An Assessment Of Bsa Protein Hydrogel Biocompatibility In The Vertebrate Intestinal Tract, Ryan Joseph Garde
An Assessment Of Bsa Protein Hydrogel Biocompatibility In The Vertebrate Intestinal Tract, Ryan Joseph Garde
Theses and Dissertations
The fields of biomedicine and pharmacology have a mission to design methods to treat disease while minimizing adverse side effects using novel drug delivery systems. In developing new therapeutic systems, it is crucial to test that drug delivery systems target pathological cells and tissue and is non-toxic in healthy tissue. One promising method for targeted drug delivery is the use of hydrogels as carriers. Here, we studied the effects of bovine serum albumin (BSA) hydrogel consumption to assess the potential for hydrogel use in treating intestinal disease via oral administration. We investigated intestinal architecture and cell populations following hydrogel treatments …

The lateral line is a mechanosensory system used by fish to sense the movement of water. It is evolutionarily related to the inner-ear in humans. For both organisms, the binding of the CXCL12 (SDF-1 ligand) to the CXCR4 receptor induces conformational changes needed to activate signal transduction. This signaling results in numerous cellular responses such as cell fate, chemotaxis, and gene transcription. Interestingly, researchers have found that another signaling molecule, CXCL14, can also bind to the CXCR4 receptor with high affinity (Tanegashima et al., 2013). As a result, we hypothesize that CXCL14 modulates CXCL12-mediated chemotaxis, presumably acting as an allosteric …

Structure-activity relationships (SAR) in the aurone pharmacophore identified heterocyclic variants of the (Z)-2-benzylidene-6-hydroxybenzofuran-3(2H)-one scaffold that possessed low nanomolar in vitro potency in cell proliferation assays using various cancer cell lines, in vivo potency in prostate cancer PC-3 xenograft and zebrafish models, selectivity for the colchicine-binding site on tubulin, and absence of appreciable toxicity. Among the leading, biologically active analogs were (Z)-2-((2-((1-ethyl-5-methoxy-1H-indol-3-yl)methylene)-3-oxo-2,3-dihydrobenzofuran-6-yl)oxy)acetonitrile (5a) and (Z)-6-((2,6-dichlorobenzyl)oxy)-2-(pyridin-4-ylmethylene)benzofuran-3(2H)-one (5b) that inhibited in vitro PC-3 prostate cancer cell proliferation with IC50 values below 100 nM. A xenograft study in nude mice using …

Identification Of Proteins Interacting With Zebrafish Miro Orthologs In The Yeast Two-Hybrid System, Yiran Tao
Honors Program Theses
The motility of mitochondria is required for providing energy and maintaining basic cellular functions in neurons. Mitochondrial Rho GTPase (Miro) is an essential component of the mitochondrial trafficking machinery, a protein complex that anchors mitochondria to the microtubule motor protein for long-distance transport. As a protein localizing to the mitochondrial outer membrane, Miro regulates the morphology and the motility of mitochondria. Upon mitochondrial depolarization, the PINK1/Parkin pathway is activated to arrest mitochondrial movement by targeting Miro for phosphorylation and ubiquitination in a calcium-sensitive manner. However, it remains unclear what effects the PINK1-dependent phosphorylation has on the structure and binding properties …
