Targeting Proliferating Cell Nuclear Antigen (PCNA) as an Effective Strategy to Inhibit Tumor Cell Proliferation

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• Highly proliferating cells are a hallmark of aggressive tumors, necessitating targeted therapeutic strategies.
• Proliferating Cell Nuclear Antigen (PCNA) is crucial for DNA metabolism, cell survival, and potentially energy pathways like glycolysis.
• PCNA's central role makes it an attractive target for novel anti-cancer therapies.

Purpose of the Study:

• To review the current state of development for agents targeting Proliferating Cell Nuclear Antigen (PCNA).
• To discuss the application of PCNA-targeting agents in various tumor cell lines and preclinical animal models.
• To highlight the potential of PCNA as a therapeutic target in oncology.

Main Methods:

• Review of existing literature on small molecules and peptides designed to target PCNA.
• Analysis of studies evaluating the efficacy of PCNA-targeting agents in different cancer cell lines.
• Examination of data from animal model systems investigating PCNA-targeted therapies.

Main Results:

• Development of small molecules and peptides that bind to PCNA or compete with its interacting partners.
• Demonstration of PCNA-targeting agents' effects on DNA replication, repair, and cell survival.
• Evidence of therapeutic potential in preclinical cancer models.

Conclusions:

• Targeting PCNA is a viable strategy for chemotherapy against highly proliferating malignancies.
• Ongoing research focuses on developing effective PCNA inhibitors for clinical application.
• PCNA-targeting agents show promise in preclinical studies for various cancer types.
