Summary
This narrative review synthesises evidence on sulforaphane (SFN), an isothiocyanate compound abundant in Brassica vegetables such as broccoli, as a putative chemopreventive agent. The authors outline SFN's multifaceted cellular mechanisms—including anti-inflammatory signalling, apoptosis induction, and epigenetic histone modulation—that may underpin its capacity to disrupt carcinogenic pathways. The review integrates preclinical findings and discusses emerging interest in SFN's effects on cancer stem cells, positioning cruciferous vegetable consumption as a potential dietary strategy for cancer risk reduction.
Regional applicability
Findings are applicable to United Kingdom dietary guidance and public health messaging, where promotion of vegetable consumption, particularly cruciferous varieties, aligns with cancer prevention recommendations. The mechanistic insights are derived from laboratory and preclinical studies and would require translation to human epidemiological or intervention data to inform UK-specific dietary policy.
Key measures
Mechanistic pathways of sulforaphane action; anti-inflammatory activity; pro-apoptotic effects; histone modulation; cancer stem cell inhibition
Outcomes reported
The review examined the chemopreventive mechanisms of sulforaphane (SFN), an isothiocyanate compound derived from glucosinolates in cruciferous vegetables. Key outcomes included documentation of SFN's anti-inflammatory, pro-apoptotic, and histone-modulating effects, as well as its potential activity against cancer stem cells.
