After getting his PhD degree at the University of Maryland School of Medicine (Human Genetics Program) in 1998, Dr. Baek joined the National Institutes of Health as a research fellow where he trained in cancer biology and pharmacology. During his fellowship, Dr. Baek discovered a protein, NAG-1, induced by non-steroidal anti-inflammatory drugs, which are known chemopreventive drugs in colorectal cancer. Dr. Baek joined the faculty of The University of Tennessee in the College of Veterinary Medicine and pioneered defining the critical target genes in chemoprevention. He seeks to understand how anti-cancer compounds act upon these genes to influence cancer prevention or development. Several chemopreventive target genes were identified and characterized in his laboratory, including activating transcription factor (ATF3), early growth response (EGR-1), NSAID activated gene (NAG-1), KLF4, C/EBPβ, ESE-1, and other tumor suppressors. Interestingly, these proteins were also induced by several dietary compounds and PPARg ligands, supporting their role in anti-cancer, anti-obesity, and anti-inflammation activities. His findings have important consequences in the development of new drugs for the prevention of cancer since it may be possible to develop drugs that selectively increase NAG-1 and others in tumors. The findings thus provide a mechanistic explanation for preventing tumor development. Dr. Baek is currently an Associate Professor at The University of Tennessee College of Veterinary Medicine and has published more than 80 manuscripts on the molecular targets of several chemopreventive compounds including phytochemicals, PPARg ligands, and NSAIDs on colorectal tumorigenesis. His research interests include transcriptional regulation of apoptotic genes, chemopreventive study using animal models, and post-translational regulation affected by chemopreventive compounds, with respect to colorectal cancer prevention, anti-obesity, and anti-inflammation.
