Background

Chronic Otitis Media with effusion (COME) develops after sustained inflammation and is characterized by secretory middle ear epithelial metaplasia and effusion, most frequently mucoid. Non-typeable Haemophilus influenzae (NTHi), the most common acute Otitis Media (OM) pathogen, is postulated to promote middle ear epithelial remodeling in the progression of OM from acute to chronic. The goals of this study were to examine histopathological and quantitative proteomic epithelial effects of NTHi challenge in a murine middle ear epithelial cell line.

Methods

NTHi lysates were generated and used to stimulate murine epithelial cells (mMEEC) cultured at air-liquid interface over 48 hours– …

The Synergistic Roles Of Cholecystokinin B And Dopamine D5 Receptors On The Regulation Of Renal Sodium Excretion., Xiaoliang Jiang, Wei Chen, Xing Liu, Zihao Wang, Yunpeng Liu, Robin A Felder, John J Gildea, Pedro A. Jose, Chuan Qin, Zhiwei Yang

Medicine Faculty Publications

Renal dopamine D1-like receptors (D1R and D5R) and the gastrin receptor (CCKBR) are involved in the maintenance of sodium homeostasis. The D1R has been found to interact synergistically with CCKBR in renal proximal tubule (RPT) cells to promote natriuresis and diuresis. D5R, which has a higher affinity for dopamine than D1R, has some constitutive activity. Hence, we sought to investigate the interaction between D5R and CCKBR in the regulation of renal sodium excretion. In present study, we found D5R and CCKBR increase each other's expression in a concentration- and time-dependent manner in the HK-2 cell, the specificity of which was …

Cryptorchidism is a male congenital disorder with an unspecified, multifactorial etiology. This review evaluated the strength of select factors in the development of cryptorchidism to better understand its etiology. The strength of relationship between factors and their respective functions during testicular descent was evaluated. Factors evaluated in the causal pathway include the signaling mechanisms Desert Hedgehog (DHH), Insulin-like Hormone 3 (INSL3) and Platelet-Derived Growth Factor (PDGF), as well as sex hormone regulation (androgen: estrogen ratio, aromatase expression). Articles supporting a factor in testicular descent were evaluated and scored. These scores were summed to create the “Step Score” for each step …

Cardiac Consequences Of Selective Adrenergic Cell Ablation In Mice, Lahari Tumuluri

Honors Undergraduate Theses

Phenylethanolamine-N-methyltransferase (Pnmt), is the enzyme that catalyzes the conversion of noradrenaline to adrenaline. It has been found in the embryonic heart and in certain adult heart cells, including intrinsic cardiac adrenergic cells, intracardiac neurons, and cardiomyocytes, but their physiological role in the heart is not well understood. To determine the function of Pnmt-expressing cells in the developing heart, a novel genetically-targeted mouse model that causes selective cellular suicide of Pnmt-expressing cells was created by mating Pnmt-Cre Recombinase knock-in mice (Pnmt^Cre/Cre) with ROSA26-eGFP-DTA (R26R^+/DTA). The “cellular suicide” allele is the Diptheria Toxin A (DTA) gene …

Prenatal Nicotine Exposure As A Teratogen In Neurological Pathways, Monica Grover

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Attention-deficit/hyperactivity disorder (ADHD) is the most heritable and commonly diagnosed childhood psychiatric disorder with 4% of all children being diagnosed with this disorder. Prenatal smoking has been found to be a risk factor for ADHD, a disorder that has been believed to be linked to the fluctuation of dopamine levels. Prenatal nicotine exposure in the second trimester influences dopaminergic neurological pathways by altering dopamine release levels. The altered dopamine levels make the fetus brain more sensitive to the nicotine, causing the nicotine exposure to be more dangerous in causing ADHD symptoms. Prenatal nicotine exposure alters the neurological pathway of the …

