Since coming to Georgia Tech in 2012, the Wu lab has published several important research papers focused on aspects of MS and MS-based proteomics. And recently, the Wu lab was given a critical boost for its groundbreaking research thanks to a CAREER Award from the National Science Foundation.\u003Cbr \/\u003E\u003Cbr \/\u003EWu\u2019s CAREER project, \u201cCharacterizing the Glycoproteome with Effective MS-based Chemical and Enzymatic Methods,\u201d is receiving $625,000 over five years from the NSF. The glyproteome includes all proteins bearing carbohydrates, and glycosylation is one of the most common and essential protein modifications.\u003Cbr \/\u003E\u003Cbr \/\u003E\u201cThis CAREER Award research is mainly about developing new methods to globally analyze glycoproteins in complex biological samples,\u201d says Wu, whose lab is known for its innovative MS-based proteomics techniques, and for applying them to biomedical research. \u003Cbr \/\u003E\u003Cbr \/\u003E\u201cIt is well known that aberrant protein glycosylation is directly related to disease, including cancer and infectious diseases,\u201d he continues. \u201cHowever, a huge gap exists between glycoproteins in complex samples and glycoproteins that can be identified by current methods. There is an urgent need to develop effective methods for the comprehensive identification and quantification of glycoproteins. This research can help us better understand protein function and the molecular mechanisms of disease, which will lead to the discovery of glycoproteins as effective biomarkers and drug targets.\u201d\u003Cbr \/\u003E\u003Cbr \/\u003EIn addition to the award, another research paper from the prolifically published Wu lab has been accepted for publication in Chemical Science.\u0026nbsp; The article entitled \u201cSystematic and site-specific analysis of N-sialoglycosylated proteins on the cell surface by integrating click chemistry and MS-based proteomics,\u201d co-authored by Weixuan Chen and Johanna M. Smeekens and Wu has received some enthusiastic feedback from reviewers, who have noted, \u201cthis is a nice and very solid proteomics study on the metabolic labeling and localisation of sialic acid expression on glycoproteins at the cell surface,\u201d according to Wu.\u003Cbr \/\u003E\u003Cbr \/\u003EFurthermore, Wu adds, \u201cSialic acid modification is a very active topic due to its importance as a cell surface marker and up-regulation in cancer cells, as well as a handle used by pathogens to bind to the host cells in several human viral infections (influenza, adenoviruses). This work is particularly significant because it combines a novel chemoselective tagging approach that is compatible with imaging in live cells, and an enrichment protocol for profiling glycoproteins by mass spectrometry.\u201d\u003Cbr \/\u003E\u2028This is just the latest in a flurry of research papers published by the busy trio \u2013 post-doctoral research fellow Chen, Ph.D. student Smeekens, and Wu. Earlier this year they were published in the journal Analytical Methods as well as Journal of Proteome Research (with co-authors from the Wu lab, graduate student Haopeng Xiao and undergrad George X. Tang). \u003Cbr \/\u003E\u003Cbr \/\u003EAfter being published online in Chemical Science, their latest this paper was highlighted in Chemical \u0026amp; Engineering News, whose editors wrote, \u201cSialic acid-containing glycoproteins are important players in cancer metastasis and viral infections, yet there hasn\u2019t been a method for their complete analysis on cell surfaces. To address that problem, Ronghu Wu and coworkers at Georgia Institute of Technology have developed a method that combines metabolic labeling, chemical modification, and mass spectrometric proteomics.\u201d \u003Cbr \/\u003E\u003Cbr \/\u003EAnd this is just the latest in a flurry of research papers published by the busy trio of post-doctoral research fellow Chen, Ph.D. student Smeekens, and Wu.
