Donations of blood: Protects regular donations from blood cancer? New study reveals exciting knowledge!

A new study by the Francis Crick Institute in London has shown remarkable knowledge about the effects of regular blood donations on the genetic health of blood donors. Researchers discovered that frequent blood donations are associated with genetic changes in blood stem cells that can potentially reduce the risk of developing blood cancer. The analysis, which is revealed on health -like male donors over 60, revealed subtle genetic differences in the stem cells of regular donors that are not associated with a high risk of cancer. This suggests that stem cells can benefit from the blood donation process in their genetic diversity, such as "https://www.oe24.at/welt/aktuelle-studie-blutspenden-sollen-krebs-riskominimieren/626501818"> Oe24.at

In addition, an accompanying study by the DKFZ showed that blood stem cells experience special mutations such as those in the DNMT3A gene in the process of "clonal blood formation", which makes the cells more adaptable, especially after blood loss. However, these mutations do not seem to have a negative impact on general blood formation, but rather support the renewal of the blood cells by the hormone erythropoietess (EPO), which is increased more after a donation. According to the research manager Darja Karpova, the body is a positive reaction to the stress of blood loss without increasing the risk of diseases such as leukemia, explains dkfz.de

The results of these studies could not only expand the understanding of the development of blood cancer, but also positively evaluate the practice of donating blood. In particular, the exact mechanisms of how blood donations influence the formation of mutated stem cells and at the same time regenerate the blood cells stand for future research on the scientists' agenda. It is planned to validate the study results with a larger sub -group, including female donors, to obtain more comprehensive data.
