New Strategies To Reveal Protein Candidates In Protein-Protein Interactome Study, Meng-Chieh Chen Oct 2014

New Strategies To Reveal Protein Candidates In Protein-Protein Interactome Study, Meng-Chieh Chen

Open Access Theses

Comprehensive protein-protein interaction network analysis can help reveal protein functions in a system-wide manner. A reliable knowledgebase of interaction networks is not only important for selecting the candidates for drug therapies, but also for evaluating the disease risk. In current interaction databases, 322579 interactions comprised of 56460 proteins have been reported (statistical analysis from APID: Agile Protein Interaction DataAnalyzer; http://bioinfow.dep.usal.es/apid/index.htm). The huge datasets are contributed mainly by yeast -two -hybrid (Y2H) screening and affinity-purification followed by mass spectrometry (AP-MS). High false positive rates and failing to cover certain interaction categories are the limitations of these two methods. Here, we developed …

Dissertations, Theses, and Capstone Projects

Eukaryotic initiation factor (eIF) 4F binding to mRNA is the first committed step in cap-dependent protein synthesis. Barley Yellow Dwarf Virus (BYDV) employs a cap-independent mechanism of translation initiation which is mediated by a structural element BTE (BYDV translation element) located in the 3’ UTR of its mRNA. eIF4F bound the BTE and a translational inactive mutant with high affinity; thus questioning the role of eIF4F in translation of BYDV. To examine the effects of eIF4F in BYDV translation initiation, BTE mutants with widely different in vitro translation efficiencies ranging from 5-164% compared to WT were studied. Using fluorescence anisotropy …


Improving The Microbial Source Tracking Toolbox : Evaluating The Use Of Selective Enrichments And Artificial Sweeteners In A Multi-Tiered Approach, Stacey A. Helming Jan 2014

Improving The Microbial Source Tracking Toolbox : Evaluating The Use Of Selective Enrichments And Artificial Sweeteners In A Multi-Tiered Approach, Stacey A. Helming

Legacy Theses & Dissertations (2009 - 2024)

Microbial contamination of surface waters is a public health concern world-wide, with non-point source fecal input contributing to millions of cases of waterborne illness annually. Numerous techniques have been proposed to monitor for non-point source fecal contamination, but few studies have explored the correlation of multiple chemical and microbial fecal source tracking markers in ambient waters. Therefore, the purpose of these studies was to evaluate the use of multiple "ideal" markers of fecal contamination and improve upon any analytical techniques required to identify species-specific fecal contamination in surface waters. The use of selective enrichments to improve the sensitivity of end-point …
