Hayflick limit • The Hayflick limit: The number of
times a normal cell population will divide until cell division stops.
• The telomeres associated with each cell's DNA will get slightly shorter with each new cell division until they shorten to a critical length and cellular death or mutation result
Telomeres • Region of repetitive nucleotide
sequences (TTAGGG) at each end of the chromatid
• Protects the end of the chromosome from deterioration or from fusion with neighboring chromosomes
• Telomeres act as the cellular aging clock.
• Telomere loss is a Major Cause of Cellular Aging
Telomeres: • Telomere length is dynamic and results from
balance between factors. – Erosion (Blackburn, 1991) – Oxidative stress (Von Zglinicki, 2000) – Restoration through telomerase activity,
(Greider and Blackburn, 1985) • Telomere length remains a key feature that
indicates the viability of a cell (Blackburn, 2000).
Telomere Function • Serve as chromosome end caps to protect genomic
integrity • Prevent fusion • Prevent genomic instability • Necessary for cellular replication • Protection from cellular senescence • Protection from DNA mutations that can lead to cancer

Telomere Biology • 24,382 citations in Pub Med on February 27, 2015
regarding telomeres & telomerase. – Telomere shortening is a root cause of cellular
aging and mitochondrial degradation.
– Age related decline, dysfunction, and a shortened lifespan are all related to telomere shortening.

Telomerase Activation
• Reverses some aspects of aging in old mice – Brain, spleen and reproductive organs were
rejuvenated – Resulting in increased neurons and new viable
sperm cells. – Sense of smell returned. – None of the mice developed cancer.
• Jaskelioff M et al. Telomerase reactivation reverses tissue
degeneration in aged telomerase-deficient mice. Nature. 2011 Jan 6;469(7328):102-6.
Telomere Length Determines Cellular Age
• Somatic cells – Make up > 99% of the cells in the adult body – Have little or no telomerase and telomeres shorten as we get
older. • Telomere Length Shortening:
– Conception: Telomeres start out 15,000 base pairs (bp) long. – By Birth the embryo has divided so many times that telomere
length is down to 10,000 bp. – Over the rest of our lifetime we lose another 5,000 to 7,000 bp. – When telomere length gets to 3-5,000 bp, the genome is no
longer protected from mutations, the cell can no longer divide, becomes senescent, metabolism slows down, and the cell dies.
– Senescence-Associated Secretory Phenotype - inflammation

Entringer S et al. Maternal estriol concentrations in early gestation predict infant telomere length. J Clin Endocrinol Metab. 2015 Jan;100(1):267-73.
Without the protection from telomeres, our cells age and
eventually die and are susceptible to mutations, and turn on inflammation (SASP)
Telomeres
Same Genes, Why the Difference?
Telomeres are the Biological Clock of Aging
• Organs deteriorate as more and more of their cells die off or enter cellular senescence.
• Shortened telomeres impair immune function that might also increase cancer susceptibility
• Telomere length represents biological age as opposed to chronological age
– Eisenberg DT. An evolutionary review of human telomere biology: the thrifty telomere hypothesis and notes on potential adaptive paternal effects. Am J Hum Biol.2011. 2, 149-67
The Impact of Telomere Shortening • "Short telomeres appear to be associated with
increased risks for human bladder, head, neck, lung, and renal cell cancers”
• Fraternal twins with the shortest telomeres had a three times greater risk of death during the follow-up period than their co-twins with the longest telomere measurements

The Telomere Syndromes
• Short telomeres are involved with almost all the diseases associated with aging
• Few specialists are aware of the root cause of the diseases they are treating

Is Telomerase Activation the “Fountain of Youth”?
• TA-65 works in selected biological systems • Multiple mechanisms of aging still continue but • Mechanisms are interconnected • Inflammation – Telomere dysfunction • Telomere loss – senescence – senescence associated secretory
phenotype (SASP) – cytokines - inflammation
• But, people who have transiently activated the telomerase enzyme, have seen statistically significant improvements in their immune system, cardiovascular and metabolic bio-markers, bone density, skin elasticity and Quality of Life

