Atomistic Assessment Of Drug-Phospholipid Interactions Consequent To Cancer Treatment: A Study Of Anthracycline Cardiotoxicity, Yara Elsayed Ahmed
Atomistic Assessment Of Drug-Phospholipid Interactions Consequent To Cancer Treatment: A Study Of Anthracycline Cardiotoxicity, Yara Elsayed Ahmed
Theses and Dissertations
Despite being one of the most effective chemotherapeutic agents developed to date, Anthracyclines are notorious for their cardiotoxicity. Their clinical use is frequently limited both in dosage and in prescription due to the severe cardiac damage they cause. The mechanism of anthracycline-induced cardiotoxicity is not yet fully understood. However, it is hypothesized that interactions with the myocardial membrane play an important role in imparting cardiotoxicity. In this study, we use molecular dynamics simulations and density functional theory calculations to study the anthracycline drug molecules and the interactions that they have with the myocardial membrane. We construct a myocardial membrane model …
Development Of Rules Of Attraction For Intercalated Guest Molecules Inside Of A Hydrogen Bonded Framework, Matthew Fischer
Development Of Rules Of Attraction For Intercalated Guest Molecules Inside Of A Hydrogen Bonded Framework, Matthew Fischer
Dissertations
Supramolecular chemistry has synthesized large and small molecules which host guest molecules for several decades. What started as a way to mimic of enzymes in nature, has exploded into a sea of materials such as porous coordination polymers, low-density metal-organic frameworks, inclusion compounds, and hydrogen bonded frameworks. We previously designed a layered framework consisting of a metal complex with coordinate covalent ligands. These ligands have peripheral carboxylic acid groups which hydrogen bond to organic pillars containing terminal amines. The layered structure is separated by these pillars, which are closed-packed, creating 1-dimensional channels able to co-crystallize molecules. There is interest in …
Novel Spectroscopic Tools To Differentiate Drug-Dna Binding Interactions, Fadwa Dhafer Hamad
Novel Spectroscopic Tools To Differentiate Drug-Dna Binding Interactions, Fadwa Dhafer Hamad
Masters Theses
DNA-drug interactions play a major role in therapeutics, diagnostics, forensics and imaging. Drugs bind to DNA in several ways based on the mode of interaction and they alter protein-DNA interactions or breaks/cleaves DNA that can lead to the cure of the disease. The major goal of the research carried out in this thesis is to develop novel optical spectroscopic tools that can differentiate Drug-DNA binding interactions mode whether its intercalation or minor-groove binding. To achieve this goal, we developed two-photon absorption (2PA) cross-section based technique to differentiate between Drug-DNA binding modes. The investigations were carried out on two drug molecules, …
Transcriptional And Antagonistic Responses Of Biocontrol Strain Lysobacter Enzymogenes Oh11 To The Plant Pathogenic Oomycete Pythium Aphanidermatum, Yangyang Zhao, Guoliang Qian, Yuan Chen, Liangcheng Du, Fengquan Liu
Transcriptional And Antagonistic Responses Of Biocontrol Strain Lysobacter Enzymogenes Oh11 To The Plant Pathogenic Oomycete Pythium Aphanidermatum, Yangyang Zhao, Guoliang Qian, Yuan Chen, Liangcheng Du, Fengquan Liu
Chemistry Department: Faculty Publications
Lysobacter enzymogenes is a ubiquitous, beneficial, plant-associated bacterium emerging as a novel biological control agent. It has the potential to become a new source of antimicrobial secondary metabolites such as the Heat-Stable Antifungal Factor (HSAF), which is a broad-spectrum antimycotic with a novel mode of action. However, very little information about how L. enzymogenes detects and responds to fungi or oomycetes has been reported. An in vitro confrontation bioassay between the pathogenic oomycete Pythium aphanidermatum and the biocontrol bacterial strain L. enzymogenes OH11 was used to analyze the transcriptional changes in the bacteria that were induced by the oomycetes. Analysis …

Investigations Into The Role Of Humic Acid In Biomembrane Permeability And The Effects Of Naturally Formed Gold And Silver Nanoparticles On These Interactions, Loice Marklyne Ojwang
Investigations Into The Role Of Humic Acid In Biomembrane Permeability And The Effects Of Naturally Formed Gold And Silver Nanoparticles On These Interactions, Loice Marklyne Ojwang
LSU Doctoral Dissertations
The mechanism and kinetics of the interaction of humic acids (HAs) with a 1-palmitoyl-2-oleoyl-Sn-glycero-3-phosphatidylcholine (POPC) large unilamellar vesicle (LUV) model biomembrane system were studied by fluorescence spectroscopy. All three HAs studied induced a perturbation to the biomembrane bilayer structure at pH 4.8. Concentration dependence studies revealed that biomembrane perturbation increased with increasing HA concentrations for Suwannee River HA (SWHA) from 0 to 20 mg C/L. For both Leonardite HA (LAHA) and Florida Peat HA (FPHA) aggregation influenced biomembrane perturbation at concentrations above 5 and 7.5 mg C/L, respectively. Temperature studies over the environmentally relevant ranges of 10 to 30 °C …
In-Cell And In Vitro Studies Of Disease Related Protein-Protein Interactions Using Nmr-Spectroscopy, Andres Yudiel Maldonado
In-Cell And In Vitro Studies Of Disease Related Protein-Protein Interactions Using Nmr-Spectroscopy, Andres Yudiel Maldonado
Legacy Theses & Dissertations (2009 - 2024)
The receptor for advanced glycation end products (RAGE) is a multiligand cell surface macromolecule that plays a central role in the etiology of diabetes, inflammation, and neurodegeneration. The cytoplasmic domain of RAGE, ctRAGE, is critical for RAGE-dependent signal transduction. As the most membrane proximal event, mDia1 binds to ctRAGE and is essential for RAGE ligand-stimulated phosphorylation of AKT and cell proliferation/migration. We show that ctRAGE contains an unusual alpha-turn that mediates the mDia1-ctRAGE interaction and is required for RAGE dependent signaling. The results establish a novel mechanism through which an extracellular signal initiated by RAGE ligands regulates RAGE signaling in …
