Exposure to hydrochloric acid (HCl) can provoke acute and chronic lung injury. Because of its extensive production for industrial use, frequent accidental exposures occur, making HCl one of the top five chemicals causing inhalation injuries. There are no Food and Drug Administration (FDA)-approved treatments for HCl exposure. Heat shock protein 90 (HSP90) inhibitors modulate transforming growth factor-β (TGF-β) signaling and the development of chemical-induced pulmonary fibrosis. However, little is known on the role of Heat Shock Protein 70 (HSP70) during injury and treatment with HSP90 inhibitors. We hypothesized that administration of geranylgeranyl-acetone (GGA), an HSP70 inducer, or gefitinib (GFT), an …

Association Of Inflammatory Markers And Growth Factors With Radiographically Assessed Wound Healing Of Extraction Sockets, Sasha Mohammadi
Theses & Dissertations
The purpose of this prospective cohort pilot study was to investigate the association of the periodontal status and inflammatory markers from the gingival crevicular and wound fluid with the healing outcomes following tooth extraction. The central research hypothesis is that extraction sites and the adjacent teeth that exhibit increased markers of inflammation, or decreased growth factors, at baseline or 2 weeks will be associated with reduced healing outcomes observed radiographically 3 months following surgery. Nine patients at the UNMC College of Dentistry who were seeking care to extract a posterior tooth due to advanced periodontal bone loss, non-restorable caries or …

About 99% of the global population resides in areas with air pollution surpassing World Health Organization standards. Air pollution is associated with adverse neonatal health outcomes such as low fetal birth weight and an increased risk for maternal pre-eclampsia. A particularly reactive air pollutant is ozone, which forms reactive oxygen species that induce cellular damage. Research exists on the dispersion of reactive oxygen species through the bloodstream leading to fetal vulnerability during pregnancy, specifically via the placenta. Yet, placental and fetal development is a temporal process with varied susceptibility to negative gestational outcomes.
To addressing this gap, our laboratory utilized …

Hematology/Oncology and Stem Cell Therapy
The most common and aggressive brain tumor in the adult population is glioblastoma (GBM). The lifespan of patients does not exceed 22 months. One of the reasons for the low effectiveness of GBM treatment is its radioresistance and chemoresistance. In the current review, we discuss the phenomenon of multidrug resistance of GBM in the context of the expression of ABC family transporter proteins and the mechanisms of proliferation, angiogenesis, and recurrence. We focused on the search of molecular targets among growth factors, receptors, signal transduction proteins, microRNAs, transcription factors, proto-oncogenes, tumor suppressor genes, and their single-nucleotide polymorphisms.

Cytokines In The Pathogenesis Of Large Granular Lymphocytic Leukemia, Colleen Isabelle, Amy Boles, Nitin Chakravarti, Pierluigi Porcu, Jonathan Brammer, Anjali Mishra
Department of Medical Oncology Faculty Papers
Large granular lymphocytic leukemia (LGLL) is a lymphoproliferative disorder of older adults characterized by the clonal expansion of cytotoxic T/natural killer cells due to constitutive pro-survival signaling. In recent years, it has become clear that cytokines and their receptors are aberrantly expressed in LGLL cells. The exact initiation process of LGLL is unknown, although several cytokine-driven mechanisms have emerged. Elevated levels of several cytokines, including interleukin-15 (IL-15) and platelet-derived growth factor (PDGF), have been described in LGLL patients. Evidence from humans and animal models has shown that cytokines may also contribute to the co-occurrence of a wide range of autoimmune …

Osteoblast And Osteoclast Bioactivity Responses To Growth Factors And Inhibitors, Dana Walid Al Hashimi
Osteoblast And Osteoclast Bioactivity Responses To Growth Factors And Inhibitors, Dana Walid Al Hashimi
Student Theses, Dissertations and Capstones
Bone healing, regeneration, maintenance, and bone defect repair is dependent on the regenerative capacity of Osteoblasts. Bone resorption, osteoporosis, peri implantitis and bone loss are caused by the activity of Osteoclasts. It is the balance in activity between bone regeneration by Osteoblasts and bone resorption by Osteoclasts which determines if bone regeneration or bone loss occurs. Osteoblast and Osteoclast cells respond to growth factors and bioactive inhibitors within the local environment, and the concentrations of these molecules may help determine if bone loss or bone regeneration occurs. To develop new therapies which can promote bone regeneration and avoid bone resorption: …

