    • 摘要: 目的:观察地西他滨(DAC)对人慢性粒细胞白血病耐药细胞株K562/A02阿霉素(ADR)耐药性的影响,探讨其作用的可能机制.方法:分别或联合应用不同浓度ADR和DAC作用于K562/A02细胞和其亲本细胞株K562,采用CCK-8法检测药物细胞毒性,Sequenom MassARRAY系统结合比色法评价DNA甲基化程度,流式细胞术检测K562/A02细胞细胞周期分布和细胞凋亡率.结果:K562/A02细胞较K562细胞具有显著ADR耐药性,前者ADR作用24 h的IC50约为后者的50倍.而对DAC,在0.5~8μmol/L作用浓度范围内,K562/A02细胞则较K562细胞更敏感.在相同ADR作用浓度(4.31和17.24 μmol/L)下,联合1μmol/L DAC处理24 h能显著提高K562/A02细胞对ADR的敏感性,细胞存活率下降(P<0.05).DAC和ADR均能影响K562/A02细胞的细胞周期进程和细胞凋亡率.1 μmol/L DAC的影响与作用时间相关,在作用24 h时以S期阻滞与细胞早期凋亡率升高为主,48 h时以G2/M期阻滞与细胞晚期凋亡和坏死率升高为主.ADR则主要表现为浓度依赖性G2/M期阻滞并诱导细胞晚期凋亡和坏死.两者联用使ADR对细胞周期分布的作用进一步加强,即表现为G2/M期阻滞更加明显,但对细胞凋亡率的影响并无显著差异.而在基因组甲基化程度上,2种细胞没有显著差异,DAC作用前后也没有显著改变.结论:DAC能增强K562/A02细胞对ADR的敏感性,具有逆转耐药作用,其机制可能与调节K562/A02细胞细胞周期进程、促进细胞凋亡和坏死有关.

    • 摘要: 目的:探索木香烃内酯对白血病耐药细胞系 K562/A02阿霉素耐药的逆转作用。方法将木香烃内酯与 K562/A02细胞共培养72 h后,采用MTT法检测木香烃内酯对细胞生长的抑制作用。不同浓度木香烃内酯处理K562/A02细胞24 h后,采用Annexin V和PI双染法检测木香烃内酯对细胞的凋亡。不同浓度木香烃内酯与阿霉素共培养72 h后采用MTT法检测木香烃内酯对K562/A02细胞的耐药逆转情况。采用流式细胞仪检测木香烃内酯处理24 h之后K562/A02细胞阿霉素蓄积以及细胞膜表面P-糖蛋白(P-gp)的表达。结果木香烃内酯对K562/A02细胞的生长具有明显抑制作用,呈显著的剂量相关性。与对照组比较,2.5~50µmol/L木香烃内酯组K562/A02细胞存活率显著降低(P<0.05、0.01、0.001)。随着木香烃内酯浓度的增加,凋亡细胞的比例明显增加。与对照组比较,不同浓度木香烃内酯组细胞凋亡比例显著升高(P<0.05、0.01、0.001)。加入5µmol/L木香烃内酯后,使K562/A02细胞对阿霉素的敏感性提高12倍。木香烃内酯处理后K562/A02细胞内部阿霉素的蓄积明显增加,呈浓度相关性。与对照组比较,5、10µmol/L木香烃内酯组K562/A02细胞内部阿霉素的蓄积增加显著升高(P<0.05)。细胞表面的 P-gp 的表达并无显著影响。结论木香烃内酯能够抑制 K562/A02细胞增殖,诱导K562/A02细胞凋亡,增强阿霉素的化疗敏感性,逆转阿霉素耐药。%Objective To investigate the reverse effect against adriamycin resistance of costunolide on leukemia drug resistant cell line K562/A02. Methods Costunolide and K562/A02 cells were co-cultured for 72 h, and inhibition of costunolide on K562/A02 cell were determined by MTT assay. K562/A02 cells were treated for 24 h by various concentrations of costunolide, and the apoptosis of K562/A02 cells were detected by Annexin V/PI apoptosis kit on flow cytometry. Various concentrations of costunolide and adriamycin were co-cultured with K562/A02 cells for 72 h, and the reversals were determined by MTT assay. Accumulation of adriamycin and the expression of P-glycoprotein (P-gp) were analyzed by flow cytometry after the treatment for 24 h of costunolide with various concentrations. Results Costunolide could significantly exhibit growth of K562/A02 cell in a dose dependent manner. Compared with the control group, survival rates of K562/A02 cell in the costunolide 2.5 — 50 µmol/L groups were significantly decreased (P<0.05, 0.01, 0.001). Apoptosis ratios of K562/A02 cells in the costunolide groups were significantly decreased with increase of concentrations of costunolide. Compared with the control group, apoptosis rates of K562/A02 cell in the costunolide groups were significantly increased (P<0.05, 0.01, 0.001). Intake of adriamycin in K562/A02 cell increased to 12 times after treated by 5 µmol/L costunolide. Accumulation of adriamycin in K562/A02 cell treated by costunolide were significantly increased in a concentration dependent manner. Compared with the control group, accumulation of adriamycin in K562/A02 cell in the 5 and 10 µmol/L costunolide groups were significantly increased (P<0.05). However, there was no significant difference of expressions of P-gp between two groups. Conclusion Costunolide can inhibit the proliferation of K562/A02 cells, induce apoptosis in K562/A02 cells, enhance chemotherapy sensitivity of doxorubicin, and reverse adriamycin resistance.

