Suppressive effects of nobiletin on hyperleptinemia and colitis-related colon carcinogenesis in male ICR mice.

abstract：:Reactive oxygen species (ROS) are a major cause of cellular injury in an increasing number of diseases, including cancer. Most ROS are created in the cell through normal cellular metabolism. They can be produced by environmental insults such as ultraviolet light and toxic chemicals, as well as by the inflammatory proc...
