Disrupted sleep accelerate cancer growth in mice

The Huffington Post reports that a mouse study published in Cancer Research suggests that “disrupted sleep could accelerate cancer growth due to its negative effects on the immune system.”

In the study, investigators “found that … well-rested mice had more immune system cells called M1-type tumor-associated macrophages (TAMs), which are known to promote the immune system and stop cancer cells.”

Comparatively, “sleep-disrupted mice had more immune cells called M2-TAMs, which are known to actually hinder the immune system and promote tumors through blood vessel growth.”

In a University of Chicago Press Release, study researcher Dr. David Gozal, chairman of pediatrics at the University of Chicago Comer Children’s Hospital, said, “This study offers biological plausibility to the epidemiological associations between perturbed sleep and cancer outcomes.”

The bottom line, according to Dr. Gozal? “The take home message is to take care of your sleep quality and quantity like you take care of your bank account.”
