Savillo's New Theory[edit]

10/14/2012-- The Impermanence of Epigenes. If Genes could or would not change and be expressed with various factors around it (biotic and abiotic) as an epigene , then the epigene could definitely change by itself too- not necessarily dependent on the gene and its internal environment but also being influenced by the external environment. Therefore to be able to survive successfully there is the polishing of the epigenes for the most capable of existence. Can Natural Selection be an epigenetic factor? From his theoretical biology website..112.205.157.113 (talk) 05:23, 14 October 2012 (UTC)rhyu -- From Savillo's web page- 10/27/2013``Epigenes: How fast (by seconds, years etc.) are the phenotypes (cellular to organismal/cellular) produced/realized by an epigene after the epigenetic interaction with the gene in question took place? A nice topic to dwell with and write about! — Preceding unsigned comment added by 112.202.16.66 (talk) 02:38, 27 October 2013 (UTC)

Additions[edit]

I have added an example of insect/animal epigenetics experiments. Thanks!

Stem Cells[edit]

I have added a section about stem cells, specifically talking about the epigenetic differences between reprogrammed iPSCs and embryonic stem cells. I focus on DNA methylation, since recent research focuses mostly on this type of epigenetic modification in iPSCs. — Preceding unsigned comment added by 149.43.126.65 (talk) 18:19, 2 May 2014 (UTC)

Heritability of traits[edit]

In the definition section, changes in the DNA sequence are excluded. Nonetheless, I seem to remember being taught as a biology student in the 1980's that epigenetic changes in the DNA were by definition heritable changes in the DNA - NOT the normal modifications required for cell differentiation in the lifetime of an organism. Of course the idea was rightly ridiculed by my teachers. The modern notion is a very different use of the term, in fact the two definitions of the term are practically mutually exclusive. I wonder how this confusing situation has come about. It would be useful if an older geneticist who knows better the history of this term can comment and clarify in the article. Much of the misunderstanding of the term may arise from the two very different uses of the word. I cannot imagine that a neuron that differentiates to become a pyramidal cell of a certain kind in a certain part of the brain used in language will have the capacity to confer via epigenetic changes to sperm or egg DNA sequence better linguistic skills to the offspring. Nor can I imagine that any scientist using the term epigenetic today considers something like that to be a possibility. Skamnelis (talk) 14:55, 24 March 2015 (UTC)

Medicine >> Obesity[edit]

Hey all, I was thinking that it would be beneficial if "Obesity" was included as a sub-section of "Medicine." At the very least, we could provide a link to the genetics of obesity Wikipedia article. I'm planning on working on this next week but any help or advice would be much appreciated! --Christyhulett (talk) 06:18, 17 February 2016 (UTC)

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on Epigenetics. Please take a moment to review my edit. You may add {{cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

YesY Archived sources have been checked to be working

Claim about organization needs independent source[edit]

Regarding this revert, [1], I removed this sentence because this claim needs to be supported by a reliable source independent of the organization. I did not find any independent source that even mentions this organization. CatPath (talk) 18:17, 21 May 2016 (UTC)

Agree with User:CatPath (WP:V is quite important to avoid the appearance of being WP:SPAM. But it's also off-topic here, too specific for this higher-level/general article. DMacks (talk) 18:45, 21 May 2016 (UTC)
