    Kaempferol modulates the HSP70–Beclin-1 interaction in a dose-dependent manner, influencing autophagy and chemotherapy response.

  • 2

    Low-dose kaempferol stabilizes the HSP70–Beclin-1 complex, suppressing autophagic flux and reducing chemotherapy-induced apoptosis.

  • 3

    High-dose kaempferol disrupts the HSP70–Beclin-1 complex, enhances autophagic flux, and activates AMPK/mTOR and ER stress–JNK signaling.

    In vivo, high-dose kaempferol enhances cisplatin's antitumor activity, while low-dose kaempferol diminishes it.

  • 5

    The study reveals a molecular framework for optimizing natural product dosing to leverage autophagy-based chemosensitization in cancer.
