
