Protein Biomarker Discovery of Human Disease

Proteomics requires three components: Biology, Mass Spectrometry, and Bioinformatics. To be successful in this field, efforts have to be devoted to all three areas and novel biomedical factors must be found.

In a disease state, not only is protein expression changed, but changes also occur in the post-translational modification of these proteins. These changes are equally of interest and are concurrently investigated. Specifically, identifying the phosphorylation, glycosylation, ubiquitination, and sumoylation of proteins are among current interests of Dr. Hwang and his group. They believe that this knowledge will help to elucidate the signaling pathways inherent to disease states. Furthermore, they are trying to understand clinical questions within the aspect of systems biology to elucidate the molecular phenomena of selected diseases, especially cancer, which may be caused by alterations of the expression level, post-translational modification, subcellular localization, protein-protein interaction, etc.

Since the proteomic data are voluminous, bioinformatics tools must be utilized to identify the molecules of interest. Future plans include the utilization of bioinformatics tools to enable identification of specific molecules of interest. This aspect is essential due to the complexity and volume of data generated using proteomic strategies. One objective of critical necessity is to establish a database management system (DBMS), which can store the experimental data and identify the target molecules systematically.
