Telomere Testing: Everything You Need To Know About A Cutting - Edge New Longevity Test That Tells You Your Cellular Age.
After each new replication the telomeres shorten until they reach a critical length when they stop dividing, begin to «age» and ultimately die.4 Scientific laboratories like SpectraCell now provide
telomere testing as «a window into your cellular age.»
The most important question for people taking
the telomere test, though — whether you can do anything about your shrinking telomeres, if indeed they cause disease — is the one that still needs the most research.
The personal
telomere test, like the personal genome test, is coming at a time when we've still got many more questions about what it will reveal than solid answers.

telomere length.
To evaluate whether the experimental treatment is safe and whether it might be able to reduce frailty, Maharaj plans to run a battery of baseline
testing on each clinical trial participant before they get their first infusion of young plasma and then monitor their changes for two years: That means cognitive exams, questionnaires about their quality of life and their indicators of frailty, and
tests to measure biomarkers he believes are linked with aging, such as
telomere lengths and DNA methylation.

Telomeres and Longevity:
Testing an Evolutionary Hypothesis.»
«Our findings reveal a critical role for
telomere length in a mouse model of age - dependent human disease,» said first author Christina Theodoris, an MD / PhD student in the laboratory of Deepak Srivastava, MD. «This model provides a unique opportunity to dissect the mechanisms by which
telomeres affect age - dependent disease and also a system to
test novel therapeutics for aortic valve disease.»
To rigorously
test for any non-TMM effects of TERT requires confidence that any phenotypic abnormalities are not related to
telomere shortening per se.
A direct in vivo
test for deleterious effects of the deletion of TERT that do not involve the critical shortening of
telomeres per se is somewhat challenging.
