Microbiology, Immunology, and Molecular Genetics Faculty Publications

Geotrichum species have been rarely reported as the cause of sepsis, disseminated infection in immunosuppressed patients. The patient we describe developed indolent endophthalmitis four months after her routine right eye cataract surgery. The intraoperative sample from right vitreous fluid grew Geotrichum candidum. The patient underwent vitrectomy, artificial lens explantation and intravitreal injection of amphotericin B followed by oral voriconazole. Despite these interventions, she underwent enucleation. This is the first published case of Geotrichum candidum endophthalmitis.

Azithromycin Drives Alternative Macrophage Activation And Improves Recovery And Tissue Sparing In Contusion Spinal Cord Injury, Bei Zhang, William M. Bailey, Timothy J. Kopper, Michael B. Orr, David J. Feola, John C. Gensel

Spinal Cord and Brain Injury Research Center Faculty Publications

BACKGROUND: Macrophages persist indefinitely at sites of spinal cord injury (SCI) and contribute to both pathological and reparative processes. While the alternative, anti-inflammatory (M2) phenotype is believed to promote cell protection, regeneration, and plasticity, pro-inflammatory (M1) macrophages persist after SCI and contribute to protracted cell and tissue loss. Thus, identifying non-invasive, clinically viable, pharmacological therapies for altering macrophage phenotype is a challenging, yet promising, approach for treating SCI. Azithromycin (AZM), a commonly used macrolide antibiotic, drives anti-inflammatory macrophage activation in rodent models of inflammation and in humans with cystic fibrosis.

METHODS: We hypothesized that AZM treatment can alter …

Markey Cancer Center Faculty Publications

Exposure to crystalline silica is suggested to increase the risk for a variety of lung diseases, including fibrosis and lung cancer. However, epidemiological evidences for the exposure-risk relationship are ambiguous and conflicting, and experimental study from a reliable animal model to explore the relationship is lacking. We reasoned that a mouse model that is sensitive to both lung injury and tumorigenesis would be appropriate to evaluate the exposure-risk relationship. Previously, we showed that, Gprc5a-/- mice are susceptible to both lung tumorigenesis and endotoxin-induced acute lung injury. In this study, we investigated the biological consequences in Gprc5a-/- mouse model …

A Combination Approach To Treating Fungal Infections, Sanjib K. Shrestha, Marina Y. Fosso, Sylvie Garneau-Tsodikova

Pharmaceutical Sciences Faculty Publications

Azoles are antifungal drugs used to treat fungal infections such as candidiasis in humans. Their extensive use has led to the emergence of drug resistance, complicating antifungal therapy for yeast infections in critically ill patients. Combination therapy has become popular in clinical practice as a potential strategy to fight resistant fungal isolates. Recently, amphiphilic tobramycin analogues, C12 and C14, were shown to display antifungal activities. Herein, the antifungal synergy of C12 and C14 with four azoles, fluconazole (FLC), itraconazole (ITC), posaconazole (POS), and voriconazole (VOR), was examined against seven Candida albicans strains. All tested strains …

Reduced Voluntary Running Performance Is Associated With Impaired Coordination As A Result Of Muscle Satellite Cell Depletion In Adult Mice, Janna R. Jackson, Tyler J. Kirby, Christopher S. Fry, Robin L. Cooper, John J. Mccarthy, Charlotte A. Peterson, Esther E. Dupont-Versteegden

Physical Therapy Faculty Publications

BACKGROUND: Satellite cells, or muscle stem cells, have been thought to be responsible for all muscle plasticity, but recent studies using genetically modified mouse models that allow for the conditional ablation of satellite cells have challenged this dogma. Results have confirmed the absolute requirement of satellite cells for muscle regeneration but surprisingly also showed that they are not required for adult muscle growth. While the function of satellite cells in muscle growth and regeneration is becoming better defined, their role in the response to aerobic activity remains largely unexplored. The purpose of the current study was to assess the …

Mice Deficient In Endothelial Α5 Integrin Are Profoundly Resistant To Experimental Ischemic Stroke, Jill Roberts, Leon De Hoog, Gregory J. Bix

Sanders-Brown Center on Aging Faculty Publications

Stroke is a disease in dire need of better therapies. We have previously shown that a fragment of the extracellular matrix proteoglycan, perlecan, has beneficial effects following cerebral ischemia via the α5β1 integrin receptor. We now report that endothelial cell selective α5 integrin deficient mice (α5 KO) are profoundly resistant to ischemic infarct after transient middle cerebral artery occlusion. Specifically, α5 KOs had little to no infarct 2–3 days post-stroke, whereas controls had an increase in mean infarct volume over the same time period as expected. Functional outcome is also improved in the α5 KOs compared with controls. Importantly, no …

Low-Dose Vitamin K Can Improve Warfarin Control In Patients On Lvad Support, Daizo Tanaka, Venessa L. Kotch, Cheryl Abbas, Gordon Reeves, John Wc Entwistle Iii

The VAD Journal

Background

Anticoagulation with oral vitamin K antagonists (VKA) is very important in patients supported on a left ventricular assist device (LVAD) to prevent thromboembolic complications. Some patients tolerate VKAs poorly and have an unstable INR as a result. It is reported that low-dose vitamin K can improve INR control in patients with an unstable INR in other clinical settings. We evaluated its safety and effectiveness in patients on LVAD support.

