摘要: 旨在探究ADP-核糖基转移酶3(ADP-ribosyl transferase 3,ART3)调控精子发生机制,为改善精液品质,提高家畜繁殖性能提供理论依据。本试验设计了3个ART3抑制剂3-甲氧基苯甲酰胺(3-methoxybenzamide,3-MBA)浓度梯度(0.302、0.906和1.510 mg·mL-1),分别对6~8周龄小鼠进行睾丸注射,并于注射后3 h、6 h、12 h、1 d、2 d、3 d和5 d采集小鼠睾丸和附睾组织,将睾丸组织制成石蜡切片进行HE染色,并对附睾尾精子进行动力学和形态学分析。结果发现,0.302 mg·mL-13-MBA浓度组于注射后3 d小鼠睾丸曲细精管内空泡面积达到最大化,生精细胞减少,且排布散乱不规则,注射后5 d空泡面积减小,生精细胞有恢复趋势,而0.906和1.510 mg·mL-1浓度组于注射后5 d空泡面积最大化,曲细精管出现空管现象;3个剂量组小鼠附睾尾精子密度、活力及前向运动精子均呈时间依赖性降低,畸形精子随时间推移逐渐增加,且精子尾部出现断裂、弯折和卷曲等异常形态。综上表明,ART3可能参与调控生精细胞增殖、分化和迁移及精子尾部形成等精子发生过程。

Abstract: This study aimed to explore the mechanism of ADP-ribosyl transferase 3 (ART3) regulating spermatogenesis, and to provide a theoretical basis for improving semen quality and livestock reproductive performance. In this experiment, three kinds of concentrations of ART3 inhibitor 3-methoxybenzamide (3-MBA) (0.302, 0.906 and 1.510 mg·mL-1) were injected into testis of mice in 3 groups aged 6-8 weeks respectively, the testis and epididymis tissues of each mouse were collected at 3 h, 6 h, 12 h, 1 d, 2 d, 3 d and 5 d after injection. The testis tissues were made into paraffin section for HE staining, and the dynamics and morphology of sperm in epididymis caudal were analyzed. The results showed that the area of vacuoles in the seminiferous tubules of mouse testis was maximized, the spermatogenic cells decreased, and arranged dispersedly and irregularly on 3 d after injection in the treatment of 0.302 mg·mL-1 3-MBA; The area of vacuoles decreased, the spermatogenic cells tended to recover on 5 d after injection; While the area of vacuoles was maximized at 5 d after injection in the treatments of 0.906 and 1.510 mg·mL-1 3-MBA, and the empty seminiferous tubules also appeared. In the 3 concentration groups, the density, motility and progressive of sperms in epididymis caudal was decreased in a time-dependent manner, and the sperms with abnormal morphology in epididymis caudal also gradually increased, and the abnormal morphology of sperm tails such as breakage, bending and curling appeared. In summary, ART3 may be involved in the regulation of spermatogenesis, such as proliferation, differentiation, migration of spermatogenic cells and formation of spermatogenic tail.

Key words: ART3, spermatogenesis, reproductive performance, 3-MBA
