Abstract
Metastasis is the most lethal form of prostate cancer, and finding new therapeutic targets remains a major clinical challenge. TP53 mutation has been identified to be involved in tumor progression and metastasis. Nevertheless, direct evidence of the role of TP53 mutation in prostate cancer metastasis and its underlying mechanism remain obscure. Herein, TP53 was found to be the most mutated gene in prostate cancer, and missense mutations were the primary mutation type based on bioinformatics data analysis. Subsequently, TP53 rs12947788 mutation site was significant in prostate cancer, and correlated with metastasis and tumor-node-metastasis (TNM) stage. Furthermore, forkhead box A1 (FOXA1), a target of TP53, was highly expressed in prostate cancer tissue, especially in TP53-mutant patients. It was also associated with patients' Gleason scores and nodal metastasis. Knockdown of FOXA1 suppressed the migration in prostate cancer cells in vitro. Our findings indicate that targeting TP53 mutation and FOXA1 might be a promising therapeutic target for prostate cancer metastasis.
