Novel Biomarkers Of Ciliary Extracellular Vesicles Interact With Ciliopathy And Alzheimer’S Associated Proteins, Ashraf M. Mohieldin, Amal Alachkar, John R. Yates Iii, Surya M. Nauli

Pharmacy Faculty Articles and Research

Ciliary extracellular vesicles (ciEVs), released from primary cilia, contain functional proteins that play an important role in cilia structure and functions. We have recently shown that ciEVs and cytosolic extracellular vesicles (cyEVs) have unique and distinct biomarkers. While ciEV biomarkers have shown some interactions with known ciliary proteins, little is known about the interaction of ciEV proteins with proteins involved in ciliopathy and neurodegenerative disorders. Here, we reveal for the first time the protein-protein interaction (PPI) between the top five ciEVs biomarkers with ciliopathy and Alzheimer disease (AD) proteins. These results support the growing evidence of the critical physiological roles …

One of these possible alternative treatment methods is bacteriotoxins including bacteriocins and tailocins. The focus of this study is a bacteriotoxin from Burkholderia cenocepacia (ATCC 25608), which was induced for toxin using a modified UV light induction procedure and tested against a variety of Pseudomonas and Burkholderia for its killing capacity. Various other pathogenic strains were then induced with UV light and tested. The results showed that the toxin from ATCC 25608 was very effective against most of the Burkholderia tested and warrants …

Ionic Liquid-Solvated Chitosan Nanoparticles As A Novel Method Of Treating Atopic Dermatitis, Leslie Bell

Honors Theses

Atopic dermatitis, or eczema, is an inflammatory skin disease resulting in dry, red, and itchy skin that affects almost 20% of the population of the Western world. This disease creates a physical, emotional, as well as financial burden on those affected, as well as their families. Current treatment options are only somewhat effective, and do not have a long duration of release and therefore efficiency. Furthermore, treatment plans involving corticosteroids need to be closely regulated to monitor side effects such as skin thinning. Other options include topical tacrolimus, emollients, and oral antihistamines, each with varied side effects. This project is …

A Review Of Calcineurin Biophysics With Implications For Cardiac Physiology, Ryan B. Williams

Theses and Dissertations

Calmodulin is a prevalent calcium sensing protein found in all cells. Three genes exist for calmodulin and all three of these genes encode for the exact same protein sequence. Recently mutations in the amino acid sequence of calmodulin have been identified in living human patients. Thus far, patients harboring these mutations in the calmodulin sequence have only displayed an altered cardiac related phenotype. Calcineurin is involved in many key physiological processes and its activity is regulated by calcium and calmodulin. In order to assess whether or not calcineurin contributes to calmodulinopathy (a pathological state arising from dysfunctional calmodulin), a comprehensive …

Keratin 1 As A Cell-Surface Receptor In Cancer, Oluseye Ogunnigbagbe, Christopher G. Bunick, Kamaljit Kaur

Pharmacy Faculty Articles and Research

Keratins are fibrous proteins that take part in several important cellular functions, including the formation of intermediate filaments. In addition, keratins serve as epithelial cell markers, which has made their role in cancer progression, diagnosis, and treatment an important focus of research. Keratin 1 (K1) is a type II keratin whose structure is comprised of a coiled-coil central domain flanked by flexible, glycine-rich loops in the N- and C-termini. While the structure of cytoplasmic K1 is established, the structure of cell-surface K1 is not known. Several transformed cells, such as cancerous cells and cells that have undergone oxidative stress, display …

Steviol Represses Glucose Metabolism And Translation Initiation In Pancreatic Cancer Cells, Sonam Kumari, Mohammed Sikander, Shabnam Malik, Manish Tripathi, Bilal B. Hafeez, Murali M. Yallapu, Subhash C. Chauhan, Sheema Khan, Meena Jaggi

School of Medicine Publications

Pancreatic cancer has the worst prognosis and lowest survival rate among all cancers. Pancreatic cancer cells are highly metabolically active and typically reprogrammed for aberrant glucose metabolism; thus they respond poorly to therapeutic modalities. It is highly imperative to understand mechanisms that are responsible for high glucose metabolism and identify natural/synthetic agents that can repress glucose metabolic machinery in pancreatic cancer cells, to improve the therapeutic outcomes/management of pancreatic cancer patients. We have identified a glycoside, steviol that effectively represses glucose consumption in pancreatic cancer cells via the inhibition of the translation initiation machinery of the molecular components. Herein, we …

Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Avian species are highly susceptible to the hepatotoxic mycotoxin aflatoxin B₁ (AFB₁). Domesticated turkeys are exquisitely sensitive, due to a combination of highly-efficient hepatic cytochrome P450 (CYP)-mediated bioactivation, and to dysfunctional alpha-class glutathione S-transferases (GSTAs) which typically detoxify the bioactivated electrophilic metabolite exo-AFB₁-8,9-epoxide (AFBO). Wild turkeys are relatively resistant to AFB₁ in large part due to expression of functional GSTAs. Quail, a related Galliforme, are slightly less sensitive in vivo to AFB₁, but whether this is related to the hepatic metabolic profiles of these two critical enzymes has not been rigorously evaluated. …

Development Of Novel Peptide-Doxorubicin Conjugates For Targeting Triple-Negative Breast Cancer, Azam Saghaeidehkordi

Pharmaceutical Sciences (PhD) Dissertations

Triple-negative breast cancer (TNBC) is the most aggressive and difficult to treat subtype of breast cancer. Chemotherapy is an active treatment option in combination with other treatments; however, the side effects limit the effective therapeutic dose. To selectively target the cancer cells, I have synthesized three peptide-drug conjugates (PDCs) to specifically target the TNBC cells. The first PDC contains peptide 18-4 with an additional cysteine in the N-terminal (NH2- CWxEAAYQrFL-CONH2) linked to aldoxorubicin (Aldox), a modified version of a common chemotherapy drug doxorubicin (Dox). The cytotoxicity of the PDC and free Dox (positive control) were assessed against MDA-MB-231, MDA-MB-468, and …

Novel Peptide Biomaterials For Enhanced Delivery Of Sirna Cargo For Treatment Of Ovarian Cancer, Timothy Samec

All Dissertations

Ovarian cancer is the 7^th leading cause of cancer related death and the 5^th most commonly diagnosed cancer among women. Primarily diagnosed in stage III or stage IV, aggressive treatment is necessary and involves surgical debulking and administration of systemic chemotherapeutics. Unfortunately, these strategies fall short in effectively treating ovarian cancer and many patients experience local disease recurrence, development of multidrug resistant tumors, regional or distant metastatic events, or a combination of the three. As such, there is a significant need for additional treatment options and methods of delivery to improve therapeutic efficacy and disease survivability.

Computational Design Of Β-Fluorinated Morphine Derivatives For Ph-Specific Binding, Makena Augenstein, Nayiri Alexander, Matthew Gartner

Student Scholar Symposium Abstracts and Posters

Molecular extension and dissection techniques are used to design a morphine derivative that promotes selective binding in inflamed tissue due to its lower pH while avoiding dangerous activation in the brain. Morphine is used to treat pain associated with inflammation. While being effective analgesics, opioids carry the risk of central side effects, including addiction, respiratory depression, and sedation. Opioids are agonists that bind to the μ-opioid peptide receptor (MOR) within central and peripheral nerves and act via a G-protein coupled receptor pathway.

Deprotonation of the tertiary amine induces a negative charge on the nitrogen, discouraging binding at physiological pH (pH=7.4). …
