Description

ReACp53 could inhibit p53 amyloid formation and rescue p53 function in cancer cell lines.

IC50 & Target

p53 amyloid formation[1].

In Vitro

ReACp53 penetrates into HGSOC primary cancer cells and converts mutant p53 from a punctate state into soluble WT-like p53. ReACp53 also induces cancer cell death, cell cycle arrest and results in p53 degradation. ReACp53 specifically affects cell viability and proliferation of cancer cells bearing mutant p53 but not wild type when grown as organoids[1].

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

In Vivo

Only mutant p53-bearing tumors in the ReACp53-treated mice cohorts are 80-90% smaller in weight than the control cohort, confirming the ability of ReACp53 to limit tumor proliferation and shrink tumors. A significant reduction of Ki67 positive cells is evident in ReACp53-treated OVCAR3 xenografts, indicative of a reduced proliferative index. Similar results are observed in the minimal residual disease model. In the paradigm, administration of ReACp53 results in a significant increase in p21 and MDM2 transcription in OVCAR3 but not MCF7 xenografts. A significantly increased population is also found in G0/G1 phase, supporting proliferative arrest upon ReACp53 administration in vivo[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 (0.96 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: ≥ 2.5 mg/mL (0.96 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 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Animal Administration
[1]

Mice[1]
In the minimal residual disease model, three cohorts of mice (n=3) are injected with a matrigel/OVCAR3 (p53 mutant) suspension on one flank and with a matrigel/MCF7 (WT p53) suspension on the other flank. Treatment is started the same day. In both models, the treatment phase consist of three weeks of daily IP injections with 15 mg/kg of ReACp53, sequence-scrambled control peptide or vehicle alone[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.
