Journal of Medicine in Scientific Research

Introduction Hearing is the principal sensory modality by which language and speech are acquired. For that reason, a child with hearing loss whose family chooses an auditory approach for learning language must have as much exposure to high-quality auditory stimulation as possible. Both hearing aids and cochlear implants (CI) are best in quiet and close places, but not so good at a distance, in noise or when sounds bounce around. Children with CI have significant difficulty in hearing conversational speech in the presence of background noise. They may have difficulty understanding soft speech signals due to distance and reverberation. Assistive …

Trypanosoma Brucei Prmt1 Is A Nucleic Acid Binding Protein With A Role In Energy Metabolism And The Starvation Stress Response., Lucie Kafková, Chengjian Tu, Kyle L. Pazzo, Kyle P. Smith, Erik W. Debler, Kimberly S. Paul, Jun Qu, Laurie K. Read

Department of Biochemistry and Molecular Biology Faculty Papers

In Trypanosoma brucei and related kinetoplastid parasites, transcription of protein coding genes is largely unregulated. Rather, mRNA binding proteins, which impact processes such as transcript stability and translation efficiency, are the predominant regulators of gene expression. Arginine methylation is a posttranslational modification that preferentially targets RNA binding proteins and is, therefore, likely to have a substantial impact on T. brucei biology. The data presented here demonstrate that cells depleted of T. brucei PRMT1 (TbPRMT1), a major type I protein arginine methyltransferase, exhibit decreased virulence in an animal model. To understand the basis of this phenotype, quantitative global proteomics was employed …

Als Mutations Of Fus Suppress Protein Translation And Disrupt The Regulation Of Nonsense-Mediated Decay, Marisa Kamelgarn, Jing Chen, Lisha Kuang, Huan Jin, Edward J. Kasarskis, Haining Zhu

Toxicology and Cancer Biology Faculty Publications

Amyotrophic lateral sclerosis (ALS) is an incurable neurodegenerative disease characterized by preferential motor neuron death. Approximately 15% of ALS cases are familial, and mutations in the fused in sarcoma (FUS) gene contribute to a subset of familial ALS cases. FUS is a multifunctional protein participating in many RNA metabolism pathways. ALS-linked mutations cause a liquid–liquid phase separation of FUS protein in vitro, inducing the formation of cytoplasmic granules and inclusions. However, it remains elusive what other proteins are sequestered into the inclusions and how such a process leads to neuronal dysfunction and degeneration. In this study, we developed …

The Effects Of Inhibiting Pi3k On Tumor Suppressor Gene P53 And Cell Proliferation, Kelsi Peters

Undergraduate Theses and Capstone Projects

When the cell surface molecule, Human EGF Receptor (HER2), is overexpressed, the cell can become cancerous. MDA-MB-453 is an established breast cancer cell line made cancerous by HER2 overexpression. This mutation that causes HER2 overexpression affects the cell signaling pathway of phosphoinositide 3-kinase (PI₃K), Akt, MDM2, and p53. We predicted that PI₃K would be inhibited with the compound, LY294002, sending signals for Akt and MDM2 to be deactivated in MDA-MB-453 cells. Deactivated MDM2 signals for p53 to be activated. P53 is a tumor suppressor protein that exists in low quantities in normal cells, but when damage …

Sequence-Specific Extracellular Micrornas Activate Tlr7, Niming Wu

Theses & Dissertations

Toll-like receptors (TLRs) play an important role in the innate immune system. Emerging evidence shows that TLRs, especially endosomal TLRs, can participate in CNS diseases by increasing the production of proinflammatory cytokines via recognition of microRNAs (miRNAs), however which of the miRNAs are able to activate signaling and whether specific sequence motifs are involved remains incompletely defined. Here we found that numerous miRNAs induced TNF-a production across multiple myeloid cell types, including microglia, and that this effect was abolished in cells deficient of TLR7. In particular, miR-20a-5p and miR-148b-3p preferentially stimulate cytokine secretion compared to miR-20b-5p and miR-148a-3p, respectively, despite …

Dietary Polyunsaturated Fatty Acids Regulate Mammary Tumor Growth And Metastasis By Modulating Tissue Microenvironments, Saraswoti Khadge

