CD24 and Mutant p53: Emerging Therapeutic Targets in Prostate Cancer Progression.

INTRODUCTION Prostate cancer is a leading cause of cancer-related mortality in men worldwide, and the treatment of metastatic castration-resistant prostate cancer (mCRPC) remains a major clinical challenge. CD24, a glycosylated cell surface protein, plays a critical role in tumor progression and immune evasion. This review focuses on the role of CD24 in prostate cancer pathogenesis, particularly its interaction with mutant p53, and explores potential therapeutic implications.

METHODS Through a systematic search of the PubMed, Web of Science, and Embase databases (2015-2025), using the following structured search terms: (CD24 OR "CD24 antigen") AND ("prostate cancer" OR "prostatic neoplasms") AND ("mutant p53" OR "TP53 mutation") AND ("targeted therapy" OR immunotherapy), relevant studies were identified and screened according to PRISMA guidelines.

RESULTS CD24 overexpression was significantly associated with high Gleason scores, metastasis, and poor prognosis. Mechanistically, CD24 promotes tumor progression by destabilizing p53 through the disruption of ARF-NPM interactions and by synergizing with mutant p53. Preclinical studies indicate that therapies targeting CD24, such as CAR-T cells and nanoparticle-based drug delivery systems, demonstrate potent anti-tumor effects.

DISCUSSION The CD24-p53 axis is amplified in mCRPC and interacts with androgen receptor signaling, while tumor microenvironment factors further enhance treatment resistance.

CONCLUSION CD24 and mutant p53 represent promising therapeutic targets in metastatic castration-resistant prostate cancer (mCRPC). Translating these targeting strategies into clinical practice may help overcome current therapeutic challenges and improve patient outcomes.
