Emergence of Pseudomonas aeruginosa strains producing high levels of persister cells in patients with cystic fibrosis.
The majority of cystic fibrosis (CF) patients succumb to a chronic infection of the airway with Pseudomonas aeruginosa. Paradoxically, pathogenic strains are often susceptible to antibiotics, but theExpand
Killing by Bactericidal Antibiotics Does Not Depend on Reactive Oxygen Species
Antibiotic Mechanisms Revisited Several recent studies have suggested that bactericidal antibiotics kill cells by a common mechanism involving reactive oxygen species (ROS). Two groups tested thisExpand
Pseudomonas aeruginosa Biofilms in Disease
Pseudomonas aeruginosa is a ubiquitous organism that is the focus of intense research because of its prominent role in disease. Due to its relatively large genome and flexible metabolic capabilities,Expand
RefZ facilitates the switch from medial to polar division during spore formation in Bacillus subtilis.
During sporulation, Bacillus subtilis redeploys the division protein FtsZ from midcell to the cell poles, ultimately generating an asymmetric septum. Here, we describe a sporulation-induced protein,Expand
Deficiencies in Pro-thyrotropin-releasing Hormone Processing and Abnormalities in Thermoregulation in Cpefat/fat Mice*
Cpefat/fat mice are obese, diabetic, and infertile. They have a mutation in carboxypeptidase E (CPE), an enzyme that converts prohormone intermediates to bioactive peptides. The Cpefat mutation leadsExpand
Prohormone-Convertase 1 Processing Enhances Post-Golgi Sorting of Prothyrotropin-releasing Hormone-derived Peptides*
Rat prothyrotropin-releasing hormone (pro-TRH) is endoproteolyzed within the regulated secretory pathway of neuroendocrine cells yielding five TRH peptides and seven to nine other unique peptides.Expand
Persister eradication: lessons from the world of natural products.
Persisters are specialized survivor cells that protect bacterial populations from killing by antibiotics. Persisters are dormant phenotypic variants of regular cells rather than mutants. BactericidalExpand
Near-zero growth kinetics of Pseudomonas putida deduced from proteomic analysis.
Intensive microbial growth typically observed in laboratory rarely occurs in nature. Because of severe nutrient deficiency, natural populations exhibit near-zero growth (NZG). There is aExpand
A Screen for and Validation of Prodrug Antimicrobials
ABSTRACT The rise of resistant pathogens and chronic infections tolerant to antibiotics presents an unmet need for novel antimicrobial compounds. Identifying broad-spectrum leads is challenging dueExpand
Disruption of disulfide bond formation alters the trafficking of prothyrotropin releasing hormone (proTRH)-derived peptides
Rat prothyrotropin releasing hormone (proTRH) is processed in the regulated secretory pathway (RSP) of neuroendocrine cells yielding five TRH peptides and several non-TRH peptides. It is notExpand
