Quantum Dots' Toxicity: A Multi-Level Investigation On The Impact Of Quantum Dots On The Actin Cytoskeleton, Nhi Le
MSU Graduate Theses
Quantum dots (QDs) are fluorescence nanomaterials with unique optical and physical properties. As such, they are highly sought after for their potential use in several biomedical and industrial applications. Despite their vast potential, recent studies have suggested that quantum dots are toxic to cells. Yet, the mechanism of quantum dots’ toxicity remains unclear. As such, my thesis aims to comprehensively examine the mechanism of quantum dots’ toxicity, emphasizing how quantum dots disrupt the actin cytoskeleton. In this study, I used RNA sequencing and mass spectrometry to investigate the influence of CdSe/ZnS QDs on the transcriptomic proteomic level of Saccharomyces cerevisiae …
Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas
Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas
MSU Graduate Theses
The first line of defense against bodily insults, like pathogen invasion, is the innate immune system. Innate immunity sets in motion countless cascades that result in inflammation. Inflammation simultaneously affects multiple biological processes like metabolism and gene expression. Males and females react differently to inflammation. To understand both molecular and physiological sex differences in inflammation, we examined how inflammation affects gene expression and glucose metabolism. Adenosine deaminase acting on RNA (ADAR1) is upregulated by inflammation and catalyzes RNA editing, a process where nucleotides encoded by the genome are modified. ADAR1 also controls the innate immune reaction by decreasing activity of …

A Study Of Cobalt (Iii) Oxide Nanoparticle Delivery Of Sirna Molecules Directed Against Signaling Intermediates Of The P2y2 Receptor, Rachel Blair Stroud
MSU Graduate Theses
G protein-coupled receptors are evolutionarily ubiquitous sensors of extracellular signals, propagating intracellular signal cascades through heterotrimeric G proteins. P2Y2 receptors are GPCRs which are activated by extracellular nucleotides to mediate signaling cascades via Gαq coupling. Many GPCRs are subject to a common mechanism for signal termination involving phosphorylation of the C-terminal tail followed by β-arrestin binding and subsequent endocytic internalization of the complex. This effect has been described for the P2Y2 R in the 1321N1 astrocytoma cell line, and UTP-induced activation and desensitization profiles have been previously defined. There is need to develop molecular vehicles for safe and …
Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino
Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino
MSU Graduate Theses
Recent insights into the pathological role of Nucleotide P2Y2 receptor suggest P2Y2R involvement in high fat diet-induced obesity and potentiates insulin resistance. However, these recent insights do not demonstrate how P2Y2R modulates glucose homeostasis under physiological conditions. Further, it remains unknown how sex biological factors influence P2Y2R receptor signaling in the regulation of glucose homeostasis. The research objective for the present study is to elucidate the novel roles of P2Y2 in fasting blood glucose and glucose tolerance (basal insulin sensitivity) under resting conditions in males and females. We expected that under physiological …
Nucleotide P2y₂ Receptor-Dependent Leukocyte-Endothelial Interaction, Spencer E. Thomas
Nucleotide P2y₂ Receptor-Dependent Leukocyte-Endothelial Interaction, Spencer E. Thomas
MSU Graduate Theses
Extracellular nucleotides (ATP, UTP) released from cells act on nucleotide receptors to promote vascular inflammation. Increased leukocyte-endothelial interaction is a hallmark of vascular inflammation. The nucleotide P2Y₂ receptor (P2Y₂R), activated by extracellular ATP≈UTP, plays a role in cardiovascular homeostasis and immune regulation. Moreover, accumulating evidence from studies in vitro and in vivo models have implicated the P2Y₂R in the inflammatory response significantly contributing to the progression and pathogenesis of asthma, atherosclerosis, sepsis, and ischemia. I hypothesized that P2Y₂R activation by UTP, an agonist of the receptor, increased leukocyte rolling and adhesion in the microvasculature from baseline. To test the hypothesis, …

Further Characterization Of The Skeletal Phenotype In A Hurler Syndrome Mouse Model And The Ethical Treatment Of Children In Medicine, Anna Marie Mcwoods
MSU Graduate Theses
Mucopolysaccharidosis type I (MPS I) is a rare, autosomal recessive disorder caused by the deficiency of the lysosomal enzyme α-L-iduronidase (IDUA). Absence of IDUA results in the accumulation of dermatan and heparin sulfate and ultimately causes multi-system dysfunction. The most severe form of MPS I is Hurlers syndrome, a rapidly progressive disorder that, if left untreated, is fatal. Current treatment options for diagnosed individuals includes hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT). These treatments are able to ameliorate the majority of symptoms with the exception of the bone phenotype. This investigation aimed to further characterize the bone …
