Tectochrysin (Techtochrysin) 抑制 NF-κB 的活性。Tectochrysin (Techtochrysin) 直接与 p50 单元结合。Tectochrysin (Techtochrysin) 通过抑制 IκB 的磷酸化,浓度依赖性地抑制 p50 和 p65 转运到细胞核中。为了评估 Tectochrysin 对结肠癌细胞 (SW480、HCT116) 细胞生长的抑制作用,通过 MTT 测定法分析细胞活力。用不同浓度的 Tectochrysin (Techtochrysin)? (1,5,10 μg/mL) 处理细胞 24 小时。Tectochrysin (Techtochrysin) 以浓度依赖性方式抑制结肠癌细胞的细胞生长。Tectochrysin (Techtochrysin) 抑制 SW480 细胞生长,IC50 值为 6.3 μg/mL 和 HCT116 细胞生长,IC50 值为 8.4 μg/mL。形态学观察表明,NSC 80687 (10 μg/mL) 处理 SW480 细胞和 HCT116 细胞后,细胞体积减小。然而,在通过 MTT 测定法检测的浓度下,鸢尾黄素 (Techtochrysin) 在正常 CCD-18co 细胞中没有细胞毒性。为了描述凋亡细胞死亡的诱导是否对 NSC 80687 的细胞生长抑制至关重要,使用 DAPI 染色评估细胞染色质形态的变化。为了进一步表征 Tectochrysin (Techtochrysin) 引起的凋亡细胞死亡,进行了 TUNEL 染色测定,然后通过荧光显微镜分析标记的细胞。SW480 细胞中的凋亡细胞数 (DAPI 阳性 TUNEL 染色细胞) 在 0 和 10 μg/mL NSC 80687 的作用下分别增加到 1 和 58 %,在 HCT116 中通过 0 和 10 μg/mL Tectochrysin 分别增加到 1 和 54 %[1]

体内研究
(In Vivo)

为了阐明 Tectochrysin 在体内的抗肿瘤作用,研究了 Tectochrysin (NSC 80687) 处理后结肠癌异种移植裸鼠的肿瘤生长情况。在 HCT116 异种移植物研究中,Tectochrysin (NSC 80687) 每周两次腹膜内给药,持续 3 周,小鼠的肿瘤体积为 200 至 300 mm3。小鼠每周称重两次。在实验期间,对照组和 Tectochrysin (NSC 80687) 处理的小鼠 (n=10) 之间的体重变化没有显著差异。然而,在第 21 天,记录了最终的肿瘤重量。用 5 mg/kg 剂量的 Tectochrysin (NSC 80687) 处理的小鼠的肿瘤重量和体积分别是载体组的 57.9% 和 46.4%[1]

动物实验:

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

    请依序添加每种溶剂: 10% DMSO    90% Corn Oil

    Solubility: ≥ 1 mg/mL (3.73 mM); 澄清溶液

    此方案可获得 ≥ 1 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。

    1 mL 工作液为例,取 100 μL 10.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

Cell Assay
[1]

Each SW480, HCT116, HT-29, A549 and MCF-7 cell line (1×104 cells) is incubated in 200 μL of RPMI 1640, DMEM medium with NSC 80687 (concentrations ranging from 1, 5, 10 μg/mL) in a 96-well flat-bottomed plate in triplicate. After incubation for 72 h at 37°C, MTT diluted in RPMI 1640, DMEM medium are added to each well and incubation is carried out for 90 min. The supernatant is then discarded and the crystal products are eluted with DMSO (200 μL/well). Colorimetric evaluation is performed with a spectrophotometer at 540 nm. The apoptosis assay is first performed by using DAPI staining. SW480 and HCT116 human colon cancer cells are cultured with concentrations of NSC 80687 (5 μg/mL), and induction of apoptotic cell death is evaluated after 24 h. Tunel assay is done[1].

Animal Administration
[1]

Mice[1]
Five-week-old male BALB/c athymic nude mice (n=10/group) are used. HCT116 cancer cells are injected subcutaneously (1×107 cells/0.1 mL PBS/animal) into the lower right flanks of mice. After 14 days, when the tumors have reached an average volume of 200-300 mm3, the tumor-bearing nude mice are intraperitoneally injected with Tectochrysin (NSC 80687) (5 mg/kg dissolved in 0.1 % DMSO) twice per week for 3 weeks. The tumor volumes are measured with vernier calipers and calculated[1].

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.
