Rap1a Activity Elevated The Impact Of Endogenous Ages In Diabetic Collagen To Stimulate Increased Myofibroblast Transition And Oxidative Stress, Stephanie D. Burr, Christopher C. Dorroh, James A. Stewart

Faculty and Student Publications

Diabetics have an increased risk for heart failure due to cardiac fibroblast functional changes occurring as a result of AGE/RAGE signaling. Advanced glycation end products (AGEs) levels are higher in diabetics and stimulate elevated RAGE (receptor for AGE) signaling. AGE/RAGE signaling can alter the expression of proteins linked to extracellular matrix (ECM) remodeling and oxidative stressors. Our lab has identified a small GTPase, Rap1a, that may overlap the AGE/RAGE signaling pathway. We sought to determine the role Rap1a plays in mediating AGE/RAGE changes and to assess the impact of isolated collagen on further altering these changes. Primary cardiac fibroblasts from …

Selective Inhibition Of Plasmodium Falciparum Atpase 6 By Artemisinins And Identification Of New Classes Of Inhibitors After Expression In Yeast, Catherine M. Moore, Jigang Wang, Qingsong Lin, Pedro Ferreira

Faculty and Student Publications

Treatment failures with artemisinin combination therapies (ACTs) threaten global efforts to eradicate malaria. They highlight the importance of identifying drug targets and new inhibitors and of studying how existing antimalarial classes work. Here, we report the successful development of a heterologous expression-based compoundscreening tool. The validated drug target Plasmodium falciparum ATPase 6 (PfATP6) and a mammalian orthologue (sarco/endoplasmic reticulum calcium ATPase 1a [SERCA1a]) were functionally expressed in Saccharomyces cerevisiae, providing a robust, sensitive, and specific screening tool. Whole-cell and in vitro assays consistently demonstrated inhibition and labeling of PfATP6 by artemisinins. Mutations in PfATP6 resulted in fitness costs that were …

Synthesis, Characterization, And Evaluation Of Amphiphilic Cell-Penetrating Peptides As Sirna Delivery Tools For Cancer Therapy, Muhammad Imran Sajid

Pharmaceutical Sciences (PhD) Dissertations

Post-transcriptional gene silencing (PTGS), also termed as RNA interference (RNAi) possess a great therapeutic potential. Three siRNA-based products have been recently approved that have developed a renewed interest in the scientific community to explore this alternative therapeutic area rigorously. However, several challenges are limiting their use as a widespread therapeutic agent. The limitations include their membrane impermeability, short half-life, elimination by the kidney, entrapment by the reticuloendothelial system, sequestration by plasma proteins, endosomal trap, and off-target effects.

Several delivery systems and transfection agents have been investigated to address these challenges. Still, most of the systems suffer from toxicity and low …

Cytotoxic Activity Of Non-Specific Lipid Transfer Protein (Nsltp1) And Proteomic Evaluation Of Heparin-Binding Proteins From Ajwain (Trachyspermum Ammi) Seeds, Saud Alshammari

Pharmaceutical Sciences (PhD) Dissertations

Trachyspermum ammi, commonly known as ajwain, is a member of the Apiaceae family. It is a therapeutic herbal spice with diverse pharmacological properties, used in traditional medicine for various ailments. However, all previous studies were conducted using small molecule extracts, leaving the protein’s bioactivity undiscovered. The present study demonstrated the antiproliferative activity of ajwain nsLTP1 in MCF-7, AsPC-1, and MCF10A cell lines and its structural stability in human serum and high-temperature conditions. The antiproliferative activity of ajwain nsLTP1 was evaluated in MCF-7 and AsPC-1 cell lines using an MTT assay. Annexin V-FITC and PI staining were used to detect the …

Discovery Of Ojt010 As A Novel Inhibitor Of Severe Acute Respiratory Syndrome Coronavirus 2, Manvir Kaur

Dissertations (2016-Present)

The current pandemic of coronavirus disease (COVID-19) caused by the highly infectious pathogen, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), represents a global public health challenge. The emergence of deadly SARS-CoV-2 variants with mutations on the viral genes has made it more imperative to discover therapeutics that target the host receptors for COVID-19 treatment. Therefore, our research has targeted the critical host entry receptors: Angiotensin-converting enzyme-2 (ACE2) for SARS-CoV-2 entry into the human cells. SARS-CoV-2 is an enveloped RNA beta coronavirus that infects human cells via interaction with the ACE2 receptor, followed by viral replication and virus dissemination. Spike protein …

Content And Activity Of Cytochrome P450 3a In Rat Brain Microsomes And Mitochondria, Nouf Alshammari

Pharmaceutical Sciences (MS) Theses

The potential contribution of CYP3A in brain microsomes and mitochondria is crucial to designing appropriate therapeutic strategies and preventing toxicities. Until recently, there has been limited data reported in the literature with respect to CYP3A activity and its expression in the brain tissue. The reason for this limitation is most likely the relatively low level of CYP3A in the brain tissue. To this end, the primary purpose of this study is to develop a CYP3A functional assay in rat brain mitochondria and microsomes to determine the Michaelis-Menten kinetics of the formation of CYP3A-mediated hydroxylated metabolites of midazolam by UPLC-MS/MS. We …

Generation Of A More Immunogenic Fh Vlp Platform To Support Covid-19 Vaccine Development, Jewel E. Voyer, Xinyuan Chen Phd.

Senior Honors Projects

The SARS-CoV-2 based pandemic has seen almost a million deaths in just the United States according to the CDC. This number is due to the increase of variants of COVID-19, therefore calling a demand in vaccine production. Vaccine adjuvants and carriers have been studied to increase the immunogenicity and safety of a variety of immunizations. Flagellin fused Hepatitis B core (FH) virus like particles (VLP) has been studied to have beneficial effects of TLR5, IL6 levels, and lack of body temperature rise in murine study. The FH platform also provides an improvement from its predecessors FljB alone which is a …

Investigating Hybrid Cyclic/Linear And Linear Peptides As Vehicles For Nucleic Acid Delivery, Abdulelah Alhazza

Pharmaceutical Sciences (MS) Theses

Small interfering RNA (siRNA) and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR-associated Protein 9 (Cas9) are advanced biotechnological approaches that have been able to temporarily downregulate gene expression through post-transcription RNA interference or permanently knockdown a protein via creating a mismatch in DNA, respectively. Nucleic acids are anionic and hydrophilic molecule, which cannot enter the cell through passive diffusion and/or interaction with the cell membrane. Cell-penetrating peptides (CPPs) offer a unique carrier for nucleic acid delivery, where positively charged components of CPP bind to the negatively charged nucleic acid and the hydrophobic components enhance the interaction with cell membrane, and …
