Damage to genetic material and errors in the functioning of cellular mechanisms disturb genome stability and integrity. Assessment of genomic stability in animals is a very important aspect of breeding work. Unfortunately, harmful instabilities affect the functioning, health and reproductive processes of animals. Obtaining healthy calves is a priority, whatever methods of reproductive biotechnology are applied. The aim of the study was to assess the genomic stability of calves obtained from artificial insemination and OPU/IVP in vitro fertilization. The genomic stability of the calves was evaluated using the comet, sister chromatid exchange, and fragile sites assays. Damage to the genetic material of calves obtained by two reproductive biotechnologies was identified. Identification of instability in animals can be a valuable tool in breeding work and accelerate breeding progress.
遗传物质的损伤和细胞机制功能的错误会扰乱基因组的稳定性和完整性。评估动物的基因组稳定性是繁殖工作的一个非常重要的方面。不幸的是,有害的不稳定性会影响动物的功能、健康和生殖过程。无论应用何种生殖生物技术,获得健康的犊牛都是首要任务。本研究的目的是评估通过人工授精和体外受精的卵母细胞抽吸/体外受精获得的犊牛的基因组稳定性。使用彗星、姐妹染色单体交换和脆性位点分析评估犊牛的基因组稳定性。确定了两种生殖生物技术获得的犊牛的遗传物质损伤。在繁殖工作中,鉴定动物的不稳定性可以成为一种有价值的工具,并加速繁殖进程。
