Flow cytometry analysis revealed that MAE pretreatment significantly attenuated intracellular Ca<sup>2+</sup> accumulation caused by oxidative stress.

Protein-protein interaction (PPI) network analysis demonstrated a highly interconnected and functionally enriched network among these targets, indicating coordinated regulation of calcium signaling pathways. Molecular docking studies supported these findings by showing strong binding affinities of MAE's isoquinoline alkaloids, particularly tetrahydropalmatine, to SERCA (ATP2A1) and IP3R (ITPR1).
