Pseudomonas aeruginosa PqsA Is an Anthranilate-Coenzyme A Ligase
(East Carolina University, 2008-02)Pseudomonas aeruginosa is an opportunistic human pathogen which relies on several intercellular signaling systems for optimum population density-dependent regulation of virulence genes. The Pseudomonas quinolone signal ... -
Pseudomonas aeruginosa relA Contributes to Virulence in Drosophila melanogaster
(East Carolina University, 2004-10)The stringent response is a mechanism by which bacteria adapt to nutritional deficiencies through the production of the guanine nucleotides ppGpp and pppGpp, produced by the RelA enzyme. We investigated the role of the ... -
The Pseudomonas Quinolone Signal Regulates rhl Quorum Sensing in Pseudomonas aeruginosa
(East Carolina University, 2000-05)The opportunistic pathogen Pseudomonas aeruginosa uses intercellular signals to control the density-dependent expression of many virulence factors. The las and rhl quorum-sensing systems function, respectively, through the ... -
The pseudorabies virus UL28 protein enters the nucleus after coexpression with the herpes simplex virus UL15 protein
(East Carolina University, 1997-12)Herpesvirus DNA is packaged into capsids in the nuclei of infected cells in a process requiring at least six viral proteins. Of the proteins required for encapsidation of viral DNA, UL15 and UL28 are the most conserved among ... -
Quantitative phosphoproteome analysis of embryonic stem cell differentiation toward blood
(2015-05)Murine embryonic stem (ES) cells can differentiate in vitro into three germ layers (endodermic, mesodermic, ectodermic). Studies on the differentiation of these cells to specific early differentiation stages has been aided ... -
Quinolone signaling in the cell-to-cell communication system of Pseudomonas aeruginosa
(East Carolina University, 1999-09-28)Numerous species of bacteria use an elegant regulatory mechanism known as quorum sensing to control the expression of specific genes in a cell-density dependent manner. In Gram-negative bacteria, quorum sensing ... -
Raf-Induced Vascular Endothelial Growth Factor Augments Kaposi's Sarcoma-Associated Herpesvirus Infection
(East Carolina University, 2004-12)Recombinant green fluorescent protein encoding Kaposi’s sarcoma-associated herpesvirus (rKSHV.152) infection of -estradiol stimulated human foreskin fibroblasts (HFF) or HFF/ B-Raf[FF]:ER (expressing a weaker form of ... -
Raman spectroscopy: the gateway into tomorrow's virology
(East Carolina University, 2006-06-28)In the molecular world, researchers act as detectives working hard to unravel the mysteries surrounding cells. One of the researchers' greatest tools in this endeavor has been Raman spectroscopy. Raman spectroscopy is a ... -
Raman tweezers provide the fingerprint of cells supporting the late stages of KSHV reactivation
(East Carolina University, 2009-08)Kaposi's sarcoma-associated herpesvirus (KSHV) has both latent and lytic phases of replication. The molecular switch that triggers a reactivation is still unclear. Cells from S phase of cell cycle provide apt conditions ... -
Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR Cascade Inhibitors: How Mutations Can Result in Therapy Resistance and How to Overcome Resistance
(2012-10)The Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR cascades are often activated by genetic alterations in upstream signaling molecules such as receptor tyrosine kinases (RTK). Integral components of these pathways, Ras, B-Raf, ... -
Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR Inhibitors: Rationale and Importance to Inhibiting These Pathways in Human Health
(2011-03)The Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR cascades are often activated by genetic alterations in upstream signaling molecules such as receptor tyrosine kinases (RTK). Integral components of these pathways, Ras, B-Raf, ... -
RecA and RadA Proteins of Brucella abortus Do Not Perform Overlapping Protective DNA Repair Functions following Oxidative Burst
(East Carolina University, 2006-07)Very little is known about the role of DNA repair networks in Brucella abortus and its role in pathogenesis. We investigated the roles of RecA protein, DNA repair, and SOS regulation in B. abortus. While recA mutants in ... -
Recent discoveries in the cycling, growing and aging of the p53 field
(2012-12)The P53 gene and it product p53 protein is the most studied tumor suppressor, which was considered as oncogene for two decades until 1990. More than 60 thousand papers on the topic of p53 has been abstracted in Pubmed. ... -
Recent progress in genetics of aging, senescence and longevity: focusing on cancer-related genes
(2012-12)It is widely believed that aging results from the accumulation of molecular damage, including damage of DNA and mitochondria and accumulation of molecular garbage both inside and outside of the cell. Recently, this paradigm ... -
Recent progress in targeting cancer
(2011-12)In recent years, numerous new targets have been identified and new experimental therapeutics have been developed. Importantly, existing non-cancer drugs found novel use in cancer therapy. And even more importantly, new ... -
The Redox-Sensitive Transcriptional Activator OxyR Regulates the Peroxide Response Regulon in the Obligate Anaerobe Bacteroides fragilis
(East Carolina University, 2000-09)The peroxide response-inducible genes ahpCF, dps, and katB in the obligate anaerobe Bacteroides fragilis are controlled by the redox-sensitive transcriptional activator OxyR. This is the first functional oxidative ...
