Au Catalyzing Control Release NO in vivo and Tumor Growth-Inhibiting Effect in Chemo-Photothermal Combination Therapy
INTRODUCTION: Aim to obtain a NO donor that can control released NO in vivo with the high efficacy of tumor suppression and targeting, a nanoplatform consisting of FA-Fe(3)O(4)@mSiO(2)-Au/DOX was constructed. METHODS: In vitro, the nanoplatform catalyzed NO’s release with the maximum value of 4.91 μ...

description | INTRODUCTION: Aim to obtain a NO donor that can control released NO in vivo with the high efficacy of tumor suppression and targeting, a nanoplatform consisting of FA-Fe(3)O(4)@mSiO(2)-Au/DOX was constructed. METHODS: In vitro, the nanoplatform catalyzed NO’s release with the maximum value of 4.91 μM within 60 min at 43°C pH=5.0, which was increased by 1.14 times when the temperature was 37°C. In vivo, 11.7 μg Au in the tumor tissue was found to catalyze S-nitrosoglutathione continuously, and 54 μM NO was checked out in the urine. RESULTS AND DISCUSSION: The high concentration of NO was found to increase the apoptotic rate and to reduce tumor proliferation. In the chemo-photothermal combination therapy, the tumor inhibition rate was increased up to 94.3%, and Au’s contribution from catalyzing NO release NO was 8.17%. |
