BACKGROUND: Prostate cancer (PCa) is one of the most common malignancies among middle-aged and elderly men. It exhibits persistently high global incidence and mortality rates. Given the limitations of conventional treatments, novel therapeutic approaches are urgently needed. Natural products offer distinct advantages, including low cost, reduced risk of drug resistance, and fewer side effects. Owing to their multi-component, multi-target, and multi-pathway regulatory properties, natural products have shown significant promise in PCa treatment.
PURPOSE: This review investigates the regulatory effects of natural products on cellular autophagy and examines their roles in the initiation and progression of PCa. By proposing a novel natural product-autophagy-PCa axis, this study provides a framework for translating experimental findings into clinical practice and identifying potential therapeutic strategies for PCa.
METHODS: A systematic review was conducted on cellular autophagy mechanisms and their association with PCa. Comprehensive searches were performed in authoritative databases, up to September 2025. Keywords included 'PCa', 'castration-resistant PCa', 'autophagy', 'autophagic flux', 'selective autophagy','macroautophagy','natural products', 'active compounds', 'traditional Chinese medicine (TCM) formulas', and 'TCM'. Additionally, this review explores single Chinese medicinal herbs, natural small-molecule compounds, and traditional Chinese medicinal formulae capable of regulating autophagy to improve PCa outcomes.
RESULTS: Multiple natural products derived from plants, animals, and microorganisms effectively target cellular autophagy, thereby inducing apoptosis, inhibiting cell proliferation, migration, and invasion, delaying PCa progression, and demonstrating promising therapeutic effects. This review systematically outlines the origins, pharmacological actions, mechanisms, efficacy, and safety profiles of these natural products, highlighting their potential clinical benefits and providing a holistic perspective on their characteristics.
CONCLUSIONS: This study fills existing gaps in the systematic characterisation of the relationship between autophagy and PCa, as well as in the development of natural product-based therapeutic strategies. It aims to offer more diverse treatment options to patients and contribute to advancements in PCa therapy.
