Objective

To investigate the effect of Huangqin Decoction(黄芩汤,HQD)on ferroptosis in ulcerative colitis based on kelch-like ECH-associated protein 1(Keap1)/nuclear factor-erythroid 2 related factor 2(Nrf2)pathway.

Methods

The mice in the in vivo experiment were divided into normal group,model group,traditional Chinese medicine group(HQD group)and mesalazine group. The ulcerative colitis mice were induced by dextran sulfate sodium. HE staining was used to observe the histo-pathology of colon. The contents of Fe in tissues were detected. The mRNA expression levels of glutathione peroxidase 4(GPX4),prostaglandin-endoperoxide synthase 2(PTGS2),Nrf2,Keap1 and heme oxygenase-1(HO-1)were detected by quantitative polymerase chain reaction(q-PCR). The cells in the vitro experiments were divided into normal group,model group,HQD group and inhibitor group(ML385),and the cell ferroptosis model was constructed with Erastin. The cell growth was detected by CCK-8. The contents of Fe and lactate dehydrogenase(LDH)were detected. The mRNA expression levels of GPX4,PTGS2,Nrf2,Keap1 and HO-1 were detected by q-PCR. The protein expression levels of GPX4,PTGS2,Nrf2,Keap1 and HO-1 were detected by Western Blot.

Results

In the in vivo experiments,compared with the model group,the HQD group and the mesalazine group obtained better results in ameliorating colon injury. In comparison to the model group,the Fe content was significantly decreased in the HQD group and the mesalazine group. In comparison to model group,the mRNA expression levels of PTGS2,HO-1,Nrf2 and Keap1 were decreased,the mRNA expression level of GPX4 was increased in both the HQD group and the mesalazine group. Compared with that of the model group,the cell vitality of the HQD group and the ML385 group were significantly increased. In comparison to the model group,the contents of Fe and LDH in the HQD group and the ML385 group were observably decreased. In comparison to that in the model group,the mRNA expression levels of PTGS2,HO-1,Nrf2 and Keap1 in the HQD group and the ML385 group were significantly decreased,while the level of GPX4 was increased visibly. In comparison to those in the model group,the protein expressions of PTGS2,Nrf2,Keap1 and HO-1 in the HQD group and the ML385 group were decreased,while the level of GPX4 was increased.

Conclusion

The mechanism of HQD inhibiting ferroptosis in ulcerative colitis may be the regulation of Keap1/Nrf2 pathway.

目的

基于Kelch样环氧氯丙烷相关蛋白1(kelch-like ECH-associated protein 1,Keap1)/核因子-红细胞2相关因子2(nuclear factor-erythroid 2 related factor 2,Nrf2)通路探讨黄芩汤(huangqin decoction,HQD)对溃疡性结肠炎(ulcerative colitis,UC)铁死亡的影响。

方法

体内实验分正常组、模型组、黄芩汤组(HQD)及美沙拉嗪组,葡聚糖酸钠(dextran sulfate sodium,DSS)诱导小鼠实验性溃疡性结肠炎。HE染色观察结肠组织病理情况,检测结肠组织铁含量,实时荧光定量PCR(quantitative polymerase chain reaction,q-PCR)检测谷胱甘肽过氧化物酶4(glutathione peroxidase 4,GPX4)、环氧合酶2(prostaglandin-endoperoxide synthase 2,PTGS2)、Nrf2、Keap1及血红素氧化酶1(heme oxygenase,HO-1)的信使核糖核酸(messenger RNA,mRNA)表达水平。体外实验分正常组、模型组、黄芩汤组及抑制剂组(ML385),以Erastin构建细胞铁死亡模型。CCK-8法检测细胞生长情况,检测细胞铁和乳酸脱氢酶(lactate dehydrogenase,LDH)含量,q-PCR检测GPX4、PTGS2、Nrf2、Keap1及HO-1 mRNA表达水平,蛋白免疫印迹(Western Blot,WB)检测GPX4、PTGS2、Nrf2、Keap1及HO-1的蛋白表达水平。

结果

体内实验中,与模型组相比,黄芩汤组与美沙拉嗪组在改善结肠损伤方面效果较好。与模型组相比,黄芩汤组及美沙拉嗪组铁含量明显降低。与模型组相比,黄芩汤组和美沙拉嗪组中的PTGS2、Nrf2、Keap1及HO-1的mRNA表达水平均有下降,GPX4的mRNA表达水平上升。体外实验中,与模型组相比,黄芩汤组及抑制剂组的细胞活力明显上升,铁和LDH含量明显下降,PTGS2、HO-1、Nrf2、Keap1的mRNA表达水平明显下降,GPX4的mRNA的表达水平明显上升,PTGS2、Nrf2、Keap1、HO-1的蛋白表达明显下降,GPX4的蛋白表达水平明显上升。

