Ksrp Ablation Enhances Lipolysis In White Adipose Tissue Through Reduced Mir-145 Expression, Yi-Yu Lin Jan 2014

Ksrp Ablation Enhances Lipolysis In White Adipose Tissue Through Reduced Mir-145 Expression, Yi-Yu Lin

All ETDs from UAB

White adipose tissue (WAT) releases fatty acids from stored triacylglycerol (TAG) for energy source. Here, we report that null mice for KH-type splicing regulatory protein (KSRP), an RNA-binding protein, resisted high fat diet (HFD) induced obesity. Target of deletion of KSRP regulates gene expression at multiple levels and enhances lipolysis in epididymal WAT (eWAT) due to up-regulation of genes promoting lipolytic activity. Expression of miR-145 is decreased due to impaired pri-miR-145 processing in Ksrp-/- eWAT. We show that miR-145 directly targets and represses Foxo1 and Cgi58, activators of lipolytic activity, and forced expression of miR-145 attenuates lipolysis. This study reveals …

Effects Of Cpla-2 On The Migration And Proliferation Of Human Vascular Smooth Muscle Cells And The 2-D Migratory Patterns Of Tropomyosin In Femoral And Abdominal Aorta Tissue, Jaimeson Thomas Powell

Theses and Dissertations

Abstract 1: Platelet derived growth factor BB (PDGF BB) has an important influence on smooth muscle cell proliferation in restenosis and atherosclerosis. Our understanding of different signal transduction pathways involved in the response of smooth muscle cells to PDGF BB is potentially significant for understanding and manipulating these processes. Prior studies have demonstrated a crucial activation of cytosolic phospholipase A2 (cPLA2) in smooth muscle cells to PDGF BB with the production of arachidonic acid and prostaglandin E2. In these studies we investigated the role for another PLA2, calcium-independent PLA2 (iPLA2) in comparison to cPLA2 on smooth muscle cell migration and …

The Impact Of Implementing A Sudden Infant Death Syndrome Education Package In Jordan, Shereen Hamadneh

Theses: Doctorates and Masters

Background: Sudden Infant Death Syndrome (SIDS) is a problem worldwide. In North Jordan, SIDS rate was high as 1.32 per 1,000 live births and contributed 6% to the infant mortality rate (Bataineh, Shawagfeh, & Twalbeh, 2008). However, SIDS risk factors are preventable and can be reduced by improving knowledge and changing relevant behaviours of parents and healthcare providers (American Academy of Pediatrics, 2013; American SIDS Institute, 2011; Bataineh, Hussein Shawagfeh, & Twalbeh, 2008; Bredemeyer, 2004; Grazel, Phalen, & Polomano, 2010b; Moon, Oden, & Grady, 2004; NICHD, 2010). Still educating Jordanians about SIDS has not been a national health policy priority. …

Faculty Publications

Background

Tissue-transglutaminase (TG2), a dual function G-protein, plays key roles in cell differentiation and migration. In our previous studies we reported the mechanism of TG2-induced cell differentiation. In present study, we explored the mechanism of how TG2 may be involved in cell migration.

Methods

To study the mechanism of TG2-mediated cell migration, we used neuroblastoma cells (SH-SY5Y) which do not express TG2, neuroblastoma cells expressing exogenous TG2 (SHYTG2), and pancreatic cancer cells which express high levels of endogenous TG2. Resveratrol, a natural compound previously shown to inhibit neuroblastoma and pancreatic cancer in the animal models, was utilized to …


Determinants Of Upper Genital Tract Complications In A Chlamydial Urogenital Mouse Model, Enitra N. Jones Dec 2013

Determinants Of Upper Genital Tract Complications In A Chlamydial Urogenital Mouse Model, Enitra N. Jones

Theses and Dissertations (ETD)

Genital Chlamydia trachomatis infection is a major public health concern. Chlamydia is the most commonly reported infection in the United States and the most common bacterial sexually transmitted infection worldwide. Unrecognized infection endangers female reproductive health by serious complications such as Pelvic Inflammatory Disease, ectopic pregnancy, and involuntary infertility. Widespread Chlamydia control programs were implemented more than two decades ago to improve women's reproductive health but, despite initial success, the number of chlamydial infections reported have increased.