Loss of plasticity‐related gene 1 (PRG‐1), which regulates synaptic phospholipid signaling, leads to hyperexcitability via increased glutamate release altering excitation/inhibition (E/I) balance in cortical networks. A recently reported SNP in prg‐1 (R345T/mutPRG‐1) affects ~5 million European and US citizens in a monoallelic variant. Our studies show that this mutation leads to a loss‐of‐PRG‐1 function at the synapse due to its inability to control lysophosphatidic acid (LPA) levels via a cellular uptake mechanism which appears to depend on proper glycosylation altered by this SNP. PRG‐1^+/− mice, which are animal correlates of human PRG‐1^+/mut carriers, showed an altered cortical network …

Microbiome-Gut-Brain Axis: A Pathway For Improving Brainstem Serotonin Homeostasis And Successful Autoresuscitation In Sids-A Novel Hypothesis., Vijayakumar Praveen, Shama Praveen

Articles, Abstracts, and Reports

Sudden infant death syndrome (SIDS) continues to be a major public health issue. Following its major decline since the "Back to Sleep" campaign, the incidence of SIDS has plateaued, with an annual incidence of about 1,500 SIDS-related deaths in the United States and thousands more throughout the world. The etiology of SIDS, the major cause of postneonatal mortality in the western world, is still poorly understood. Although sleeping in prone position is a major risk factor, SIDS continues to occur even in the supine sleeping position. The triple-risk model of Filiano and Kinney emphasizes the interaction between a susceptible infant …

Randomized, Placebo-Controlled Trial Evaluating The Safety Of One-Year Administration Of Green Tea Catechins, Nagi B. Kumar, Julio Pow-Sang, Philippe E. Spiess, Jong Park, Raoul Salup, Christopher R. Williams, Howard Parnes, Michael J. Schell

Urology Faculty Publications

Purpose: Although preclinical, epidemiological and prior clinical trial data suggest that green tea catechins (GTCs) may reduce prostate cancer (PCa) risk, several preclinical studies and case reports have reported liver toxicities and acute gastrointestinal bleeding. Based on these observations, regulatory bodies have required stringent inclusion criteria with frequent, excessive toxicity monitoring and early stopping rules in clinical trials. These requirements have impeded recruitment and retention of subjects in chemoprevention trials and subsequent progress in agent development efforts.

Experimental Design: We conducted a placebo-controlled, randomized clinical trial of Polyphenon E® (PolyE®), a proprietary mixture of decaffeinated GTCs, containing 400 mg (−)-epigallocatechin-3-gallate …

Mucosal Vaccination By Adenoviruses Displaying Reovirus Sigma 1, Eric A. Weaver, Zenaido T. Camacho, Matthew L. Hillestad, Catherine M. Crosby, Mallory A. Turner, Adam J. Guenzel, Hind J. Fadel, George T. Mercier, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

We previously developed adenovirus serotype 5 (Ad5) vectors displaying the sigma 1 protein from reovirus as mucosal vaccines. Ad5-sigma retargets to JAM-1 and sialic acid, but had 40-fold reduced gene delivery when compared to Ad5. While weaker at transduction, Ad5-sigma generated stronger T cell responses than Ad5 when used for mucosal immunization. New Ad5- fiber-sigma vectors were generated here by varying the number of fiber β-spiral shaft repeats (R) fused between fiber tail and the sigma. Ad5 virions encoding R3, R14, and R20 chimeras were rescued. Increasing chimera length led to their decreasing encapsidation of these proteins in the virions. …

Effect Of Twisted Fiber Anisotropy In Cardiac Tissue On Ablation With Pulsed Electric Fields, Fei Xie, Christian W. Zemlin

Bioelectrics Publications

Background: Ablation of cardiac tissue with pulsed electric fields is a promising alternative to current thermal ablation methods, and it critically depends on the electric field distribution in the heart.

