Implication

In vitro and bioinformatic study demonstrates apigenin reduces pyroptotic injury in lung adenocarcinoma cells, indicating potential therapeutic value targeting inflammatory cell death pathways.

Key Points

  • To examine whether apigenin mitigates cellular injury and pyroptosis-associated signaling in lung adenocarcinoma cells and identify potential underlying molecular targets.
  • Treated an in vitro cellular injury model of A549 lung adenocarcinoma cells with apigenin and evaluated cell morphology, viability via CCK-8 assays, and pyroptosis markers.
  • Applied network pharmacology, molecular docking, and molecular dynamics simulations to predict candidate drug targets.
  • Analyzed TCGA and GEO datasets to identify pyroptosis-related lung adenocarcinoma subtypes and construct a validated prognostic risk signature.
  • Apigenin partially restored cell viability, alleviated morphological damage, and decreased levels of GSDMD-N, caspase-1, IL-1β, AIM2, ASC, and TNF-α/NF-κB pathway proteins.
  • Computational simulations prioritized TNF and AIM2 as primary targets and predicted a stable interaction between apigenin and TNF.
  • Bioinformatic analyses established a pyroptosis-related gene signature that successfully stratified patient survival in both training and external validation cohorts.
