Sulforaphane as a Multi-Scale Mechano-Modulator in Cancer: An Integrative Perspective

Cancer progression is driven not only by biochemical signals but also by abnormal physical forces within a stiffened tumor microenvironment. This review re-examines the anticancer compound sulforaphane (SFN) through the integrative lens of tumor biomechanics. We propose SFN functions as a "mechano-modulator," whose pleiotropic effects converge to disrupt pro-invasive mechanotransduction. SFN targets key force-sensitive pathways (e.g., YAP/TEAD, Rho/ROCK), destabilizes invasion machinery (cytoskeleton, invadopodia), and promotes tissue-level changes such as extracellular matrix remodeling. While preclinical evidence for this mechano-modulatory role is compelling, this perspective also highlights the critical need for clinical validation and discusses the key translational challenges. By systematically linking SFN's molecular actions to the biophysics of tumor progression, this synthesis provides a novel framework for understanding its efficacy and outlines a rational path for its future development as a mechano-inspired therapeutic.
