Dry Eye disease causes discomfort and pain in millions of patients. Using a mouse acute desiccating stress (DS) model we show that DS induces a reduction in intraepithelial corneal nerve (ICN) density, corneal sensitivity, and apical extension of the intraepithelial nerve terminals (INTs) that branch from the subbasal nerves (SBNs). Topical application of 0.02% Mitomycin C (MMC) or vehicle alone has no impact on the overall loss of axon density due to acute DS. Chronic dry eye, which develops progressively as C57BL/6 mice age, is accompanied by significant loss of the ICNs and corneal sensitivity between 2 and ...


Changes In The Proliferation And Gene Expression Of Huvecs In Response To Treatment With Plant Secondary Metabolites, Caleigh Howard 2018 Pepperdine University

Changes In The Proliferation And Gene Expression Of Huvecs In Response To Treatment With Plant Secondary Metabolites, Caleigh Howard

Seaver College Research And Scholarly Achievement Symposium

Medicinal plants have historically been a valuable source of new drugs, and Southern California possesses a rich collection of native plants which have been used as medicines by native people groups for thousands of years. Angiogenesis is the biological process of new blood-vessel growth from endothelial cells. It is an essential part of the wound-healing process, and increased angiogenesis has also been implicated in the growth of some types of cancerous tumors. In this study, extracts of the Southern Californian native plants Red shanks (Adenostoma sparsifolium) and the alkaloid extract of Jimson weed (Datura wrightii) were tested for their angiogenic ...

During neural development, epigenetic modulation of chromatin acetylation is part of a dynamic, sequential and critical process to steer the fate of multipotent neural progenitors toward a specific lineage. Pan-HDAC inhibitors (HDCis) trigger neuronal differentiation by generating an "acetylation" signature and promoting the expression of neurogenic bHLH transcription factors. Our studies and others have revealed a link between neuronal differentiation and increase of mitochondrial mass. However, the neuronal regulation of mitochondrial biogenesis has remained largely unexplored. Here, we show that the HDACi, sodium butyrate (NaBt), promotes mitochondrial biogenesis via the NRF-1/Tfam axis in embryonic hippocampal progenitor cells and neuroprogenitor-like ...

Investigating Peroxiredoxins Impact On Amps, Noah Earland 2018 Southern Methodist University

Investigating Peroxiredoxins Impact On Amps, Noah Earland

SMU Journal of Undergraduate Research

The Orr-Radyuk lab is interested in understanding the link between aging and genetic influences controlling the cell’s redox state, as determined by enzymes involved in reducing and oxidizing (redox) reactions. They have observed that Drosophila normally exhibit a shift towards a pro-oxidizing cellular environment and spikes in AMP levels, independent of infections, when they reach old age. Additionally, peroxiredoxins (PRXs), a family of thiol-dependent peroxidases, have been shown to impact lifespan, and regulate the same pro-oxidizing shift seen in advanced age. Beyond their peroxidase functions, RXRs can also interact with signaling pathways related to immunity. Previous data showed that ...


Role Of Jip1-Jnk Signaling In Beta-Cell Function And Autophagy, Seda Barutcu 2018 University of Massachusetts Medical School

Role Of Jip1-Jnk Signaling In Beta-Cell Function And Autophagy, Seda Barutcu

GSBS Dissertations and Theses

Proper functioning of endocrine cells is crucial for organismal homeostasis. The underlying mechanisms that fine-tune the amount, and the timing of hormone secretion are not clear. JIP1 / MAPK8IP1 (JNK interacting protein 1) is a scaffold protein that mediates cellular stress response, and is highly expressed in endocrine cells, including insulin secreting b-cells in pancreas islets. However, the role of JIP1 in b-cells is unclear. This study demonstrates that b-cell specific Jip1 ablation results in decreased glucose-induced insulin secretion, without a change in Insulin1 and Insulin2 gene expression. Inhibition of both JIP1-kinesin interaction, and JIP1-JNK interaction by genetic mutations also resulted ...

