Are Your Telomeres In Trouble?

Living in the 21st century affords you many luxuries. High-speed computers… cell phones… air conditioning and LCD TVs. But the chemicals and industrial solvents that make them possible are poisonous. We’re now floating in a sea of space-age, lab-created, synthetic molecules. And they’re flowing through your blood as you read this letter. They’re a part of life today, and we now have a new way of measuring their effect. One of the things that happened is the environment is causing your telomeres to shorten. Let me give you the example of the number-one risk factor for heart disease – high homocysteine levels.1 High homocysteine is a way to measure the inflammation that’s going on inside your body that’s being caused by all these foreign substances. High homocysteine then does more damage by blocking blood flow across your body and damaging the lining of your arteries. And most doctors know nothing about another damaging effect of high homocysteine. It shortens your telomeres. High homocysteine in your blood can triple the speed at which your telomeres shorten.2 One of the reasons homocysteine has such a damaging effect on these tiny tips to your DNA is that homocysteine cuts off telomerase. Telomerase is the enzyme your body uses to rebuild the telomere. So the environment is giving you a double whammy. First homocysteine shortens telomeres, then it cuts off the enzyme your body uses to repair the damage. Short telomeres are so...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an as...

Conclusion In summary, this is the first study to show that BFR exercise did not augment EPC response to exercise, and in fact blunted the EPC response to low load unilateral KE exercise in young, healthy males. Ethics Statement This study was carried out in accordance with the recommendations of Edinburgh Napier University Research and Ethics Governance Committee. The study was ethically approved by Edinburgh Napier University Research and Ethics Governance Committee. All participants gave written informed consent in accordance with the Declaration of Helsinki. Author Contributions MR, RM, AP, CW, GF-J designed the s...

This study defines a new clinically relevant concept of T-cell senescence-mediated inflammatory responses in the pathophysiology of abnormal glucose homeostasis. We also found that T-cell senescence is associated with systemic inflammation and alters hepatic glucose homeostasis. The rational modulation of T-cell senescence would be a promising avenue for the treatment or prevention of diabetes.

Raised blood pressure with age, hypertension, is a major downstream consequence of low-level biochemical damage and cellular dysfunction, converting it into high-level structural damage in the body and brain. Hypertension is an important proximate contributing cause of ultimately fatal age-related conditions of the cardiovascular system, kidneys, brain, and lungs, among others. Pressure damage in delicate tissues degrades function in many organs, particularly in the central nervous system where there is little to no regeneration capable of reversing that damage. More subtly, hypertension also causes heart muscles to enlarg...

This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships...

In conclusion, we found a gradient of increasing blood pressure with higher levels of BMI. The fact that this gradient is present even in the fully adjusted analyses suggests that BMI may cause a direct effect on blood pressure, independent of other clinical risk factors.
