摘要: Ethnopharmacological relevance: Pulmonary fibrosis (PF), a major fatal complication of calf pneumonia, is classified in traditional Chinese medicine as qi stagnation and blood stasis syndrome. The classic formula Danggui Buxue Decoction (DBD) effectively treats PF by replenishing qi and blood and promoting circulation, though its precise mechanism remains unclear. Aims: To elucidate DBD's anti-PF mechanism via apoptosis regulation using network pharmacology and in vitro studies. Methods: HPLC was employed to analyze the active components of DBD. Network pharmacology identified core targets and pathways. Subsequently, a TGF-β1-induced embryonic bovine lung (EBL) cells model was established, including the control, TGF-β1, and DBD treatment groups (50, 250, and 500 μg/mL). DBD's effects were evaluated through proliferation, apoptosis, and migration (scratch) assays. Key targets were validated via Western blot, qRT-PCR, and immunofluorescence. Results: Five active compounds in DBD were identified by HPLC. Sixty-seven PF-related targets, with EGFR, CASP3, Bcl-2, Bax, TNF, IL6, IL-1β, HIF-1α, and AKT1 as core targets, were revealed by Network pharmacology. The PI3K/AKT, FOXO1, and apoptosis signaling pathways are the major pathways. Molecular docking demonstrated strong binding between DBD compounds (calycosin-7-glucoside, chlorogenic acid, ferulic acid, formononetin, ononin) and AKT1/Bax/Bcl-2. Therefore, the PI3K/AKT, FOXO, and apoptosis pathways were proposed as potential therapeutic targets for subsequent experimental validation. In vitro studies demonstrated that DBD promotes apoptosis through PI3K/AKT pathway inhibition, as shown by the downregulation of α-SMA, P-PI3K, P-AKT, P-FOXO1, and Bax, along with the upregulation of Bcl-2 and E-cad. Conclusion: DBD alleviates PF by inhibiting PI3K/AKT/FOXO1-mediated apoptosis, supporting its therapeutic potential.
