CDK2 and breast carcinoma: Network pharmacological analysis and molecular docking technology demonstrated that SACG reversed breast cancer resistance through an intricate multi-component (flavonoids/alkaloids), multi-target (AKT1/TNF/CDK2), and multi-pathway (PI3K-AKT/FoxO/MAPK) synergistic mode of action, with the PI3K-AKT pathway acting as the core regulator.