Methods

The records of all patients supported on an implantable LVAD between January, 2013 and March, 2014 were reviewed retrospectively to identify those who had received low-dose vitamin K while …

A Cytosolic Multiprotein Complex Containing P85Α Is Required For Β-Catenin Activation In Colitis And Colitis-Associated Cancer, Tatiana Goretsky, Emily M. Bradford, Hyunji Ryu, Maryam Tahir, Mary Pat Moyer, Tianyan Gao, Linheng Li, Terrence A. Barrett

Internal Medicine Faculty Publications

Wnt/β-catenin signaling is required for crypt structure maintenance. We previously observed nuclear accumulation of Ser-552 phosphorylated β-catenin (pβ-CatSer-552) in intestinal epithelial cells (IEC) during colitis and colitis-associated cancer. Data here delineate a novel multiprotein cytosolic complex (MCC) involved in β-catenin signaling in the intestine. The MCC contains p85α, the class IA subunit of PI3K, along with β-catenin, 14-3-3ζ, Akt, and p110α. MCC levels in IEC increase in colitis and colitis-associated cancer patients. IEC-specific p85α-deficient (p85ΔIEC) mice develop more severe dextran sodium …

Center for Research on Environmental Disease Faculty Publications

Arsenic (As3+) is a carcinogen with considerable environmental and occupational relevancy. The present study shows that As3+-transformed human lung bronchial epithelial BEAS-2B cells (AsT cells) exhibit the property of apoptosis resistance. The level of basal reactive oxygen species (ROS) is very low in AsT cells in correlation with elevated expressions of both antioxidant enzymes and antiapoptotic proteins. Nuclear factor erythroid 2-related factor (Nrf2) and p62 are constitutively expressed. These two proteins up-regulate antioxidant enzymes and antiapoptotic proteins. The knockdown of Nrf2 or p62 by small interfering RNA (siRNA) enhanced both ROS levels and As3+-induced …

Integrin Α6Β4 Promotes Autocrine Epidermal Growth Factor Receptor (Egfr) Signaling To Stimulate Migration And Invasion Toward Hepatocyte Growth Factor (Hgf), Brittany L. Carpenter, Min Chen, Teresa Knifley, Kelley A. Davis, Susan M.W. Harrison, Rachel L. Stewart, Kathleen O'Connor

Markey Cancer Center Faculty Publications

Integrin α6β4 is up-regulated in pancreatic adenocarcinomas where it contributes to carcinoma cell invasion by altering the transcriptome. In this study, we found that integrin α6β4 up-regulates several genes in the epidermal growth factor receptor (EGFR) pathway, including amphiregulin (AREG), epiregulin (EREG), and ectodomain cleavage protease MMP1, which is mediated by promoter demethylation and NFAT5. The correlation of these genes with integrin α6β4 was confirmed in The Cancer Genome Atlas Pancreatic Cancer Database. Based on previous observations that integrin α6β4 cooperates with c-Met in pancreatic cancers, we examined the impact of EGFR signaling on hepatocyte growth factor (HGF)-stimulated migration and …

Deletion Of Aquaporin-4 In App/Ps1 Mice Exacerbates Brain Aβ Accumulation And Memory Deficits, Zhiqiang Xu, Na Xiao, Yali Chen, Huang Huang, Charles Marshall, Junying Gao, Zhiyou Cai, Ting Wu, Gang Hu, Ming Xiao

Center of Excellence in Rural Health Faculty Publications

BACKGROUND: Preventing or reducing amyloid-beta (Aβ) accumulation in the brain is an important therapeutic strategy for Alzheimer's disease (AD). Recent studies showed that the water channel aquaporin-4 (AQP4) mediates soluble Aβ clearance from the brain parenchyma along the paravascular pathway. However the direct evidence for roles of AQP4 in the pathophysiology of AD remains absent.

RESULTS: Here, we reported that the deletion of AQP4 exacerbated cognitive deficits of 12-moth old APP/PS1 mice, with increases in Aβ accumulation, cerebral amyloid angiopathy and loss of synaptic protein and brain-derived neurotrophic factor in the hippocampus and cortex. Furthermore, AQP4 deficiency increased …
