Quantitative Proteomic Investigation Of Disease Models Of Type 2 Diabetes, Mark Gabriel Athanason
Quantitative Proteomic Investigation Of Disease Models Of Type 2 Diabetes, Mark Gabriel Athanason
USF Tampa Graduate Theses and Dissertations
PANcreatic DERived factor (PANDER, FAM3B) is a member of a superfamily of FAM3 proteins that are uniquely structured and strongly expressed from the endocrine pancreas and co-secreted with insulin. Unique animal models available to our lab have indicated that PANDER can induce a selective hepatic insulin resistant (SHIR) phenotype whereby insulin signaling is blunted yet lipogenesis is increased. The complexity of the biological networks involved with this process warranted the logical approach of employing quantitative mass spectrometry based proteomic analysis using stable isotope labeling of amino acids in cell culture (SILAC) to identify the global proteome differences between the PANDER …
Investigation Of Respiratory Syncytial Virus Structural Determinants And Exploitation Of The Host Ubiquitin System, Jillian Nicole Whelan
Investigation Of Respiratory Syncytial Virus Structural Determinants And Exploitation Of The Host Ubiquitin System, Jillian Nicole Whelan

Respiratory syncytial virus (RSV) is a globally circulating, non-segmented, negative sense (NNS) RNA virus that causes severe lower respiratory infections. This study explored several avenues to ultimately expand upon our understanding of RSV pathogenesis at the protein level. Evaluation of RSV intrinsic protein disorder increased the relatively limited description of the RSV structure-function relationship. Global proteomics analysis provided direction for further hypothesis-driven investigation of host pathways altered by RSV infection, specifically the interaction between the RSV NS2 protein and the host ubiquitin system. NS2 primarily acts to antagonize the innate immune system by targeting STAT2 for proteasomal degradation. The goal …
Protein Profiling Of Adenine Nucleoside And Nucleotide Analogs Binding Proteins Using N6-Biotinylated-8-Azidoadenosine Analogs As Affinity Based Protein Profiling Probes, Shikha Mahajan
USF Tampa Graduate Theses and Dissertations
Identification of differential expressions of proteins in proteomic profiles of biological samples shows great potential as a valuable technique for the early diagnosis of various diseases. An important challenge in modern protein profiling approaches is to reduce the complexity of the samples by limiting the number of proteins that need to be evaluated for distinction in the expression between normal and deceased cells. In this research, an affinity based approach for the enrichment of nucleotide and nucleoside binding proteins from a complex cell proteome has been developed. To achieve this goal, new N6-biotinylated-8-azido-adenosine probes (AdoRs) have been designed and synthesized …
