    体外研究
    (In Vitro)

    Nigericin (0.1 μM) 以剂量依赖的方式降低抑制 H460 肺癌细胞的增殖和克隆形成。尼日利亚菌素抑制 H460 肺癌细胞迁移和侵袭[1]。Nigericin (0.1-10 nM) 显然对细胞体积有双重作用,即在较低的 Nigericin 浓度下有收缩作用,在较高浓度下有膨胀作用。Nigericin (0.1-1 nM) 显著降低细胞溶质 pH (pHi),并在 5 和 10 nM 时略微增加 PHi[2]。Nigericin 对 S18 细胞的毒性高于 S26 细胞,IC50 分别为 2.03±0.55 μM 和 4.77±2.35 μM。Nigericin 可以在体外选择性地杀死 NPC 中的癌症干细胞。Nigericin 显著降低 S18 和 HONE-1 细胞的迁移能力[3]。Nigericin 对 HT29 和 SW116 细胞系表现出胎儿毒性,IC50 分别为 12.92±0.25 μMol 和 15.86±0.18 μMol。在标准软琼脂测定中,尼日利亚菌素还表现出在不依赖贴壁的条件下形成菌落的能力下降[4]

    体内研究
    (In Vivo)

    Ngericin (4 mg/kg,ip) 显著减少肿瘤生长并与化疗剂 DDP 协同作用,如肿瘤体积所示。Nigericin 在体内显著降低 Bmi-1。Bmi-1 的过表达部分恢复了尼日利亚菌素处理下 NPC 细胞的 CSC 含量和转移能力。Bmi-1的下调可能与尼日利亚菌素对鼻咽癌干细胞的抑制作用有关[3]

    请根据您的 实验动物和给药方式 选择适当的溶解方案。

    以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
    ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
    以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

    • 方案 一

    Cell Assay
    [1]

    For RCCs, cells (appr 2000 cells/well) are plated in 96-well cell-culture microplates and incubated over nigericinht in complete media (CM)-RPMI 1640 supplemented with 5% FBS and 2 mM l-glutamine. Cells are then exposed to the appropriate concentration of drug or vehicle for 72 h. For PPSS, cells (appr 500 cells/well) are plated in 96-well cell-culture microplates incubated over Nigericinht in CM to allow them to adhere and then maintained in serum-free media for 7-8 days and then treated with the appropriate concentration of drug or vehicle for 72 h in SFM. Cell viability for cells growing under RCCs and PPSS are evaluated by the MTT assay. The absorbance of solubilized formazan is read at 570 nm using ELISA (enzyme-linked immunosorbent assay) reader. In all cases, the highest concentration of DMSO is used in the control and this concentration is maintained below 0.001% (v/v). This DMSO concentration does not show any significant antiproliferative effect on the cell line in a short-term assay.

    Animal Administration
    [3]

    Mice[3]
    The S18 cells are injected near the scapula of the nude mice. Nine days after injection, the mice are randomly divided into four groups with six animals each (control, DDP, Nigericin and DDP combined with Nigericin). DDP (2.5 mg/kg) is injected intraperitoneally for five continuous days and nigericin (4 mg/kg) is administrated intraperitoneally every two days. Tumor length and width are measured with a vernier caliper every other day. Tumor volume is calculated using the formula V=0.5×(length×width2). The body weights of the mice are recorded every two days. Mice are humanely euthanized when the tumor volume reach 2000 mm3.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
