Assessing cellular and genomic damage from environmental nickel using a GFP containing strain of Caenorhabditis elegans
(East Carolina University, 2013)Nickel is a naturally found mineral that has become widely used for many electronic devices. As use and subsequent discarding of nickel containing products continues exposure to nickel increases. Nickel can cause external ... -
Autocrine production of extracellular catalase prevents apoptosis of the human CEM T-cell line in serum-free medium.
(East Carolina University, 1993-05-15)CCRF-CEM is a human T-cell line originally isolated from a child with acute lymphoblastic leukemia. At cell densities > 2 x 10 cells per ml, CEM cells grow in serum-free medium, but at lower cell densities the cultures ... -
Cleaved Caspase-3 Response to Acute Resistance Exercise in Young and Old Men and Women : Relationship to Muscle Glycogen Content and 5'-AMP-Activated Protein Kinase (AMPK) Activity
(East Carolina University, 2011)In addition to suppressing protein synthesis and activating protein degradation in skeletal muscle and other cell types, 5'-AMP-activated protein kinase (AMPK) is known to stimulate nuclear apoptosis in non-muscle cells ... -
Comparison of ZnO nanoparticles and ZnCl₂ induced germ cell apoptosis in Caenorhabditis elegans
(East Carolina University, 2014)There is inadequate research data available on manufactured ZnO nanoparticles. Manufactured nanoparticles are widely used in various products and production of manufactured nanoparticles is becoming increasingly abundant. ... -
The cyclic GMP modulators YC-1 and zaprinast reduce vessel remodeling through anti-proliferative and pro-apoptotic effects
(East Carolina University, 2009-06)Guanosine-specific cyclic nucleotide signaling is suggested to serve protective actions in the vasculature; however, the influence of selective pharmacologic modulation of cyclic guanosine monophosphate (GMP)-synthesizing ... -
IDENTIFICATION OF NOVEL CYTOTOXIC PROSTAGLANDIN METABOLITES PRODUCED IN ARACHIDONOYL ETHANOLAMIDE-TREATED TUMOREGENIC KERATINOCYTES
(East Carolina University, 2012)Arachidonoyl ethanolamide (AEA) induces apoptosis in mouse tumorigenic keratinocytes (JWF-2 cells). Our previous data show that AEA is metabolized by COX-2 to pro-apoptotic J-series prostaglandins. COX-2 is an enzyme that ... -
The involvement of cap-independent mRNA translation in cell fate decisions
(East Carolina University, 2014)During cell stress many biochemical processes are shut down. For example, global mRNA translation initiation is inhibited due to the disruption of the cap-dependent mRNA recruitment mechanism. One specific example of ... -
LLL-3 inhibits STAT3 activity, suppresses glioblastoma cell growth and prolongs survival in a mouse glioblastoma model
(East Carolina University, 2009-01-13)Persistent activation of the signal transducer and activator of transcription 3 (STAT3) signalling has been linked to oncogenesis and the development of chemotherapy resistance in glioblastoma and other cancers. Inhibition ... -
Phorbol esters induce death in MCF-7 breast cancer cells with altered expression of protein kinase C isoforms. Role for p53-independent induction of gadd-45 in initiating death.
(East Carolina University, 1995-10)Protein kinase C (PKC) modulates growth, differentiation, and apoptosis in a cell-specific fashion. Overexpression of PKC-a in MCF-7 breast cancer cells (MCF-7-PKC-a cell) leads to expression of a more transformed phenotype. ... -
The Role of eIF4G-1 Isoforms and Live Cell Imaging of IRES-mediated Translation Initiation in Breast Cancer Cells
(East Carolina University, 2012)The development of cancer is a consequence of mutations that lead to dysfunctional cell processes such as unrestrained cell proliferation, resistance to apoptosis, and improper regulation of cell processes such as translation. ... -
Roles of the RAF/MEK/ERK Pathway in Cell Growth, Malignant Transformation and Drug Resistance
(East Carolina University, 2007-08)Growth factors and mitogens use the Ras/Raf/MEK/ERK signaling cascade to transmit signals from their receptors to regulate gene expression and prevent apoptosis. Some components of these pathways are mutated or aberrantly ... -
Synergistic Proapoptotic Activity of Recombinant Trail Plus the AKT Inhibitor Perifosine in Acute Myelogenous Leukemia Cells
(East Carolina University, 2008-11-15)To potentiate the response of acute myelogenous leukemia (AML) cells to TNF-Related Apoptosis- Inducing Ligand (TRAIL) cytotoxicity, we have examined the efficacy of a combination with perifosine, a novel phosphatidylinositol ... -
The Effects of Benzoic Acid in C. elegans: Germ Cell Apoptosis
(East Carolina University, 2017-05-05)Benzoic acid is widely consumed by humans everyday through means of fruit juices, soft drinks, pickles, salad dressings and more. However, the health impact of long-term benzoic acid exposure remains largely unknown. This ... -
THERAPEUTIC AND TOXICOLOGICAL EVALUATION OF BROAD-SPECTRUM ANTIMICROBIAL TRICLOSAN AS A CHEMOTHERAPEUTIC AGENT
(East Carolina University, 2019-05-07)Triclosan (TCS) is a phenolic antimicrobial incorporated in personal care products and medical devices. Interest in the antiproliferative properties of TCS has recently grown owing to its antilipogenic effects. Through the ... -
Tinigible Body Macrophages in Regulation of Germinal Center Reactions
(East Carolina University, 1998)Tingible body macrophages (TBM), long thought simply as scavengers of apoptotic lymphocytes, are located in the unique microenvironment of germinal centers in close proximity to antigen-retaining follicular dendritic cells ... -
Using death to one's advantage: HIV modulation of apoptosis
(East Carolina University, 2001-03)Infection by human immunodeficiency virus (HIV) is associated with an early immune dysfunction and progressive destruction of CD4+ T lymphocytes. This progressive disappearance of T cells leads to a lack of immune control ...
