Sound sleep can save you from cancer
A new research has shed light on how a good night sleep can save one from cancer.
Washington: A new research has shed light on how a good night sleep can save one from cancer.
The study conducted at German Cancer Research Center suggested that under conditions of stress, such as during chronic blood loss or infection, hematopoietic stem cells are driven into a state of rapid cell division in order to produce new blood cells and repair the damaged tissue.
Dr. Michael Milsom, leader of the study, said their theory was that this state of dormancy protected hematopoietic stem cells from DNA damage and, therefore, protects them from premature aging.
Milsom further added that they believe this model perfectly explains the gradual accumulation of DNA damage in stem cells with age and the associated reduction in the ability of a tissue to maintain and repair itself as one gets older.
Prof. Dr. Andreas Trumpp, director of HI-STEM and head of the Division of Stem Cells and Cancer at the DKFZ, said that the novel link between physiologic stress, mutations in stem cells and aging is very exciting and by understanding the mechanism via which stem cells age, we can start to think about strategies to prevent or at least reduce the risk of damaged stem cells which are the cause of aging and the seed of cancer.
