Multi-omics integration identifies ganoderic acid A as a TNFα inhibitor for treating sepsis-related liver injury

Abstract: Ganoderic acid A (GAA), a major bioactive triterpenoid from Ganoderma lucidum, is known for its anti-inflammatory effects; however, its precise molecular targets in sepsis-related liver injury (SRLI) remain unclear. Integrating network pharmacology and transcriptomic analysis, we identified Tumor Necrosis Factor-alpha (TNFα) as a primary candidate target. Subsequent biophysical validation using surface plasmon resonance (SPR) and molecular dynamics (MD) simulations confirmed that GAA directly binds to TNFα. Functionally, this interaction inhibits the TNFα/NF-κB signaling axis, thereby suppressing macrophage M1 polarization and ameliorating liver injury in vitro and in vivo . This study identifies TNFα as a primary candidate target of GAA, providing a mechanistic basis for its hepatoprotective effects and therapeutic potential.