One of the hypotheses put forth to explain increased chlamydial reporting suggests that a longterm caveat of control initiatives is interference with the …


Sympathetic Nerve Modulation Of Joint Pathology In Adjuvant-Induced Arthritis, Carlo Anthony Wood Dec 2013

Sympathetic Nerve Modulation Of Joint Pathology In Adjuvant-Induced Arthritis, Carlo Anthony Wood

Loma Linda University Electronic Theses, Dissertations & Projects

Background: There is increasing data suggesting a net increase in sympathetic tone plays an important role in rheumatoid arthritis. Several studies have reported altered distribution and density of autonomic nerves in patients with rheumatoid arthritis and animal models for the disease. This provides anatomical evidence that supports a neurally-mediated drive in inflammation and joint destruction. Methods: Adult rats were injected with complete Freund’s adjuvant. At 12 days post immunization, animals were randomly placed into a drug treatment group (SH1293, which interacts with - and ß2-ARs), an adjuvant arthritic group, or a control group. These animals were sacrificed at 14, 21, …

Expression And Function Of Ca2+-Activated K+ Channels In Uterine Arteries, Ronghui Zhu

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic hypoxia during pregnancy is one of the most common insults to the maternal cardiovascular system and fetal development, and is associated with increased uterine vascular tone and heightened risk of preeclampsia and fetal intrauterine growth restriction (IUGR). The present study tested the hypothesis that calcium-activated potassium (KCa) channels play an essential role in uterine vascular adaptation to pregnancy, which is inhibited by chronic hypoxia during gestation. Uterine arteries (UAs) were isolated from nonpregnant ewes (NPUAs) and near-term pregnant ewes (PUAs) that had been maintained at sea level (~300 m) or exposed to high altitude (3,801 m) for 110 days. …


Radiosensitization Of Head & Neck Carcinoma Cells By Linifanib, A Receptor Tyrosine Kinase Inhibitor, Heng-Wei Hsu Dec 2013

Radiosensitization Of Head & Neck Carcinoma Cells By Linifanib, A Receptor Tyrosine Kinase Inhibitor, Heng-Wei Hsu

Loma Linda University Electronic Theses, Dissertations & Projects

Tumor angiogenesis is a hallmark of advanced cancers and promotes invasion and metastasis. Over 90% of head and neck squamous cell carcinomas (HNSCC) express angiogenic factors such as vascular endothelial growth factor (VEGF). Since radiotherapy is one of the most commonly used treatments for HNSCC, it is imperative to identify the interactions between antiangiogenic therapy and radiotherapy, and to develop combination therapy to improve clinical outcome. The mechanisms between antiangiogenic agents and ionizing radiation are complicated and involve many interactions between the vasculature, tumor stroma and tumor cells. The proliferation and metastasis of tumor cells rely on angiogenesis/blood vessel formation. …

A Novel Mechanism Of Enhanced Susceptibility To Bacterial Pneumonia In Influenza-Infected Hosts, Hazem Elsayed Ghoneim

Theses and Dissertations (ETD)

Viruses such as influenza suppress host immune function by a variety of methods. This may result in a significant morbidity through several pathways, including facilitation of secondary bacterial pneumonia from pathogens such as Streptococcus pneumoniae. Lungresident alveolar macrophages (AMs) act as the first line of innate cellular immunity against respiratory bacterial pathogens, including pneumococcus. Therefore, they represent an attractive target for study Before investigating the impact of influenza infection on resident AMs, we first characterized different subsets of lung-resident macrophages in naïve mice using a novel in vivo labeling approach in conjunction with multicolor flow cytometric analysis and confocal microscopic …

Caveolins And Njks Influence Brain Endothelial Permeability After Juvenile Tbi, David Olufemi Ajao Dec 2013

Caveolins And Njks Influence Brain Endothelial Permeability After Juvenile Tbi, David Olufemi Ajao

Loma Linda University Electronic Theses, Dissertations & Projects

Disruption of blood-brain barrier (BBB) is a key secondary event that exacerbates brain damage following traumatic brain injury (TBI). BBB disruption is particularly damaging to the developing brain – which is highly vulnerable to various stress stimuli, resulting in increased brain swelling, disrupted cerebral blood flow (CBF) autoregulation, long-term disabilities and death following TBI in young demographic. Unsurprisingly, BBB disruption and the resultant cerebral edema have emerged as therapeutic targets in juvenile TBI. It is therefore important to understand the molecular players and mechanisms involved in TBI-induced BBB disruption in the juvenile brain. To this end, the endothelial caveolins and …


Contrast Adaptation In The Lateral Eye Of Limulus Polyphemus, Tchoudomira Valtcheva Nov 2013

Contrast Adaptation In The Lateral Eye Of Limulus Polyphemus, Tchoudomira Valtcheva

USF Tampa Graduate Theses and Dissertations

Luminance and contrast adaptation are neuronal mechanisms that the retina applies for continuous adjustment to light sensitivity though a collection of cellular and synaptic mechanisms distributed across the retinal network, thus accommodating the wide input range of the visual system within the constricted output range of retinal ganglion cells. Luminance mean adaptation has been demonstrated in the output neurons of the invertebrate eye (eccentric cells), and the aim of the study was to investigate whether the homology in visual processing extends to luminance variance (contrast) adaptation as well. The spike trains of individual eccentric cells were recorded from live horseshoe …
