Arsenic trioxide induces autophagic cell death in osteosarcoma cells via the ROS-TFEB signaling pathway

Osteosarcoma is a common primary malignant bone tumor, the cure rate of which has stagnated over the past 25-30 years. Autophagy modulation has been considered a potential therapeutic strategy for osteosarcoma, and previous study indicated that arsenic trioxide (ATO) exhibits significant anti-carcinogenic activity. However, the ability of ATO to induce autophagy and its role in osteosarcoma cell death remains unclear. In the present study, we...
