title: High isoprostane level in cardinal ligament-derived fibroblasts and urine sample of women with uterine prolapse.
abstract: We studied the isoprostane level, a well-recognised biomarker of oxidative stress, from women with uterine prolapse and age-matched female controls without prolapse. Cardinal ligament-derived fibroblasts explanted from women with prolapse showed a significant increased level of isoprostane production (P < 0.05) compared with those derived from controls. This concurs with elevated urinary isoprostane levels identified among women with prolapse (P < 0.001) compared with controls. In addition, the matrix metalloproteinase 2 mRNA was significantly increased (P= 0.004) among women with uterine prolapse. Parallel findings of increased isoprostane in cardinal ligament and urine sample among women with prolapse suggest that oxidative stress might be involved in the development of uterine prolapse.
