Scientists have shown that stressful situations can affect DNA in the bone marrow even two hours after the onset of stress. This damage can occur even when olfactory stress cues are used, which is an important finding. The press service also noted that the study revealed mechanisms that link the activation of various parts of the brain, the release of stress hormones and the disruption of the genome structure.
According to scientists, it was previously believed that short-term stress not exceeding two hours does not have a significant effect on the state of DNA. However, their study in mice using stress-induced chemosignals revealed genomic destabilization only after a short time.
