Severe and moderate PBOO were induced by urethral ligation using 3\u2010Fr and 4\u2010Fr catheters, respectively, for 6\u2009weeks. After 6 weeks, the <jats:italic>in vitro<\/jats:italic> contractile responses to carbachol, electrical field stimulation, ATP and KCl were measured in bladder strips. In addition, mRNA and protein expression of nuclear factor kappa B (NF\u2010\u03baB) hypoxia\u2010inducible factor (HIF) and nuclear factor, erythroid 2\u2010like 2 (Nrf2) in bladder were determined by real\u2010time polymerase chain reaction and western blotting. Malondialdehyde (MDA) levels in bladder tissues were also determined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Rats in the severe PBOO group had the highest bladder weight. Detrusor strips from rats in the severe PBOO group exhibited 61%\u201382% smaller contractile responses to all four stimuli than those from the sham\u2010operated group. Activity of NF\u2010\u03baB as an inflammatory marker was increased in the severe PBOO group, whereas HIF\u20101\u03b1 and HIF\u20102\u03b2 protein levels were increased significantly in the moderate PBOO group. A master regulator of oxidative stress, Nrf2 expression was increased in all obstructed rats. MDA levels were higher in the severe PBOO group than in sham\u2010operated group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The results of the present study reveal the importance of oxidative stress\u2010induced NF\u2010\u03baB signaling in bladder dysfunction with severe obstruction. Altered HIF signaling may contribute to the functional impairment after PBOO. Novel and evolving therapies targeting oxidative and\/or inflammatory pathways may be a reasonable strategy for the management of lower urinary tract symptoms or benign prostatic hyperplasia.<\/jats:p><\/jats:sec>","DOI":"10.1111\/luts.12211","type":"journal-article","created":{"date-parts":[[2017,12,28]],"date-time":"2017-12-28T07:32:42Z","timestamp":1514446362000},"source":"Crossref","is-referenced-by-count":16,"title":["Effects
