Abstract
studies demonstrated that PEG-MSN@ATO enhanced the antitumor efficacy by inducing apoptosis and ROS production, inhibiting tumor cell proliferation and metastasis, and activating antitumor immunity within the TME. PEG-MSN@ATO also reduced the system toxicity of ATO by controlling the pH-trigger release in the tumor site. These results indicate that the PEG-MSN@ATO represents a promising drug delivery platform for reducing toxicity and enhancing the therapeutic efficacy of ATO against LC.
