Bacterial cupredoxin azurin as an inducer of apoptosis and regression in human breast cancer
(2004)Azurin, a copper-containing redox protein released by the pathogenic bacterium Pseudomonas aeruginosa, is highly cytotoxic to the human breast cancer cell line MCF-7, but is less cytotoxic toward p53-negative (MDA-MB-157) ...

C2, An Unusual Filamentous Bacterial Virus: Protein Sequence and Conformation, DNA Size and Conformation, and Nucleotide/Subunit Ratio
(1995)Inovirus C2 is 1295 nm long and 6.8 nm in diameter, and its mass is 24 million Da. Its genome is a topologically circular, single-stranded DNA molecule of 8100 nucleotides. The DNA is packed in the virion as two antiparallel ...

Down-regulation of glutatione S-transferase α 4 (hGSTA4) in the muscle of thermally injured patients is indicative of susceptibility to bacterial infection
(2012)Patients with severe burns are highly susceptible to bacterial infection. While immunosuppression facilitates infection, the contribution of soft tissues to infection beyond providing a portal for bacterial entry remains ...

Article
Drosophila melanogaster as a model host for studying Pseudomonas aeruginosa infection
(2009)Conservation of host signaling pathways and tissue physiology between Drosophila melanogaster and mammals allows for the modeling of human host-pathogen interactions in Drosophila. Here we present the use of genetically ...

Article
Homeostatic interplay between bacterial cell-cell signaling and iron in virulence
(2010)Pathogenic bacteria use interconnected multi-layered regulatory networks, such as quorum sensing (QS) networks to sense and respond to environmental cues and external and internal bacterial cell signals, and thereby adapt ...

Article
Isolation of isoflavones from soy-based fermentations of the erythromycin-producing bacterium Saccharopolyspora erythraea
(1997)A search for an abundant and economical source of isoflavones, particularly genistein, led to the discovery that the erythromycin-producing organism Saccharopolyspora erythraea also produces this promising new cancer-prevention ...

Article
The nucleotide-binding proteins Nubp1 and Nubp2 are negative regulators of ciliogenesis
(2014)Nucleotide-binding proteins Nubp1 and Nubp2 are MRP/MinD-type P-loop NTPases with sequence similarity to bacterial division site-determining proteins and are conserved, essential proteins throughout the Eukaryotes. They ...

Article
The pathogenic properties of a novel and conserved gene product, KerV, in proteobacteria
(2009)Identification of novel virulence factors is essential for understanding bacterial pathogenesis and designing antibacterial strategies. In this study, we uncover such a factor, termed KerV, in Proteobacteria. Experiments ...

Article
Profiling early infection responses: Pseudomonas aeruginosa eludes host defenses by suppressing antimocrobial peptide gene expression
(2005)Insights into the host factors and mechanisms mediating the primary host responses after pathogen presentation remain limited, due in part to the complexity and genetic intractability of host systems. Here, we employ the ...

Article
A quorum sensing regulated small volatile molecule reduces acute virulence and promotes chronic infection phenotypes
(2011)A significant number of environmental microorganisms can cause serious, even fatal, acute and chronic infections in humans. The severity and outcome of each type of infection depends on the expression of specific bacterial ...

Article
Ras-oncogenic Drosophila hindgut but not midgut cells use an inflammation-like program to disseminate to distant sites
(2013)The gastrointestinal tract is habitable by a variety of microorganisms and it is often a tissue inflicted by inflammation. Much discussion is raised in recent years about the role of microbiota in intestinal inflammation, ...

Article
Refinement of the gene locus for autosomal dominant medullary cystic kidney disease type 1 (MCKD1) and construction of a physical and partial transcriptional map of the region
(2001)Autosomal dominant medullary cystic kidney disease (MCKD) is an adult onset tubulointerstitial nephropathy that leads to salt wasting and end-stage renal failure. A gene locus (MCKD1) has been mapped on chromosome 1q21. ...

Article
Synergy between bacterial infection and genetic predisposition in intestinal dysplasia
(2009)Accumulating evidence suggests that hyperproliferating intestinal stem cells (SCs) and progenitors drive cancer initiation, maintenance, and metastasis. In addition, chronic inflammation and infection have been increasingly ...

Article
Use of molecular beacons and multi-allelic real-time PCR for detection of and discrimination between virulent Bacillus anthracis and other Bacillus isolates
(2009)The awareness of the threat of Bacillus anthracis, the causative agent of the disease anthrax, as a biowarfare and bioterrorism weapon has revived the development of new technologies for rapid and accurate detection of ...
