Development and Application of Protected Amino Acids for the Installation of Stable Post-translational Modifications Using Solid-Phase Peptide Synthesis
DownloadFall 2022
This thesis describes the synthesis of non-canonical amino acid building blocks and their use in solid-phase peptide synthesis (SPPS) to explore peptidic drug analogues based on natural products. We replaced sensitive functionalities found in the structure of naturally produced peptides with...

Reports in the literature on the development of new chemical sensing technologies have been growing steadily in number for years. For example, a Web of Science topic search using the term “Chemical Sensing” revealed that over 8 000 papers were published in 2015–2017, with over 40 000 citations to...

Light Responsive Linchpins for Accelerated Discovery of Light-Responsive Mono- and Bicyclic Peptide Ligands
DownloadSpring 2016
In this thesis I describe the development and application of light-responsive (LR) linchpins for efficient discovery of LR-peptides from genetically encoded peptide librar-ies. LR-linchpins have been used for dynamic control of the structure of peptides and their biochemical properties such as...

Systematic microRNAome profiling reveals the roles of microRNAs in milk protein metabolism and quality: Insights on low-quality forage utilization
Download2016
Wang, Diming, Sun, Huizeng, Liu, Jianxin, Guan, Le Luo, Wang, Bing, Liang, Guanxiang
In this study, we investigated the molecular regulatory mechanisms of milk protein production in dairy cows by studying the miRNAomes of five key metabolic tissues involved in protein synthesis and metabolism from dairy cows fed high- and low-quality diets. In total, 340, 338, 337, 330, and 328...

Cyanobacterial RNA Helicase CrhR Localizes to the Thylakoid Membrane Region and Cosediments with Degradosome and Polysome Complexes in Synechocystis sptrain PCC 6803
Download2016
Fahlman, Richard P., Owttrim, George W. , Rosana, Albert R. R., Whitford, Denise S.
The cyanobacterium Synechocystis sp. strain PCC 6803 encodes a single DEAD box RNA helicase, CrhR, whose expression is tightly autoregulated in response to cold stress. Subcellular localization and proteomic analysis results indicate that CrhR localizes to both the cytoplasmic and thylakoid...

Targeting Phosphatidylserine for Positron Emission Tomography Imaging of Cell Death: Annexin V versus Phosphatidylserine-Binding Peptides
DownloadSpring 2016
There is currently no clinically approved, widely used molecular imaging agent for in vivo detection of cell death. Such an agent would be highly useful for early assessment of treatment efficacy in cancer patients, as well as for monitoring many other diseases in which cell death plays an...
