Research Summary

My laboratory was the first to describe the use of alternative substrates to glucose by the neonatal primate brain, and to document gluconeogenesis in fetal life. We now work on modulating transcription factor function in the pancreatic beta cell in order to reconstruct the beta cell in other cell types. We have developed a “superpromoter” transcription factor which enhances action in cell types cognate with beta cells.

My major clinical research work focuses on the continuation of the TODAY study, an NIH-funded trial of treatments for type 2 diabetes in children and Adolescents. We have demonstrated that the “fat paradox”, the protective effect of obesity on complications of diabetes, extends to retinopathy in the young. The mechanism of this effect is presently being examined. The patients in this trial are being followed into adulthood so that the natural history of type 2 diabetes in young people can be elucidated. We also will be participating in studies of long-acting growth hormone products in children with growth hormone deficiency.
