[FOXO3a signaling pathway in prostate cancer: Progress in studies].

FOXO3a is an important member of the FOXO subfamily of Forkhead transcription factors, which plays an important role in promoting cell apoptosis, inducing cell cycle arrest, inhibiting cell proliferation and suppressing tumor metastasis through phosphorylation, ubiquitination-mediated degradation and microRNA. Studies show that upregulated expression of FOXO3a can inhibit the growth of PCa cells. This review summarizes the advances in the studies of the FOXO3a signaling pathway in PCa, aiming to provide some new ideas on the clinical diagnosis and targeted therapy of the malignancy.