Laryngeal dysfunction in the elderly is a major cause of disability, from voice disorders to dysphagia and loss of airway protective reflexes. Few, if any, therapies exist that target age-related laryngeal muscle dysfunction. Neurotrophins are involved in muscle innervation and differentiation of neuromuscular junctions (NMJs). It is thought that neurotrophins enhance neuromuscular transmission by increasing neurotransmitter release. The neuromuscular junctions (NMJs) become smaller and less abundant in aging rat laryngeal muscles, with evidence of functional denervation. We explored the effects of NTF4 for future clinical use as a therapeutic to improve function in aging human laryngeal muscles. Here, we provide …
Short-Term Bilateral Adrenalectomy: Biochemical And Morphological Alterations In The Rat Hippocampus, Ahlam Said Abi Issa
Short-Term Bilateral Adrenalectomy: Biochemical And Morphological Alterations In The Rat Hippocampus, Ahlam Said Abi Issa
Theses
Several studies showed the effects of glucocorticoid hormones on the hippocampus. It has been reported that the chronic administration of high dose glucocorticoids (GC) results in the degeneration of pyramidal neurons. However, bilateral adrenalectomy has been shown to damage the hippocampal neurons. Although the effects of long-term adrenalectomy have been studied extensively, there are few publications on the effects of short-term bilateral adrenalectomy (ADX). We aimed to investigate the effects of ADX on levels of pro-inflammatory cytokines interleukin-1β (IL-1β), interkeukin-6 (IL-6) and tumor necrosis factor-α (TNF-α); levels of growth factors, response of microglia and astrocytes to neuronal death, and oxidative …

Molecular And Cellular Biology Of Prostate Cancer, El-Nasir Lalani, Marc Elie Laniado, Paul David Abel
Molecular And Cellular Biology Of Prostate Cancer, El-Nasir Lalani, Marc Elie Laniado, Paul David Abel
El Nasir Lalani
Prostate cancer is an enigmatic disease. Although prostatic-intraepithelial neoplasia appears as early as the third decade and as many as 80% of 80 year old men have epithelial cells in their prostate that fit the morphological criteria for cancer, only about 10% of men will ever have the clinical disease and less than 3% will die from it. There have been no significant proven interventions which have altered the natural history of the disease since hormone down regulation was introduced in the 1940s and new research has been poorly supported. There is however an urgent need to develop new criteria …

Enhancement Of Aging Rat Laryngeal Muscles With Endogenous Growth Factor Treatment, Joseph C. Stemple, Richard D. Andreatta, Tanya S. Seward, Vrushali Angadi, Maria Dietrich, Colleen A. Mcmullen
Physical Therapy Faculty Publications
Clinical evidence suggests that laryngeal muscle dysfunction is associated with human aging. Studies in animal models have reported morphological changes consistent with denervation in laryngeal muscles with age. Life‐long laryngeal muscle activity relies on cytoskeletal integrity and nerve–muscle communication at the neuromuscular junction (NMJ). It is thought that neurotrophins enhance neuromuscular transmission by increasing neurotransmitter release. We hypothesized that treatment with neurotrophin 4 (NTF4) would modify the morphology and functional innervation of aging rat laryngeal muscles. Fifty‐six Fischer 344xBrown Norway rats (6‐ and 30‐mo age groups) were used to evaluate to determine if NTF4, given systemically (n = 32) …

Dennis, Usha Ponnappan, Ralph L. Kodell, Kimberly K. Garner, Christopher M. Parkes, Melinda M. Bopp, Kalpana P. Padala, Charlotte A. Peterson, Prasad R. Padala, Dennis H. Sullivan
Physical Therapy Faculty Publications
BACKGROUND: Immune function may influence the ability of older adults to maintain or improve muscle mass, strength, and function during aging. Thus, nutritional supplementation that supports the immune system could complement resistance exercise as an intervention for age-associated muscle loss. The current study will determine the relationship between immune function and exercise training outcomes for older adults who consume a nutritional supplement or placebo during resistance training and post-training follow-up. The supplement was chosen due to evidence suggesting its ingredients [arginine (Arg), glutamine (Gln), and β-hydroxy β-methylbutyrate (HMB)] can improve immune function, promote muscle growth, and counteract muscle loss. …

The Transcriptomics To Proteomics Of Hair Cell Regeneration: Looking For A Hair Cell In A Haystack, Gopinath Rajadinakaran
UCHC Articles - Research
Mature mammals exhibit very limited capacity for regeneration of auditory hair cells, while all non-mammalian vertebrates examined can regenerate them. In an effort to find therapeutic targets for deafness and balance disorders, scientists have examined gene expression patterns in auditory tissues under different developmental and experimental conditions. Microarray technology has allowed the large-scale study of gene expression profiles (transcriptomics) at whole-genome levels, but since mRNA expression does not necessarily correlate with protein expression, other methods, such as microRNA analysis and proteomics, are needed to better understand the process of hair cell regeneration. These technologies and some of the results of …

Reconstruction Of Nigrostriatal Pathway In An Animal Model Of Parkinson's Disease, Chen Zhang
Reconstruction Of Nigrostriatal Pathway In An Animal Model Of Parkinson's Disease, Chen Zhang
Theses and Dissertations--Physiology
Parkinson's disease is characterized by progressive degeneration of substantia nigra (SN) and subsequently loss of the nigrostriatal circuit. Many strategies have attempted to reconstruct this circuit but failed to satisfy clinical trials. The inhibitory environment of the adult CNS and the long distance between the SN and the striatum make true reconstruction difficult. To reconstruct this circuit, we used a transplant-pathway targeting model. Several putative pathway targeting molecules were examined for their ability to direct the growth of axons from a dopaminergic transplant. For a proof-of-principle study, adenoviral and lentiviral encoded glial cell line-derived neurotrophic factor (GDNF), GDNF-receptor alpha1 (GFRa1 …
