Detoxification Of Mitochondrial Oxidants And Apoptotic Signaling Are Facilitated By Thioredoxin-2 And Peroxiredoxin-3 During Hyperoxic Injury, Benjamin J. Forred, Darwin R. Daugaard, Brianna K. Titus, Ryan R. Wood, Miranda J. Floen, Michelle L. Booze, Peter F. Vitiello

School of Veterinary and Biomedical Sciences: Faculty Publications

Mitochondria play a fundamental role in the regulation of cell death during accumulation of oxidants. High concentrations of atmospheric oxygen (hyperoxia), used clinically to treat tissue hypoxia in premature newborns, is known to elicit oxidative stress and mitochondrial injury to pulmonary epithelial cells. A consequence of oxidative stress in mitochondria is the accumulation of peroxides which are detoxified by the dedicated mitochondrial thioredoxin system. This system is comprised of the oxidoreductase activities of peroxiredoxin-3 (Prx3), thioredoxin-2 (Trx2), and thioredoxin reductase-2 (TrxR2). The goal of this study was to understand the role of the mitochondrial thioredoxin system and mitochondrial injuries during …

Maternal Inflammation At Mid-Gestation In Pregnant Rats Impairs Fetal Muscle Growth And Development At Term, C. N. Cadaret, K. A. Beede, E. M. Merrick, T. L. Barnes, J. D. Loy, D. T. Yates

School of Veterinary and Biomedical Sciences: Faculty Publications

Intrauterine growth restriction (IUGR) is a leading cause of perinatal morbidity and mortality. Low birth weight resulting from preterm birth and/or IUGR is an underlying factor in 60–80% of perinatal death worldwide, and is particularly common in developing countries (UNICEF, 2008). Furthermore, studies have linked IUGR and the associated fetal malnutrition to increased incidence of metabolic syndrome in adult life (Barker et al., 1993; Godfrey and Barker, 2000). The “thrifty phenotype hypothesis” developed by David Barker (Hales et al., 1991) states that IUGR-associated fetal malnutrition forces the fetus to spare nutrients by altering tissue-specific metabolism in order to survive. In …

A Parapoxviral Virion Protein Targets The Retinoblastoma Protein To Inhibit Nf-Κb Signaling, Ponnuraj Nagendraprabhu, Sushil Khatiwada, Sabal Chaulagain, Gustavo A. Delhon, Daniel L. Rock

School of Veterinary and Biomedical Sciences: Faculty Publications

Poxviruses have evolved multiple strategies to subvert signaling by Nuclear Factor κB (NF-κB), a crucial regulator of host innate immune responses. Here, we describe an orf virus (ORFV) virion-associated protein, ORFV119, which inhibits NF-κB signaling very early in infection (≤30 min post infection). ORFV119 NF-κB inhibitory activity was found unimpaired upon translation inhibition, suggesting that virion ORFV119 alone is responsible for early interference in signaling. A C-terminal LxCxE motif in ORFV119 enabled the protein to interact with the retinoblastoma protein (pRb) a multifunctional protein best known for its tumor suppressor activity. Notably, experiments using a recombinant virus containing an ORFV119 …

Nebraska Center for Virology: Faculty Publications

A previous report indicated that prototype chlorovirus PBCV-1 replicated in two Chlorella variabilis algal strains, NC64A and Syngen 2-3, that are ex-endosymbionts isolated from the protozoan Paramecium bursaria. Surprisingly, plaque-forming viruses on Syngen 2-3 lawns were often higher than on NC64A lawns from indigenous water samples. These differences led to the discovery of viruses that exclusively replicate in Syngen 2-3 cells, named Only Syngen (OSy) viruses. OSy-NE5, the prototype virus for the proposed new species, had a linear dsDNA genome of 327 kb with 44-nucleotide-long, incompletely base-paired, covalently closed hairpin ends. Each hairpin structure was followed by an identical …

Wheezing, Asthma, And Atopy In Premature Infants At 2 Years Of Age, Sevi̇m Ünal, Ayşenur Kaya, Leyla Bi̇lgi̇n, Emi̇ne Di̇bek Misirlioğlu, Can Naci̇ Kocabaş

