    • 摘要: 乳腺癌是女性中一种高发的肿瘤,具有高度的变异性,从无痛性乳癌到致死性乳癌。丙戊酸钠(VPA)是临床唯一使用的组蛋白脱乙酰基酶抑制剂(HDACI)。然而在临床和动物实验上丙戊酸钠在乳腺癌使用的研究结果是相互矛盾的,也是不充分的。此外,我们对乳腺癌与肿瘤转移抑制基因NM23H1的内在关系也是不清楚的。我们猜测丙戊酸钠能上调NM23H1基因的表达,并且能影响肿瘤细胞的迁移和/或侵袭。我们的试验结果发现在浓度为O.8~3.2mM/L的丙戊酸钠上调NM23H1基因的表达,与剂量有关,并且抑制乳腺癌细胞的迁移。上调NM23H1的表达可能是丙戊酸钠的抗癌机制之一。总之,我们的研究结果揭示了丙戊酸钠可以用于乳腺癌的治疗。
    • 摘要: Objective To investigate the effect of different formulae composed from the therapeutic principle of Qi-boosting toxin-resolving on the migrating potentiality and associated gene expressive activities of nasopharyngeal carcinoma (NPC) cell line CNE2Z cells. Methods Firstly, different formulae derived from the same therapeutic principle of Qi-boosting toxin-resolving were composed only with their dosages changed but not with their composing kinds of herbs, i.e. the original formula (OF) and the modified one (MF). Herbal medicines-containing plasma (HMCP) were prepared routinely from rats by feeding method with these two formulae. Then, HMCP of these two formulae were cultured with CNE2Z cells in different concentrations respectively to detect their effects on migrating potentiality of these cells by scratching test. Immunohistochemical SABC assay was used to determine the expressive levels of nm23-H1 and c-myc in different groups of cells, and RT-PCR techniques were taken to confirm the transcribing activities of nm23-H1 mRNA and c-myc mRNA. Their interaction was evaluated by careful analysis on these data at last. Results TIt was shown from the experiment of scratching that the motility ability of targeting cells was significantly inhibited by the effect of OF and promoted by the effect of MF, inhibit potentiality of motility of CNE2, modified QBTRF promote potentiality of motility of CNE2. However, their effects on the expression of nm23-H1 and c-myc genes were rather complicated. OF showed no obvious effect on the expression of c-myc but giving rise a promoting effect on that of nm23-H1 protein (P0.05). In contraction, MF produced a promoting effect on the expressive activity of c-myc mRNA at higher dosage, significantly higher than that of controlling group(P0.05). Conclusion The original Qi-Boosting Toxin-Resolving formula gives rise an inhibitory effect on migrating potentiality of CNE2Z cells, while the modified Qi-Boosting Toxin-Resolving formula induces a kind of promoting effect on this potentiality of these cells, though only with the dosages changed without the herbal kinds changed in this formula. Such a kind of effect induced by MF may be associated with its special effects on the expression of nm23-H1 and c-myc genes and their interaction among them. It should be confirmed in following studies further. Moreover, the results from this work are also of significance for future study how to plan the dosage distribution rightly when composing a herbal formula.%  目的观察益气解毒法不同组方对CNE2Z鼻咽癌细胞迁徙运动潜能的影响并探讨其效应与相关基因表达活性变化的关系。方法依据益气解毒法组成原方并在此基础上依法构建改方,分别制备不同浓度含药血浆并作用于相同靶细胞CNE2Z鼻咽癌细胞,划痕法检测药物干预前后靶细胞的迁徙运动潜能,免疫组化法和RT-PCR法分别检测干预前后靶细胞nm23和c-myc蛋白表达水平和mRNA转录活性,比较分析组间差异。结果细胞迁徙运动能力检测结果显示,原方呈现抑制效应而改方表现则促进效应(P<0.05)。免疫组化检测结果,在c-myc与nm23-H1蛋白表达活性上,原方对前者表达活性无明显影响但后者显著增强,差异均有统计学意义(P<0.05);改方则对c-myc蛋白表达显示促进效应,对nm23-H1蛋白表达显示抑制效应(P<0.05)。RT-PCR检测结果则显示,原方及改方的高中剂量处理组细胞nm23-H1 mRNA表达显著升高(P<0.05),低剂量组则无明显变化(P>0.05);改方高剂量组c-myc mRNA表达水平明显高于对照组(P<0.05),原方组则未显示明显药理效应(P>0.05)。结论益气解毒原方对CNE2Z细胞的迁徙运动潜能发挥抑制效应,而由剂量变化构建的改方虽然显示有促进效应,可能与其影响nm23-H1及c-myc表达活性及交互作用有关,还需要进一步研究证实。研究结果也对中药组方中剂量把握的重要性提供了初步的实验依据。

