Our laboratory is developing new diagnostic and therapeutic tools to prevent type 2 diabetes. The prevalence of diabetes has skyrocketed since the 1980s, and attempts to curb this trend have had little impact. One reason is that the tests commonly used to screen for diabetes risk, namely fasting glucose, hemoglobin A1c, and the clinical criteria for metabolic syndrome do not detect the earliest abnormalities. By the time an individual develops impaired glucose tolerance, 50-70% of pancreatic beta-cell insulin secretory capacity has been lost. Thus, it is imperative to identify at-risk individuals earlier, to preserve pancreatic beta cells and effectively prevent both diabetes and prediabetes. We have discovered two novel biomarkers for early metabolic syndrome. One biomarker is based on compact NMR technology, and the second, on dynamic light scattering (DLS). Both are sufficiently practical and inexpensive for translation into the clinic and population settings. The NMR- and DLS-based biomarkers monitor the physical properties of molecules or particles in the blood, in contrast with conventional biomarkers that measure concentrations. Current efforts in the lab are focused on two areas: (1) biomarker discovery and validation using large-scale, longitudinal human population studies, and (2) testing new therapeutic strategies to reverse early insulin resistance, metabolic syndrome and prediabetes.

My research focus is to demonstrate the impact of inflammatory mediators on the pathogenesis of diabetic complications: neuropathy, nephropathy and gastroparesis. We have established that replication defective herpes simplex virus-mediated gene transfer of growth factors (NGF, NT-3, VEGF) can prevent diabetic and drug-induced peripheral sensory neuropathy in animals, and that gene transfer mediated release of inhibitory neurotransmitters (Enkephalin, GABA) in diabetic animals reduces pain concomitantly with a reduction in sodium channel NaV1.7 levels in dorsal root ganglion (DRG). Our recent studies show therapeutic benefits of HSV mediated release of anti-inflammatory mediators (IL-10, sTNFR) in the DRG with a reduction of pro-inflammatory cytokines, subsequently inhibiting painful neuropathy. We have also demonstrated exercise-mediated alleviation of painful neuropathy with a decrease in neuro-inflammation. Currently we are assessing if blocking the release of noxious cytokines improves renal dysfunction and gastric dys-motility in diabetic animals. We are trying to identify novel early biomarkers of inflammation and epigenetic modulators (histone modifications) involved in the progression of neuropathy, nephropathy and gastroparesis in diabetic animals, and are exploring whether inhibiting inflammation or epigenetic changes will alter the progression of these complications. Thus, we are focusing on understanding the role of inflammation and nutritional deficits in the development of diabetic complications and co-morbidities.