    • 摘要: 目的:研究柚皮素对MDR1 mRNA与P-糖蛋白(P-gp)表达的影响及其分子生物学机制。方法:将不同浓度的柚皮素(50、100、250、500μmol/L)单独或联合阿霉素(5μmol/L)作用于K562/A02细胞48 h,RT-PCR法检测MDR1 mRNA的表达水平,Western-blot法检测P-gp的表达水平,并以NF-κB抑制剂吡咯烷二硫代氨基甲酸盐(PDTC)为对照,比较柚皮素与PDTC间的差异。结果:系列浓度柚皮素作用于K562/A02细胞48 h后能显著抑制MDR1 mRNA(IC_(50)=460.3μmol/L)及P-gp的表达(IC_(50)=286.3μmol/L),抑制作用随浓度的增加而增强;无毒剂量的柚皮素抑制强度与PDTC相近(P>0.05);经阿霉素诱导后二者抑制效应仍然相仿(P>0.05)。结论:柚皮素明显抑制K562/A02细胞MDR1 mRNA及P-gp的表达,可能与PDTC的作用机制相同,即限制IκB-α磷酸化,阻抑NF-κB的活化,从而抑制MDR1的转录,导致MDR1 mRNA及P-gp的表达量下调,最终使得药物外排转运效应下降。

    • 摘要: 目的:研究恶性血液病细胞株孕烷X受体(Pregnane X receptor)的表达水平;探讨藤黄酸(Gambogic acid,GA)对K562/A02耐药细胞株的耐药逆转作用及其机制.方法:应用Real-time PCR法检测多个恶性血液病细胞株中PXR的表达;采用MTT法检测K562/A02细胞株分别与GA,DNR,GA+ DNR孵育24、36、48 h后的细胞增殖抑制率;Real-time PCR法检测各实验组PXR表达;Western blot法检测各实验组细胞PXR蛋白的表达水平.结果:K562/A02细胞株的PXR基因表达水平高于本研究实验其他所检测的恶性血液病细胞;;藤黄酸作用后,K562/A02细胞对柔红霉素的耐药性明显降低,却细胞抑制率增加;藤黄酸作用后的K562/A02细胞的PXR基因和蛋白表达水平均较对照纽下调,而在柔红霉素组则无明显变化,提示柔红霉素并没有下调PXR的作用.PXR的下调亦不是细胞被药物杀伤后的假象,而藤黄酸可以下调PXR的基因和蛋白表达.结论:PXR可在多种血液系统恶性肿瘤细胞株中表达,并在K562/A02细胞明显较其他实验细胞株中表达高.低剂量GA可以提高细胞的生长抑制率,增强化疗的效果,其机制可能与下调PXR表达有关.

