Background

Chan-Hyun Na, Ph.D., has extensive experience in mass spectrometry-based proteomics, imaging mass spectrometry, bioinformatics, and computer programming. Also, he has been trained in molecular biology and neurodegenerative disorders. He obtained his Ph.D. from POSTECH, South Korea, and then he moved to Konkuk University, South Korea, where he established and optimized imaging mass spectrometry for biomarker discovery from renal cell carcinoma tissues. Subsequently, he joined Emory University, where he developed various proteomics methods using Fourier Transform-based mass spectrometry to study ubiquitin biology. After joining Johns Hopkins University, he has been involved in applying proteomics technologies for discovering biomarkers and disease mechanisms of various neurodegenerative diseases, elucidating novel protein-protein interactions in a variety of contexts, identifying cryptic open reading frames encoded in the human genome, and identifying long-lived synaptic proteins by measuring turnover of synaptosome proteins. In addition, he served as research director of the Center for Proteomics Discovery, Johns Hopkins University School of Medicine, completing over 120 proteomics projects successfully.

Research Summary

His laboratory has primarily focused on developing novel proteomics technologies and applying mass spectrometry-based proteomics/metabolomics technologies to various biomedical studies. The representative proteomics technology we developed is an in-situ cell-type-specific proteomics method using antibody-mediated biotinylation (iCAB), with which cell-type-specific proteome analysis can be achieved for any tissues with specific marker proteins without the need for genetic modification or an expensive instrument. The application to biomedical studies includes discovering noncanonical aberrant proteins involved in various diseases, pathogenesis pathways, and biomarkers. For the discovery of noncanonical aberrant proteins involved in various diseases, he is incorporating genomics or transcriptomics data with proteomics data to discover proteins that are not annotated in reference protein databases. For the discovery of pathways involved in various diseases, he identifies differentially regulated proteins, post-translational modifications, interacting proteins, and metabolites/lipids in biological samples occurring during the pathogenesis process in collaboration with various laboratories at Johns Hopkins. For the biomarker discoveries, he identifies candidate biomarkers in human biological fluids, such as human cerebrospinal fluid and serum, using discovery proteomics approaches and validates them using targeted proteomics approaches.