    • 摘要: OBJECTIVE To investigate the synergistic effect of decitabine(DCA) and valproic acid(VPA) on non-metastasis 23-H1 (nm23-Hl) gene expression in gastric MGC-803 cells. METHODS The groups were set as follows: DCA 1.5 and 3.0 umol·L-1, VPA 1.5 mmol·L-1, DCA 1.5 umol·L-1+VPA 1.5 mmol·L-1, DCA 3.0 umol·L-1+VPA 1.5 mmo·L-1. The cells were treated by drug for 72 h. The early and late apoptosis rates were detected by staining with Annexin V and PI. The nm23-Hl mRNA expressions levels were detected by real-time quantity PCR. Methylation status of 2 CpG island selected randomly was detected by pyrosequencing. RESULTS The apoptosis rates of VPA 1.5 +DCA 1.5 group [early: (33.58±3.88)%, late: (31,52±4.20)%] and VPA 1.5+DCA 3.0 [early: (42.61±4.23)%, late: (38.01±3.86)%] were significantly higher than their corresponding concentration single drug groups (P<0.01). The nm23-Hl mRNA relative expression in VPA 1.5+DCA 1.5 group (1.84±0.46) and VPA 1.5+DCA 3.0 group(3.02±0.36) were significantly higher than their corresponding concentration single drug groups(P<0.01). The methylation percentages of 2 CpG islands of nm23-Hl promoter in VPA 1.5 +DCA 1.5 group [sitel: (53.50±3.39)%, site2: (51.17±2.71)%] and VPA 1.5+DCA 3.0 group [sitel: (41.17±2.14)%, site2: (39.83±2.56)%] were significantly lower than their corresponding concentration single drug groups(P<0.01). The histone deacetylases(HDAC) activity of each of VPA 1.5mmol·L-1, VPA 1.5+DCA 1.5, VPA 1.5+DCA 3.0 groups was significantly lower than either of Normal control, DCA 1.5 umol·L-1, DCA 3.0 umol·L-1 groups(P<0.01). CONCLUSION The induction of nm23-Hl mRNA expression by combinations of DCA and VPA is dependent on decreasing the methylation status of nm23-Hl promoter and reducing HDAC activity in gastric MGC-803 cells.%目的 探讨地西他滨(DCA)和丙戊酸钠(VPA)联用对胃癌细胞株MGC-803的作用及对non-metastasis 23-H1基因(nm23-H1)的表达调控的影响.方法 DCA 1.5及3.0 μmol·L-1-1VPA 1.5 mmol·L-1,DCA 1.5 μmol·L-1+VPA 1.5 mmol·L-1,DCA 3.0 μmol·L-1+VPA 1.5 mmo·L-1作用MGC-803细胞72 h.Annexin V/PI法检测细胞凋亡,实时荧光定量PCR检测nm23-H1 mRNA表达,焦磷酸测序法检测nm23-H1启动子上随机选取的两个CpG岛位点甲基化状态.结果 VPA 1.5+DCA 1.5联合用药组[早期:(33.58±3.88)%,晚期:(3 1.52±4.20)%]和VPA 1.5 +DCA 3.0联合用药组[早期:(42.61±4.23)%,晚期:(38.01±3.86)%]凋亡率均高于其相应单药组,差异具有统计学意义(P<0.01).nm23-H1 mRNA在VPA 1.5 +DCA 1.5联合用药组(1.84±0.46)和VPA 1.5 +DCA 3.0联合用药组(2.88±0.42)的表达水平均高于其相应单药组,差异具有统计学意义(P<0.01).VPA 1.5 +DCA 1.5联合用药组[位点1:(53.50±3.39)%,位点2:(51.17±2.71)%]和VPA 1.5 +DCA 3.0联合用药组[位点1:(41.17±2.14)%,位点2:(39.83±2.56)%]nm23-H1启动子两位点甲基化阳性率均低于其相应单药组,差异具有统计学意义(P<0.01).VPA 1.5 mmol·L-1、VPA 1.5+DCA 1.5、VPA 1.5+DCA 3.0这3组的HDAC酶活性均低于正常对照、DCA 1.5 μmol.L-1、DCA 3.0 μmol·L-1任一组,差异具有统计学意义(P<0.01).结论 DCA联合VPA能显著上调nm23-H1基因的表达,其机制与启动子上的甲基化水平降低和去乙酰化酶活性降低有关.
