Immunosuppression resulted in reactivation with increased lung bacillary burden.Using this rabbit model,we isolated bacillary RNA from infected rabbit lungs and assessed transcriptional profiles of bacillary genes using RT-PCR to examine genes differentially regulated during active replication,persistence,steroid-induced reactivation,and Systemic adenoviral gene delivery to orthotopic murine RESULTS Warfarin pretreatment reduced gene delivery to liver,spleen and lung.Kupffer cell ablation increased persistence of adenoviruses in blood but didn't affect biodistribution significantly.Depletion of Kupffer cells combined with thrombocytopenia doubled the systemic gene delivery of 5/3 chimeric adenovirus to tumors (p Increased persistence of lung gene eion usinglt; 0.05).Systemic adenoviral gene delivery to orthotopic murine RESULTS Warfarin pretreatment reduced gene delivery to liver,spleen and lung.Kupffer cell ablation increased persistence of adenoviruses in blood but didn't affect biodistribution significantly.Depletion of Kupffer cells combined with thrombocytopenia doubled the systemic gene delivery of 5/3 chimeric adenovirus to tumors (p Increased persistence of lung gene eion usinglt; 0.05).

Screening of homologous recombination gene

Deficiencies in the DNA-double strand break (DSB) repair system may be critical in the generation and persistence of chromosomal gains or losses during lung tumorigenesis.Therefore,we examined whether specific DSB repair gene polymorphisms were associated with an increase in tobacco-induced DNA damage,including gene mutations (p53 and KRAS RESEARCH ARTICLE Increased persistence of lung gene Increased persistence of lung gene expression using plasmids containing the ubiquitin C or elongation factor 1 promoter DR Gill 1,SE Smyth ,CA Goddard2,IA Pringle,CF Higgins3,WH Colledge2 and SC Hyde1 1GeneMedicine Research Group,Nufeld Department of Clinical Laboratory Sciences,University of Oxford,John Radcliffe Hospital,Pseudomonas aeruginosa Rugose Small-Colony VariantsPseudomonas aeruginosa is recognized for its ability to colonize diverse habitats,ranging from soil to immunocompromised people.The formation of surface-associated communities called biofilms is one factor thought to enhance colonization and persistence in these diverse environments.Another factor is the ability of P.aeruginosa to diversify genetically,generating phenotypically distinct

Pseudomonas aeruginosa RsmA Plays an Important Role

The murine model of chronic lung infection using P.aeruginosa-laden agarose beads was established by following previously described protocols (24,35).Briefly,for preparation of the agarose beads,bacteria (P.aeruginosa strain PAO1 or PAZH13) were grown to late log phase and mixed at a 1/10 ratio with 2% agarose in PBS (pH 7.4).The mixture Pseudomonas aeruginosa RsmA Plays an Important RoleThe ability of Pseudomonas aeruginosa to cause a broad range of infections in humans is due,at least in part,to its adaptability and its capacity to regulate the expression of key virulence genes in response to specific environmental conditions.Multiple two-component response regulators have been shown to facilitate rapid responses to these environmental conditions,including the Pseudomonas aeruginosa AES-1 exhibits increased virulence Pseudomonas aeruginosa,the leading cause of morbidity and mortality in people with cystic fibrosis (CF),adapts for survival in the CF lung through both mutation and gene expression changes.Frequent clonal strains such as the Australian Epidemic Strain-1 (AES-1),have increased ability to establish infection in the CF lung and to superimpose
