Abstract
The US FDA currently encourages the addition of vitamin D to milk and cereals, with the aim of reducing rickets in children and osteoporosis in adults. However, vitamin D not only regulates the expression of genes associated with calcium homeostasis, but also genes associated with cancers, autoimmune disease, and infection. It does this by controlling the activation of the vitamin D receptor (VDR), a type 1 nuclear receptor and DNA transcription factor. Molecular biology is rapidly coming to an understanding of the multiplicity of roles played by the VDR, but clinical medicine is having difficulty keeping up with the pace of change. For example, the FDA recently proposed a rule change that will encourage high levels of vitamin D to be added to even more foods, so that the manufacturers can claim those foods reduce the risk of osteoporosis
. The FDA docket does not review one single paper detailing the transcriptional activity of vitamin D, even though, on average, one new paper a day is being published on that topic. Nor do they review whether widespread supplementation with vitamin D, an immunomodulatory secosteroid, might predispose the population to immune dysfunction. This BioEssay explores how lifelong supplementation of the food chain with vitamin D might well be contributing to the current epidemics of obesity and chronic disease.

Prof. Marshall is currently a Director of the Autoimmunity Research Foundation, an Adjunct Professor of the School of Biological Sciences and Biotechnology, Murdoch University (Western Australia), and a past Chair of the Engineering in Medicine and Biology Society of the Ventura IEEE. He is the Patron of the Australian Autoimmunity Foundation.
Based in the heart of Southern California's "Digital Coast", Dr. Marshall is involved in technologies ranging from Immunology, Biomedicine, Autoimmunity, WiFi Security and Internet Infrastructure through RF, Hardware, Software, Audio/Video and Prepress. Previous speaking engagements have included COMDEX, Microprocessor Forums, WLAN/WiFi conferences, and International presentations in a variety of Medical Specialties.
Pasteur once said "In science, chance favors the prepared mind," and Dr. Marshall's career has certainly taken advantage of the many twisty passages in the fields of both Medical Science and Engineering. The best way to find out what he is doing right now is to look at the list of current presentations (above) or browse his recently published scientific papers.
