“…Glucocorticoids, the primary adrenal hormones secreted during stress, increase oxidative stress damage to neurons, in part by increasing glutamate and calcium and decreasing antioxidant enzymes (23,24). It is also notable that, in women, self-reported distress has been related to greater oxidative DNA damage (8-OH-dG) (12). Oxidative stress shortens telomeres in cells cultured in vitro (10).…”

“…Most notably, in vitro, oxidative stress can shorten telomeres and antioxidants can decelerate shortening (9,10). Perceived stress has been linked to one measure of oxidative DNA damage in leukocytes in women (11,12). Given these observed links, we hypothesized that chronic psychological stress may lead to telomere shortening and lowered telomerase function in peripheral blood mononuclear cells (PBMCs) and to oxidative stress.…”

“…A high GHQ score, which indicates poor psychological well-being, is associated with suicide attempts and psychiatric disorders such as alcoholism, major depressive episodes (20) as well as high mortality after stroke or cerebrovascular diseases (21,22). Irie et al, who examined the relationship of 8-OH-dG level, a biomarker of cancer-related oxidative DNA damage, to GHQ-12 score in female workers have found a higher 8-OH-dG level in female workers with a high GHQ-12 score, suggesting that poor psychological well-being is related to a higher risk of developing cancer due to oxidative DNA damage in females, possibly via neutrophil activation (23). Therefore, the relationships of poor psychological well-being with the subsequent development of mental and physical diseases and mortality are likely to reinforce the importance of the assessment of psychological factors, work systems and lifestyles, followed by appropriate intervention to alleviate these psychological symptoms (24).…”

“…Shortening of telomeres with stress and depression could be explainable by referencing two other bodies of research: the first relating stress and depression to changes in certain biological mediators, and the second relating changes in the same biological mediators to telomere shortening. For example, chronically stressed and depressed individuals (especially females) have increased levels of circulating oxidative stress markers (e.g., increased F2-isoprostanes, 8-hydroxy-deoxyguanosine (8-OHdG)), along with decreases in anti-oxidant enzymes, and the concentration of oxidative stress markers is directly correlated with the severity of depression (Forlenza and Miller 2006;Irie et al 2002Irie et al , 2003Tsuboi et al 2004). Additionally, depression may be associated with increased levels of pro-inflammatory cytokines (Leonard 2000;O'Brien et al 2004), although not all studies support this.…”
