Phage Peptide Technology To Characterize Extracellular Vesicles In The Brain Tumors, Jadelynn Rudolf

Undergraduate Research Conference

Extracellular vesicles (EV) are lipid-bound containers derived from the endosomal membrane network or from the extracellular membrane of cells. They can carry proteins, lipids, miRNAs, and other molecules, and may be involved in intercellular communication via membrane-associated proteins. Glioblastomas (GBM) are aggressive cancers of the brain and spinal cord derived from astrocytes. Extracellular vesicles derived from glioblastomas can make their way through the blood brain barrier and find their way to different bodily fluids, and so could serve as biomarkers for this cancer. We have isolated phage-display peptides from a commercial library of random phage-displayed peptides that will bind glioblastoma …

Rna Sequencing In Hypoxia-Adapted T98g Glioblastoma Cells Provides Supportive Evidence For Ire1 As A Potential Therapeutic Target., Brian E White, Yichuan Liu, Hakon Hakonarson, Russell Buono

Cooper Medical School of Rowan University Departmental Research

Glioblastoma (GBM) is an aggressive brain cancer with a median survival time of 14.6 months after diagnosis. GBM cells have altered metabolism and exhibit the Warburg effect, preferentially producing lactate under aerobic conditions. After standard-of-care treatment for GBM, there is an almost 100% recurrence rate. Hypoxia-adapted, treatment-resistant GBM stem-like cells are thought to drive this high recurrence rate. We used human T98G GBM cells as a model to identify differential gene expression induced by hypoxia and to search for potential therapeutic targets of hypoxia adapted GBM cells. RNA sequencing (RNAseq) and bioinformatics were used to identify differentially expressed genes (DEGs) …

Sensitisasi Alergen Makanan Pada Pasien Kolitis Eosinofilik: Laporan Kasus, Agnes Dina Irene Dorithy Zagoto, Deshinta Putri Mulya, Neneng Ratnasari

Jurnal Penyakit Dalam Indonesia

Eosinophilic colitis is a very rare disease that can occur in the bimodal population (neonates and young adults) with a prevalence was 2.1/100,000 in overall population and 2.3/100,000 in adults. However, only about 0.1% of cases were diagnosed from biopsy results obtained during colonoscopy. The lack of precise histological criteria for the quantity of eosinophils in the colon mucosa creates a distinct challenge in diagnosing eosinophilic colitis. Eosinophilia in the gastrointestinal tract can be mediated by IgE and non-IgE, but non-IgE tends to be dominant in adults. This report discusses about a case of a 64-year-old male with bloody diarrhea …

Pamam- Cyclodextrin Conjugate Upregulates Brain-Derived Neurotropic Factor In Arpe-19 Cells, Gopika Ashokan

USF Tampa Graduate Theses and Dissertations

Background: Traumatic Brain Injury (TBI) is a major contributor to death and disability due to motorvehicle accidents, sports, physical abuse, and battlefield injuries. The primary insult to the brain leads to inflammation, vascular dysfunction, and oxidative stress in the brain as well as in the eye. This leads to loss of Retinal Ganglion Cells (RGCs) and downregulation of Brain derived Neurotopic Factor (BDNF). BDNF is a neurotrophic factor that binds to Tropomyosin Receptor Kinase B (TrkB) receptor to promote cell growth, survival, and differentiation. Current treatment strategies do not promote neuronal regeneration. Therefore, novel treatments are needed to restore vision …

INTRODUCTION: Standard-of-care systemic chemotherapies for pancreatic ductal adenocarcinoma (PDAC) currently have limited clinical benefits, in addition to causing adverse side effects in many patients. One factor known to contribute to the poor chemotherapy response is the poor drug diffusion into PDAC tumors. Novel treatment methods are therefore drastically needed to improve targeted delivery of treatments. Here, we evaluated the efficacy of the 3DNA® Nanocarrier (3DNA) platform to direct delivery of therapeutics to PDAC tumors in vivo.

