Mutated tumor suppressor protein p53 can aggregate, promoting cancer chemoresistance. This review explores anti-p53 aggregation molecules and autophagy as potential cancer therapies targeting protein aggregation.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- The tumor suppressor protein p53 is frequently mutated in over 50% of human cancers.
- Mutations often lead to oncogenic gain of function (GOF), promoting p53 aggregation via phase separation and transition.
- p53 aggregation contributes to chemoresistance, complicating cancer treatment.
Purpose of the Study:
- To review novel therapeutic strategies targeting p53 aggregates in cancer.
- To classify anticancer molecules that inhibit p53 aggregation.
- To explore the role of autophagy in degrading aggregated p53.
Main Methods:
- Literature review of studies on p53 aggregation and anticancer agents.
- Classification of anti-p53 aggregation molecules into four categories.
- Discussion of autophagy as a potential therapeutic pathway.
Main Results:
- Identified four categories of molecules with anti-p53 aggregation properties: thiol alkylating agents, designed peptides, chaperone-based inhibitors, and miscellaneous compounds.
- Highlighted the potential of autophagy for degrading aggregated p53.
- Reviewed strategies to disrupt p53 aggregates for cancer regression.
Conclusions:
- Targeting p53 aggregates represents a promising strategy for cancer therapy.
- Cancer can be viewed as a protein aggregation disease, amenable to anti-aggregation treatments.
- Further research into anti-p53 aggregation molecules and autophagy is warranted.
