Chronic stress accelerates premature aging by shortening DNA telomeres. A wide range of studies have shown that the stress caused by things like: untreated depression, social isolation, long-term unemployment, anxiety attacks... can speed-up the aging process by shortening the length of each DNA strand.
In the present study we investigated the alterations in the telomere structural changes including the length shortening and subtelomeric methylation status and in telomerase activity under various levels of hypoxia to assess the effects of hypoxia on the telomere maintenance of human vascular endothelial cells.