    • 摘要: Objective To detect the expression of miR⁃155 and Ets⁃1 in leukemia cell line K562 and adriamycin resistance K562/A02 cell line, and explore the relationship between miR⁃155, Ets⁃1 and drug resistance in leukemia treatment. Methods miR⁃155 simulation oligonucleotide probes and miR⁃155 inhibitor oligonucleotide probes, Ets⁃1 expression plasmid and Ets⁃1 interference expression plasmid were transfected in K562 and K562/A02 cells by Lipofectamine 2000. Real⁃time quantitative PCR was used to de⁃termine the expression of miR⁃155, Ets⁃1 and multidrug resistance( MDR1) . The protein levels of Ets⁃1 and MDR1 were analyzed by Western blotting. The viability of K562 and K562/A02 cells was evaluated by MTT assay. Results The expression levels of miR⁃155, Ets⁃1 and MDR1 were significantly increased in K562/A02 cells than those in K562 cells. Down⁃regulation of miR⁃155 could obviously increase the inhibition rate of adriamycin on K562/A02 cells and inhibit the expression of Ets⁃1 and MDR1, which could be reversed by overexpression of Ets⁃1. While, up⁃regulation of miR⁃155 could significantly increase the inhibition rate of adriamycin on K562 cells and stimulate the expression of Ets⁃1 and MDR1, which could be reversed by Ets⁃1 siRNA. Conclusion miR⁃155 is involved in the mechanism of drug resistance in leukemia by regulating Ets⁃1 expression, which may provide a potential novel target for overcoming drug⁃resistance.%目的通过检测人白血病细胞株K562及阿霉素耐药细胞株K562/A02中miR⁃155和Ets⁃1表达,探讨miR⁃155、Ets⁃1表达与白血病化疗耐药的关系。方法利用Lipofectamine 2000将含有miR⁃155模拟物和miR⁃155抑制物的寡核苷酸探针、Ets⁃1过表达质粒以及Ets⁃1干扰质粒转染K562及K562/A02细胞,实时荧光定量PCR法检测miR⁃155、Ets⁃1及多药耐药基因( MDR1)的表达,Western blotting检测Ets⁃1和MDR1蛋白表达水平;转染后的K562及K562/A02细胞经阿霉素处理24 h,MTT法检测细胞存活率。结果与K562细胞相比,K562/A02细胞中miR⁃155、Ets⁃1和MDR1表达水平显著升高( P<005)。抑制miR⁃155表达能显著增强阿霉素对K562/A02细胞的抑制作用,并抑制Ets⁃1和MDR1表达,而MDR1表达抑制效应可被Ets⁃1过表达所逆转。结论 miR⁃155通过调节Ets⁃1表达参与白血病耐药形成,miR⁃155有可能成为逆转白血病耐药的作用靶点。

    • 摘要: 本研究旨在探讨晚期糖基化终末产物(AGE)对K562及K562/A02细胞增殖的影响及汉防己甲素(Tet)对AGE诱导细胞增殖的干预作用,并初步探讨其可能机制.用CCK8法观察AGE对K562及K562/A02细胞增殖及Tet对AGE诱导细胞增殖的影响,流式细胞术检测细胞凋亡率及晚期糖基化终末产物受体(RAGE)的表达,并用半定量RT-PCR检测RAGE mRNA相对表达水平.结果显示:AGE可促进K562及K562/A02细胞增殖,呈浓度依赖性,0-48 h内细胞增殖随时间延长而增强,72 h增殖仍明显高于对照组;AGE上调两种细胞RAGE mRNA及其蛋白的表达,具有浓度依赖性;Tet与AGE共作用于K562及K562/A02细胞48h,可通过诱导细胞凋亡抑制AGE促细胞增殖的作用,且呈浓度依赖性,但Tet对AGE诱导RAGE mRNA及其蛋白表达的增加未见明显影响.结论:AGE可促进K562及K562/A02细胞增殖,其机制可能与上调细胞RGAEmRNA及其蛋白的表达有关;Tet可抑制AGE诱导的K562及K562/A02细胞增殖,其机制可能与改变AGE诱导的RGAEmRNA及其蛋白表达增加无关.%This study was aimed to investigate the effect of advanced glycosylation end products(AGE) on the proliferation of K562 and K562/A02 cells, the effect of tetrandrine(Tet) on proliferation of K562 and K562/A02 cells induced by AGE, and their mechanisms. The effects of AGE on proliferation of K562 and K562/A02 cells and Tet on the proliferation of AGE-mduced K562 and K562/A02 cells were assayed by CCKS kit, the apoptosis rale and the expression of receptor of advanced glycosylation end products(RAGE) in K562 and KS62/A02 cells were determined by flow cy-tometry, the expression of RAGE mRNA was detected by semi-quantitative RT-PCR. The results showed that AGE could promote the proliferation of K562 and K562/A02 cells in a concentration-dependent manner, the cell proliferation was enhanced with time increasing in 0 -48 h, and was higher than control group after 72 h. AGE up-regulated the RAGE mRNA and protein expressions of K562 and K562/A02 cells in a concentration-dependent manner. Treatment of Tet combined with AGE for 48 h could inhibit the proliferation of K562 and K562/A02 cells promoted by AGE in a concentration-dependent manner, which probably by inducing cell apoptosis, however, there was no obvious effect in the up-regulating expression of RAGE mRNA and protein induced by AGE. It is concluded that AGE can promote the proliferation of K562 and K562/A02 cells, which is probably induced by up-regulating the expression of RAGE mRNA and protein. Tet can inhibit the proliferation of K562 and K562/A02 cells induced by AGE, and the mechanism may be not closely associated with changes of the up-regulating expression of RAGE mRNA and protein induced by AGE.
