Epigenetic alterations due to stress

Acute stress alters control of gene activity  August 15, 2012 in Psychology & Psychiatry

Excerpt: “Previous studies have shown that stressful experiences and psychological trauma in early life are associated with long-term altered DNA methylation. Whether the DNA methylation also changes after acute psychosocial stress, was, however, previously unknown.”

My comment:

Nutritional and social stress act via the same central neuronal system in mammals, as detailed in Kohl, J.V. (2012) Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors. Socioaffective Neuroscience & Psychology, 2: 17338.

Integrating what is currently known about chemical ecology and adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction might help others to better realize that “Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.”

Excerpt 2 (from the article linked above): The work originated within the framework of an interdisciplinary research consortium with the University of Trier, the University of Basel and King’s College London. The German Research Foundation and the Swiss National Science Foundation supported the study.

My comment:

This work originated within the framework of interdisciplinary research by two independent researchers with no financial support who collaborated with academically talented researchers beginning in the early 1990s. By 1996, for example, we had a section on Molecular Epigenetics in our Hormones and Behavior review article: From fertilization to adult sexual behavior.

About James V. Kohl 1307 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
