FLATOW: There's another study out this week
showing epigenetic differences between induced stem cells and embryonic stem cells, that induced stem cells had a memory, basically.
But the new data
showing that a large fraction of
epigenetic signatures of ethnicity reflect something other than ancestry suggests that abandoning the idea of race and ethnicity altogether could sacrifice a lot of valuable information about the drivers of
differences in health and disease between different communities.
But in recent years, researchers have
shown that
differences not related to DNA sequence can also be passed down, a phenomenon called
epigenetic inheritance.
Health improvement (allowing to post - pone / escape the diseases and thus live, healthier / disease - free longer, but not above human MLSP of around 122 years; thus these therapies do not affect
epigenetic aging whatsoever, they are degenerative aging problems not regular healthy aging problem (except OncoSENS - only when you Already Have Cancer - which cancer increases
epigenetic aging, but cancer removal thus does not change anything / makes no
difference about what happens in the other cells / about what happens in the normal
epigenetic «aging» course in Normal non-cancerous healthy cells) Although there is not such thing as «healthy aging» all aging in «unhealthy» (as seen from elders who are «healthy enough» who
show much damage), it's just «tolerable / liveable» enough (in terms of damage accumulating) that it does not affect their quality of life (enough yet), that is «healthy aging»: ApoptoSENS - Clearing Senescent Cells (this will have great impact to reduce diseases, the largest one, since it's all inflammation fueled by the inflammation secretory phenotype (SASP) of these senescent cells) AmyloSENS - Dissolving the Plaques (this will allow humans to evade Alzheimer's, Parkinsons and general brain degenerescence, allowing quite a boost; making people much more easily reach the big 100 - since the brain is causal to how long we live; keeping brain amyloid - free and keeping our memories / neuron sharp / means longer LongTerm Potentiation - means longer brain function means longer heavy brain mass (gray matter / white matter retention seen in «sharp - witted» Centenarians who
show are younger brain for their age), and both are correlated to MLSP).
Our results
show that trangenerational
epigenetic effects play a role in adaptive evolution, and suggest that the relationship between changes in methylation patterns and
differences in evolutionary outcomes, at least for quantitative traits such as cell division rates, is complex.
