项目摘要
The technical establishment of boar sperm cryopreservation isindispensable for effective breeding of the scarce Okinawan native Agu pig. In this study, the addition of ascorbic acid 2-Ο-α-glucoside(AA-2G) and low-density lipoprotein(LDL) tothe freezing extender reduced the plasma membrane damage in post-thaw Agu sperm as aconsequence of the protection of sperm against extracellular oxidative stress and cold shockdamage, respectively, during cryopreservation. Moreover, treatment with an artificial anti-cell death protein(PTD-FNK protein) prevented the mitochondrial dysfunction leading to the apoptotic-cell death during cryopreservation. Therefore, these results indicate that the post-thaw qualities of fragile Agu sperm is effectively improved throughthe established techniques in this study.
公猪精子冷冻保存的技术建立可以有效地育种冲绳本地Agu Pig。在这项研究中,将抗坏血酸2-o-α-葡萄糖苷(AA-2G)和低密度脂蛋白(LDL)添加到冷冻扩展器中减少了丝膜膜的损害,因为后丝刚的精子是对精子的保护,以抗细胞外氧化物压力和冷震的保护,在此期间分别对壳外氧化物的压力和冷震。此外,用人工抗细胞死亡蛋白(PTD-FNK蛋白)进行治疗阻止了线粒体功能障碍,从而导致冷冻保存过程中凋亡细胞死亡。因此,这些结果表明,通过这项研究的既定技术,有效地提高了脆弱的Agu精子的后诊所质量。