Theses & Dissertations

Omega (ω)-6 and ω-3 polyunsaturated fatty acids (PUFAs) are essential fatty acids (FAs) and the precursors of pro- and anti-inflammatory mediators respectively. Epidemiological studies have shown a lower incidence of breast cancer (BC) in the countries where long-chain (LC)-ω-3FAs consumption is higher; however, the role of ω-3FAs in BC growth and metastasis is poorly understood. We used isocaloric, isolipidic ω-6 and ω-3 (contains LC-ω-3FAs) diets and a pair-fed model to evaluate the effects of dietary PUFAs in mammary tumor metastasis. Our studies have resulted in several novel observations including that dietary LC-ω-3FAs modulate mammary gland (MG) microenvironments in non-tumor bearing …

Manganese-Enhanced Magnetic Resonance Imaging: Overview And Central Nervous System Applications With A Focus On Neurodegeneration, Ryan A. Cloyd, Shon A. Koren, Jose F. Abisambra

Physiology Faculty Publications

Manganese-enhanced magnetic resonance imaging (MEMRI) rose to prominence in the 1990s as a sensitive approach to high contrast imaging. Following the discovery of manganese conductance through calcium-permeable channels, MEMRI applications expanded to include functional imaging in the central nervous system (CNS) and other body systems. MEMRI has since been employed in the investigation of physiology in many animal models and in humans. Here, we review historical perspectives that follow the evolution of applied MRI research into MEMRI with particular focus on its potential toxicity. Furthermore, we discuss the more current in vivo investigative uses of MEMRI in CNS investigations and …

Wallace, Megerditch Kiledjian, Dmitry Temiakov, Smita S. Patel, Richard H. Ebright, Bryce E. Nickels

Department of Biochemistry and Molecular Biology Faculty Papers

Bacterial and eukaryotic nuclear RNA polymerases (RNAPs) cap RNA with the oxidized and reduced forms of the metabolic effector nicotinamide adenine dinucleotide, NAD+ and NADH, using NAD+ and NADH as non-canonical initiating nucleotides for transcription initiation. Here, we show that mitochondrial RNAPs (mtRNAPs) cap RNA with NAD+ and NADH, and do so more efficiently than nuclear RNAPs. Direct quantitation of NAD+- and NADH-capped RNA demonstrates remarkably high levels of capping in vivo: up to ~60% NAD+ and NADH capping of yeast mitochondrial transcripts, and up to ~15% NAD+ capping of human mitochondrial transcripts. The capping efficiency is determined by promoter …

Subject Level Clustering Using A Negative Binomial Model For Small Transcriptomic Studies., Qian Li, Janelle R. Noel-Macdonnell, Devin C. Koestler, Ellen L. Goode, Brooke L. Fridley

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Unsupervised clustering represents one of the most widely applied methods in analysis of high-throughput 'omics data. A variety of unsupervised model-based or parametric clustering methods and non-parametric clustering methods have been proposed for RNA-seq count data, most of which perform well for large samples, e.g. N ≥ 500. A common issue when analyzing limited samples of RNA-seq count data is that the data follows an over-dispersed distribution, and thus a Negative Binomial likelihood model is often used. Thus, we have developed a Negative Binomial model-based (NBMB) clustering approach for application to RNA-seq studies.

RESULTS: We have developed a Negative …

Global Connectivity And Function Of Descending Spinal Input Revealed By 3d Microscopy And Retrograde Transduction, Zimei Wang, Brian Maunze, Yunfang Wang, Pantelis Tsoulfas, Murray G. Blackmore

Biomedical Sciences Faculty Research and Publications

The brain communicates with the spinal cord through numerous axon tracts that arise from discrete nuclei, transmit distinct functions, and often collateralize to facilitate the coordination of descending commands. This complexity presents a major challenge to interpreting functional outcomes from therapies that target supraspinal connectivity after injury or disease, while the wide distribution of supraspinal nuclei complicates the delivery of therapeutics. Here we harness retrograde viral vectors to overcome these challenges. We demonstrate that injection of AAV2-Retro to the cervical spinal cord of adult female mice results in highly efficient transduction of supraspinal populations throughout the brainstem, midbrain, and cortex. …
