Skeletal muscle insulin resistance is one of the main contributors to Type 2 Diabetes (T2D), which is a chronic disease affecting 37.3 million people in United States (US), with an estimated annual cost exceeding $300 billion in the US. T2D is being treated with a variety of medications, including Pioglitazone (PIO), a potent insulin sensitizer for skeletal muscle. PIO is a synthetic ligand for the peroxisome proliferator-activated receptor (PPAR-γ), nuclear receptors regulating the expression of many genes involved in lipid and glucose metabolism. To date, the molecular action of PIO that sensitizes muscle to insulin is incompletely understood. Protein phosphorylation …


Determining The Effects Of Chemical Exposure On Hepatocyte Mitochondrial Networks And Cell Viability, Bethany Eaton Jan 2022

Determining The Effects Of Chemical Exposure On Hepatocyte Mitochondrial Networks And Cell Viability, Bethany Eaton

All Master's Theses

Mitochondria are cellular organelles that are becoming more recently studied. One of their main functions is the production of energy through cellular respiration, which is crucial to cell life. However, they are also associated with numerous disease states. It is hypothesized that reactive oxygen species (ROS), largely produced in mitochondria, induce oxidative stress and affect mitochondrial morphology along with cell viability. This study compares chemical exposure of menadione, an ROS producer, and phthalates (plasticizers) on two mouse hepatocyte cell lines to determine the effects they have on mitochondrial morphology and cell viability. Three experiments were performed to analyze the effects …

Ethanol (EtOH), in combination with thermal burn injury, is a clinically significant problem resulting in an increase in morbidity and mortality due to acute multi-organ toxicity from excess systemic cytokine release. This intoxicated thermal burn affects close to 50% of the total numbers of hospital-admitted burn patients and currently has no standard treatment. However, using in vitro cellular and in vivo murine models, our group has provided data implicating the augmented production of the lipid mediator Platelet-activating factor (PAF) in keratinocytes in response to intoxicated thermal burn injury in the subsequent pathology. Of importance, our group has demonstrated that activation …


Ahr-Mediated Transcriptional Regulation Of The Human Immunoglobulin Hs1.2 Enhancer, Sydney White Jan 2022

Ahr-Mediated Transcriptional Regulation Of The Human Immunoglobulin Hs1.2 Enhancer, Sydney White

Browse all Theses and Dissertations

The 3'IGHRR is thought to be responsible for the transcription of the immunoglobulin heavy chain (IGH) gene locus, which is essential for the production of antibodies. The human 3’IGHRR, which is duplicated in humans, contains the hs3, hs4, and hs1.2 enhancers. Additionally, the hs1.2 enhancer is polymorphic in humans and consists of a 53 bp invariant sequence that can be repeated one to four times. Previous experiments in a mouse and human B-cell line model have shown that the high affinity AhR ligand and environmental toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) can induce hs1.2 enhancer activity in an AhR-dependent manner. The AhR is …

The Role Of Human Dopamine Transporter Threonine 261 And Serine 262 In Amphetamine Regulation Of Transporter Function And Surface Expression, Sina Abdollahi

Theses and Dissertations

Amphetamine (AMPH) has been used clinically and recreationally around the world for years. A 2021 study reports a 67.5% rise in AMPH use from 2010-2017 across all fifty states. Study also shows that 30% of patients with AMPH-induced psychosis end up with primary psychosis over time. AMPH works by inhibiting monoamine (Norepinephrine (NE), Serotonin (5-HT), and Dopamine (DA) reuptake followed by triggering transporter mediated monoamine release and consequently increases monoamine concentrations in extracellular synaptic space. AMPH also works as a substrate for monoamine transporters, enters the neuron, and once its inside the neuron, it will prevent the storage of monoamines …

