Human pheromones: epigenetic effects
Evidence of biological process that embeds social experience in DNA that affects entire networks of genes
October 11th, 2012 in Genetics
Excerpt:” This study provides strong evidence of a biological process that embeds social experience in DNA in the brain that affects not just a few genes but entire networks of genes,” says Szyf. “We highlighted the immense importance of the social environment during childhood and illustrated the profound consequences of child adversity on the way our DNA is programmed. Because of our new findings, we now have a broader understanding of how to prevent and treat mental and physical health challenges”.
Link to open access article: Conserved epigenetic sensitivity to early life experience in the rat and human hippocampus.
Article excerpt: “In both rats and humans, we identified a broad but selective response to early life experience that is enriched in suspected regulatory regions, exhibits evidence of a long-range coordination between distant sites, and seems to particularly target the regulation of the protocadherin families of genes, suggesting that these genes may also be involved in the response to early life experience.”
My comment: The cause and effect relationship not mentioned is the epigenetic effects of nutrient chemicals and pheromones that I detailed. On10/11/12 I presented the evidence that this cause and effect relationship is common to species from microbes to man using the honeybee model organism as an example (at the Society for Social Neuroscience annual meeting in New Orleans.