Turkish Journal of Medical Sciences

Background/aim: We aimed to evaluate wheezing, bronchial asthma (BA), and atopy in premature infants at 2 years of age via a crosssectional study. Materials and methods: Premature infants at <37 weeks of gestational age (GA) were assessed for atopy by skin-prick test and serum immunoglobulin E level at 2 years of age. The family's and infant's histories of allergy, BA, atopy, and wheezing were obtained by questionnaire and from hospital records. Results: There were 98 infants, with mean birth weight (BW) 1517.4 ± 486.5 g and GA 30.8 ± 2.9 weeks. The frequencies of wheezing, asthma, and bronchopulmonary dysplasia (BPD) were 32.7%, 16.3%, and 14.3%, respectively. Skin-prick tests were positive for 11 subjects, with allergy to cereals for 7 infants, egg for 3, and peanut for 1. Wheezing was related to GA, BW, respiratory distress syndrome, mechanical ventilation, sepsis, asphyxia, smoking, antenatal steroid, BA, palivizumab prophylaxis, number of people in the household, and duration of hospitalization (P < 0.05). Wheezing was negatively correlated to GA. Family history of BA, smoking, and number of people in the household were linked to BA (P < 0.05). Conclusion: Wheezing was related to degree of premature birth, but BA was linked to BA in the family and smoking. Increased gestation should improve the infant's respiratory health up to 2 years of age.

Cytolytic Toxin Production By Staphylococcus Aureus Is Dependent Upon The Activity Of The Protoheme Ix Farnesyltransferase, Emily Stevens, Maisem Laabei, Stewart Gardner, Greg A. Somerville, Ruth C. Massey

School of Veterinary and Biomedical Sciences: Faculty Publications

Staphylococcus aureus is a medically important pathogen with an abundance of virulence factors that are necessary for survival within a host, including the production of cytolytic toxins. The regulation of toxin production is mediated by the Agr quorum sensing system, and a poorly defined post-exponential growth phase signal independent of Agr. As part of a recent genome wide association study (GWAS) to identify novel loci that alter the expression of cytolytic toxins, a polymorphism in the cyoE gene, which encodes a protoheme IX farnesyltransferase, was identified. This enzyme is essential for processing heme into the electron transport chain for use …

Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts

Williams Honors College, Honors Research Projects

Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.

Objectives: To evaluate the use of biomarkers in children seen in the Emergency …

Micrornas Modulate Pathogenesis Resulting From Chlamydial Infection In Mice, Laxmi Yeruva, S. Pouncey, Michael R. Eledge, Sudeepa Bhattacharya, Chunqiao Luo, Erin W. Weatherford, David M. Ojcius, Roger G. Rank

All Dugoni School of Dentistry Faculty Articles

Not all women infected with chlamydiae develop upper genital tract disease, but the reason(s) for this remains undefined. Host genetics and hormonal changes associated with the menstrual cycle are possible explanations for variable infection outcomes. It is also possible that disease severity depends on the virulence of the chlamydial inoculum. It is likely that the inoculum contains multiple genetic variants, differing in virulence. If the virulent variants dominate, then the individual is more likely to develop severe disease. Based on our previous studies, we hypothesized that the relative degree of virulence of a chlamydial population dictates the microRNA (miRNA) expression …

School of Veterinary and Biomedical Sciences: Faculty Publications

Introduction: Organ-specific autoimmune diseases are believed to result from immune responses generated against self-antigens specific to each organ. However, when such responses target antigens expressed promiscuously in multiple tissues, then the immune-mediated damage may be wide spread.

Methods: In this report, we describe a mitochondrial protein, branched chain α-ketoacid dehydrogenase kinase (BCKD_k) that can act as a target autoantigen in the development of autoimmune inflammatory reactions in both heart and liver.

Results: We demonstrate that BCKD_k protein contains at least nine immunodominant epitopes, three of which, BCKD_k 71–90, BCKD_k 111–130 and BCKD_k 141–160, …
