Epigenetic effects underlie sexual preferences IV

Article excerpt: “All of the steps in Figure 2 could also be influenced by sex-specific regulation of miRNA [microRNA] levels that are known to influence sexually dimorphism of mRNA [messenger RNA] concentrations in the brains of mice, and to be influenced by epigenetic control that is heritable across at least one generation (Morgan and Bale 2011).”  (Rice, Friberg, & Gavrilets, 2012, p. 349)

My comment: The difference between my model and the one offered by Rice et al., is that I include more information about the molecular mechanisms responsible for “…sex-specific regulation of miRNA levels that are known to influence sexually dimorphism of mRNA concentrations in the brains of mice” and in other species from microbes to man.

Main conclusion: (Kohl, 2012Human pheromones: epigenetic effects of odors and their affects on behavior

This model of systems biology (“biological embedding”) represents:

1)Nutrient chemical-dependent and social stress-induced intracellular changes in microRNA and messenger RNA homeostasis

2) Intermolecular changes in DNA

3) Experience-dependent stochastic variations in de novo gene expression for odor receptors

4) The required gene-cell-tissue-organ-organ system pathway that links sensory input directly to gene activation in GnRH neurosecretory cells of the mammalian brain

5) The required reciprocity that links gene expression to behavior that alters gene expression (i.e. from genes to behavior and back)

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.
