男性勃起功能障碍的分子生物学研究进展

Molecular biological studies of erectile dysfunction: An update

阴茎勃起功能障碍(ED)是常见的男性疾病,5型磷酸二酯酶(PDE5)抑制剂的问世改善了大部分ED患者的性生活质量,然而其对难治性ED的治疗效果不佳。随着ED分子生物学研究的迅速发展,人们不断地发现新的阴茎勃起相关信号通路,深入阐明各类ED的分子发病机制,并尝试用基因治疗等先进方法,更好地解决甚至从根本上治愈ED。本文将全面综述目前有关ED的分子信号转导通路、常见类型ED的分子发病机制以及ED基因治疗的研究进展。

Erectile dysfunction （ED） , as a common male disease, seriously affects the patients＇sexual life quality. Most ED pa- tients benefit from phosphodiesterase type 5 （PDE5） inhibitors, but some refi＇actory ED sufferers fail to respond to them. With the rapid development of molecular biology, the relevant molecular signaling pathways of penile erection and molecular pathogenesis of ED have been gradually clarified, and attempts have been made at a better management or a complete cure of ED with advanced molecular biological methods such as the gene therapy. This article presents an overview on the research progress in the molecular signaling pathways, molecular pathogenesis, and gene therapy of ED.
