SFN exerts multifaceted anticancer effects through the activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)–antioxidant response element (ARE) pathways, inhibition of histone deacetylases (HDACs) and hypoxia-inducible factor-1α (HIF-1α), and regulation of apoptosis and autophagy. Epidemiological studies have consistently associated cruciferous vegetable intake with reduced cancer risk, while mechanistic research has elucidated the capacity of SFN to modulate redox balance, detoxification pathways, and epigenetic processes. Recent clinical trials have further demonstrated its potential to reduce carcinogenic biomarker levels and support metabolic detoxification. This review integrates evidence from epidemiological observations, molecular mechanisms, and clinical studies to provide a comprehensive understanding of the role of SFN in cancer prevention and therapy. Finally, translational challenges, including limited bioavailability, dose optimization, and standardization of broccoli-derived preparations, are discussed as critical factors for successfully translating SFN therapies from bench to bedside.  \nKeywords: sulforaphane; chemoprevention; Nrf2–ARE pathway; epigenetic regulation; HDAC inhibition; cell death; clinical trials  \n1. Introduction  \nSulforaphane (SFN) is an aliphatic isothiocyanate derived from glucoraphanin, a major glucosinolate abundant in cruciferous vegetables such as broccoli, kale, and cauliflower. It is widely recognized as a bioactive dietary phytochemical with diverse biological activities [1] . SFN exerts pleiotropic cytoprotective, anti-inflammatory, and stress-adaptive effects by regulating redox homeostasis, mitochondrial function, immune responses, and cellular detoxification pathways, which collectively contribute to cellular stress control and homeostasis [2–7] .  \nAt a fundamental biological level, these diverse stress-adaptive effects converge on a limited number of central regulatory pathways. Among them, the nuclear factor erythroid 2-related factor 2 (Nrf2)–antioxidant response element (ARE) axis represents a principal  \nmolecular hub through which SFN orchestrates antioxidant and detoxification responses, together with the modulation of inflammatory and metabolic signaling networks, thereby enhancing cellular antioxidant capacity and detoxification systems [8] . Through engagement of these stress-response pathways, SFN has been implicated in the protection against cardiovascular, metabolic, and neurodegenerative disor","cbCaifHRteAGasDi","https://ap.wps.com/l/cbCaifHRteAGasDi","pdf",1312931,21,"English","# Introduction\n# Mechanistic Basis of SFN in Cancer Prevention and Therapy\n# Epidemiological Evidence\n# Clinical Trials and Translational Outlook\n# Translational Challenges","[{\"question\":\"How does sulforaphane exert anticancer effects at the molecular level?\",\"answer\":\"Sulforaphane activates the Nrf2–ARE pathway, inhibits HDACs and HIF-1α, and regulates apoptosis and autophagy, thereby coordinating antioxidant, detoxification, and stress-response processes.\"},{\"question\":\"What evidence links cruciferous vegetable intake to cancer risk reduction?\",\"answer\":\"Epidemiological studies consistently associate sustained consumption of cruciferous vegetables with reduced risk of multiple cancers, including lung, colorectal, prostate, and breast cancers.\"},{\"question\":\"What translational challenges limit the clinical use of sulforaphane?\",\"answer\":\"Key challenges include limited bioavailability, the need for dose optimization, and the requirement to standardize broccoli-derived preparations to enable consistent therapeutic effects.\"}]","Sulforaphane in Cancer Prevention and Therapy - A State-of-the-Art Review - Epidemiological Evidence, Molecular Mechanisms, and Translational Challenges | PDF",1790107178,53]
