目的
2
探讨龙葵的活性成分澳洲茄胺(solasodine)能否靶向ATP结合盒转运体B1(ABCB1)克服前列腺癌细胞多西他赛耐药及其作用机制。
方法
2
通过网络药理学分析龙葵的活性成分及靶基因。通过分子对接评估solasodine与ABCB1的结合情况。通过噻唑蓝(MTT)实验检测solasodine对前列腺癌细胞多西他赛耐药性的影响。通过Western blot法与免疫荧光染色法检测solasodine对ABCB1蛋白表达、亚细胞定位以及蛋白激酶B(Akt)、细胞外调节蛋白激酶(ERK)通路的影响,并通过流式细胞术检测solasodine对药物累积与外排的影响。
结果
2
网络药理学分析结果显示,solasodine对前列腺癌的治疗作用可能与ABCB1有关。分子对接结果显示,solasodine与ABCB1蛋白可以稳定结合。MTT实验结果显示,solasodine能靶向ABCB1克服前列腺癌多西他赛耐药。Western blot法与免疫荧光染色法结果表明,solasodine不影响ABCB1在细胞内的表达与定位,也不影响Akt与ERK信号通路;流式细胞术结果显示,solasodine通过抑制ABCB1蛋白的外排功能,增加前列腺癌细胞内多西他赛的蓄积,从而克服多西他赛耐药。
结论
2
龙葵活性成分solasodine可以靶向ABCB1有效克服前列腺癌细胞多西他赛耐药。
Objective
2
To explore whether solasodine, an active component
of
Solanum nigrum
L., can target ATP binding cassette subfamily B member 1 (ABCB1) to overcome docetaxel resistance in prostate cancer and to elucidate its mechanism of action.
Methods
2
The active components and target genes of
Solanum nigrum
L. were analyzed by network pharmacology. The interaction between solasodine and ABCB1 was assessed using molecular docking. The effect of solasodine on docetaxel resistance in prostate cancer cells was detected by thiazole blue (MTT) assay. The effects of solasodine on ABCB1 expression, localization, protein kinase B (Akt) and extracellular regulatory protein kinase (ERK) pathways were detected by Western blot and immunofluorescence. Additionally, the effects of solasodine on drug accumulation and efflux were detected by flow cytometry.
Results
2
Network pharmacological analysis result showed that the therapeutic effect of solasodine on prostate cancer were potentially associated with ABCB1. Molecular docking result revealed that solasodine could bind stably to ABCB1. MTT assay result demonstrated that solasodine could overcome docetaxel resistance by targeting ABCB1. Western blot and immunofluorescence results showed that solasodine did not affect ABCB1 expression and localization, nor did it affect Akt and ERK signaling pathways. Flow cytometry result showed that solasodine overcame docetaxel resistance by inhibiting ABCB1 efflux and increasing intracellular drug accumulation.
Conclusion
2
Solanum nigrum
L.'s
active component solasodine can target ABCB1 to effectively overcome docetaxel resistance in prostate cancer.
