Quantitative Analysis Of Endocytosis Of Macrophage Growth Factor Receptor By Molecular Imaging, Victor Georgiev, Emily Toering, Christopher Callahan
Quantitative Analysis Of Endocytosis Of Macrophage Growth Factor Receptor By Molecular Imaging, Victor Georgiev, Emily Toering, Christopher Callahan
The Journal of Undergraduate Research
Endocytosis is a critical cellular process responsible for nutrient uptake, sampling the environment, and cellular signaling. Endocytosis of growth factor receptors is an important step in the regulation of receptor signaling functions. The macrophage growth factor receptor controls growth and differentiation of macrophages, however, the pathway by which the receptor is internalized is not well understood. The analysis showed that for the first time, knockout of endophilin A2 decreases the internalization of macrophage growth factor receptor in primary bone marrow macrophages. This shows that fast endophilin-mediated endocytosis plays a role in the control of the amount of growth factor receptors …
Design, Synthesis And Biological Screening Of Novel Cucsinspired Estrone Analogues Towards Treatment Of Hepatocellular Carcinoma, Mater Hussen Mahnashi
Design, Synthesis And Biological Screening Of Novel Cucsinspired Estrone Analogues Towards Treatment Of Hepatocellular Carcinoma, Mater Hussen Mahnashi
Electronic Theses and Dissertations
Cucurbitacins (CUCS) are natural products with highly oxygenated tetracyclic triterpenes produced mostly by Cucurbitaceae family plant. They are known for their therapeutic efficiency with different biological activities, such as anti-inflammatory, hepatoprotective and anti-cancer. Hepatocellular carcinoma (HCC) is the third leading cause of death worldwide. Previous reports have shown the ability of CUCS to inhibit the growth of hepatocellular carcinoma cell lines (HepG-2) significantly. Structural activity relationship studies suggested the potential of the 23, 24 enone side chain of CUCS to bind to the Epidermal Growth Factor Receptor (EGFR). Due to the limited quantities of CUCS upon isolation and the challenges …
Cbl And Cbl-B Dictate Csf-1r Endocytic Traffic And Signaling In Macrophages, Lu Huang
Cbl And Cbl-B Dictate Csf-1r Endocytic Traffic And Signaling In Macrophages, Lu Huang
Electronic Theses and Dissertations
Macrophage colony stimulating factor receptor (CSF-1R or MCSFR) is a receptor tyrosine kinase essential for the growth and function of macrophages. Understanding the mechanisms that regulate CSF-1R activation and deactivation will provide insights to clinical treatment of macrophage related diseases including chronic inflammation and cancer. Previously, our laboratory showed that CSF-1R undergoes a novel membrane trafficking route that involves macropinocytosis to deactivate CSF-1R signaling. This thesis makes the discovery that the ubiquitin ligases Cbl and Cbl-b cooperate to regulate CSF-1R endocytosis and traffic to macropinosome in macrophages. Macrophages were derived from mice knocked out for Cbl, Cbl-b or the double …
Pretreatment, Enzymatic Hydrolysis, And Fermentation To Ethanol Using A Lignocellulosic Feedstock And Subsequent Recovery Of A Value Added Co-Product: Pure Crystalline Cellulose, Ryan J. Bouza
Electronic Theses and Dissertations
As more demand for alternatives to petroleum and the industrial world’s love of cars increase, cellulosic ethanol will become more important. The ethanol can, of course, be used in the transportation fuel sector, but there is also a potential for co-products to be developed out of the cellulose to ethanol process. Some of these co-products have the potential to replace current petrol products. These co-products may provide the extra revenue generation needed for further investment and development of this industry. This would not only provide better energy independence, but in the United States, it would better satisfy the cellulosic ethanol …
Regulation Of Arf16-2 By Microrna160 During Soybean Root Nodule Development, Spencer Schreier
Regulation Of Arf16-2 By Microrna160 During Soybean Root Nodule Development, Spencer Schreier
Electronic Theses and Dissertations
Soybean is an excellent candidate for sustainable agriculture due to its production of nutritious, versatile beans and the ability to form symbiotic organs called root nodules that perform nitrogen fixation. As demand for both yield and sustainable agriculture continue to increase, root nodules offer an attractive alternative to expensive and environmentally harmful nitrogen fertilizers. Understanding root nodule formation may open genetic engineering avenues for optimizing nitrogen fixation performance and transferring the nodule-formation ability to other plants. A major determinant of nodule numbers and quality in soybean is microRNA 160 (miR160), which dictates developmental stage-specific auxin sensitivity by targeting repressor auxin …

Dissecting The Histone-Binding Mechanism Of A Phd Finger Subtype, Daniel Boamah
Electronic Theses and Dissertations
Disordered tails of histones are critical information retrieval hub and thus, aberrations in the flow of information through these hubs are associated with a number of pathological consequences in human. Mechanism for retrieval of information from these hubs is achieved by protein-protein interaction, i.e. proteins dock onto histone tails to initiate chromatin signaling. Eukaryotes have a number of small peptide binding domains that have evolved to specifically interact with histone tails, and these domains called histone readers as they read the information encoded on histone tails. Plant homeodomain (hereafter PHD) finger, a binucleated zinc finger, family is one such histone …
The Synthetic Biology Of N2-Fixing Cyanobacteria For Photosynthetic Terpenoid Production, Charles T. Halfmann
The Synthetic Biology Of N2-Fixing Cyanobacteria For Photosynthetic Terpenoid Production, Charles T. Halfmann
Electronic Theses and Dissertations
In the last few decades, concerns over global climate change, energy security, and environmental pollution have been rising. To overcome these challenges, the concept of “-nth generation” biofuels has emerged as a strategy to convert solar radiation into fuels and bulk industrial chemicals for societal use, while decreasing our consumption of nonrenewable energy sources. Nitrogen-fixing cyanobacteria hold a distinct advantage in biofuel production over plants, given their ability to convert sunlight, air (CO2 and N2), and mineralized water to energy-dense carbon molecules, as well as fix atmospheric nitrogen gas into ammonia for metabolism. Engineered cyanobacteria with …
