Systems biology met epigenetics two decades ago (not two days ago)

Systems biology meets epigenetics: A computational model explains epigenome dynamics during differentiation.” December 4th, 2012.

Excerpt: “Epigenetics and systems biology are two disciplines that created a lot of excitement in the research community in the last decade. It is widely believed that an even bigger potential lies in the combination of both fields, yet experimental and computational scientists have to join forces.”

My comment: In our 1996 Hormones and Behavior review article, we linked molecular epigenetics to systems biology and detailed the links From fertilization to adult sexual behavior. In context, our representation linked the sense of smell to hormonal organization and activation of vertebrate behavior.  The model was subsequently extended to invertebrates and their life history transitions. The epigenetic effects of social stress in mammals were also further detailed.

Yet, here we are, with a computational model at the same time the honeybee model organism exemplifies the epigenetic effects of nutrient chemicals and pheromones across species. Had I not presented (on November 9, 2012) an updated version of the model I’ve used to link the sensory environment to behavior since 1992, it would be less frustrating to see others offering a computational model instead of extending works with model organisms from microbes to man.

You can’t feed sugar to a computational model of epigenetic cause and effect to arrive at an acceptable model for behavior. You can, however, feed glucose to any organism on the planet and quickly see that it is largely responsible for all epigenome dynamics, and that the metabolism of glucose and other nutrient chemicals to species-specific pheromones controls adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction.  Thus, while a computational model may help to explain epigenome dynamics during differentiation of cells and species,  model organisms will continue to explain the epigenetic effects of sensory input on the development of behavior and species survival.

The computational model may, however, help to compute what will happen when an organism runs out of food.

About James V. Kohl 1308 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.
