摘要: 目的 检测双氢青蒿素(dihydroartemisinin,DHA)对人口腔鳞癌细胞KBV200多药耐药的作用,并探讨其与ROS-MAPK通路的关系。方法 利用MTT法检测不同浓度DHA对KB、KBV200细胞增殖的影响,顺铂(cisplatin,DDP)、长春新碱(vincristine,VCR)、阿霉素(adriamycin,ADM)、依托泊苷(etoposide,VP-16)对KB、KBV200细胞的增殖抑制率及加入DHA后的变化;分别联合ROS诱导剂3-AT、ERK抑制剂UO126、JNK抑制剂SP600125、p38MAPK抑制剂SB203580,观察干预前、后的逆转差异。利用流式细胞术检测各组细胞内ROS的荧光强度,采用SPSS 17.0软件包对数据进行统计学分析。结果 与KB细胞相比,KBV200细胞对VCR、VP-16、ADM药物的耐药性显著提高(P<0.05),10、20、30 μg/mL DHA作用后,KBV200细胞对VCR、VP-16、ADM的IC50显著降低,呈浓度依赖性(P<0.05)。与KB组细胞相比,KBV200组细胞ROS荧光强度显著降低(P<0.05);DHA处理后,ROS荧光强度显著增高,VCR、VP-16、ADM IC50 显著降低(P<0.05),与ROS促进剂效果一致。与KB细胞相比,KBV200细胞p-ERK/ERK、p-JNK/JNK、p-p38MAPK/p38MAPK水平显著升高(P<0.05);DHA处理后,p-ERK/ERK、p-JNK/JNK、p-p38MAPK/p38MAPK水平显著降低,VCR、VP-16、ADM IC50 显著增高(P<0.05);加入ERK抑制剂UO126、JNK抑制剂SP600125、p38MAPK抑制剂SB203580后,KBV200细胞VCR、VP-16、ADM IC50 进一步降低。结论 双氢青蒿素可能通过促进ROS生成、抑制MAPK通路而逆转KBV2001细胞的多药耐药性。

Abstract: PURPOSE: To investigate the effect of dihydroartemisinin (DHA) on multidrug resistance of human oral squamous cell carcinoma cell line KBV200 and to explore its relationship with ROS-MAPK pathway. METHODS: MTT assay was used to detect the effects of different concentrations of DHA on proliferation of KB and KBV200 cells. MTT assay was used to detect the inhibition rates of cisplatin (DDP), vincristine (VCR), adriamycin (ADM), etoposide (VP-16) on proliferations of KB and KBV200 cells and the changes after DHA addition, combined with ROS inducer 3-AT, ERK inhibitor UO126, JNK inhibitor SP600125, and p38MAPK inhibitor SB203580, respectively, the difference of reversal before and after intervention was observed; the fluorescence intensity of ROS was measured by flow cytometry. SPSS 17.0 software package was used to analyze the data. RESULTS: Compared with KB cells, drug resistances of KBV200 cells to VCR, VP-16 and ADM were significantly increased(P<0.05), after 10, 20, and 30 μg/mL DHA treatment; the IC50 of KBV200 cells to VCR, VP-16 and ADM was decreased significantly in a concentration-dependent manner(P<0.05). Compared with KB cells, ROS fluorescence intensity of KBV200 cells decreased(P<0.05); after DHA treatment, ROS fluorescence intensity increased significantly, IC50 of VCR, VP-16, ADM decreased significantly(P<0.05), which was consistent with ROS promoter effect. Compared with KB cells, the levels of p-ERK/ERK, p-JNK/JNK, p-p38MAPK/p38MAPK in KBV200 cells increased significantly (P<0.05); after DHA treatment, the levels of p-ERK/ERK, p-JNK/JNK, p-p38MAPK/p38MAPK decreased significantly, IC50 of VCR, VP-16, and ADM increased significantly(P<0.05); after adding ERK inhibitor UO126, JNK inhibitor SP600125, and p38MAPK inhibitor SB203580, IC50 of VCR, VP-16, and ADM to KBV200 cells were further reduced. CONCLUSIONS: Dihydroartemisinin may reverse multidrug resistance of KBV2001 cells by promoting ROS production and inhibiting MAPK pathway.
