The Behavioral Epigenetics conference, hosted by the New York Academy of Sciences and the University of Massachusetts Boston, is one of the first to examine how epigenetic changes take place, how they alter behavior, and how they can trigger the onset of disorders such as schizophrenia and depression.

The emerging field of epigenetics explores how our lifestyle and environment can change gene expression, for example, by adhering molecules such as methyl groups to the DNA strand.

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).

It may be that, most likely, 5 of the therapies will impact health to nullify many disease but will not change the «aging» process (the one that is disconnected from telomeres but related with epigenetics) and 2 last therapies will be of intrinsic aging, of which one could end up not doing anything but remain a mitochondrial improvement manifesting as removal of mitopathies (such as MELAS) but would not alter the course of aging (such as the seperate epigenetic aging going on).

As the field has changed, though, so too has the scope of the journal, which now encompasses new areas, such as genomics, epigenetics, and computational genetics, while continuing to cover traditional subjects like transcriptional regulation, population genetics, and chromosome biology.

It is well known that our environment and lifestyle factors, such as food choices, smoking and exposure to chemicals, can lead to epigenetic changes.

Aberrant regulation of the epigenetic information results in changes in cell fate decisions, thereby affecting development and tissue homeostasis, and ultimately leading to disease, such as cancer.

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.

In agreement with the hypothesis that such adaptations are due to epigenetic changes occurring during preimplantation, we have detected epigenetic labile genes in the mouse embryo genomes that allow us to study the best IVC method to produce competent and healthy embryos to ensure that assisted reproductive technologies are utilized in the most efficient and safest possible manner.

Recent theorizing within this tradition suggests that these shifts may be manifested in changes in the relative frequency of particular cell types in blood (Irwin and Cole, 2011) as well as in the epigenetic programming and gene expression of such cells (Miller et al., 2011a).

Epigenetics provides another way of understanding how genes and environment interact in that there is increasing evidence that gene expression is moderated by the environment in which the organism grows and develops.15 Genetic information is encoded not just in DNA linear sequences but in epigenetic changes in chromatin structure such as DNA methylation or covalent modifications of the DNA - binding proteins.
