摘要
Hepatocellular carcinoma (HCC) is a common high-mortality malignancy which still needs efficient treatments. HCC patients undergoing extrahepatic metastases are mostly with unsatisfactory prognosis. Therefore, specific attention has been paid to extrahepatic HCC metastasis. We integrated Sorafenib (Sor) and glucose oxidase (GOx) into a N-acetyl-galactosamine (GalNAc) modified zeolitic imidazolate framework (ZIF-8), designated as SG@GR-ZIF-8, for targeted bimodal therapies of chemotherapy and starvation therapy against HCC. The hepatic delivery of SG@GR-ZIF was mediated by the specific recognition of GalNAc residues with asialoglycoprotein (ASGPR) on the liver cell surface. Sor is a clinically approved anti-proliferation and anti-angiogenesis drug for advanced HCC treatment. GOx can efficiently induce cell death and disturb malignant progression by suppressing glucose supply of cancer cells, which is highly associated with metabolic rewiring in metastasis. The nano-formulation exhibit significant anti-metastatic HCC activity against C5WN1 cells, a liver cancer stem cell-like cell line with tumorigenicity and pulmonary metastasis activity. In a subcutaneous C5WN1-tumor carrying mouse model, SG@GR-ZIF exhibits potent synergistic anti-tumor activity with a tumor inhibition rate of 89% and a prolonged survival status. The growth and pulmonary metastasis of HCC in an orthotopic mouse model of HCC was remarkably suppressed in SG@GR-ZIF treated group. The therapeutic strategy targeting energy supply combined with first-line treatment holds great promise for the future treatment of metastatic HCC. SG@GR-ZIF, a N-acetyl-galactosamine modified metal-organic framework carrying Sorafenib and glucose oxidase, was fabricated for treating metastatic hepatocellular carcinoma (HCC). Sorafenib is an anti-proliferation and anti-angiogenesis drug for advanced HCC treatment. Glucose oxidase blocks energy demand in HCC metastasis by depleting glucose. C5WN1 was used for therapeutic evaluations as a liver cancer stem cell-like cell line with tumorigenicity and pulmonary metastasis activity. In subcutaneous C5WN1-tumor bearing mice, SG@GR-ZIF exhibited a tumor inhibition rate of 89% and prolonged survival period. In orthotopic C5WN1-tumor carrying mice, the growth and pulmonary metastasis of hepatocarcinoma was remarkably suppressed by SG@GR-ZIF. Together, this study suggests the great potential of synergistic chemo/starvation therapy mediated by SG@GR-ZIF for treating metastatic HCC.
