Autosomal dominant polycystic kidney disease (ADPKD) is an inherited genetic disorder that results in progressive renal cyst formation with ultimate loss of renal function and other systemic disorders. These systemic disorders include abnormalities in cardiovascular, portal, pancreatic and gastrointestinal systems. ADPKD is considered to be among the ciliopathy diseases due to the association with abnormal primary cilia function. In order to understand the full course of primary cilia and its association with ADPKD, the structure, functions and role of primary cilia have been meticulously investigated. As a result, the focus on primary cilia has emerged to support the vital roles …


Rhodopsin Trafficking And Retinal Function, Nicholas Joseph Reish Jan 2013

Rhodopsin Trafficking And Retinal Function, Nicholas Joseph Reish

All ETDs from UAB

The health and maintenance of rod photoreceptors depends on the high-fidelity vectorial transport of rhodopsin from its site of synthesis in the inner segment to its final resting place in the outer segment disks. Multiple molecular interactions play a role in this process, including the interaction of the small GTPase rab11a with rhodopsin that was first described in vertebrates in amphibians. We found that the interaction of the small GTPase rab11a and rhodopsin is conserved in mammalian retina. This interaction is direct, is abrogated by human disease-causing truncation mutations in rhodopsin, and does not depend on the nucleotide binding status …


Gabaergic Dysfunction In Huntington Disease, Sarah Elizabeth Dougherty Jan 2013

Gabaergic Dysfunction In Huntington Disease, Sarah Elizabeth Dougherty

All ETDs from UAB

GABAergic neurons are responsible for regulation of neuronal signaling through inhibition. Alterations in the delicate balance of excitation and inhibition have been observed in many neurological disorders, including neurodegenerative diseases. Huntington disease (HD) is an autosomal dominant neurodegenerative disorder that is characterized by motor, psychiatric, and cognitive disturbances. As the hallmark movement pathology of HD is hyperkinesis it is intriguing to postulate that alterations in inhibition, and by extension within GABAergic cell networks, could be part of the pathogenesis of this disorder. In order to elucidate the role of GABAergic cell populations in HD we have used behavioral paradigms, molecular …

Saha Cardiovascular Research Center Faculty Publications

Studies suggest that inflammation impairs reverse cholesterol transport (RCT). We investigated whether serum amyloid A (SAA) contributes to this impairment using an established macrophage-to-feces RCT model. Wild-type (WT) mice and mice deficient in SAA1.1 and SAA2.1 (SAAKO) were injected intraperitoneally with 3H-cholesterol-labeled J774 macrophages 4 hr after administration of LPS or buffered saline. 3H-cholesterol in plasma 4 hr after macrophage injection was significantly reduced in both WT and SAAKO mice injected with LPS, but this was not associated with a reduced capacity of serum from LPS-injected mice to promote macrophage cholesterol efflux in vitro. Hepatic accumulation of 3 …


Thc-Mediated Induction Of Δfosb And Its Modulation Of Cb1r Signaling And Adaptation, Lazenka Matthew Jan 2013

Thc-Mediated Induction Of Δfosb And Its Modulation Of Cb1r Signaling And Adaptation, Lazenka Matthew

Theses and Dissertations

The main psychoactive and therapeutic effects of Δ9-tetrahydrocannabinol (THC) are mediated through cannabinoid type 1 receptors (CB1Rs). The therapeutic uses of THC are mitigated by the development of tolerance to these therapeutic effects, whereas tolerance does not readily develop to some of the side-effects of THC, like motor impairment and reward. The development of tolerance occurs through adaptations at CB1Rs, which include desensitization (G-protein uncoupling) and downregulation (receptor degradation). Brain region-dependent differences in THC-mediated adaptations are proposed to explain the differences in tolerance to various THC-mediated effects. These studies focused on whether ΔFosB, a stable transcription factor, could regulate CB1R …

The Characterisation Of Pax3 Expressant Cells In Adult Peripheral Nerve [Journal Article], Judith Blake, Melanie Ziman Jan 2013

The Characterisation Of Pax3 Expressant Cells In Adult Peripheral Nerve [Journal Article], Judith Blake, Melanie Ziman

Research outputs 2013

Pax3 has numerous integral functions in embryonic tissue morphogenesis and knowledge of its complex function in cells of adult tissue continues to unfold. Across a variety of adult tissue lineages, the role of Pax3 is principally linked to maintenance of the tissue’s resident stem/progenitor cell population. In adult peripheral nerves, Pax3 is reported to be expressed in nonmyelinating Schwann cells, however, little is known about the purpose of this expression. Based on the evidence of the role of Pax3 in other adult tissue stem and progenitor cells, it was hypothesised that the cells in adult peripheral nerve that express Pax3 …

Impedance Changes In Biceps Brachii Due To Isometric Contractions And Muscle Fatigue Using Electrical Impedance Myography (Eim), Travis Orth

College of Graduate Studies: Theses & Dissertations

Electrical impedance myography (EIM) is a non-invasive technique used to evaluate neuromuscular conditions by using a quantitative parameter called impedance (Z). It relies upon the application and measurement of high-frequency, low-intensity electrical current imbedded over a localized muscle to determine its opposition to current flow. In brevity, impedance determines the resistance of muscle fibers due to changes in muscle composition. The objective of this thesis was to establish a relationship between muscles at rest and during isometric contractions at various force levels(25%, 50%, and 100% of maximum voluntary contraction) of the biceps brachii over a multifrequency spectrum. Impedance measurements due …