Systems Modeling Accurately Predicts Responses To Genotoxic Agents And Their Synergism With Bcl-2 Inhibitors In Triple Negative Breast Cancer Cells., Federico Lucantoni, Andreas U Lindner, Norma O'Donovan, Heiko Düssmann, Jochen Hm Prehn

Physiology and Medical Physics Articles

Triple negative breast cancer (TNBC) is an aggressive form of breast cancer which accounts for 15-20% of this disease and is currently treated with genotoxic chemotherapy. The BCL2 (B-cell lymphoma 2) family of proteins controls the process of mitochondrial outer membrane permeabilization (MOMP), which is required for the activation of the mitochondrial apoptosis pathway in response to genotoxic agents. We previously developed a deterministic systems model of BCL2 protein interactions, DR_MOMP that calculates the sensitivity of cells to undergo mitochondrial apoptosis. Here we determined whether DR_MOMP predicts responses of TNBC cells to genotoxic agents and the re-sensitization of resistant cells ...

Cloning And Spatiotemporal Expression Of Xenopus Laevis Apolipoprotein Ci, Jyotsna Sridharan, Tomomi Haremaki, Daniel C. Weinstein

Publications and Research

Apolipoprotein CI (ApoCI) belongs to the Apolipoprotein superfamily, members of which are involved in lipid transport, uptake and homeostasis. Excessive ApoCI has been implicated in atherosclerosis and Alzheimer’s disease in humans. In this study we report the isolation of Xenopus laevis apoCI and describe the expression pattern of this gene during early development, using reverse transcription polymerase chain reaction and whole mount in situ hybridization. Xenopus apoCI is enriched in the dorsal ectoderm during gastrulation, and is subsequently expressed in sensory placodes, neural tube and cranial neural crest. These data suggest as yet uncharacterized roles for ApoCI during early ...

The Role Of Mdm2 In Dna Damage Signaling, Stanley Tam

School of Arts & Sciences Theses

The overexpression of the oncogene MDM2 is common in a variety of human cancers. MDM2 overexpression is known to increase genome instability in cells by delaying DNA double strand break repair and γH2AX levels. This study explores the knockdown of MDM2 and how it may affect DNA damage signaling.


Altering Oligomerization Of Epha2 Via Mutations In The Intracellular Domain, Ryan W. Lingerak 2018 The University of Akron

Altering Oligomerization Of Epha2 Via Mutations In The Intracellular Domain, Ryan W. Lingerak

Honors Research Projects

Eph receptor tyrosine kinases (RTKs) are activated by membrane-bound ligands called ephrins. Eph RTKs are divided into two subclasses, each activated by a specific classes of the ligand ephrin. The overexpression of Eph receptors is correlated to cancer cell metastasis in several different types of cancers. Studies with the EphA2 extracellular domain (ECD) and ephrinA1 ligand have shown that upon binding of ephrin to the receptor, EphA2 undergoes increased oligomerization and activation. This indicates that oligomerization is intimately connected to kinase activity. High resolution crystal structures of the EphA2 ECD have revealed some details of these ligand bound oligomers, as ...

Central nervous system (CNS) demyelination represents the pathological hallmark of multiple sclerosis (MS) and contributes to other neurological conditions. Quantitative and specific imaging of demyelination would thus provide critical clinical insight. Here, we investigated the possibility of targeting axonal potassium channels to image demyelination by positron emission tomography (PET). These channels, which normally reside beneath the myelin sheath, become exposed upon demyelination and are the target of the MS drug, 4-aminopyridine (4-AP). We demonstrate using autoradiography that 4-AP has higher binding in non-myelinated and demyelinated versus well-myelinated CNS regions, and describe a fluorine-containing derivative, 3-F-4-AP, that has similar pharmacological properties ...

Purpose: Progenitor cells of the limbal epithelium reside in a discrete area peripheral to the more differentiated corneal epithelium and maintain tissue homeostasis. What regulates the limbal-corneal epithelial boundary is a major unanswered question. Ephrin-A1 ligand is enriched in the limbal epithelium, whereas EphA2 receptor is concentrated in the corneal epithelium. This reciprocal pattern led us to assess the role of ephrin-A1 and EphA2 in limbal-corneal epithelial boundary organization.

Methods: EphA2-expressing corneal epithelial cells engineered to express ephrin-A1 were used to study boundary formation in vitro in a manner that mimicked the relative abundance of these juxtamembrane signaling proteins in ...


