The Effects Of Rolipram, A Selective Phosphodiesterase Inhibitor, On Immortalized Schwann Cell Proliferation, Akap95 And Cyclin D3 Expression, Kyle P. Kenney, Mary Pistack, Angela Asirvatham
The Effects Of Rolipram, A Selective Phosphodiesterase Inhibitor, On Immortalized Schwann Cell Proliferation, Akap95 And Cyclin D3 Expression, Kyle P. Kenney, Mary Pistack, Angela Asirvatham
Student Research Poster Presentations 2021
Schwann cells are a vital component of the Peripheral Nervous System and aid in the repair of axons following injury. The regulation of Schwann cell growth in vitro is facilitated by heregulin, a neuron-secreted growth factor, and an unknown mitogen that activates the cyclic adenosine monophosphate (cAMP) pathway. The abundance of intracellular cAMP is regulated by a family of enzymes called phosphodiesterases (PDEs). PDE inhibitors such as rolipram have therapeutic potential in various disorders and function by increasing the levels of intracellular cAMP. A-Kinase anchoring proteins (AKAPs), a family of scaffolding proteins that belong to the cAMP/Protein Kinase A (PKA) …
Quantitated Effects Of Nutritional Supplementation On Exercise Induced Sweat, Andrew Blake Austin Browder
Quantitated Effects Of Nutritional Supplementation On Exercise Induced Sweat, Andrew Blake Austin Browder
Browse all Theses and Dissertations
Discovery studies have identified many metabolites contained in human sweat. However, quantitative analysis of the sweat metabolome content remains mostly unknown. Furthermore several attributes, including rate, have been defined to affect sweat metabolite content, while other effectors, like diet, remain unknown. This study works to quantitatively define the metabolite impact caused by nutritional supplementation. To better understand the effect diet plays, a LC-MS method was developed focusing on improving resolution and peak width. While the literature provided examples of how diet affected sweat metabolite concentrations, the long-term effects of diet have not been explored. The experiment described here attempts to …

Microsatellites And Their Association With Break Induced Replication, French J. Damewood Iv

To study microsatellites instability and their repair pathways a dual fluorescent (DF2) and selectable (ganciclovir sensitive/ thymidine kinase (TK) expressing) cell system was assayed using replication fork stalling agents hydroxyurea and telomestatin. These cell lines carried ectopically integrated microsatellites derived from the Dystrophia Myotonica Protein Kinase (DMPK) gene ((CTG)102 microsatellite), or an 88 bp polypurine/ polypyrimidine (Pu/Py) repeat from the PKD-1 locus, inserted into a FLP recombinase target site. These microsatellites form non-B DNA structures in -vivo and in-vitro causing replication fork stalling and double strand breaks. DF2 myc (CTG)102 -TK cells treated with hydroxyurea were assayed for mutagenesis of …
Potential Drug Treatment For Duchenne Muscular Dystrophy Which Could Be Through Upregulation Of Lipin1, Rajsi Y. Thaker
Potential Drug Treatment For Duchenne Muscular Dystrophy Which Could Be Through Upregulation Of Lipin1, Rajsi Y. Thaker
Browse all Theses and Dissertations
Duchenne muscular dystrophy (DMD) is a genetic disorder leading to progressive muscle degeneration and weakness due to mutation in dystrophin gene, which is very important for maintaining muscle membrane integrity. Dystrophin is the largest gene in the human genome therefore more prone to mutation. There is currently no cure for DMD. Our lab recently found that Lipin1 deficient myofibers showed upregulation of necroptosis correlated with the loss of muscle membrane integrity. Our primary approach for ameliorating dystrophic phenotype in DMD is through reduction of necroptosis using drugs which can potentially upregulate Lipin1 expression. In this study, we identified two drugs …

Extracellular signal-regulated kinase 3 (ERK3) is a member of the atypical mitogen-activated protein kinase (MAPK) subfamily, whose members have been shown to play important roles in a number of cellular processes including proliferation, differentiation, migration, and apoptosis. While signals regulating ERK3 kinase activity remain unclear, ERK3 is known to be an unstable protein with function tightly regulated via ubiquitination and proteasomal turnover. The deubiquitinating enzyme USP20 has been shown to regulate ERK3 by stabilizing the kinase, but presently, no destabilizing ubiquitin ligases have been identified. The SKP1-CUL1-F-box protein (SCF) E3 ligases are a subfamily of ubiquitin E3 ligases composed of …
Development Of Linked-Domain Protein Inhibitors Of The E2-Conjugating Enzyme Ube2d, Anneroos E. Nederstigt
Development Of Linked-Domain Protein Inhibitors Of The E2-Conjugating Enzyme Ube2d, Anneroos E. Nederstigt
University of the Pacific Theses and Dissertations
In most eukaryotic organisms, the ubiquitination pathway is one of the most important and versatile signaling systems in use. It is integral to processes such as protein degradation and homeostasis, DNA repair cell cycle regulation, signaling and regulation, epigenetics, and many more. Ubiquitin (Ub) is a short polypeptide of 8.6 kDa, 76 residues that functions as a reversible post-translation modification (PTM). It furthermore contains 7 different lysine residues (K6, K11, K27, K29, K33, K48, K63), all of which can form isopeptide linkages with one another to link individual Ub moieties to form unique polyUb chains onto substrates. The type of …

Study Of Student Resource Use In Introductory Chemistry Courses, Sarah E. Melvin
Electronic Theses and Dissertations
According to the U.S. Government Accountability Office (GAO), college textbook prices have increased by 186% from 1986 to 2004.1 The impact of rising cost of textbooks is increasingly apparent as students are becoming more selective in the courses they enroll in, as well as more concerned with the quality of the learning experience they receive once enrolled in a course.1 In response to high textbook prices, open-education resources (OER) are increasingly becoming more accepted for student use as an alternative to traditional textbook options. OERs are open-source textbook and/or materials that are free to use without worrying about copyright …
