Telomeres have the potential of being the cellular clock for the production
of hormones and enzymes over the course of aging as demonstrated when the
introduction of hTRT allows the cell to express a phenotypically youthful
state. Additional research showing telomeres to be involved in the
transcriptional silencing of various genes suggest the mechanism by which
this could occur.
As of this date, however, this is by no means clear and various other
processes are likely involved in control of the endocrine system.
As most readers of this group know, I am posting a series on the telomeric
theory of aging and am at the point of writing on related aging research.
I have a few references to aging and the endocrine system and have done a
Medline search on the subject. I am not sure if I have found the most
significant studies in this area. So if anyone knows the cites for any good
studies into research into aging and the endocrine system they would be
helpful in my series.
Thanks in advance for any help provided!
