Epigenetic effects underlie sexual preferences IV

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.

Human Pheromones and sex differences in brain maturation

December 10, 2011 James V. Kohl 0

The effect of GnRH on secretion on luteinizing hormone/follicle stimulating hormone ratios and steroidogenesis, links social odors to brain maturation across species of mammals, as well as vertebrates. Experience-dependent brain-directed behaviors should be as variable as would be expected by the association between food odors and food preferences.

The Sex Lives of Insects: Part III

August 2, 2011 James V. Kohl 0

The “rules” of the required molecular biology involve ligand-receptor binding. For example, from yeasts to mammals, genetic conservation of the ligand: gonadotropin releasing hormone (GnRH), and the diversification of its receptor (GnRHR) are part of the rules.
