Antioxidant Effect of Hydrogen Nanobubble Contributes to Suppression of Tumor Cell Growth

The antitumor effect of hydrogen nanobubble was evaluated in vitro and in vivo. Cancer cell growth was inhibited in the hydrogen nanobubble-containing medium compared to the non-containing medium (in vitro). Tumor growth was significantly suppressed in the middle stage of transplantation (in vivo). We reported that hydrogen nanobubbles is a ROS scavenger, therefore apoptosis due to ROS reduction may be induced in these results.