MATERIALS AND METHODS: A panel of PDAC cell lines and a patient tissue microarray were screened for established tumor-specific proteins to identify targeting moieties …

Distinct lines of research in both humans and animals point to a specific role of the hippocampus in both spatial and episodic memory function. The discovery of concept cells in the hippocampus and surrounding medial temporal lobe (MTL) regions suggests that the MTL maps physical and semantic spaces with a similar neural architecture. Here, we studied the emergence of such maps using MTL microwire recordings from 20 patients (9 female, 11 male) navigating a virtual environment featuring salient landmarks with established semantic meaning. We present several key findings. The array of local field potentials in the MTL contains sufficient information …

Neurochemical Effects Of Sepsis On The Brain, Tatiana Barichello, Vijayasree V Giridharan, Carlos Henrique R Catalão, Cristiane Ritter, Felipe Dal-Pizzol

Faculty, Staff and Student Publications

Sepsis is a life-threatening organ dysfunction triggered by a dysregulated host immune response to eliminate an infection. After the host immune response is activated, a complex, dynamic, and time-dependent process is triggered. This process promotes the production of inflammatory mediators, including acute-phase proteins, complement system proteins, cytokines, chemokines, and antimicrobial peptides, which are required to initiate an inflammatory environment for eliminating the invading pathogen. The physiological response of this sepsis-induced systemic inflammation can affect blood-brain barrier (BBB) function; subsequently, endothelial cells produce inflammatory mediators, including cytokines, chemokines, and matrix metalloproteinases (MMPs) that degrade tight junction (TJ) proteins and decrease BBB …

A growing body of evidence suggests that dysbiosis of the human gut microbiota is associated with neurodegenerative diseases like Alzheimer's disease (AD) via neuroinflammatory processes across the microbiota-gut-brain axis. The gut microbiota affects brain health through the secretion of toxins and short-chain fatty acids, which modulates gut permeability and numerous immune functions. Observational studies indicate that AD patients have reduced microbiome diversity, which could contribute to the pathogenesis of the disease. Uncovering the genetic basis of microbial abundance and its effect on AD could suggest lifestyle changes that may reduce an individual's risk for the disease. Using the largest genome-wide …

Genome-Wide Crispr Screens Reveal Zatt As A Synthetic Lethal Target Of Top2-Poison Etoposide That Can Act In A Tdp2-Independent Pathway, Jeong-Min Park, Huimin Zhang, Litong Nie, Chao Wang, Min Huang, Xu Feng, Mengfan Tang, Zhen Chen, Yun Xiong, Namsoo Lee, Siting Li, Ling Yin, Traver Hart, Junjie Chen

Faculty, Staff and Student Publications

Etoposide (ETO) is an anticancer drug that targets topoisomerase II (TOP2). It stabilizes a normally transient TOP2-DNA covalent complex (TOP2cc), thus leading to DNA double-strand breaks (DSBs). Tyrosyl-DNA phosphodiesterases two (TDP2) is directly involved in the repair of TOP2cc by removing phosphotyrosyl peptides from 5'-termini of DSBs. Recent studies suggest that additional factors are required for TOP2cc repair, which include the proteasome and the zinc finger protein associated with TDP2 and TOP2, named ZATT. ZATT may alter the conformation of TOP2cc in a way that renders the accessibility of TDP2 for TOP2cc removal. In this study, our genome-wide clustered regularly …

Ravindranath, Narendranath M. Ravindranath, Carly J. Amato-Menker, Fatiha El Hilali, Senthamil R. Selvan, Edward J Filippone, Luis Eduardo Morales-Buenrostro

Department of Medicine Faculty Papers

Rheumatoid arthritis (RA) is a progressive, inflammatory, autoimmune, symmetrical polyarticular arthritis. It is characterized by synovial infiltration and activation of several types of immune cells, culminating in their apoptosis and antibody generation against "altered" autoantigens. β2-microglobulin (β2m)-associated heavy chains (HCs) of HLA antigens, also known as closed conformers (Face-1), undergo "alteration" during activation of immune cells, resulting in β2m-free structural variants, including monomeric open conformers (Face-2) that are capable of dimerizing as either homodimers (Face-3) or as heterodimers (Face-4). β2m-free HCs uncover the cryptic epitopes that can elicit antibodies (Abs). We report here the levels of IgM and IgG Abs …

The Prognostic Value Of Baseline Clinical And Radiologic Imaging Features In Patients With Unresectable Hepatocellular Carcinoma Treated With Atezolizumab Plus Bevacizumab, Mikhail Bogdanov

Faculty, Staff and Student Publications

Membrane asymmetry means that the two sides of membrane are structurally, physically and functionally different. Membrane asymmetry is largely related to the lipid sidedness and particularly to compositional (lipid head and acyl group) and physical (lipid packing order, charge, hydration and H-bonding interactions) differences in the inner and outer leaflets of lipid bilayer. Chemically, structurally and conformationally different non-covalent bound lipid molecules are physically fluid and deformable and enable to interact dynamically to form transient arrangements with asymmetry both perpendicular and parallel to the plane of the lipid bilayer. Although biological membranes are almost universally asymmetric however the asymmetry is …
