Their findings indicated that baicalein’s anti-PDCoV effects exhibit multi-target and multi-pathway characteristics, potentially acting on core genes including AKT1, HSP90AA1, SRC, EGFR, CASP3, MAPK, and STAT3 to regulate the PI3K-Akt, Ras, and MAPK signaling pathways, apoptosis, viral infection, and other processes. This evidence concerns the gene CASP3 and viral infectious disease.