TA 65
Anecdotal reports • Skin • Presbyopia • Energy • Aerobic capacity • Immune function
• Less viral infections • Less basal cell skin cancer
“THE TA 65 FOR MYSELF IS GREAT. I AM NEVER WINDED WHEN I DO SPORTS (HORSE BACK RIDING, SNOW SKIING) I NEVER FEEL THE NEED TO CATCH MY BREATH. IT IS EXPENSIVE, BUT I WILL CONTINUE TO USE IT.”
“ I just pop out of bed. Before, I would kind of think that it would be a minor task and think about the steps are required to launch myself out of bed.”
CHI emailed question: Your observations on TA-65?
• “Several years ago, I started wearing tennis shoes or sandals around the house even after putting on pajamas - because my feet were just a little tender walking around on hardwood floors. Now, without even thinking about it, I realize that I do not bother to wear shoes around the house after putting on pajamas. My feet are not sensitive to hard floors any more.”
“ I am stronger overall. I can see markedly better muscle definition in my arms and shoulders. Tennis players may know what I mean when I say that am now able to project markedly more power on the tennis court. I am quite sensitive to this as I take a couple lessons a week and play a lot of tennis. .” “My overall sense of well being and physical confidence and strength almost seem weird at first as if I am transitioning to a different person. Definitely a little strange. Of course, it is all good.”
CHI emailed question: Your observations on TA-65?
“Thanks for your email concerning TA 65 and one thing I have noticed is that I’m not getting as many sinus infections as I have in the past which is huge. My Lymphedema seems to be improving and that could also be because of the supplements I’m taking along with a healthy diet including more protein.”
“For me, it seems like there is greater sense of energy, AND a sense of dietary control. I have watched my morning fasting glucose fall steadily since taking TA-65. Is it TA-65, finally getting control of exercise and food, the workouts, or the Placebo effect? Who knows? I can only say that at 70 I continue to come in 1st, 2nd or 3rd in my running….and I do not train.. Does it cost too much? Of course?” AB, physician and researcher
“ I believe the TA65 gives me more energy and sometimes I only take one because it is so expensive.” “In the past, my right leg was not as strong as my left in going up the stairs to my porch, especially if I was carrying groceries or whatever and I would have to kind of plan the step. Now I no longer even think about it because the issue has disappeared. “ “I notice it will interfere with my sleep if I take it at night so I take one in the morning and one mid afternoon.. In conclusion I would say it gives me more energy.”
• “I was getting basal cell skin cancers removed every year for the past 5 or 6 years but have not had any found since I started TA-65”
• “People have commented on how good my skin looks”
• “My swimming speed has improved in short triathlons”
• “Memory seems better with no other changes in program other than adding TA-65”
Why use TA-65? • In preventive/regenerative medicine we want to optimize health
and fitness for our patients and ourselves • We want to use multiple modalities: Lifestyle, neutraceuticals,
hormone optimization. • Telomere optimization through TA-65 is a powerful addition of
another approach to health and fitness. • We have adequate data that TA-65 works to increase telomerase
and lengthen telomeres and that it is safe. • We have adequate data that TA-65 improves immune function in
T cells • Telomerase also protects us against inflammation, protects
mitochondria and is necessary for optimal brain function
• We could wait 20 years for a prospective double blind controlled study but….
• We could use the information we have now to prevent the constant erosion of our telomeres, our DNA and our lives.

How are the results reported? The Patient Telomere Score is calculated based on the patient’s average telomere length in peripheral whole blood cells. This average is then compared to telomere lengths from a population sample in the same age range as the patient to determine the patient’s percentile score.

REPEAT DIAGNOSTICS TELOMERE LENGTH
ANALYSIS How are the results reported? (2 Ways) -The 2-Panel assay provides measurements of telomere length for total lymphocyte and granulocyte populations. - The 6-Panel assay, telomere lengths are measured for lymphocytes and granulocytes as well as B-cells, naïve and memory T-cells and NK cells. Sample report info: http://repeatdiagnostics.com/testinfo.html Procedure: Telomere length analysis utilizing multicolor flow-FISH can be performed on subsets of human leukocytes from peripheral blood collected from individuals. Helpful links: http://repeatdiagnostics.com/index.html
How are the results reported? • Mean telomere length
• • Percentage of short telomeres
• Procedure: HT Q-FISH, same as Q-FISH (determination of telomere length on chromosomes from blood samples by hybridization of specific probes using fluorescent microscopy) with high throughput, multiple simultaneous samples. Helpful links: http://www.lifelength.com/index-eng.html
