    生物活性

    iCRT3 is an inhibitor of both Wnt and β-catenin-responsive transcription.

    IC50 & Target

    Wnt[1], β-catenin-responsive transcription[2]

    体外研究
    (In Vitro)

    iCRT3 is an inhibitor of both Wnt and β-catenin-responsive transcription. iCRT3 significantly decreases TOP Flash activity and reduces the level of NTSR1. The anti-apoptotic effects of Neurotensin (NTS) and Wnt3a can be largely abrogated by iCRT3[1]. Cells maintained long term with iCRT3 show enhanced expression of classic pluripotency genes compare with the DMSO control, whereas expression of differentiation markers and T-cell factor (TCF) target genes is concomitantly reduced[2]. Treatment with iCRT3 at doses of 12.5, 25, 50, and 75 μM decreases TNF-α levels by 14.7%, 18.5%, 44.9% and 61.3%, respectively. With iCRT3 treatment, IκB levels are increased in a dose-dependent manner compare to the vehicle[3].

    体内研究
    (In Vivo)

    The tumor growth rates are markedly retarded by iCRT3 treatment. Consistently, the tumor-suppressive role of iCRT3 is accompanied with a reduction in Ki67 index, a proliferation marker[1]. The IL-6 levels in the 10 mg/kg iCRT3 treatment group are 82.9% lower than those in the vehicle group. IL-1β levels are undetectable in the sham but reach 371 pg/mL in septic mice and are down by 30.2% and 53.2%, respectively, with 5 and 10 mg/kg iCRT3. With iCRT3 treatment at doses of 5 and 10 mg/kg, AST levels in these septic mice are 15.4% and 44.2% lower, respectively, than those in the vehicle-treated mice. After treatment with 10 mg/kg iCRT3, lung morphology is improved with much reduced microscopic deterioration, compare to the vehicle group. The number of apoptotic cells in the lung tissues of the iCRT3-treated mice is significantly reduced by 92.7% in comparison with the vehicle group[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

      请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.5 mg/mL (6.34 mM); 澄清溶液

      此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

      1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

      生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。

    Cell Assay
    [1]

    Cells are seeded into 96-well plates to a density of 5×103 cells per well and incubated in the culture medium with iCRT3 for an additional 48 h. Cell viability and cell apoptosis assays are carried out using a Cell Counting kit-8 and a Caspase-Glo 3/7 assay kit according to the manufacturer’s instructions, respectively[1].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [1]

    NOD-SCID BALB/c mice are inoculated subcutaneously in the right back with 2×106 A172 cells. The growth of the primary tumors is recorded every 4 days. iCRT3 (5 mg/kg) is diluted in PBS i.p. triweekly when tumors grow to ~200 mm3. The control mice are treated with blank PBS containing 5% (v/v) DMSO. Tumor volume is evaluated with the following formula: volume=tumor length×width2/2. The mice are sacrificed 24 days after pharmaceutical treatment. The tumors are resected and embedded in paraffin, and the Ki67 staining is analyzed by immunohistochemistry[1].

    • 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.
