Milk consumption has been linked to improved health, with decreased risks of diabetes, metabolic syndrome, and colon cancer. Scientists found that lactoferricin4-14, a milk protein with known health effects, significantly reduces the growth rate of colon cancer cells over time by prolonging the period of the cell cycle before chromosomes are replicated. In a new study, investigators report that treatment with Lfcin4-14 reduced DNA damage in colon cancer cells exposed to ultraviolet light.
