Description

LF3 is an antagonist of the β-Catenin/TCF4 interaction with antitumor activity; has an IC50 of 1.65 μM.

IC50 & Target

IC50: 1.65 μM (β-Catenin/TCF4, AlphaScreen), 1.82 μM (β-Catenin/TCF4, ELISA)[1]
In Vitro

LF3 inhibits Wnt/β-catenin signals in cells with exogenous reporters and in colon cancer cells with endogenously high Wnt activity. LF3 also suppresses features of cancer cells related to Wnt signaling, including high cell motility, cell-cycle progression, and the overexpression of Wnt target genes. However, LF3 does not cause cell death or interfere with cadherin-mediated cell-cell adhesion. Remarkably, the self-renewal capacity of cancer stem cells is blocked by LF3 in concentration-dependent manners[1].

In Vivo

LF3 reduces tumor growth and induces differentiation in a mouse xenograft model of colon cancer. Tumor growth is significantly reduced when mice with GFPhigh cells are treated with LF3 at 50 mg/kg. LF3 treatment does not disturb the normal histology of the gut of mice[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (6.00 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (4.99 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Cell Assay
[1]

LF3 is dissolved in DMSO to a concentration of 50 mM and diluted with culture medium. Two colon cancer cell lines (HCT116 and HT29) and a breast cancer cell line (MCF7) are treated with LF3 (0, 30, 60 μM) for 24 hours and labeled with BrdUrd for 4 to 5 hours to detect proliferating cells[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration
[1]

Mice: Unsorted GFPlow and GFPhigh SW480 cells are subcutaneously injected into the back skin of NOD/SCID mice. Tumor growth is monitored over a period of 45 days. For therapy, LF3 is administered i.v. at 50 mg/kg body weight for three rounds over 5 consecutive days, with 2-day breaks[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.
