Pelvic organ prolapse is a frequent health problem in women, encountered worldwide, its physiopathology being still incompletely understood. The integrity of the pelvic-supportive structures is a key element that prevents the prolapse of the pelvic organs. Numerous researchers have underlined the role of connective tissue molecular changes in the pathogenesis of pelvic organ prolapse and have raised the attention upon oxidative stress as an important element involved in its appearance. The advancements made over the years in terms of molecular biology have allowed researchers to investigate how the constituent elements of the pelvic-supportive structures react in conditions of oxidative stress. The purpose of this paper is to underline the importance of oxidative stress in the pathogenesis of pelvic organ prolapse, as well as to highlight the main oxidative stress molecular changes that appear at the level of the pelvic-supportive structures. Sustained mechanical stress is proven to be a key factor in the appearance of pelvic organ prolapse, correlating with increased levels of free radicals production and mitochondrial-induced fibroblasts apoptosis, the rate of cellular apoptosis depending on the intensity of the mechanical stress, and the period of time the mechanical stress is applied. Oxidative stress hinders normal cellular signaling pathways, as well as different important cellular components like proteins, lipids, and cellular DNA, therefore significantly interfering with the process of collagen and elastin synthesis.

氧化应激:骨盆器官脱垂的可能诱因。

盆腔器官脱垂是女性常见的健康问题,在世界范围内都遇到过,其生理病理学仍不完全清楚。骨盆支撑结构的完整性是防止骨盆器官脱垂的关键因素。许多研究人员强调了结缔组织分子变化在盆腔器官脱垂发病机理中的作用,并引起人们对氧化应激作为其出现的重要因素的关注。多年来在分子生物学方面取得的进步使研究人员能够研究骨盆支撑结构的组成元素在氧化应激条件下如何反应。本文的目的是强调氧化应激在盆腔器官脱垂发病机制中的重要性,并突出显示在骨盆支持结构水平出现的主要氧化应激分子变化。持续的机械压力被证明是盆腔器官脱垂的关键因素,与自由基产生水平增加和线粒体诱导的成纤维细胞凋亡,取决于机械应力强度的细胞凋亡率以及周期长短有关。随着时间的推移,会施加机械应力。氧化应激会阻碍正常的细胞信号通路,以及蛋白质,脂质和细胞DNA等不同的重要细胞成分,因此会显着干扰胶原蛋白和弹性蛋白的合成过程。持续的机械压力被证明是盆腔器官脱垂的关键因素,与自由基产生水平增加和线粒体诱导的成纤维细胞凋亡,取决于机械应力强度的细胞凋亡率以及周期长短有关。随着时间的推移,会施加机械应力。氧化应激会阻碍正常的细胞信号通路,以及不同的重要细胞成分(如蛋白质,脂质和细胞DNA),因此会显着干扰胶原蛋白和弹性蛋白的合成过程。持续的机械压力被证明是盆腔器官脱垂的关键因素,与自由基产生水平增加和线粒体诱导的成纤维细胞凋亡,取决于机械应力强度的细胞凋亡率以及周期长短有关。随着时间的推移,会施加机械应力。氧化应激会阻碍正常的细胞信号通路,以及不同的重要细胞成分(如蛋白质,脂质和细胞DNA),因此会显着干扰胶原蛋白和弹性蛋白的合成过程。以及施加机械应力的时间段。氧化应激会阻碍正常的细胞信号通路,以及不同的重要细胞成分(如蛋白质,脂质和细胞DNA),因此会显着干扰胶原蛋白和弹性蛋白的合成过程。以及施加机械应力的时间段。氧化应激会阻碍正常的细胞信号通路,以及蛋白质,脂质和细胞DNA等不同的重要细胞成分,因此会显着干扰胶原蛋白和弹性蛋白的合成过程。
