Modulation Of Antibacterial Activity And Cytotoxicity In Amphipathic Cyclic Peptide [R4w4] Using Histidine Substitution, Ryan Stueber

Pharmaceutical Sciences (MS) Theses

Antibiotics have been the gold standard frontline defense against bacterial infections for decades. At the same time, these infecting bacteria have continued to evolve to resist developed antibiotics in an almost endless cycle. As such, we aim to take an alternative approach utilizing antimicrobial peptides (AMPs) as a means to end this cycle. [R4W4] is among known AMPs that demonstrated antimicrobial activity against methicillin-resistant staphylococcus aureus (MRSA) with a minimum inhibitory concentration (MIC) of 2.67 μg/mL. This peptide had notably effective antimicrobial activity, especially relative to linear (R4W4). However, it displayed a concerning level of cytotoxicity; eliciting a human embryonic …

Suppression Of Dc-Sign And Gh Reveals Complex, Subset-Specific Mechanisms For Kshv Entry In Primary B Lymphocytes, Nancy Palmerin, Farizeh Aalam, Romina Nabiee, Murali Muniraju, Javier Gordon Ogembo, Jennifer Totonchy

Pharmacy Faculty Articles and Research

Kaposi sarcoma-associated herpesvirus (KSHV) is the causative agent of multiple cancers in immunocompromised patients including two lymphoproliferative disorders associated with KSHV infection of B lymphocytes. Despite many years of research into the pathogenesis of KSHV associated diseases, basic questions related to KSHV molecular virology remain unresolved. One such unresolved question is the cellular receptors and viral glycoproteins needed for KSHV entry into primary B lymphocytes. In this study, we assess the contributions of KSHV glycoprotein H (gH) and the cellular receptor DC-SIGN to KSHV infection in tonsil-derived B lymphocytes. Our results show that (1) neither KSHV-gH nor DC-SIGN are essential …

An Electrophysiological And Pharmacological Study Of The Properties Of Human Ipsc-Derived Neurons For Drug Discovery, Robert F. Halliwell, Hamed Salmanzadeh, Leanne Coyne, William S. Cao

School of Pharmacy Faculty Articles

Human stem cell-derived neurons are increasingly considered powerful models in drug discovery and disease modeling, despite limited characterization of their molecular properties. Here, we have conducted a detailed study of the properties of a commercial human induced Pluripotent Stem Cell (iPSC)-derived neuron line, iCell [GABA] neurons, maintained for up to 3 months in vitro. We confirmed that iCell neurons display neurite outgrowth within 24 h of plating and label for the pan-neuronal marker, βIII tubulin within the first week. Our multi-electrode array (MEA) recordings clearly showed neurons generated spontaneous, spike-like activity within 2 days of plating, which peaked at one …

From Opportunity To Necessity: Development Of An Asynchronous Online Interprofessional Learning Experience, Kristen Mchenry, S. Alicia Williams, Florence M. Weierbach, Kate E. Beatty, Brian Cross

International Journal of Health Sciences Education

Incorporating interprofessional collaboration competencies into both undergraduate pre-licensure and graduate health science students poses challenges for academic health science centers. Certain student groups may have less opportunity to participate in interprofessional learning experiences due to demands of individual programs of study and conflicts in scheduling time with other disciplines. A group of interprofessional higher education faculty members created an innovative online asynchronous interprofessional experience with the primary goals of meeting accreditation standards for specific programs and providing interprofessional education (IPE) to students who were unable to participate in traditional face-to-face IPE experiences already established at the institution. This guide will …

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer that has remained clinically challenging to manage. Here we employ an RNAi-based in vivo functional genomics platform to determine epigenetic vulnerabilities across a panel of patient-derived PDAC models. Through this, we identify protein arginine methyltransferase 1 (PRMT1) as a critical dependency required for PDAC maintenance. Genetic and pharmacological studies validate the role of PRMT1 in maintaining PDAC growth. Mechanistically, using proteomic and transcriptomic analyses, we demonstrate that global inhibition of asymmetric arginine methylation impairs RNA metabolism, which includes RNA splicing, alternative polyadenylation, and transcription termination. This triggers a robust downregulation of multiple …

Epidemiology and Environmental Health Faculty Publications

The factors associated with chronic opioid therapy (COT) in patients with HIV is understudied. Using Medicaid data (2002-2009), this retrospective cohort study examines COT in beneficiaries with HIV who initiated standard combination anti-retroviral therapy (cART). We used generalized estimating equations on logistic regression models with backward selection to identify significant predictors of COT initiation. COT was initiated among 1014 out of 9615 beneficiaries with HIV (male: 10.4%; female: 10.7%). Those with older age, any malignancy, Hepatitis C infection, back pain, arthritis, neuropathy pain, substance use disorder, polypharmacy, (use of) benzodiazepines, gabapentinoids, antidepressants, and prior opioid therapies were positively associated with …

Laser Irradiation As A Novel Alternative To Detach Intact Particulate Matter Collected On Air Filters, Seyed-Mohammadreza Samaee, Rahim Molaei, Robert A. Yokel, Hedieh Pazokian

Pharmaceutical Sciences Faculty Publications

Airborne particulate matter (PM) is collected on specific filters. For subsequent testing, the PM should be detached intact from the filter. Liquid extraction (LE), the standard method to detach PM from air filter surfaces, is challenging and can be tedious. Laser irradiation has been used to characterize PM on filters, but not to detach PM from filters for subsequent testing. A feasibility study was conducted to assess the potential of laser irradiation to detach PM from air filters. Laser-detached PM was deposited on a pre-weighed glass plate. PM detachment and collection were conducted in a single step. PM-coated air filters …