Jak/Stat Signaling Regulates Gametogenesis And Age-Related Reproductive Maintenance, Michelle Suzanne Giedt 2018 University of Kentucky

Jak/Stat Signaling Regulates Gametogenesis And Age-Related Reproductive Maintenance, Michelle Suzanne Giedt

Theses and Dissertations--Biology

Cell signaling is central to integration of internal and external cues that regulate development and homeostasis. Most development is thought of as pre-adult, but limited developmental processes occur in adults. Gametogenesis incorporates elements of both these facets, with a distinct developmental plan for gamete synthesis which is regulated by integration of homeostatic inputs such as nutrient status, and environmental cues. Signaling pathways integrate and transduce information from these cues to evoke a response. A decline in homeostasis and subsequent cues occurs over time, in the case of reproductive tissues leading to a progressive loss of fertility. The Janus Kinase and ...

Meiothermus ruber Genome Analysis Project

In this project we investigated the biological function of the genes b3725, b3726, b3727, b3728 and Mrub_2518, Mrub_2519, Mrub_2520 and Mrub_2521 (KEGG map number 02010). We predict that these genes encode the components of a Phosphate ABC transporter: Orthologous genes Mrub_2518 (DNA coordinates 2565359..2566438) and b3728 encodes the periplasmic phosphate binding component; Orthologous genes Mrub_2519 (DNA coordinates 2566499..2567485) and b3727, and Mrub_2520 (DNA coordinates 2567496..2568326) and b3726 encode for the two transmembrane proteins; Orthologous genes Mrub_2521 (DNA coordinates 2568338..2569159) and b3725 encode for the ATP binding protein within the cytoplasm. Within the two species, M. ruber ...


Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, Daniel Pollack 2018 CUNY City College

Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, Daniel Pollack

Master's Theses

Thymic epithelial cells (TEC) are essential for a proper adaptive immune response by regulating thymocyte development and establishing central tolerance. In the thymus, TECs differentially express Wnt proteins, which activate canonical and non-canonical Wnt signaling pathways. Wnt signaling is thought to regulate cell survival, proliferation, and development although the direct molecular mechanisms in TECs have yet to be elucidated. The inducible inhibition of canonical Wnt signaling with Dkk1 leads to a rapid loss of TEC progenitors as well as a decline in mature Aire-expressing mTECs. Therefore, we explore the role of Wnt ligands potentially responsible for stimulating and/or regulating ...

Wild-Type P53 Enhances Endothelial Barrier Function By Mediating Rac1 Signalling And Rhoa Inhibition, Nektarios Barabutis, Christiana Dimitropoulou, Betsy Gregory, John D. Catravas 2018 Old Dominion University

Wild-Type P53 Enhances Endothelial Barrier Function By Mediating Rac1 Signalling And Rhoa Inhibition, Nektarios Barabutis, Christiana Dimitropoulou, Betsy Gregory, John D. Catravas

Bioelectrics Publications

Inflammation is the major cause of endothelial barrier hyper-permeability, associated with acute lung injury and acute respiratory distress syndrome. This study reports that p53 "orchestrates" the defence of vascular endothelium against LPS, by mediating the opposing actions of Rac1 and RhoA in pulmonary tissues. Human lung microvascular endothelial cells treated with HSP90 inhibitors activated both Rac1- and P21-activated kinase, which is an essential element of vascular barrier function. 17AAG increased the phosphorylation of both LIMK and cofilin, in contrast to LPS which counteracted those effects. Mouse lung microvascular endothelial cells exposed to LPS exhibited decreased expression of phospho-cofilin. 17AAG treatment ...

Bioelectrics Publications

Several studies have shown that different control plasmids may cause antitumor action in different murine tumor models after gene electrotransfer (GET). Due to the differences in GET protocols, plasmid vectors, and experimental models, the observed antitumor effects were incomparable. Therefore, the current study was conducted comparing antitumor effectiveness of three different control plasmids using the same GET parameters. We followed cytotoxicity in vitro and the antitumor effect in vivo after GET of control plasmids pControl, pENTR/U6 scr and pVAX1 in B16.F10 murine melanoma cells and tumors. Types of cell death and upregulation of selected cytosolic DNA sensors and ...
