Gerry Boss, MD - Distinguished Professor of Medicine
I have combined primary care internal medicine with basic laboratory research throughout my career. Although to many physicians this may seem a strange combination, the two areas of work complement each other well. Laboratory work is characterized by delayed gratification, sometimes delayed to the point of wanting to give up, whereas primary care can provide an immediate sense of fulfillment, even though of course many frustrations can arise in delivering high quality care. Moreover, basic science research should not be the purview of only subspecialists; there is no reason why primary care physicians should not be able to pursue basic laboratory work. It should also be noted that basic science transcends medical specialties and one does not have to be a cardiologist or nephrologist to study signal transduction pathways in cardiomyocytes or renal tubular epithelial cells.
I have worked in different areas from regulation of carbon flow through the folate pathway to Ras/MAP kinase signaling. I currently have two major research activities. The first is developing the vitamin B12 analog cobinamide as a new therapy for poisoning by multiple toxic chemicals as well as radiation-induced cell damage. Cobinamide has a very high affinity for cyanide and free radicals, and acts as a scavenger of these toxic chemicals. Much of the detrimental effects of radiation are mediated via free radicals. As a vitamin B12 analog, cobinamide is relatively non-toxic, and we have had several pre-Investigators New Drug (IND) meetings with the Food and Drug Administration. We hope to be in clinical trials sometime in 2023.
The second major area of research is studying the regulation of purine nucleotide synthesis by amino acid availability and the phosphatidylinositol 3-kinase/Akt pathway. We have found that amino acids are potent regulators of purine nucleotide synthesis, and that Akt phosphorylates transketolase, a key enzyme in the non-oxidative pentose phosphate pathway that supplies ribose sugars for purine synthesis. As part of these studies, the lab has found that purine synthesis is regulated during the cell cycle. This work could lead to novel forms of cancer treatment, since purines are required for DNA and RNA synthesis and cellular metabolism.
In my laboratory, there are currently two Project Scientists, two post-doctoral fellows, one graduate student, and two research technicians. In addition, I collaborate closely with another physician-scientist faculty member.

Beatrice Golomb, MD - Professor in Residence
Dr. Golomb's laboratory focuses on intertwined themes: 1. The role of free radicals ("oxidative stress"—i.e. the damage that antioxidants protect against), and cell energy impairment in health, illness, aging and disease. 2. Areas of interest encompass Gulf War illness and other chronic multi-symptom illnesses (like Chronic Fatigue syndrome); drugs and exposures that mediate harms from these mechanisms (such as statins, fluoroquinolones, pesticides, trans fats and radiation including non-ionizing radiation); and potentially favorable substances like vitamin D, omega-3s, coenzyme Q10, and chocolate. These mechanisms are also germane to autism, obesity and metabolic syndrome, and neurodegenerative conditions like Lou Gehrig's disease and Parkinson's disease, among other conditions.
A further focus is on research methodology including placebos, “effect modification,” conflict of interest, and risk/benefit balance. It is vital to ensure that risks, as well as benefits, are considered for drugs and exposures, particularly for preventive interventions (Studies are typically designed to optimize benefit detection – and for reasons of human subjects protections and cost efficiency, may relatively obviate detection of harm.). Dr. Golomb was
the first to propose and defend in the peer-reviewed literature the now leading hypothesis for so-called “Havana Syndrome,” that it is due to pulsed radiofrequency radiation
