GOF Mutant p53 in Cancers: A Therapeutic Challenge

Area of Science:

• Oncology
• Molecular Biology
• Cancer Genetics

Background:

• TP53 gene mutations are prevalent in most human cancers.
• Mutant TP53 proteins exhibit oncogenic properties, promoting tumor progression and therapeutic resistance.
• These mutants can interfere with wild-type TP53 (WTp53) function or gain new oncogenic functions.

Purpose of the Study:

• To review the mechanisms by which mutant TP53 confers chemoresistance.
• To explore emerging therapeutic strategies aimed at targeting mutant TP53 in cancer.

Main Methods:

• Literature review of studies on TP53 mutations and cancer.
• Analysis of mechanisms underlying mutant p53-mediated chemoresistance.
• Evaluation of novel therapeutic approaches targeting mutant p53.

Main Results:

• Mutant p53 proteins promote tumor growth, invasion, metastasis, and chemoresistance.
• Various strategies are being investigated to target mutant p53, including stability modulation, targeting binding partners, and restoring WTp53 function.
• These approaches aim to re-sensitize tumors to chemotherapy.

Conclusions:

• Understanding mutant TP53's role in chemoresistance is crucial for developing effective cancer therapies.
• Targeting mutant TP53 offers promising avenues for overcoming treatment resistance and improving patient outcomes.
• Further research is needed to address challenges in current therapeutic strategies.
