ROS is not only tightly associated with 35 chronic inflammation and tissue aging but also regulates cell proliferation and cell signaling. Yet 36 critical questions remain in the field, such as detailed genome-environment interaction on aging 37 regulation, and how ROS and chronic inflammation alter genome that leads to aging.
