  "account": "Aggressive cellular migration drives cancer invasion and metastasis, yet the molecular drivers of highly migratory tumor cells are unclear. In head and neck squamous cell carcinoma (HNSCC), metastasis correlates with poor prognosis, driving the need for methods that link cell migration to their underlying mechanisms. Behavior-coupled single-cell sequencing (BC-seq) is introduced as a live-cell imaging-guided transcriptomic platform that can identify, isolate, and profile individual cells based on their migratory behavior in real-time. BC-seq was applied to 10 HPV-negative oral squamous cell carcinoma (OSCC) samples, revealing distinct fast-migrating cells (FMCs) and slow-migrating cells (SMCs). Transcriptional programs associated with aggressive migration were identified in FMCs. Mechanistically, BC-seq uncovered cholesterol-regulated signaling pathways and trafficking proteins involved in actin cytoskeletal remodeling and motility, including SREBP2, STARD4, Cavin1/3, and VEGFR2. Disruption of STARD4-mediated cholesterol trafficking or Cavin1/3-dependent VEGFR2 nuclear translocation impaired cell migration, linking cholesterol metabolism to migratory machinery. The team then investigated whether molecular programs associated with aggressive migration were reflected in clinical outcomes. A 15-gene expression signature derived from FMCs accurately predicted distant metastasis in an independent OSCC cohort, with 83.6% accuracy, surpassing conventional clinicopathological risk stratification. The study concludes that BC-seq effectively integrates dynamic cellular behavior with single-cell transcriptomics to uncover mechanisms of aggressive migration and clinically relevant molecular signatures.",
  "summary": "Aggressive cellular migration underlies cancer invasion and metastatic dissemination, yet the molecular programs defining highly migratory tumor cell states remain poorly characterized. In head and neck squamous cell carcinoma (HNSCC), metastatic progression is associated with poor clinical outcome, motivating method developments that link migratory behavior to underlying mechanisms.