Master of Science in Forensic Science Directed Research Projects

In the past 20 years, the rate of opioid use increased drastically in the United States. The country has experienced an enormous number of deaths caused by opioid overdose, opioid use disorder (OUD), as well as other harms as a consequence of the high numbers of opioid prescriptions. Fentanyl, a well-known synthetic opioid, has been a contributor to the opioid crisis since 2013 due to its popularity in clinical and illicit use. It has a high potency, which makes it an effective analgesic but a dangerous illicit substance. A new synthetic opioid, bucinnazine, has recently become a new black-market opioid …


Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich Jan 2022

Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich

Harold W. Manter Laboratory of Parasitology: Library Materials

Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centered on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although the significance of this intersection is not properly appreciated. Human beings are part of biodiversity and elements in a global ecosystem. Civilization, and perhaps even the fate of our species, is utterly dependent on that ecosystem’s proper functioning, which society is increasingly degrading. The crisis seems rooted in three factors. First, relatively few people globally are aware of its existence. Second, most people who …

Impacts Of Plastic Pollution On A Pelagic Marine Mammal, The Northern Elephant Seal, Lauren M. Kashiwabara

University of the Pacific Theses and Dissertations

As plastic pollution increases, top marine predators such as marine mammals are becoming increasingly susceptible to plastic particles and their additives. Plastic particles have been found in gastrointestinal tracts and scat of many marine mammals, and quantifying plastic pollution in those that are pelagic can provide insight into plastic pollution in mesopelagic ecosystems that are just beginning to be analyzed. Adapting well-developed laboratory techniques for microplastic (MP) isolation (i.e. density separation and chemical digestion), I isolated MPs from the scat of the deepest diving pinniped, the northern elephant seal (NES), and found that100% of scat samples (n=11) contained high counts …

Longitudinal Patterns Of Microplastic Abundance And Potential For Food Web Uptake In The Yakima River, Janell Shah

All Master's Theses

Microplastic (MP) pollutes environments worldwide, but the ecological consequences remain largely unknown. While MP research has historically focused on marine environments, recent work has increasingly investigated rivers as transporters of MP from terrestrial sources to the ocean. Some studies have documented instances of MP consumption in a river food web, but few have investigated multiple consumers at different points along a river continuum. This study enumerated the MP abundance in the water column, biofilm, and four macroinvertebrate families from different functional feeding groups across nine sites spanning 344 kilometers from the headwaters to the mouth of the Yakima River in …

Faculty, Staff and Student Publications

Uveal coloboma is a condition defined by missing ocular tissues and is a significant cause of childhood blindness. It occurs from a failure of the optic fissure to close during embryonic development and may lead to missing parts of the iris, ciliary body, retina, choroid, and optic nerve. Because there is no treatment for coloboma, efforts have focused on prevention. While several genetic causes of coloboma have been identified, little definitive research exists regarding the environmental causes of this condition. We review the current literature on environmental factors associated with coloboma in an effort to guide future research and preventative …

The Thai Journal of Pharmaceutical Sciences

Objectives: The pharmacological basis of anti-inflammatory agents is geared toward maintaining body homeostasis. This study investigated the scientific underpinning and mechanisms of anti-inflammatory activity of root bark of Brenania brieyi. Material and Methods: The plant material was extracted with a mixture of methanol and chloroform (2:1) and fractionated with 0.2 volume water. Egg albumin-induced edema and cotton pellet-induced granuloma models were used to investigate anti-inflammatory activity while the possible mechanisms of actions were evaluated using standard methods. Results: Significant (P < 0.05) reduction in edema and granuloma tissue formation were recorded in fractions treated groups compared with the normal control. There was a significant (P < 0.05) inhibition of membrane hemolysis and phospholipase A2 (PLA2) activity by the fractions compared with the standard drugs, indomethacin, and prednisolone, respectively. Both fractions significantly (P < 0.05) inhibited prostaglandin (PG) synthase and nitric oxide radical activities compared with the control. However, varying doses of both fractions did not inhibit leukocyte migration compared with rats in indomethacin and control groups. The methanol fraction was found to be more potent in most of the tests. Conclusion: These results show that B. brieyi root bark has anti-inflammatory activity, and the potential underlying mechanisms of its action are inhibition of PLA2 and PG involved in inflammatory responses.
