profile_image The major objective of the Loeken laboratory is to understand transcription regulation during early mammalian embryogenesis. We are focusing on neural tube development in the mouse, the regulation of the gene encoding the Pax-3 transcription factor, and the role of Pax-3 in formation of the neural tube. We have found that expression of Pax-3 is disturbed during diabetic pregnancy, and that consequently, Pax-3-expressing cells undergo p53-dependent apoptosis. This research will increase our understanding of the signals that activate expression of developmental control genes, how they, in turn, regulate developmental programs, and explain the causes of congenital defects of the neural tube, particularly those caused by maternal diabetes, on a molecular level. A more recent area of investigation is the long term effect of maternal diabetes to program risk for metabolic abnormalities, including type 2 diabetes, in the offspring of diabetic mothers. We employ a mouse model and examine the molecular differences in programming of glucose and insulin sensitivity of tissues that regulate glucose metabolism at various stages of development in the offspring of diabetic mothers. -1.
