But because the vinclozolin - induced fertility changes occurred in almost every male rat descended from a treated mother rather than in a small percentage of offspring (as is seen in germ line mutations caused by radiation), Skinner suspects an epigenetic mechanism — a change that doesn't mutate the DNA sequence of an animal, but rather affects how genes are expressed.

One type of epigenetic change is methylation, where a methyl group is added to or removed from a base in the DNA molecule without affecting the original DNA sequence.

Epigenetics is the study of changes to DNA packaging that influence which genes are expressed but don't affect the DNA sequence itself.

The current work shows that changes in the genetic code of a particular gene can control epigenetic marks at different genes, implying that a gene's genetic code can affect whether other genes are turned on and off, which makes it important to understand the function of all genes involved, not just the one with the so - called misspelling.

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).

''... we hypothesize that repeated stress - related allostatic overload may affect brain function at three basic levels: (a) at the cellular level, it may compromise proteostasis (e.g. tau protein), organelles homeostasis, and induce epigenetic changes in neuronal DNA; (b) at the tissue level it may affect intracellular communication (synaptic contacts), number of cells (reduction of neuronal density), composition of the extracellular matrix (accumulation of amyloid plaques), and neuroinflammation; (c) at the systemic levels it may alter the brain's regulation of behavior (cognitive decline).

The focus of the conference was connecting how epigenetics (cellular and physiological phenotypic trait variations that are caused by external or environmental factors that switch genes on and off and affect how cells read genes instead of being caused by changes in the DNA sequence — in other words nutrition and lifestyle choices) impact whether or not an individual actually develops a specific health issue even though they have a SNP mutation.
