Overproduction of the exopolysaccharide alginate causes mucoid conversion in Pseudomonas aeruginosa and is a poor prognosticator in cystic fibrosis. The ECF σ factor AlgU and its cognate anti-σ factor MucA are two principal regulators of alginate production. Here, we report the identification of three positive regulators of alginate biosynthesis: PA4033 (designated mucE), PA3649 (designated mucP), and algW. MucE, a small protein (9.5 kDa), was identified as part of a global mariner transposon screen for new regulators of alginate production. A transposon located in its promoter caused the overexpression of MucE and mucoid conversion in P. aeruginosa strains PAO1 and PA14. …

The persistence of pain following surgery or trauma limits recovery, physical rehabilitation and the return to a normal quality of life. AYX1 is a compound developed for preventing the maintenance of post-surgical pain with a single intrathecal administration prior to surgery. Post-surgical pain arises from a combination of mechanical/incisional, inflammatory and often nerve trauma. Early in the development of pain following such injury, there are waves of gene regulation in DRG and spinal cord neurons leading to long-term sensitization and the maintenance of pain over time. These transcriptional events are necessary to the development and maintenance of pain and involve …
