Oats are often touted for boosting heart health, but scientists warn that the grain and its products might need closer monitoring for potential mold contamination. They report in ACS’ Journal of Agricultural and Food Chemistry that some oat-based breakfast cereals in the U.S. contain a mold-related toxin called ochratoxin A (OTA) that’s been linked to kidney cancer in animal studies. The findings could have implications for consumer health.
As we age, the stem cells in all tissues of our body are depleted or fail to function efficiently. This is what drives the age-associated decline in tissue function and the onset of age-related diseases such as cancer. The loss of stem cells is thought to be predominantly driven by accumulative damage to the DNA of stem cells. However, the source of this DNA damage in stem cells has previously been unclear. In a study just published in the journal Nature, scientists at the Deutsches Krebsforschungszentrum (DKFZ) Heidelberg and at the Institute for Stem Cell Technology and Experimental Medicine (HI-STEM gGmbH) have uncovered that environmental stress is a major factor in driving DNA damage in adult hematopoietic stem cells. Repeated exposure to such stress causes accelerated tissue aging and probably cancer.
