Pseudomonas aeruginosa is an opportunistic pathogen that establishes a chronic lung infection in individuals afflicted with cystic fibrosis. Here, we announce the draft genome of P. aeruginosa strain PAO579, an alginate-overproducing derivative of strain PAO381.

Pseudomonas aeruginosa is a Gram negative, opportunistic pathogen that uses the overproduction of alginate, a surface polysaccharide, to form biofilms in vivo. Overproduction of alginate, also known as mucoidy, affords the bacterium protection from the host's defenses and facilitates the establishment of chronic lung infections in individuals with cystic fibrosis. Expression of the alginate biosynthetic operon is primarily controlled by the alternative sigma factor AlgU (AlgT/σ22). In a nonmucoid strain, AlgU is sequestered by the transmembrane antisigma factor MucA to the cytoplasmic membrane. AlgU can be released from MucA via regulated intramembrane proteolysis by proteases AlgW and MucP causing the …

A doença Renal Policística Autossômica Dominante (DRPAD) é causada por mutações em um de dois genes, PKD1 ou PKD2, que resultam em acúmulos de cistos nos rins. O objetivo deste trabalho foi verificar a existência de possíveis associações entre variantes em genes de citocinas e em receptores de citocinas para as posições IL1A-889 (rs1800587), IL1B-511, +3962 (rs16944, rs1143634), IL1R1970 (rs2234650), IL1RA11100 (rs315952), IL4RA+1902 (rs1801275), IL12-1188 (rs3212227), IFNG+874 (rs2430561), TGFB1códon 10, códon 25 (rs1982073, rs1800471), TNF-308, -238 (rs1800629, rs361525), IL2-330, +166 (rs2069762, rs2069763), IL4-1098, -590, -33 (rs2243248, rs2243250, rs2070874), IL6-174, nt565 (rs1800795, rs1800797) e IL10-1082,-819,-592 (rs1800896, rs1800871, rs1800872) e a DRPAD. …
Chronic Paracetamol Treatment Influences Indices Of Reactive Oxygen Species Accumulation In The Aging Fischer 344 X Brown Norway Rat Aorta, Kevin M. Rice, Sarath Meduru, Sunil K. Kakarla, Anjaiah Katta, Sriram P. Mupparaju, Brent Kidd, Lynne J. Goebel, Eric R. Blough

Previous reports have demonstrated that increased levels of reactive oxygen species (ROS) and alterations in cell signaling characterize aging in the Fischer 344 X Brown Norway (FBN) rat aorta. Other work has suggested that increases in ROS may be related to vascular wall thickening and the development of hypertension. Paracetamol (acetaminophen) is a potent antioxidant that has been found to diminish free radicals in ischemia-reperfusion studies. However, it remains unclear whether chronic paracetamol administration influences signaling or ROS accumulation in the aging aorta. FBN rats (27 months old; n=8) were subjected to 6 months of treatment with a therapeutic dose …

The effects of ageing on the cardiovascular system contribute to substantial alterations in cellular morphology and function. The variables regulating these changes are unknown; however, one set of signalling molecules that may be of particular importance in mediating numerous cellular responses, including control of cell growth, differentiation and adaptation, are the proteins associated with the mitogen-activated protein kinase (MAPK) signalling systems. The MAPKs, in conjunction with the p70 S6k signalling cascade, have emerged as critical components for regulating numerous mechanotransduction-related cellular responses. Here we investigate the ability of uniaxial stretch to activate the MAPK and p70 S6k pathways in adult …
