A Study Of Cobalt (Iii) Oxide Nanoparticle Delivery Of Sirna Molecules Directed Against Signaling Intermediates Of The P2y2 Receptor, Rachel Blair Stroud
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 …
Characterization Of Nanoparticles Using Inductively-Coupled Plasma Mass Spectrometry, Jabez D. Campbell
Characterization Of Nanoparticles Using Inductively-Coupled Plasma Mass Spectrometry, Jabez D. Campbell
MSU Graduate Theses
Nanomaterials are a relatively new class of materials that have many applications which span a wide host of fields from medical products to consumer products. The possible compositions and forms of nanomaterials are just as varied as the applications. Therefore, a versatile characterization method is needed for researchers and regulators alike to ensure nanomaterials are properly used. Single Particle Inductively Coupled Plasma Mass Spectrometry (SP-ICP-MS) is a functional method that could fill the characterization need in the nanomaterial research field. Using data from both SP-ICP-MS tests and data from literature established characterization methods, the viability of making SP-ICP-MS the standard …
Identifying And Comparing Transcriptome Alterations In Saccharomyces Cerevisiae Exposed To A Variety Of Quantum Dots, Cullen Horstmann
Identifying And Comparing Transcriptome Alterations In Saccharomyces Cerevisiae Exposed To A Variety Of Quantum Dots, Cullen Horstmann
MSU Graduate Theses
The primary focus of my research was to obtain global gene expression profiles of baker’s yeast exposed to sub-lethal doses of nanoparticles, such as silver nanoparticles (AgNPs), yellow- emitting CdSe/ZnS quantum dots (QDs), green-emitting CdSe/ZnS QDs, and InP/ZnS QDs, to reveal novel insights on their unique mechanisms of toxicity. Despite their diverse applications, their long-lasting effects on the environment and human health are not well understood. To assess their toxicity, I administered experiments that exposed Saccharomyces cerevisiae to a variety of nanoparticles and measured cell viability, ROS levels, and changes in gene expression. Most notably, I used RNA-sequencing (RNA-seq) to …
