Current Research: Research efforts in my lab focus on the molecular basis of human disease, specifically within the nervous system.   Currently, we are investigating more natural, safer treatment options for neuroinflammatory diseases such as multiple sclerosis as well as neural-derived cancers.  Using cellular and animal models, we are testing the ability of two classes of molecules—cannabinoids and phytoestrogens—to reduce glial activation characteristic of neuroinflammatory diseases and to induce apoptosis in neural-derived cancer cells.  Students use molecular biology techniques such as tissue culture, ELISAs, and western blots in these studies.

 Dr. Nathan Reyna

  • Assistant Professor

Ph: 870-245-5240

  • B.S. College of the Ozarks, General Biology
  • M.S. University of Arkansas, Plant Breeding and Genetics
  • Ph.D. University of Arkansas, Cell and Molecular Biology

Current Research: My main research interests are in plant signal transduction in relation to biotic and abiotic stress.  I am interested in how plants perceive an external signal at the molecular and cellular levels and subsequently transduce that signal throughout the plant.  Research in my lab will work to characterize both a plant’s physiologic responses as well as its changes in gene expression in response to plant disease and environmental stresses.  In the past my plant model has been rice (Oryza sativa) however; at OBU I use Arabidopsis and tobacco. Mutants of both plant species can easily be obtained and analyzed over a relatively short time period.  These characteristics make both Arabidopsis and tobacco ideal to use in an array of classes from physiology to cell and molecular biology, as well as in student oriented research projects.

Ph: 870-245-5107

  • B.A. Arkansas Tech University, 1981, Psychology
  • Ph.D. Memphis State University, 1985, Experimental Psychology and Biopsychology

Research Interests: History of Neuroscience and a focus on molecular neuroscience examining ajulemic acid (a synthetic cannabinoid) and resveratrol (a phytoestrogen) as potential treatments of neurodegenerative disease. Using microglia, astrocytes, and neuroblastoma as cellular models of multiple sclerosis, the research centers on identifying the modulating effects of ajulemic acid and resveratrol in neuroinflammation, the receptors through which these modulation effects occur, and a role for ajulemic acid and resveratrol in neuroprotection. Another emerging research line is the influence of the perception of ovulation on estimates of time.