Methods: We developed a model that incorporates the twisted anisotropy of cardiac tissue and computed the electric field distribution in the tissue. We also performed experiments in rabbit ventricles to validate our model. We find that the model agrees well with the experimentally determined ablation volume if we assume that all tissue that is exposed to a field greater than 3 kV/cm is ablated. In our numerical analysis, we considered …

Pharmacological Inhibition Of Cyclophilin Ameliorates Experimental Allergic Encephalomyelitis, Zi L. Huang

Theses and Dissertations

A subset of cyclophilins have been implicated in mechanisms of neuroinflammation and neurodegeneration that contributes to the pathogenesis of Multiple Sclerosis. Mitochondrial dysfunction leading to mitochondrial permeability transition plays a pivotal role in axonal damage and disease progression in Multiple Sclerosis. Cyclophilin D (CypD) is a crucial regulatory component of the mitochondrial permeability transition pore and it was demonstrated that the cyclophilin D knockout animals showed reduced experimental allergic encephalomyelitis (EAE) clinical disease severity and axonal injury. We investigated the effect of N-methyl-4-isoleucine-cyclosporin (NIM811), a non-immunosuppressive and non-selective cyclophilin inhibitor, on the course and severity of EAE. EAE mice treated …

Molecular Mechanisms Of Suberoylanilide Hydroxamic Acid In The Inhibition Of Tgf-Β1-Mediated Canine Corneal Fibrosis, Kristina M. Gronkiewicz, Elizabeth A. Giuliano, Ajay Sharma, Rajiv R. Mohan

Pharmacy Faculty Articles and Research

Objective—To investigate molecular mechanisms mediating anti-fibrotic effect of SAHA in the canine cornea using an in vitro model. We hypothesized that SAHA attenuates corneal fibrosis by modulating Smad-dependent and, to a lesser extent, Smad-independent signaling pathways activated by TGF-β1, as well as matrix metalloproteinase (MMP) activity.

Methods—Cultured canine corneal fibroblasts (CCF) were incubated in the presence/absence of TGF-β1 (5ng/ml) and SAHA (2.5μM) for 24hrs. Western blot analysis was used to quantify non-phosphorylated and phosphorylated isoforms of Smad2/3, p38 MAP kinase (MAPK), ERK1/2 and JNK1. Real-time PCR and zymography were utilized to quantify MMP1, MMP2, MMP8 and MMP9 mRNA expression and …

The Role Of Capillaries In The Lesser Ailments Of Old Age And In Alzheimer's Disease And Vascular Dementia: The Potential Of Pro-Therapeutic Angiogenesis, Charles T. Ambrose

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Apart from chronic diseases (arthritis, diabetes, etc.), old age is generally characterized by three lesser ailments: muscle weakness, minor memory lapses, and cold intolerance. This trio of complaints may have a common, underlying cause, namely, the age-associated reduced microcirculation in muscles, brain, skin, and elsewhere in the body. The Angiogenesis Hypothesis proposes that old age is in part a deficiency disease due to the decline in angiogenic (AG) factors, resulting in a reduced capillary density (CD) throughout the body. Over fifty published papers document waning levels of AG factors and/or decreased CD in various organ systems of aged animals and …

Recapitulating Cross-Species Transmission Of Sivcpz To Humans Using Humanized-Blt Mice, Zhe Yuan, Guobin Kang, Fangrui Ma, Wuxun Lu, Wenjin Fan, Christine M. Fennessey, Brandon F. Keele, Qingsheng Li

Nebraska Center for Virology: Faculty Publications

The origins of HIV-1 have been widely accepted to be the consequence of simian immunodeficiency viruses from wild chimpanzees (SIVcpz) crossing over to humans. However, there has not been any in vivo study of SIVcpz infection of humans. Also, it remains largely unknown why only specific SIVcpz strains have achieved cross-species transmission and what transmission risk might exist for those SIVcpz strains that have not been found to infect humans. Closing this knowledge gap is essential for better understanding cross-species transmission and predicting the likelihood of additional cross-species transmissions of SIV into humans. Here we show hu-BLT mice are susceptible …
