Area of Science:

  • Oncology
  • Molecular Biology
  • Drug Discovery

Background:

  • The p53 tumor suppressor is crucial in cancer, and its activation has therapeutic potential.
  • Current cancer therapies often rely on DNA damage to activate p53.
  • Non-genotoxic activation of p53 offers possibilities for long-term and prophylactic cancer treatments.

Purpose of the Study:

  • To establish a screening protocol for identifying p53-dependent transcriptional activators.
  • To discover novel non-genotoxic compounds that activate the p53 pathway.
  • To explore potential clinical applications and new molecular pathways regulating p53.

Main Methods:

  • Development of a simple protocol for screening small compound libraries.
  • Identification and characterization of compounds activating p53-dependent transcription.

  • Focus on non-genotoxic activators.

    • Main Results:

    • Successfully established a screening protocol for p53 activators.
    • Identified several small compounds that activate p53-dependent transcription.
    • Discovered non-genotoxic activators with potential clinical interest.

    Conclusions:

    • The developed screening protocol is effective for identifying p53 activators.
    • Non-genotoxic p53 activators represent promising candidates for cancer therapy.
    • This approach may uncover novel p53-activating compounds and regulatory pathways.
