Abstract

. This study aimed to assess seminal miRNA relationship with seminal apoptotic markers and oxidative stress (OS) in infertile men associated with varicocele (Vx). . In all, 220 subjects were divided into the following groups: fertile normozoospermic men, fertile normozoospermic men with Vx, infertile oligoasthenoteratozoospermic (OAT) men without Vx, and infertile OAT men with Vx. They were subjected to history taking, clinical examination, and semen analysis. In their semen, the following were estimated: miRNA-122, miRNA-181a, and miRNA-34c5 using quantitative real-time PCR, apoptotic markers (BAX, BCL2) protein expression, and OS markers [malondialdehyde (MDA) and glutathione peroxidase (GPx)]. . The mean levels of seminal miRNA-122, miRNA-181a, and miRNA-34c5 were significantly reduced in infertile OAT men with Vx compared with other groups coupled with Vx grade and Vx bilaterality. Seminal miRNA-122, miRNA-181a, and miRNA-34c5 were positively correlated with sperm concentration, total sperm motility, sperm normal morphology, seminal GPx, and seminal BCL2 and negatively correlated with seminal MDA and seminal BAX. . Seminal miRNA-122, miRNA-181a, and miRNA-34c5 are decreased in infertile OAT men with Vx associated with increased Vx grade and Vx bilaterality. In addition, they are positively correlated with sperm parameters and negatively correlated with OS, apoptotic markers.

摘要

本研究旨在评估精索静脉曲张(Vx)相关不育男性精液中微小RNA(miRNA)与精液凋亡标志物及氧化应激(OS)之间的关系。总共220名受试者被分为以下几组:生育力正常的正常精子症男性、患有Vx的生育力正常的正常精子症男性、不患有Vx的不育少弱畸精子症(OAT)男性以及患有Vx的不育OAT男性。对他们进行了病史采集、临床检查和精液分析。在他们的精液中,使用定量实时聚合酶链反应评估了以下指标:miRNA - 122、miRNA - 181a和miRNA - 34c5,凋亡标志物(BAX、BCL2)的蛋白表达以及OS标志物[丙二醛(MDA)和谷胱甘肽过氧化物酶(GPx)]。与其他伴有Vx分级和双侧Vx的组相比,患有Vx的不育OAT男性精液中miRNA - 122、miRNA - 181a和miRNA - 34c5的平均水平显著降低。精液miRNA - 122、miRNA - 1- 1a和miRNA - 34c5与精子浓度、精子总活力、精子正常形态、精液GPx和精液BCL2呈正相关,与精液MDA和精液BAX呈负相关。患有与Vx分级增加和双侧Vx相关的Vx的不育OAT男性精液中miRNA - 122、miRNA - 181a和miRNA - v4c5减少。此外,它们与精子参数呈正相关,与OS、凋亡标志物呈负相关。
