telomeres,
if indeed they cause disease — is the one that still needs the most research.

telomeres,
if at all, is a level of specificity that the research can't yet provide.
Every time linear chromosomes are replicated during late S phase, the DNA polymerase complex is incapable of replicating all the way to the end of the chromosome;
if it were not for
telomeres, this would quickly result in the loss of vital genetic information, which is needed to sustain a cell's activities.
It is unclear whether shrinking
telomeres will be problematic in culturing human tissue transplants, but
if it turns out they are, Geron has an answer for that too.
The reason, he said, is that
if a TERT promoter mutation arises to push a precancerous lesion — the mole or nevus — toward a melanoma, the chances are greater in someone with short
telomeres that the cell will die before it up - regulates telomerase and immortalizes the cells.
So
if growing up in an urban setting shortens birds»
telomeres, it could lead to a host of other problems down the line, the team argues.
If cells fail to turn up telomerase, they also fail to immortalize, and eventually die from short
telomeres because chromosomes stick together and then shatter when the cell divides.
If we introduced stem cells with nice, long
telomeres in the first place, we could let them wind down and eventually be lost to apoptosis, senescence, or other sources of damage — and just top our tissues up with more stem cells before enough of those cells were lost to begin to impair tissue function.
So we might just be able to deal with cell loss
if we had a sufficiently sophisticated program of stem cell replenishment — using cells engineered to lack the one linchpin function for cancer, namely
telomere elongation.
If it weren't for telomerase, this gradual shortening would eventually lead to the complete loss of the
telomeres in cells that replicate frequently during a life span, and thus the gradual erosion of the genes themselves.
They might do just fine, but
if there's something else going on combined with the shorter
telomeres, that might be enough to kill them.

telomeres or merely whether women who have children start out with shorter
telomeres.»
People carrying the variant might further accelerate the biological aging process
if they smoke, are obese or don't exercise — all of which are bad news for
telomeres.

telomere length.
Parrish and researchers at her company decided it was time to see
if stretching
telomeres in people could also lengthen life.
Christopher Friesen, an author of the study from the University of Sydney, said: «We really don't know
if shortened
telomeres cause disease states or
if they are a by - product of disease and ageing.
If this precious enzyme can stave off
telomere shortening, then can't it also allow us to prevent death — or even reverse the effects of ageing?
If a nascent cancer can't find a way to seize hold of the telomerase - lengthening machinery, their
telomeres will run down, their chromosomes will fray, and the cell will be destroyed before it can kill us.
The isoforms of this histone play complex regulatory roles in several cellular processes — epigenetic regulation of gene expression, selective regulation of developmental genes, and
telomere maintenance — that could contributed to tumor growth and progression
if dysregulated.
«In fact,
if sheep like Dolly and other mammals made by this [cloning] technique are continually shown to be perfectly healthy and not age prematurely, that would just prove that the whole link between the
telomeres and ageing is an unreliable one and not worth worrying about.»
Here are some of the compelling findings on cognitive ability, gut health and immunity,
telomere lengthening, cellular homeostasis and longevity — all processes that,
if optimized, can result in graceful aging.
But
if you do a meditative yoga practice for 12 minutes every day, you make the

So,
if looking youthful and full of energy is your main priority and you want to prevent the
telomeres of shortening too fast and too soon, you know what to do.
If that's not enough to get your attention, another silent and insidious problem is that you may lose bone strength and bone density when cortisol is high, [i] although this is not conclusively proven in women of all ages, [ii] nor is it absolutely clear that run - of - the - mill chronic stress is causal when it comes to bone loss (though it certainly shortens
