Investigating The Cytotoxic Effects Of Amino Acid-Based Ionic Liquids And Peg-Pla Nanoparticles On Mcf10a Human Breast Epithelial Cells For Drug Delivery Applications, Ella C. Mertins
Honors Theses
This study investigates the cytotoxic effects of polyethylene glycol-polylactic acid (PEG-PLA) nanoparticles (NPs) both bare and coated with choline-based ionic liquids (ILs) on MCF10A human breast epithelial cells. The goal was to evaluate how IL-modified NPs influence cell viability at varying concentrations and to assess their potential as drug delivery systems. Three choline-based ILs, Choline-L-Asparagine 1:1, Choline-DL-Isoleucinate 1:1, and Choline-L-Leucinate 1:1, were used as surface coatings for PEG-PLA NPs. Additionally, the ILs were tested independently to establish a baseline for their cytotoxicity. Using a luminescent ATP-based viability assay following the treatment of MCF10A cells, the ILs were found to be …
Hyper Stable Variants Of Fgf-1-Fgf-2 Dimer, Madison Shields Mcclanahan
Hyper Stable Variants Of Fgf-1-Fgf-2 Dimer, Madison Shields Mcclanahan
Chemistry & Biochemistry Undergraduate Honors Theses
Fibroblast Growth Factors (FGFs), including FGF-1 and FGF-2, are proteins that play a crucial role in cell proliferation, cell differentiation, cell migration, and tissue repair. FGF-1 and FGF-2 are useful in accelerating the healing process in the human body; however, these proteins are naturally thermally unstable, resulting in a relatively low half-life in vivo. 1,8 In efforts to improve the stability of this protein, FGF-1 and FGF-2 proteins are engineered by combining the amino acid sequences of the two proteins to form a heterodimer and obtain novel properties. These two FGF variants are chosen for their specific wound healing capabilities. …

Developing A Dissociative Nanocontainer For Peptide Drug Delivery, Michael Patrick Kelly
Dissertations, Theses, and Capstone Projects
The potency and specificity of bioactive peptides have propelled these agents to the forefront of pharmacological research. However, delivery of peptides to their molecular target in cells is a major obstacle to their widespread application. A Trojan Horse strategy of packaging a bioactive peptide within a modified protein cage to protect it during transport, and releasing it at the target site, is a promising delivery method. Recent work has demonstrated that the viral capsid of the P22 bacteriophage can be loaded with an arbitrary, genetically-encoded peptide, and externally decorated with a cell-penetrating peptide, such as HIV-Tat, to translocate across in …
Functionalizing Titanium Implants With Bioactive Peptides To Increase Osseointegration, Neil Bernard
Functionalizing Titanium Implants With Bioactive Peptides To Increase Osseointegration, Neil Bernard
Williams Honors College, Honors Research Projects
Orthopedic surgeries have continued to increase, but the material of choice remains constant: titanium. Titanium has become the benchmark implant material due to its durability and non-immunogenic properties. However, while high rates of success are correlated with joint replacement surgery, certain patients with predisposed diseases such as diabetes or arthritis may have increased complications.1 This can be due to lack of osseointegration due to decreased bone formation and mineralization,2 which will lead to increased rates of infection or aseptic loosening of the implant from the bone. 3 Current methods to alleviate these complications include invasive revisional surgeries, which …
