It may be possible to suppress the proliferation of cancer cells by running

ByRaúl González

Immune cells known for suppressing proliferation of cancer cells are "Natural killer cellsHowever, experiments with mice showed the possibility of natural killer cells becoming active and suppressing the growth of tumor cells such as cancer cells by exercise such as running.

University of Copenhagen turned the mouse and run it in a car and investigated the influence of exercise on immune system attacking cancer cells. As a result, it was found that the immune system of mice that ran between 4 km and 7 km every night became active, prevented the growth of new tumors, and found that the growth of existing tumors could be suppressed by 60% at the maximum. Pernille Hojman of the University of Copenhagen said, "I was able to demonstrate for the first time that exercise can directly control tumor growth rate."

The research team conducted experiments on the relationship with exercise using mice suffering from five types of cancer, such as skin, lung, and liver. By releasing adrenaline by exercise, the immune system which sends out natural killer cells fighting cancer cells with blood flow is stimulated, so it is possible to suppress tumor growth. Also, from the muscles during exerciseInterleukin-6(IL-6) has been released and it is known that it instructs natural killer cells to attack the tumor.

Although it has been pointed out that natural killer cells are activated by exercise so far, it has been shown for the first time that stress hormone released by exercise gives instructions to attack cancer cells . Whether it has the same effect on humans has not been studied yet, but exercise says that it can prevent colorectal cancer and breast cancer after menopauseresearch resultHojman's research team will examine the movement pattern of cancer patients and investigate whether there is the same effect as this mouse.