结论

黄芩汤抑制溃疡性结肠炎铁死亡的机制可能是调控Keap1/Nrf2通路从而减轻细胞铁死亡。

目的

基于Kelch样环氧氯丙烷相关蛋白1(kelch-like ECH-associated protein 1,Keap1)/核因子-红细胞2相关因子2(nuclear factor-erythroid 2 related factor 2,Nrf2)通路探讨黄芩汤(huangqin decoction,HQD)对溃疡性结肠炎(ulcerative colitis,UC)铁死亡的影响。

方法

体内实验分正常组、模型组、黄芩汤组(HQD)及美沙拉嗪组,葡聚糖酸钠(dextran sulfate sodium,DSS)诱导小鼠实验性溃疡性结肠炎。HE染色观察结肠组织病理情况,检测结肠组织铁含量,实时荧光定量PCR(quantitative polymerase chain reaction,q-PCR)检测谷胱甘肽过氧化物酶4(glutathione peroxidase 4,GPX4)、环氧合酶2(prostaglandin-endoperoxide synthase 2,PTGS2)、Nrf2、Keap1及血红素氧化酶1(heme oxygenase,HO-1)的信使核糖核酸(messenger RNA,mRNA)表达水平。体外实验分正常组、模型组、黄芩汤组及抑制剂组(ML385),以Erastin构建细胞铁死亡模型。CCK-8法检测细胞生长情况,检测细胞铁和乳酸脱氢酶(lactate dehydrogenase,LDH)含量,q-PCR检测GPX4、PTGS2、Nrf2、Keap1及HO-1 mRNA表达水平,蛋白免疫印迹(Western Blot,WB)检测GPX4、PTGS2、Nrf2、Keap1及HO-1的蛋白表达水平。

结果

体内实验中,与模型组相比,黄芩汤组与美沙拉嗪组在改善结肠损伤方面效果较好。与模型组相比,黄芩汤组及美沙拉嗪组铁含量明显降低。与模型组相比,黄芩汤组和美沙拉嗪组中的PTGS2、Nrf2、Keap1及HO-1的mRNA表达水平均有下降,GPX4的mRNA表达水平上升。体外实验中,与模型组相比,黄芩汤组及抑制剂组的细胞活力明显上升,铁和LDH含量明显下降,PTGS2、HO-1、Nrf2、Keap1的mRNA表达水平明显下降,GPX4的mRNA的表达水平明显上升,PTGS2、Nrf2、Keap1、HO-1的蛋白表达明显下降,GPX4的蛋白表达水平明显上升。

结论

黄芩汤抑制溃疡性结肠炎铁死亡的机制可能是调控Keap1/Nrf2通路从而减轻细胞铁死亡。

Objective

To investigate the effect of Huangqin Decoction(黄芩汤,HQD)on ferroptosis in ulcerative colitis based on kelch-like ECH-associated protein 1(Keap1)/nuclear factor-erythroid 2 related factor 2(Nrf2)pathway.

Methods

The mice in the in vivo experiment were divided into normal group,model group,traditional Chinese medicine group(HQD group)and mesalazine group. The ulcerative colitis mice were induced by dextran sulfate sodium. HE staining was used to observe the histo-pathology of colon. The contents of Fe in tissues were detected. The mRNA expression levels of glutathione peroxidase 4(GPX4),prostaglandin-endoperoxide synthase 2(PTGS2),Nrf2,Keap1 and heme oxygenase-1(HO-1)were detected by quantitative polymerase chain reaction(q-PCR). The cells in the vitro experiments were divided into normal group,model group,HQD group and inhibitor group(ML385),and the cell ferroptosis model was constructed with Erastin. The cell growth was detected by CCK-8. The contents of Fe and lactate dehydrogenase(LDH)were detected. The mRNA expression levels of GPX4,PTGS2,Nrf2,Keap1 and HO-1 were detected by q-PCR. The protein expression levels of GPX4,PTGS2,Nrf2,Keap1 and HO-1 were detected by Western Blot.

Results

In the in vivo experiments,compared with the model group,the HQD group and the mesalazine group obtained better results in ameliorating colon injury. In comparison to the model group,the Fe content was significantly decreased in the HQD group and the mesalazine group. In comparison to model group,the mRNA expression levels of PTGS2,HO-1,Nrf2 and Keap1 were decreased,the mRNA expression level of GPX4 was increased in both the HQD group and the mesalazine group. Compared with that of the model group,the cell vitality of the HQD group and the ML385 group were significantly increased. In comparison to the model group,the contents of Fe and LDH in the HQD group and the ML385 group were observably decreased. In comparison to that in the model group,the mRNA expression levels of PTGS2,HO-1,Nrf2 and Keap1 in the HQD group and the ML385 group were significantly decreased,while the level of GPX4 was increased visibly. In comparison to those in the model group,the protein expressions of PTGS2,Nrf2,Keap1 and HO-1 in the HQD group and the ML385 group were decreased,while the level of GPX4 was increased.

Conclusion

The mechanism of HQD inhibiting ferroptosis in ulcerative colitis may be the regulation of Keap1/Nrf2 pathway.
