Personal Statement

Chih-Ching Wu obtained his bachelor’s degree in medical technology, master’s degree in microbiology & immunology, and Ph.D. in biochemistry from Chang Gung University, Taiwan. He continued his post-doctoral training in proteomics from 2005 to 2008 and acted as Research Assistant Professor at Molecular Medicine Research Center, Chang Gung University from 2008 to 2010. Dr. Wu has joined Department of Medical Biotechnology and Laboratory Science, Chang Gung University since 2010. In the past decade, his team established multiple assay platforms to systematically identify biomarkers from diseased tissues or body fluids (e.g., sera, saliva, and pleural effusion) that are useful for detection, monitoring, or prognosis of diseases including various types of cancer, schizophrenia, and microbial infections. His research topics also include studies on an interplay between viral infection and host response. His team has been involved in identifying novel host factors that interact with proteins encoded by emerging viruses (e.g., influenza virus and enterovirus A71) and exploring functional roles of these host factors in viral replication.

Lab & Research Interest

My laboratory takes disciplines in medical technology and clinical proteomics. I am interested in discovery of biomarkers for cancer diagnosis, and familiar with proteomics technology, antibody production/characterization, and development of immunoassays. Currently, I am one of the principal investigators involved in Proteomics Core Lab, Chang Gung University. With application of proteomics platforms, I have established the database of secreted proteome of cancer cells and the multiplexed assays to facilitate the identification of cancer biomarkers in body fluid samples. Tumor markers are crucial for cancer detection, diagnosis, prognosis and/or therapeutic monitoring. However, currently available cancer biomarkers have the drawback of lacking specificity and/or sensitivity. Therefore discovery of novel and effective cancer biomarkers is urgently needed. To identify potential cancer markers, we have planned on applying for following systems approaches:

1.   Proteins released by tumor cells (cancer cell secretome) in vitro may reflect the proteins released by tumors in vivo. Thus, analysis of cancer-cell secretomes derived in vitro may represent a feasible strategy for finding potential cancer serum/plasma biomarkers.

2.   Proteins aberrantly expressed in cancer tissues or body fluids (serum, plasma, or pleural effusion) collected from cancer patients may represent as novel biomarker candidates.

3.   The potential markers identified by the approaches 1 and 2 will be further evaluated in the clinical samples from health controls and cancer patients with multiplexed immunoassays or multiple-reaction monitoring mass spectrometry (MRM-MS).

4. The biological and/or pathological roles of the identified marker candidates can be further investigated by using quantitative proteomics, such as iTRAQ (isobaric tags for relative and absolute quantitation) or SILAC (stable isotope labeling by amino acids in cell culture)-based proteomics analyses.
