Markers of oxidative stress, cell cycle dysregulation and the androgen receptor do not appear to be uniquely associated with lichen sclerosus urethral stricture disease.
Men with low testosterone levels demonstrate decreased AR and TIE-2 expression and lower vessel counts in periurethral tissue samples of urethral strictures.
Moreover, prior urethral stricture (p = 0.036) and higher ASA-classification (p = 0.039) were positively correlated with explantation in univariate analysis for AUS.
Moreover, miR-146a-containing exosomes were taken up by fibroblasts and inhibited fibroblast activation and associated inflammatory responses, a finding that may underlie the therapeutic mechanism for suppression of urethral stricture.
The results of this study indicate a substantial role of SRF in prostatic fibroblasts and we suggest that SRF silencing might be used for the treatment of urethral strictures to achieve a durably patent urethra.
Men with low testosterone levels demonstrate decreased AR and TIE-2 expression and lower vessel counts in periurethral tissue samples of urethral strictures.
By contrast, flow cytometry, real-time PCR detection, and immunofluoresecent staining showed that urethral stricture resulted in decreased expression of CXCR3.
This study investigated whether miR-21 modification can improve the therapeutic efficacy of ADSCs against urethral fibrosis to limit urethral stricture recurrence.
