Review Frames Liquid-Liquid Phase Separation as Key Target in Tumor Evolution

A scientific review published in Molecular Cancer proposes a conceptual and translational framework that links molecular regulation, condensate dynamics, material-state transitions, tumor phenotypes, and therapeutic vulnerabilities. The paper positions liquid-liquid phase separation as a unifying framework for understanding tumor evolution and as a programmable therapeutic principle for next-generation precision oncology.

Liquid-liquid phase separation enables biomolecules to form dynamic membraneless condensates that organize biochemical reactions in space and time. In cancer, this adaptive organizational principle is frequently hijacked, transforming reversible regulatory assemblies into persistent hubs that sustain malignant cell states. The authors discuss how post-translational modifications and environmental cues reshape phase behavior, driving the formation and persistence of these hijacked regulatory assemblies.

The review examines how aberrant liquid-liquid phase separation coordinates cancer-associated programs, placing particular emphasis on metabolic reprogramming, immune regulation, autophagy, deoxyribonucleic acid damage repair, and therapy resistance. Beyond conventional tumor-intrinsic condensates, the authors highlight two relatively underexplored dimensions of phase separation biology: material-state transitions toward gel- or solid-like states, and gut microbiota–associated phase biology linking microbial signals to host condensate-forming pathways. In analyzing these connections, the review distinguishes experimentally supported interactions from indirect or incompletely validated microbiota-mediated effects on host phase behavior.

Finally, the review discusses therapeutic opportunities arising from liquid-liquid phase separation biology in oncology. These include strategies to disrupt oncogenic condensates, reprogram phase behavior, induce cytotoxic or immune-favorable condensate states, and engineer condensate-based delivery or signaling platforms. By framing phase separation as both a driver of malignant states and an actionable target, the authors present liquid-liquid phase separation as an adaptable, programmable foundation for precision cancer interventions.
