Characterizing Early-Life Microbiome Functionality In Premature Infant Gut By A Metaproteomics Approach, Weili Xiong
Characterizing Early-Life Microbiome Functionality In Premature Infant Gut By A Metaproteomics Approach, Weili Xiong
Doctoral Dissertations
Microbes inhabit all parts of human body that are exposed to the environment and their interactions with human host mutually benefit each other and play significant roles in human health and diseases. The human gastrointestinal tract harbors the largest population of the microbiota and has gained broad research attention and efforts over the past decade. Colonization of the gut by microbes begins at birth and this early-life bacterial establishment can impact infants’ health and even the human health and lifestyle across an entire life span. Recent studies on community structure and composition of infant gut microbiota have revealed the species …
Development And Integration Of Informatic Tools For Qualitative And Quantitative Characterization Of Proteomic Datasets Generated By Tandem Mass Spectrometry, Rachel Michelle Adams
Development And Integration Of Informatic Tools For Qualitative And Quantitative Characterization Of Proteomic Datasets Generated By Tandem Mass Spectrometry, Rachel Michelle Adams
Doctoral Dissertations
Shotgun proteomic experiments provide qualitative and quantitative analytical information from biological samples ranging in complexity from simple bacterial isolates to higher eukaryotes such as plants and humans and even to communities of microbial organisms. Improvements to instrument performance, sample preparation, and informatic tools are increasing the scope and volume of data that can be analyzed by mass spectrometry (MS). To accommodate for these advances, it is becoming increasingly essential to choose and/or create tools that can not only scale well but also those that make more informed decisions using additional features within the data. Incorporating novel and existing tools into …
Development And Application Of Mass Spectrometry-Based Proteomics To Generate And Navigate The Proteomes Of The Genus Populus, Paul Edward Abraham
Development And Application Of Mass Spectrometry-Based Proteomics To Generate And Navigate The Proteomes Of The Genus Populus, Paul Edward Abraham
Doctoral Dissertations
Historically, there has been tremendous synergy between biology and analytical technology, such that one drives the development of the other. Over the past two decades, their interrelatedness has catalyzed entirely new experimental approaches and unlocked new types of biological questions, as exemplified by the advancements of the field of mass spectrometry (MS)-based proteomics. MS-based proteomics, which provides a more complete measurement of all the proteins in a cell, has revolutionized a variety of scientific fields, ranging from characterizing proteins expressed by a microorganism to tracking cancer-related biomarkers. Though MS technology has advanced significantly, the analysis of complicated proteomes, such as …
Functional Characterization Of Microbial Symbiotic Associations By Metaproteomics, Jacque Caprio Young
Functional Characterization Of Microbial Symbiotic Associations By Metaproteomics, Jacque Caprio Young
Doctoral Dissertations
Rarely are microbes found in isolation in the environment, but rather form symbiotic associations with other microbes or eukaryotic hosts. The advent of the systems biology era has allowed global characterization of these symbiotic associations at levels not previously possible. However, while metagenomic studies have revealed microbial membership and potential genomic information among members taking part in the symbiosis, there is still a significant lag in the functional characterization within these symbiotic associations. Thus, in this dissertation, we utilized a metaproteomic approach to study microbial symbiotic associations. We have developed and applied this robust platform to investigate various symbiotic associations …
