Comparative Plasma Proteomics In Muscle Atrophy Induced By Cancer Cachexia And Hindlimb Unloading, Kirsten Rene Dunlap
Comparative Plasma Proteomics In Muscle Atrophy Induced By Cancer Cachexia And Hindlimb Unloading, Kirsten Rene Dunlap
Graduate Theses and Dissertations
Introduction: Muscle atrophy results from a dysfunction in protein turnover that leads to loss of mass and function and occurs concurrently with multiple pathologies such as cancer and extended bed rest. Atrophy reduces overall quality of life while increasing morbidity and mortality. Currently, efficacious therapeutic interventions to treat and prevent muscle wasting in all its forms are lacking, however if conserved mechanisms can be identified between wasting conditions, this would aid in the development of multipurpose therapeutics to ameliorate this pathology. Purpose: To examine circulating factors present across atrophic pathologies. Methods: 35 male C57BL/6J mice were assigned to hindlimb unloading …
Determination Of Adamts13 Susceptibility In Type Iia Von Willebrand Disease, Monica Buselli
Determination Of Adamts13 Susceptibility In Type Iia Von Willebrand Disease, Monica Buselli
Dissertations, Masters Theses, Capstones, and Culminating Projects
von Willebrand Disease (vWD) is a bleeding disorder caused by a deficiency in von Willebrand Factor (vWF), a large glycoprotein that assists in coagulation. Specifically, large vWF multimers in the blood stream are key components in starting the coagulation cascade. vWF is cleaved by the metalloprotease ADAMTS13, regulating the multimers size, which hinders vWF’s ability to function properly. The three main types of vWD —Type I, II, and III— are not well defined, and as a result are all similarly treated with plasma-derived vWF replacement therapy. Plasma-derived vWF is a treatment that does not cure the problem but relieves the …
Comparative Proteomics: Assessing The Variation In Molecular Physiology Within The Adductor Muscle Between Mytilus Galloprovincialis And Mytilus Trossulus In Response To Acute Heat Stress, Joshua Scott Mier
Master's Theses
Increases in seawater temperatures have imposed physiological constraints which are partially thought to contribute to recently observed shifts in biogeographic distribution among closely related intertidal ectotherms. For instance, Mytilus galloprovincialis an introduced warm-adapted species from the Mediterranean, has displaced the native cold-adapted congener, M. trossulus, over large latitudinal expanses off the California coast. Several comparative physiological studies have revealed interspecific differences in thermal tolerance, including variation in aerobic metabolism and gape behavior, which suggest the invasive congener is better adapted to acclimate to increasing seawater conditions as predicted due to climate change. However, current analyses seek to discover the …
Proteomic Analysis Of The Crustacean Molting Gland (Y-Organ) Over The Course Of The Molt Cycle, Talia B. Head
Proteomic Analysis Of The Crustacean Molting Gland (Y-Organ) Over The Course Of The Molt Cycle, Talia B. Head
Master's Theses
Molting in crustaceans is a highly complex physiological process involving negative regulation by two paired endocrine glands, the X-organ/sinus gland complex (XO/SG) and the Y-organ (YO). The XO/SG complex is responsible for making molt-inhibiting hormone (MIH) which negatively regulates synthesis of the molting hormones, ecdysteroids, by the YO. Analysis of gene expression in the XOs and YOs has led to the development of a proposed molecular signaling pathway which regulates ecdysteroidogenesis and subsequent molting in crustaceans. In this study, changes in protein abundance in the YO were characterized over the course of a molt cycle (intermolt, early premolt, mid premolt, …
The Proteomic Response Of Gill Tissue In Tidally And Subtidally-Acclimated California Mussels, Mytilus Californianus, To Acute Emersion-Induced Anoxia, Aubrie N. Fowler, Lars Tomanek
The Proteomic Response Of Gill Tissue In Tidally And Subtidally-Acclimated California Mussels, Mytilus Californianus, To Acute Emersion-Induced Anoxia, Aubrie N. Fowler, Lars Tomanek
Master's Theses
Intertidal mussels regularly experience emersion-induced anoxia, in contrast to normoxic conditions experienced during submersion. We therefore hypothesized that acclimation to a tidal rhythm, as opposed to a rhythm of constant submersion, preconditions the proteome of the California mussel, Mytilus californianus, to respond differently to emersion-induced anoxia. Following acclimation, mussels either continued to receive the acclimation conditions (control) or were exposed to 100% nitrogengas (anoxia) during aerial emersion. We collected gill tissue for subsequent analysis of protein abundance with 2D gel electrophoresis and protein identification with tandem mass spectrometry. Relative to subtidally-acclimated mussels, tidally-acclimated mussels showed a greater propensity to …
Multi-Stress Proteomics: The Global Protein Response To Multiple Environmental Stressors In The Porcelain Crab Petrolisthes Cinctipes, Michael A. Garland
Multi-Stress Proteomics: The Global Protein Response To Multiple Environmental Stressors In The Porcelain Crab Petrolisthes Cinctipes, Michael A. Garland
Master's Theses
Global climate change is increasing the number of hot days along the California coast as well as increasing the incidence of off-shore upwelling events that lower the pH of intertidal seawater; thus, intertidal organisms are experiencing an increase in more than one stress simultaneously. This study seeks to characterize the global protein response of the eurythermal porcelain crab Petrolisthes cinctipes to changes in thermal, pH, and tidal regime treatments, either combined or individually. The first experiment examined temperature stress alone and sought to determine the effect of chronic temperature acclimation on the acute heat shock response. We compared the proteomic …

Molting in crustaceans is a highly complex physiological process involving negative regulation by two paired endocrine glands, the X-organ/sinus gland complex (XO/SG) and the Y-organ (YO). The XO/SG complex is responsible for making molt-inhibiting hormone (MIH) which negatively regulates synthesis of molting hormones (ecdysteroids) by the YO. Eyestalk ablation (ESA) removes the source of MIH and provides an experimental means to manipulate and induce molting, although the physiological effects of ESA on the YO have not been fully characterized. Analysis of gene expression in the XOs and YOs has lead to the development of a proposed molecular signaling pathway which …
The Proteomic Response Of Sea Squirts (Genus Ciona Congeners) To Hyposalinity Stress, James S. Koman
The Proteomic Response Of Sea Squirts (Genus Ciona Congeners) To Hyposalinity Stress, James S. Koman
Master's Theses
The ascidian species Ciona savignyi and C. intestinalis are invasive species but show interspecific differences in their population response to hypo-saline stress associated with heavy winter-run off events that are predicted to become more frequent due to climate change. Despite an almost world-wide distribution, C. intestinalis seems to be more susceptible to hypo-saline stress than the geographically more limited C. savignyi. Given that the genomes of both species are fully sequenced, we were able to compare their proteomic response to both acute and chronic salinity to characterize the mechanisms that are responsible for setting tolerance limits to hyposaline conditions …
