Targeted regulation of autophagy using sorafenib-loaded biomineralization nanoenzyme for enhanced photodynamic therapy of hepatoma.

ABSTRACT: Sorafenib (SF), a multi-targeted tyrosine kinase inhibitor, serves as a primary therapeutic modality for advanced liver cancer. Nonetheless, its clinical efficacy is hindered by various obstacles, such as limited bioavailability and inadequate accumulation. This study introduces a novel biomimetic mineralization enzyme, known as BSA@Pt/Ce6/SF@M (PCFM). The PCFM incorporates platinum (Pt) as a catalytic agent, SF as a molecular-targeted therapeutic agent, and Ce6 as a photosensitizer within liver cancer cell membranes. This strategy enables the combination of various anti-tumor treatments, such as photodynamic therapy (PDT) and autophagy induction, leading to increased bioavailability of SF and achieving a multidimensional synergistic anticancer effect. The PDT effect produced by Ce6 in PCF
