摘要

Endometriosis is a chronic, multifactorial disorder. Reactive oxygen species (ROS) and oxidative stress (OS) contribute to the development of endometriosis by affecting apoptosis-related genes in granulosa cells. N-acetylcysteine (NAC) is an antioxidant that reduces OS. This randomized controlled trial aimed to investigate the effects of NAC on serum levels of superoxide dismutase (SOD) and total antioxidant capacity (TAC), as well as the expression of apoptotic genes in granulosa cells. Infertile women with endometriosis were enrolled and administered either NAC (1200 mg/day; n = 11) or placebo (n = 14). Enzyme-linked immunosorbent assay (ELISA) was used to measure serum SOD and TAC levels. The expression of Bcl-2, Bax, and Caspase-3 genes in granulosa cells was evaluated by Real-Time Polymerase Chain Reaction. NAC treatment increased serum SOD and TAC levels. Additionally, the expression of pro-apoptotic genes Bax and Caspase-3 in granulosa cells decreased compared to the placebo group, while the expression of the anti-apoptotic gene Bcl-2 increased. We conclude that administration of N-acetylcysteine (NAC) can reduce apoptosis in granulosa cells of women with infertility due to endometriosis.
