This study aimed to identify the potential peptide candidates and expected proteins associated with gene mutations in Bengal cats and determine if peptidome profiles differ between healthy controls and cats with gene mutations. All animals were evaluated using echocardiography. DNA was isolated and followed by the screening test of gene mutation. The MALDI-TOF mass spectrometry was conducted for analyzing the targeted peptide and protein patterns. The expected protein candidates were searched for within the NCBI database. Our results demonstrated that the gene mutation was dominant in Bengal cats but not in domestic shorthair cats. Correlations between baseline characteristics and echocardiographic parameters were discovered in Bengal cats. Mass spectrometry profiles of the candidate proteins were suspected to accompany the cat with the gene mutation, involving integral protein-membrane, organization of nucleus, DNA replication, and ATP-binding protein. Therefore, gene mutations occur frequently in Bengal cat populations. The high incidence of homozygotes for the mutation supports the causal nature of the mutation. In addition, peptidomics analysis was established for the first time under this condition to promise a complementary technique for the future clinical diagnosis of the mutation associated with physiological variables and cardiac morphology in cats.
本研究旨在鉴定与孟加拉猫基因突变相关的潜在肽段候选物和预期蛋白质,并确定健康对照猫和基因突变猫之间的肽组图谱是否存在差异。所有动物均使用超声心动图进行评估。分离DNA,随后进行基因突变筛查试验。采用基质辅助激光解吸电离飞行时间质谱法分析靶向肽段和蛋白质模式。在NCBI数据库中搜索预期的蛋白质候选物。我们的结果表明,该基因突变在孟加拉猫中占主导地位,而在国内短毛猫中则不然。在孟加拉猫中发现了基线特征与超声心动图参数之间的相关性。怀疑候选蛋白质的质谱图谱与携带该基因突变的猫有关,涉及整合膜蛋白、细胞核组织、DNA复制和ATP结合蛋白。因此,该基因突变在孟加拉猫群体中频繁发生。该突变纯合子的高发生率支持了该突变的因果性质。此外,首次在这种情况下建立了肽组学分析,有望为未来临床诊断与猫的生理变量和心脏形态相关的该突变提供一种补充技术。
