Phosphodiesterase Isoforms And Camp Compartments In The Development Of New Therapies For Obstructive Pulmonary Diseases, Martina Schmidt, Isabella Cattani-Cavalieri, Francisco J. Nuñez, Rennolds S. Ostrom

Pharmacy Faculty Articles and Research

The second messenger molecule 3′5′-cyclic adenosine monophosphate (cAMP) imparts several beneficial effects in lung diseases such as asthma, chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). While cAMP is bronchodilatory in asthma and COPD, it also displays anti-fibrotic properties that limit fibrosis. Phosphodiesterases (PDEs) metabolize cAMP and thus regulate cAMP signaling. While some existing therapies inhibit PDEs, there are only broad family specific inhibitors. The understanding of cAMP signaling compartments, some centered around lipid rafts/caveolae, has led to interest in defining how specific PDE isoforms maintain these signaling microdomains. The possible altered expression of PDEs, and thus abnormal …

Thermotropic And Lyotropic Phase Behaviours Of Spontaneously Self-Assembled Amphiphilic Branched-Chain Glycosides With Various Chain Length, Abdul Hamid Hairul Amani

Student Works (2020-2029)

Lipid polymorphism is a process which illustrates the self-assembly of lipid aggregation depending on the environment. Lipids such as branched-chain glycolipids which are amphiphilic molecules also known as amphitropic tend to generate mesophases in thermotropic (dry) and lyotropic (solvation) conditions. These molecules are capable of self-aggregating into various types of glycolipid self-assemblies offering an interesting insight in relation to their functions in living cells. Hence, this study aims to investigate the mesophases of ꞵ-D-glycosides which are branched-chain synthetic glycolipids, namely, ꞵ-D-glucosides and ꞵ-D-maltosides. The study was carried out on the thermotropic phases of dry glycosides and the lyotropic phases of …

Targeting The Transferrin Receptor To Develop Erythropoietin For Alzheimer’S Disease, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

"Alzheimer’s disease (AD) is the sixth leading cause of death in the United States with approximately 5.8 million Americans currently living with AD. Due to the lack of a disease modifying treatment for AD and the aging baby boomer generation, this number is projected to grow to 13.8 million by 2050 (Gaugler et al., 2019). Amyloid-beta (Aβ) plaque accumulation, one of the major pathological hallmarks of AD, can begin > 20 years before clinical symptoms of AD. By the time AD is clinically diagnosed, neuronal loss and neuropathological lesions (Aβ plaques and tau tangles) have already occurred in many brain regions …

Pharmacy Faculty Articles and Research

Primary cilia are shown to have membrane swelling, also known as ciliary bulbs. However, the role of these structures and their physiological relevance remains unknown. Here, it is reported that a ciliary bulb has extracellular vesicle (EV)‐like characteristics. The ciliary extracellular‐like vesicle (cELV) has a unique dynamic movement and can be released by mechanical fluid force. To better identify the cELV, differential multidimensional proteomic analyses are performed on the cELV. A database of 172 cELV proteins is generated, and all that examined are confirmed to be in the cELV. Repressing the expression of these proteins in vitro and in vivo …

Translational Regulation Of Environmental Adaptation In Bacteria, Rodney Tollerson Ii, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Bacteria must rapidly respond to both intracellular and environmental changes to survive. One critical mechanism to rapidly detect and adapt to changes in environmental conditions is control of gene expression at the level of protein synthesis. At each of the three major steps of translation—initiation, elongation, and termination—cells use stimuli to tune translation rate and cellular protein concentrations. For example, changes in nutrient concentrations in the cell can lead to translational responses involving mechanisms such as dynamic folding of riboswitches during translation initiation or the synthesis of alarmones, which drastically alter cell physiology. Moreover, the cell can fine-tune the levels …

Recombinant Human Proteoglycan-4 Mediates Interleukin-6 Response In Both Human And Mouse Endothelial Cells Induced Into A Sepsis Phenotype, Holly A. Richendrfer, Mitchell M. Levy, Khaled A. Elsaid, Tannin A. Schmidt, Ling Zhang, Ralph Cabezas, Gregory D. Jay

Pharmacy Faculty Articles and Research

Objectives:

Sepsis is a leading cause of death in the United States. Putative targets to prevent systemic inflammatory response syndrome include antagonism of toll-like receptors 2 and 4 and CD44 receptors in vascular endothelial cells. Proteoglycan-4 is a mucinous glycoprotein that interacts with CD44 and toll-like receptor 4 resulting in a blockade of the NOD-like receptor pyrin domain-containing-3 pathway. We hypothesized that endothelial cells induced into a sepsis phenotype would have less interleukin-6 expression after recombinant human proteoglycan 4 treatment in vitro.

Design:

Enzyme-linked immunosorbent assay and reverse transcriptase-quantitative polymerase chain reaction to measure interleukin-6 protein and gene expression.

Setting: …

Designing Peptides To Bind Kappa B Dna And Mimic Nf-Kappa B Protein Complexes, Nicholas A. Markowich

Honors College Theses

Transcription factors are important proteins that regulate gene expression and protein synthesis. Transcription factors can either boost the gene’s transcription rate by helping RNA polymerase activate transcription or restrict it by interfering with RNA polymerase, thereby repressing transcription. Nuclear factor-kappa-B (NF-κB) transcription factors are a family of proteins that control the synthesis of proteins involved in many cellular processes such as inflammatory and immune responses, cell growth, and apoptosis. However, the overexpression and activation of these transcription factors is linked to deadly conditions such as cancer and neurodegenerative diseases which currently have few safe cures. The goal of this research …

Determining The Link Between Advanced Glycation Endproducts (Ages), Feeding, And Metabolism, Lauren Wimer

Natural Sciences and Mathematics | Biological Sciences Master's Theses

Reactive a-dicarbonyls (a-DC’s), such as methylglyoxal (MGO), are unavoidable metabolites generated during glycolysis that accumulate with age and have been linked with chronic age-related metabolic diseases such as Diabetes Mellitus. Diabetes Mellitus is generally characterized by peripheral neuropathy and sustained hyperglycemia. Chronic hyperglycemia leads to an increase in glycolysis and a downstream increase in reactive a-DC’s. The human body has a natural method of detoxifying these a-DC’s. Glycolytic cells have enzymes which can detoxify a-DC’s, but if overwhelmed, a-DC’s can accumulate and react non-enzymatically with proteins, lipids and DNA to yield a group of molecules called advanced glycation end-products (AGEs). …
