  • Dr. Tipple is the CHF Reba McEntire Endowed Chair in Neonatology and Chief of the Section of Neonatal-Perinatal Medicine. His research uses animal models and cellular approaches to define the molecular mechanisms by which redox-mediated events influence lung injury and repair. An avid mentor and educator, his program actively supports the development of clinician and non-clinician trainees.

Research Interests:

  • As a neonatologist and physician-scientist, my long-term research goal is to develop novel approaches to predict or prevent the development of bronchopulmonary dysplasia (BPD) in premature infants. I have studied the role of the thioredoxin (Trx) system in lung injury for nearly 20 years and have expertise in redox signaling and in murine models of oxidant lung injury. Our primary focus has been the investigation of the mechanisms by which disruption of the selenoprotein thioredoxin reductase-1 (TXNRD1) elicits pulmonary protection. We identified that the TXNRD1 disruption attenuates hyperoxia-induced deficits in lung development in neonatal and adult mice via activation of Nrf2-regulated endogenous antioxidant responses. Nrf2-mediated responses are differentially modified by sufficiency of the trace mineral selenium (Se). Given the presence of Se deficiency in preterm infants and in critically ill patients, the impact of Se and selenoprotein synthesis on lung development and responses to TXNRD1 inhibitors are currently the primary focus of our group.
