CellChat Hotspot identifies a loss of HSPG pathway communication—specifically HSPG2 DAG1 between CALB1+ and stromal cells—in stage II colon cancer recurrence.
- Why it matters: Global CellChat-style interaction networks can be hard to interpret and may include biologically irrelevant signals, limiting confidence in inferred communication patterns.
- What they did: The framework combines gene set enrichment with context-driven filtering to select functionally relevant genes and cells before communication inference, then validates results using spatial transcriptomics.
- The result: In stage II colon cancer, non-recurrent patients show immune process enrichment, while recurrent cases show invasion/metastasis pathways and near absence of HSPG2 DAG1 in spatial data.
