Research Interest
 
Prostate cancer (PCa) is one of the common malignancies and the second leading cause of tumor-related mortality in American male. The treatment with bicalutamide (casodex), the most widely used androgen receptor (AR) antagonist, is a standard systemic PCa treatment. Unfortunately, after a certain time of bicalutamide treatment, most PCa patients usually evolve to an androgen independent or hormone refractory state and current antiandrogens become ineffective. The precise mechanisms of how AR antagonist function is abrogated in progressive PCa after androgen deprivation are the central importance for the development of new therapies and represent a major clinical challenge in PCa treatment.
Protein and its spatiotemporal distribution change play a central role in all of biological processes including PCa cell transition from androgen dependence into androgen independence. Recently, large-scale protein identifications from highly complex protein mixtures have been achieved with proteomic strategies. Based on the improvement of mass spectrometry (MS) and sample preparation such as peptide fractionation with strong cation exchange (SCX) column in high pressure liquid chromatography (HPLC), now, MS-based proteomics has made it possible to directly identify thousands of proteins expressed in various cell lines. Moreover, isobaric mass tagging techniques such as tandem mass tags (TMT) and isobaric tags for relative and absolute quantitation (iTRAQ) have been well established as effective approaches for analysis of protein expression with accurate and precise relative quantitation of peptides in multiple samples simultaneously. The advantages of high-throughput and high-sensitivity of large-scale proteome analysis facilitate understanding of various mechanisms of cancers including PCa and development of new diagnostic/prognostic biomarkers and therapeutic targets.
 
Some of my interesting projects are shown below:
(1)   Proteomic characterization and comparison of proteins expressed in androgen-dependent LNCaP-C33 and androgen-independent LNCaP-C81 cells.
(2)   Functional proteomics of androgen receptor expressed in androgen-dependent LNCaP-C33 and androgen-independent LNCaP-C81 cells.
(3)   In charge of CCRTD Core Facilities to provide services for all of cancer related researches in CCRTD and chemical/biological community in CAU.
