Travis Hughes pursued research in instrument design and then atomic force microscopy of an ion channel while obtaining a B.S. and M.S. degree in Physics from Brigham Young University in Utah (2003). He then moved fully toward biology while obtaining his PhD. in the lab of Leslie Leinwand at the University of Colorado at Boulder in the department of Molecular, Cellular and Developmental Biology where he researched gene therapy of the central nervous system using plasmid DNA as a gene delivery vector (2008). After research in protein redesign at a nascent start-up biotech company in Spain he moved on to NIH (NRSA individual fellowship) supported postdoctoral training in the lab of Douglas Kojetin at the Scripps Research Institute in Jupiter Florida. Training at Scripps synthesized previous experience and education in physics and biology as he used protein and fluorine NMR to reveal an allosteric binding site on a well known type II anti-diabetes drug target (PPARγ). Further funding (NIH pathway to independence award, K99/R00) facilitated training in molecular simulation using AMBER in the lab of Thomas Cheatham III in the medicinal chemistry department at the University of Utah. This funding now supports Dr. Hughes' independent research in connecting drug induced biophysical changes in PPARγ with drug induced functional outputs in cells at the University of Montana, where he started as new faculty in January of 2016. Travis is also associated with the Center for Biomolecular Structure and Dynamics, which provides a rich environment for research in protein dynamics.
B.S. Physics, M.S. Physics, Ph.D. MCD Biology
We study how drugs change the receptors they bind to using various biochemical and biophysical experimental methods along with molecular dynamics simulations. We then connect these drug induced biophysical changes with drug induced functional outcomes in cell culture (e.g. through measurement of drug induced changes in transcription). Our primary methods are multidimensional protein NMR, fluorine NMR, computational methods, isothermal titration calorimetry, time-resolved FRET, fluoresence polarization, cell culture and transcriptome analysis. We focus on the nuclear hormone receptor family, which is the molecular target of more than 10% of FDA approved drugs. Our work improves the biophysical understanding of how drugs produce effects in this family, this knowledge aids development of new therapies with reduced undesired effects. Current work focues on one member of this family, PPARγ, which binds the prescription anti-diabetes drugs pioglitazone (Actos) and rosiglitazone (Avandia).
